 Poky
 ====

-Poky is an integration of various components to form a complete prepackaged
-build system and development environment. It features support for building
-customised embedded device style images. There are reference demo images
-featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
-cross-architecture application development using QEMU emulation and a
-standalone toolchain and SDK with IDE integration.
+Poky platform builder is a combined cross build system and development 
+environment. It features support for building X11/Matchbox/GTK based 
+filesystem images for various embedded devices and boards. It also 
+supports cross-architecture application development using QEMU emulation
+and a standalone toolchain and SDK with IDE integration.
+
+Poky has an extensive handbook, the source of which is contained in
+the handbook directory. For compiled HTML or pdf versions of this, 
+see the Poky website http://pokylinux.org.

 Additional information on the specifics of hardware that Poky supports
-is available in README.hardware. Further hardware support can easily be added
-in the form of layers which extend the systems capabilities in a modular way.
-
-As an integration layer Poky consists of several upstream projects such as 
-BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
-e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
-
-The Yocto Project has extensive documentation about the system including a 
-reference manual which can be found at:
-    http://yoctoproject.org/documentation
-
-OpenEmbedded-Core is a layer containing the core metadata for current versions
-of OpenEmbedded. It is distro-less (can build a functional image with
-DISTRO = "nodistro") and contains only emulated machine support.
-
-For information about OpenEmbedded, see the OpenEmbedded website:
-    http://www.openembedded.org/
-
-Where to Send Patches
-=====================
-
-As Poky is an integration repository (built using a tool called combo-layer),
-patches against the various components should be sent to their respective
-upstreams:

-addition to common PC input devices, busses, and so on.
+To reflash the kernel:

-Depending on the device, it can boot from a traditional hard-disk, a USB device,
-or over the network. Writing generated images to physical media is
-straightforward with a caveat for USB devices. The following examples assume the
-target boot device is /dev/sdb, be sure to verify this and use the correct
-device as the following commands are run as root and are not reversable.
+  ARMmon > download kernel tftp zimage 192.168.1.202
+  ARMmon > flash kernel

-USB Device:
-  1. Build a live image. This image type consists of a simple filesystem
-     without a partition table, which is suitable for USB keys, and with the
-     default setup for the genericx86 machine, this image type is built
-     automatically for any image you build. For example:
+where zimage is the name of the kernel on the TFTP server and its IP address is 
+192.168.1.202. The names of the files must be all lowercase.

-     $ bitbake core-image-minimal
+To reflash the initrd/initramfs:

-  2. Use the "dd" utility to write the image to the raw block device. For
-     example:
+  ARMmon > download ramdisk tftp diskimage 192.168.1.202
+  ARMmon > flash ramdisk

-     # dd if=core-image-minimal-genericx86.hddimg of=/dev/sdb
+where diskimage is the name of the initramfs image (a cpio.gz file).

-  If the device fails to boot with "Boot error" displayed, or apparently
-  stops just after the SYSLINUX version banner, it is likely the BIOS cannot
-  understand the physical layout of the disk (or rather it expects a
-  particular layout and cannot handle anything else). There are two possible
-  solutions to this problem:
+To boot the initramfs:

-  1. Change the BIOS USB Device setting to HDD mode. The label will vary by
-     device, but the idea is to force BIOS to read the Cylinder/Head/Sector
-     geometry from the device.
+  ARMmon > ramdisk on
+  ARMmon > bootos "console=ttyS0,38400 rdinit=/sbin/init"

-  2. Without such an option, the BIOS generally boots the device in USB-ZIP
-     mode. To write an image to a USB device that will be bootable in
-     USB-ZIP mode, carry out the following actions:
+To reflash the main image login to the system as user "root", then run:

-     a. Determine the geometry of your USB device using fdisk:
+  # ifconfig eth0 192.168.1.203
+  # tftp -g -r mainimage 192.168.1.202
+  # flash_eraseall /dev/mtd1
+  # nandwrite /dev/mtd1 mainimage

-     # fdisk /dev/sdb
-     Command (m for help): p
+which configures the network interface with the IP address 192.168.1.203,
+downloads the "mainimage" file from the TFTP server at 192.168.1.202, erases
+the flash and then writes the new image to the flash.

-     Disk /dev/sdb: 4011 MB, 4011491328 bytes
-     124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
-     ...
+The main image can then be booted with:

-     Command (m for help): q
+  ARMmon > bootos "console=ttyS0,38400 root=/dev/mtdblock1 rootfstype=jffs2"

-     b. Configure the USB device for USB-ZIP mode:
-     
-     # mkdiskimage -4 /dev/sdb 1019 124 62
+Note that the initramfs image is built by poky in a slightly different mode to
+normal since it uses uclibc. To generate this use a command like:

-     Where 1019, 124 and 62 are the cylinder, head and sectors/track counts
-     as reported by fdisk (substitute the values reported for your device).
-     When the operation has finished and the access LED (if any) on the
-     device stops flashing, remove and reinsert the device to allow the
-     kernel to detect the new partition layout.
+IMAGE_FSTYPES=cpio.gz MACHINE=cm-x270 POKYLIBC=uclibc bitbake poky-image-minimal-mtdutils

-     c. Copy the contents of the image to the USB-ZIP mode device:

-     # mkdir /tmp/image
-     # mkdir /tmp/usbkey
-     # mount -o loop core-image-minimal-genericx86.hddimg  /tmp/image
-     # mount /dev/sdb4 /tmp/usbkey
-     # cp -rf /tmp/image/* /tmp/usbkey
+Compulab EM-X270 (em-x270)
+==========================

-     d. Install the syslinux boot loader:
+Fetch the "Linux - kernel and run-time image (Angstrom)" ZIP file from the
+Compulab website. Inside the images directory of this ZIP file is another ZIP
+file called 'LiveDisk.zip'. Extract this over a cleanly formatted vfat USB flash
+drive. Replace the 'em_x270.img' file with the 'updater-em-x270.ext2' file.

-     # syslinux /dev/sdb4
+Insert this USB disk into the supplied adapter and connect this to the
+board. Whilst holding down the the suspend button press the reset button. The
+board will now boot off the USB key and into a version of Angstrom. On the
+desktop is an icon labelled "Updater". Run this program to launch the updater
+that will flash the Poky kernel and rootfs to the board.

-     e. Unmount everything:

-     # umount /tmp/image
-     # umount /tmp/usbkey
+FreeScale iMX31ADS (mx31ads)
+===========================

-  Install the boot device in the target board and configure the BIOS to boot
-  from it.
+The correct serial port is the top-most female connector to the right of the
+ethernet socket.

-  For more details on the USB-ZIP scenario, see the syslinux documentation:
-  http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=blob_plain;f=doc/usbkey.txt;hb=HEAD
+For uploading data to RedBoot we are going to use tftp. In this example we
+assume that the tftpserver is on 192.168.9.1 and the board is on192.168.9.2. 

+To set the IP address, run:

-Texas Instruments Beaglebone (beaglebone)
-=========================================
+  ip_address -l 192.168.9.2/24 -h 192.168.9.1

-The Beaglebone is an ARM Cortex-A8 development board with USB, Ethernet, 2D/3D
-accelerated graphics, audio, serial, JTAG, and SD/MMC. The Black adds a faster
-CPU, more RAM, eMMC flash and a micro HDMI port. The beaglebone MACHINE is
-tested on the following platforms:
+To download a kernel called "zimage" from the TFTP server, run:

-  o Beaglebone Black A6
-  o Beaglebone A6 (the original "White" model)
+  load -r -b 0x100000 zimage

-The Beaglebone Black has eMMC, while the White does not. Pressing the USER/BOOT
-button when powering on will temporarily change the boot order. But for the sake
-of simplicity, these instructions assume you have erased the eMMC on the Black,
-so its boot behavior matches that of the White and boots off of SD card. To do
-this, issue the following commands from the u-boot prompt:
+To write the kernel to flash run:

-    # mmc dev 1
-    # mmc erase 0 512
+  fis create kernel

-To further tailor these instructions for your board, please refer to the
-documentation at http://www.beagleboard.org/bone and http://www.beagleboard.org/black
+To download a rootfs jffs2 image "rootfs" from the TFTP server, run:

-From a Linux system with access to the image files perform the following steps
-as root, replacing mmcblk0* with the SD card device on your machine (such as sdc
-if used via a usb card reader):
+  load -r -b 0x100000 rootfs

-  1. Partition and format an SD card:
-     # fdisk -lu /dev/mmcblk0
+To write the root filesystem  to flash run:

-     Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
-     255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
-     Units = sectors of 1 * 512 = 512 bytes
+  fis create root

-             Device Boot      Start         End      Blocks  Id System
-     /dev/mmcblk0p1   *          63      144584       72261   c Win95 FAT32 (LBA)
-     /dev/mmcblk0p2          144585      465884      160650  83 Linux
+To load and boot a kernel and rootfs from flash:

-     # mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
-     # mke2fs -j -L "root" /dev/mmcblk0p2
+  fis load kernel
+  exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock2 rootfstype=jffs2 init=linuxrc ip=none"

-  The following assumes the SD card partitions 1 and 2 are mounted at
-  /media/boot and /media/root respectively. Removing the card and reinserting
-  it will do just that on most modern Linux desktop environments.
+To load and boot a kernel from a TFTP server with the rootfs over NFS:

-  The files referenced below are made available after the build in
-  build/tmp/deploy/images.
+  load -r -b 0x100000 zimage
+  exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/nfs nfsroot=192.168.9.1:/mnt/nfsmx31 rw ip=192.168.9.2::192.168.9.1:255.255.255.0"

-  2. Install the boot loaders
-     # cp MLO-beaglebone /media/boot/MLO
-     # cp u-boot-beaglebone.img /media/boot/u-boot.img
+The instructions above are for using the (default) NOR flash on the board,
+there is also 128M of NAND flash. It is possible to install Poky to the NAND 
+flash which gives more space for the rootfs and instructions for using this are
+given below. To switch to the NAND flash:

-  3. Install the root filesystem
-     # tar x -C /media/root -f core-image-$IMAGE_TYPE-beaglebone.tar.bz2
+  factive NAND

-  4. If using core-image-base or core-image-sato images, the SD card is ready
-     and rootfs already contains the kernel, modules and device tree (DTB)
-     files necessary to be booted with U-boot's default configuration, so
-     skip directly to step 8.
-     For core-image-minimal, proceed through next steps.
+This will then restart RedBoot using the NAND rather than the NOR. If you
+have not used the NAND before then it is unlikely that there will be a
+partition table yet. You can get the list of partitions with 'fis list'.

-  5. If using core-image-minimal rootfs, install the modules
-     # tar x -C /media/root -f modules-beaglebone.tgz
+If this shows no partitions then you can create them with:

-  6. If using core-image-minimal rootfs, install the kernel zImage into /boot
-     directory of rootfs
-     # cp zImage-beaglebone.bin /media/root/boot/zImage
+  fis init

-  7. If using core-image-minimal rootfs, also install device tree (DTB) files
-     into /boot directory of rootfs
-     # cp zImage-am335x-bone.dtb /media/root/boot/am335x-bone.dtb
-     # cp zImage-am335x-boneblack.dtb /media/root/boot/am335x-boneblack.dtb
+The output of 'fis list' should now show:

-  8. Unmount the SD partitions, insert the SD card into the Beaglebone, and
-     boot the Beaglebone

+Partitions for the kernel and rootfs need to be created:

-Freescale MPC8315E-RDB (mpc8315e-rdb)
-=====================================
+fis create -l 0x1A0000 -e 0x00100000 kernel
+fis create -l 0x5000000 -e 0x00100000 root

-The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
-software development of network attached storage (NAS) and digital media server
-applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
-includes a built-in security accelerator.
+You may now use the instructions above for flashing. However it is important
+to note that the erase block size for the NAND is different to the NOR so the
+JFFS erase size will need to be changed to 0x4000. Stardard images are built
+for NOR and you will need to build custom images for NAND.

-(Note: you may find it easier to order MPC8315E-RDBA; this appears to be the
-same board in an enclosure with accessories. In any case it is fully
-compatible with the instructions given here.)
+You will also need to update the kernel command line to use the correct root
+filesystem. This should be '/dev/mtdblock7' if you adhere to the partitioning
+scheme shown above. If this fails then you can doublecheck against the output
+from the kernel when it evaluates the available mtd partitions.

-Setup instructions
------------------

-You will need the following:
-* NFS root setup on your workstation
-* TFTP server installed on your workstation
-* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your 
-  PC to UART1
-* Ethernet connected to the first ethernet port on the board
+Marvell PXA3xx Zylonite (zylonite)
+==================================

--- Preparation ---
+These instructions assume the Zylonite is connected to a machine running a TFTP 
+server at address 192.168.123.5 and that a serial link (38400 8N1) is available 
+to access the blob bootloader. The kernel is on the TFTP server as 
+"zylonite-kernel" and the root filesystem jffs2 file is "zylonite-rootfs" and 
+the images are to be saved in NAND flash.

-Note: if you have altered your board's ethernet MAC address(es) from the
-defaults, or you need to do so because you want multiple boards on the same
-network, then you will need to change the values in the dts file (patch
-linux/arch/powerpc/boot/dts/mpc8315erdb.dts within the kernel source). If
-you have left them at the factory default then you shouldn't need to do
-anything here.
+The following commands setup blob:

--- Booting from NFS root ---
+  blob> setip client 192.168.123.4
+  blob> setip server 192.168.123.5

-Load the kernel and dtb (device tree blob), and boot the system as follows:
+To flash the kernel:

- 1. Get the kernel (uImage-mpc8315e-rdb.bin) and dtb (uImage-mpc8315e-rdb.dtb)
-    files from the tmp/deploy directory, and make them available on your TFTP
-    server.
+  blob> tftp zylonite-kernel
+  blob> nandwrite -j 0x80800000 0x60000 0x200000

- 2. Connect the board's first serial port to your workstation and then start up
-    your favourite serial terminal so that you will be able to interact with
-    the serial console. If you don't have a favourite, picocom is suggested:
+To flash the rootfs:

-  $ picocom /dev/ttyUSB0 -b 115200
+  blob> tftp zylonite-rootfs
+  blob> nanderase -j 0x260000 0x5000000
+  blob> nandwrite -j 0x80800000 0x260000 <length>

- 3. Power up or reset the board and press a key on the terminal when prompted
-    to get to the U-Boot command line
+(where <length> is the rootfs size which will be printed by the tftp step)

- 4. Set up the environment in U-Boot:
+To boot the board:

- => setenv ipaddr <board ip>
- => setenv serverip <tftp server ip>
- => setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200
+  blob> nkernel
+  blob> boot

- 5. Download the kernel and dtb, and boot:

- => tftp 1000000 uImage-mpc8315e-rdb.bin
- => tftp 2000000 uImage-mpc8315e-rdb.dtb
- => bootm 1000000 - 2000000
+Logic iMX31 Lite Kit (mx31litekit)
+===============================

--- Booting from JFFS2 root ---
+The easiest method to boot this board is to take an MMC/SD card and format 
+the first partition as ext2, then extract the poky image onto this as root. 
+Assuming the board is network connected, a TFTP server is available at 
+192.168.1.33 and a serial terminal is available (115200 8N1), the following 
+commands will boot a kernel called "mx31kern" from the TFTP server:

- 1. First boot the board with NFS root.
+  losh> ifconfig sm0 192.168.1.203 255.255.255.0 192.168.1.33
+  losh> load raw 0x80100000 0x200000 /tftp/192.168.1.33:mx31kern
+  losh> exec 0x80100000 - 

- 2. Erase the MTD partition which will be used as root:

-    $ flash_eraseall  /dev/mtd3
+Phytec phyCORE-iMX31 (mx31phy)
+==============================

- 3. Copy the JFFS2 image to the MTD partition:
+Support for this board is currently being developed. Experimental jffs2 
+images and a suitable kernel are available and are known to work with the
+board.

-    $ flashcp core-image-minimal-mpc8315e-rdb.jffs2 /dev/mtd3

- 4. Then reboot the board and set up the environment in U-Boot:
+                             Consumer Devices
+                             ================

-    => setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttyS0,115200
+FIC Neo1973 GTA01 smartphone (fic-gta01)
+========================================

+To install Poky on a GTA01 smartphone you will need "dfu-util" tool
+which you can build with "bitbake dfu-util-native" command.

-Ubiquiti Networks EdgeRouter Lite (edgerouter)
-==============================================
+Flashing requires these steps:

-The EdgeRouter Lite is part of the EdgeMax series. It is a MIPS64 router
-(based on the Cavium Octeon processor) with 512MB of RAM, which uses an
-internal USB pendrive for storage.
+  1. Power down the device.
+  2. Connect the device to the host machine via USB.
+  3. Hold AUX key and press Power key. There should be a bootmenu
+     on screen.
+  4. Run "dfu-util -l" to check if the phone is visible on the USB bus. 
+     The output should look like this:

-Setup instructions
------------------
+     dfu-util - (C) 2007 by OpenMoko Inc.
+     This program is Free Software and has ABSOLUTELY NO WARRANTY

-You will need the following:
-* RJ45 -> serial ("rollover") cable connected from your PC to the CONSOLE
-  port on the device
-* Ethernet connected to the first ethernet port on the board
+     Found Runtime: [0x1457:0x5119] devnum=19, cfg=0, intf=2, alt=0, name="USB Device Firmware Upgrade"

-If using NFS as part of the setup process, you will also need:
-* NFS root setup on your workstation
-* TFTP server installed on your workstation (if fetching the kernel from
-  TFTP, see below).
+  5. Flash the kernel with "dfu-util -a kernel -D uImage-2.6.21.6-moko11-r2-fic-gta01.bin"
+  6. Flash rootfs with "dfu-util -a rootfs -D <image>", where <image> is the
+     jffs2 image file to use as the root filesystem 
+     (e.g. ./tmp/deploy/images/poky-image-sato-fic-gta01.jffs2) 

--- Preparation ---

-Build an image (e.g. core-image-minimal) using "edgerouter" as the MACHINE.
-In the following instruction it is based on core-image-minimal. Another target
-may be similiar with it.
+HTC Universal (htcuniversal)
+============================

--- Booting from NFS root / kernel via TFTP ---
+Note: HTC Universal support is highly experimental.

-Load the kernel, and boot the system as follows:
+On the HTC Universal, entirely replacing the Windows installation is not 
+supported, instead Poky is booted from an MMC/SD card from Windows. Once Poky
+has booted, Windows is no longer in memory or active but when power is removed,
+the user will be returned to windows and will need to return to Linux from 
+there.

- 1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
-    directory, and make them available on your TFTP server.
+Once an MMC/SD card is available it is suggested its split into two partitions,
+one for a program called HaRET which lets you boot Linux from within Windows
+and the second for the rootfs. The HaRET partition should be the first partition
+on the card and be vfat formatted. It doesn't need to be large, just enough for
+HaRET and a kernel (say 5MB max). The rootfs should be ext2 and is usually the 
+second partition. The first partition should be vfat so Windows recognises it 
+as if it doesn't, it has been known to reformat cards.

- 2. Connect the board's first serial port to your workstation and then start up
-    your favourite serial terminal so that you will be able to interact with
-    the serial console. If you don't have a favourite, picocom is suggested:
+On the first partition you need three files:

-  $ picocom /dev/ttyS0 -b 115200
+  * a HaRET binary (version 0.5.1 works well and a working version 
+    should be part of the last Poky release)
+  * a kernel renamed to "zImage"
+  * a default.txt which contains:

- 3. Power up or reset the board and press a key on the terminal when prompted
-    to get to the U-Boot command line
+set kernel "zImage"
+set mtype "855"
+set cmdline "root=/dev/mmcblk0p2 rw console=ttyS0,115200n8 console=tty0 rootdelay=5 fbcon=rotate:1"
+boot2

- 4. Set up the environment in U-Boot:
+On the second parition the root file system is extracted as root. A different
+partition layout or other kernel options can be changed in the default.txt file.

- => setenv ipaddr <board ip>
- => setenv serverip <tftp server ip>
+When inserted into the device, Windows should see the card and let you browse
+its contents using File Explorer. Running the HaRET binary will present a dialog
+box (maybe after messages warning about running unsigned binaries) where you 
+select OK and you should then see Poky boot. Kernel messages can be seen by 
+adding psplash=false to the kernel commandline.

- 5. Download the kernel and boot:

- => tftp tftp $loadaddr vmlinux
- => bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
+Nokia 770/N800/N810 Internet Tablets (nokia770 and nokia800)
+============================================================

--- Booting from USB root ---
+Note: Nokia tablet support is highly experimental.

-To boot from the USB disk, you either need to remove it from the edgerouter
-box and populate it from another computer, or use a previously booted NFS
-image and populate from the edgerouter itself.
+The Nokia internet tablet devices are OMAP based tablet formfactor devices 
+with large screens (800x480), wifi and touchscreen.

-Type 1: Mounted USB disk
------------------------
+To flash images to these devices you need the "flasher" utility which can be 
+downloaded from the http://tablets-dev.nokia.com/d3.php?f=flasher-3.0. This 
+utility needs to be run as root and the usb filesystem needs to be mounted 
+although most distributions will have done this for you. Once you have this 
+follow these steps:

-To boot from the USB disk there are two available partitions on the factory
-USB storage. The rest of this guide assumes that these partitions are left
-intact. If you change the partition scheme, you must update your boot method
-appropriately.
+  1. Power down the device.
+  2. Connect the device to the host machine via USB 
+     (connecting power to the device doesn't hurt either).
+  3. Run "flasher -i"
+  4. Power on the device.
+  5. The program should give an indication it's found 
+     a tablet device. If not, recheck the cables, make sure you're 
+     root and usbfs/usbdevfs is mounted.
+  6. Run "flasher -r <image> -k <kernel> -f", where <image> is the
+     jffs2 image file to use as the root filesystem 
+     (e.g. ./tmp/deploy/images/poky-image-sato-nokia800.jffs2) 
+     and <kernel> is the kernel to use 
+     (e.g. ./tmp/deploy/images/zImage-nokia800.bin).
+  7. Run "flasher -R" to reboot the device.
+  8. The device should boot into Poky.

-The standard partitions are:
+The nokia800 images and kernel will run on both the N800 and N810.

-  - 1: vfat partition containing factory kernels
-  - 2: ext3 partition for the root filesystem.

-You can place the kernel on either partition 1, or partition 2, but the roofs
-must go on partition 2 (due to its size).
+Sharp Zaurus SL-C7x0 series (c7x0)
+==================================

-Note: If you place the kernel on the ext3 partition, you must re-create the
-      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
-      cannot read the partition otherwise.
+The Sharp Zaurus c7x0 series (SL-C700, SL-C750, SL-C760, SL-C860, SL-7500)
+are PXA25x based handheld PDAs with VGA screens. To install Poky images on
+these devices follow these steps:

-Steps:
+  1. Obtain an SD/MMC or CF card with a vfat or ext2 filesystem.
+  2. Copy a jffs2 image file (e.g. poky-image-sato-c7x0.jffs2) onto the
+     card as "initrd.bin":

- 1. Remove the USB disk from the edgerouter and insert it into a computer
-    that has access to your build artifacts.
+     $ cp ./tmp/deploy/images/poky-image-sato-c7x0.jffs2 /path/to/my-cf-card/initrd.bin

- 2. Copy the kernel image to the USB storage (assuming discovered as 'sdb' on
-    the development machine):
+  3. Copy an Linux kernel file (zImage-c7x0.bin) onto the card as 
+     "zImage.bin":

-    2a) if booting from vfat
- 
-        # mount /dev/sdb1 /mnt
-        # cp tmp/deploy/images/edgerouter/vmlinux /mnt
-        # umount /mnt
+     $ cp ./tmp/deploy/images/zImage-c7x0.bin /path/to/my-cf-card/zImage.bin

-    2b) if booting from ext3
+  4. Copy an updater script (updater.sh.c7x0) onto the card
+     as "updater.sh":

-        # mkfs.ext3 -I 128 /dev/sdb2
-        # mount /dev/sdb2 /mnt
-        # mkdir /mnt/boot
-        # cp tmp/deploy/images/edgerouter/vmlinux /mnt/boot
-        # umount /mnt
+     $ cp ./tmp/deploy/images/updater.sh.c7x0 /path/to/my-cf-card/updater.sh

- 3. Extract the rootfs to the USB storage ext3 partition
+  5. Power down the Zaurus.
+  6. Hold "OK" key and power on the device. An update menu should appear 
+     (in Japanese).
+  7. Choose "Update" (item 4).
+  8. The next screen will ask for the source, choose the appropriate 
+     card (CF or SD).
+  9. Make sure AC power is connected.
+  10. The next screen asks for confirmation, choose "Yes" (the left button).
+  11. The update process will start, flash the files on the card onto 
+      the device and the device will then reboot into Poky.

-        # mount /dev/sdb2 /mnt
-        # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /mnt
-        # umount /mnt

- 4. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
-    command line:
+Sharp Zaurus SL-C1000 (akita)
+=============================

- 5. Load the kernel and boot:
+The Sharp Zaurus SL-C1000 is a PXA270 based device otherwise similar to the 
+c7x0. To install Poky images on this device follow the instructions for 
+the c7x0 but replace "c7x0" with "akita" where appropriate.

-    5a) vfat boot

-         => fatload usb 0:1 $loadaddr vmlinux
+Sharp Zaurus SL-C3x00 series (spitz)
+====================================

-    5b) ext3 boot
+The Sharp Zaurus SL-C3x00 devices are PXA270 based devices similar
+to akita but with an internal microdrive. The installation procedure 
+assumes a standard microdrive based device where the root (first) 
+partition has been enlarged to fit the image (at least 100MB, 
+400MB for the SDK).

-         => ext2load usb 0:2 $loadaddr boot/vmlinux
- 
-    => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
- 
+The procedure is the same as for the c7x0 and akita models with the 
+following differences:

-Type 2: NFS
-----------
+ 1. Instead of a jffs2 image you need to copy a compressed tarball of the 
+    root fileystem (e.g. poky-image-sato-spitz.tar.gz) onto the
+    card as "hdimage1.tgz":

-Note: If you place the kernel on the ext3 partition, you must re-create the
-      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
-      cannot read the partition otherwise.
+    $ cp ./tmp/deploy/images/poky-image-sato-spitz.tar.gz /path/to/my-cf-card/hdimage1.tgz

-      These boot instructions assume that you have recreated the ext3 filesystem with
-      128 byte inodes, you have an updated uboot or you are running and image capable
-      of making the filesystem on the board itself.
+ 2. You additionally need to copy a special tar utility  (gnu-tar) onto 
+    the card as "gnu-tar":

+    $ cp ./tmp/deploy/images/gnu-tar /path/to/my-cf-card/gnu-tar

- 1. Boot from NFS root

- 2. Mount the USB disk partition 2 and then extract the contents of
-    tmp/deploy/core-image-XXXX.tar.bz2 into it.

-    Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
-    rootfs path on your workstation.
-
-    and then,
-  
-      # mount /dev/sda2 /media/sda2
-      # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
-      # cp vmlinux /media/sda2/boot/vmlinux
-      # umount /media/sda2
-      # reboot
-
- 3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
-    command line:
-
-    # reboot
-
- 4. Load the kernel and boot:
-
-      => ext2load usb 0:2 $loadaddr boot/vmlinux
-      => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)

-Documentation
-=============
-
-This is the directory that contains the BitBake documentation. 
-
-Manual Organization
-===================
-
-Folders exist for individual manuals as follows:
-
-* bitbake-user-manual      - The BitBake User Manual 
-
-Each folder is self-contained regarding content and figures.
-
-If you want to find HTML versions of the BitBake manuals on the web, 
-go to http://www.openembedded.org/wiki/Documentation. 
-
-Makefile
-========
-
-The Makefile processes manual directories to create HTML, PDF,
-tarballs, etc.  Details on how the Makefile work are documented
-inside the Makefile.  See that file for more information.
-
-To build a manual, you run the make command and pass it the name
-of the folder containing the manual's contents. 
-For example, the following command run from the documentation directory 
-creates an HTML and a PDF version of the BitBake User Manual.
-The DOC variable specifies the manual you are making:
-
-     $ make DOC=bitbake-user-manual
-
-template
-========
-Contains various templates, fonts, and some old PNG files.
-
-tools
-=====
-Contains a tool to convert the DocBook files to PDF format.

-    <title>Execution</title>
-
-    <para>
-        The primary purpose for running BitBake is to produce some kind
-        of output such as a single installable package, a kernel, a software
-        development kit, or even a full, board-specific bootable Linux image,
-        complete with bootloader, kernel, and root filesystem.
-        Of course, you can execute the <filename>bitbake</filename>
-        command with options that cause it to execute single tasks,
-        compile single recipe files, capture or clear data, or simply
-        return information about the execution environment.
-    </para>
-
-    <para>
-        This chapter describes BitBake's execution process from start
-        to finish when you use it to create an image.
-        The execution process is launched using the following command
-        form:
-        <literallayout class='monospaced'>
-     $ bitbake <replaceable>target</replaceable>
-        </literallayout>
-        For information on the BitBake command and its options,
-        see
-        "<link linkend='bitbake-user-manual-command'>The BitBake Command</link>"
-        section.
-        <note>
-            <para>
-                Prior to executing BitBake, you should take advantage of available
-                parallel thread execution on your build host by setting the
-                <link linkend='var-BB_NUMBER_THREADS'><filename>BB_NUMBER_THREADS</filename></link>
-                variable in your project's <filename>local.conf</filename>
-                configuration file.
-            </para>
-
-            <para>
-                A common method to determine this value for your build host is to run
-                the following:
-                <literallayout class='monospaced'>
-     $ grep processor /proc/cpuinfo
-                </literallayout>
-                This command returns the number of processors, which takes into
-                account hyper-threading.
-                Thus, a quad-core build host with hyper-threading most likely
-                shows eight processors, which is the value you would then assign to
-                <filename>BB_NUMBER_THREADS</filename>.
-            </para>
-
-            <para>
-                A possibly simpler solution is that some Linux distributions
-                (e.g. Debian and Ubuntu) provide the <filename>ncpus</filename> command.

-        <title>Parsing the Base Configuration Metadata</title>
-
-        <para>
-            The first thing BitBake does is parse base configuration
-            metadata.
-            Base configuration metadata consists of your project's
-            <filename>bblayers.conf</filename> file to determine what
-            layers BitBake needs to recognize, all necessary
-            <filename>layer.conf</filename> files (one from each layer),
-            and <filename>bitbake.conf</filename>.
-            The data itself is of various types:
-            <itemizedlist>
-                <listitem><para><emphasis>Recipes:</emphasis>
-                    Details about particular pieces of software.
-                    </para></listitem>
-                <listitem><para><emphasis>Class Data:</emphasis>
-                    An abstraction of common build information
-                    (e.g. how to build a Linux kernel).

-                <listitem><para><emphasis>Configuration Data:</emphasis>
-                    Machine-specific settings, policy decisions,
-                    and so forth.
-                    Configuration data acts as the glue to bind everything
-                    together.</para></listitem>
-            </itemizedlist>
-        </para>
-
-        <para>
-            The <filename>layer.conf</filename> files are used to
-            construct key variables such as
-            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
-            and
-            <link linkend='var-BBFILES'><filename>BBFILES</filename></link>.
-            <filename>BBPATH</filename> is used to search for
-            configuration and class files under the
-            <filename>conf</filename> and <filename>classes</filename>
-            directories, respectively.
-            <filename>BBFILES</filename> is used to locate both recipe
-            and recipe append files
-            (<filename>.bb</filename> and <filename>.bbappend</filename>).
-            If there is no <filename>bblayers.conf</filename> file,
-            it is assumed the user has set the <filename>BBPATH</filename>
-            and <filename>BBFILES</filename> directly in the environment.
-        </para>
-
-        <para>
-            Next, the <filename>bitbake.conf</filename> file is located
-            using the <filename>BBPATH</filename> variable that was
-            just constructed.
-            The <filename>bitbake.conf</filename> file may also include other
-            configuration files using the
-            <filename>include</filename> or
-            <filename>require</filename> directives.
-        </para>
-
-        <para>
-            Prior to parsing configuration files, Bitbake looks
-            at certain variables, including:

-                <listitem><para>

-            The first four variables in this list relate to how BitBake treats shell
-            environment variables during task execution.
-            By default, BitBake cleans the environment variables and provides tight
-            control over the shell execution environment.
-            However, through the use of these first four variables, you can
-            apply your control regarding the
-            environment variables allowed to be used by BitBake in the shell
-            during execution of tasks.
-            See the
-            "<link linkend='passing-information-into-the-build-task-environment'>Passing Information Into the Build Task Environment</link>"
-            section and the information about these variables in the
-            variable glossary for more information on how they work and
-            on how to use them.
-        </para>
-
-        <para>
-            The base configuration metadata is global
-            and therefore affects all recipes and tasks that are executed.
-        </para>
-
-        <para>
-            BitBake first searches the current working directory for an
-            optional <filename>conf/bblayers.conf</filename> configuration file.
-            This file is expected to contain a
-            <link linkend='var-BBLAYERS'><filename>BBLAYERS</filename></link>
-            variable that is a space-delimited list of 'layer' directories.
-            Recall that if BitBake cannot find a <filename>bblayers.conf</filename>
-            file, then it is assumed the user has set the <filename>BBPATH</filename>
-            and <filename>BBFILES</filename> variables directly in the environment.
-        </para>
-
-        <para>
-            For each directory (layer) in this list, a <filename>conf/layer.conf</filename>
-            file is located and parsed with the
-            <link linkend='var-LAYERDIR'><filename>LAYERDIR</filename></link>
-            variable being set to the directory where the layer was found.
-            The idea is these files automatically set up
-            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
-            and other variables correctly for a given build directory.
-        </para>
-
-        <para>
-            BitBake then expects to find the <filename>conf/bitbake.conf</filename>
-            file somewhere in the user-specified <filename>BBPATH</filename>.
-            That configuration file generally has include directives to pull
-            in any other metadata such as files specific to the architecture,
-            the machine, the local environment, and so forth.
-        </para>
-
-        <para>
-            Only variable definitions and include directives are allowed
-            in BitBake <filename>.conf</filename> files.
-            Some variables directly influence BitBake's behavior.
-            These variables might have been set from the environment
-            depending on the environment variables previously
-            mentioned or set in the configuration files.
-            The
-            "<link linkend='ref-variables-glos'>Variables Glossary</link>"
-            chapter presents a full list of variables.
-        </para>
-
-        <para>
-            After parsing configuration files, BitBake uses its rudimentary
-            inheritance mechanism, which is through class files, to inherit
-            some standard classes.
-            BitBake parses a class when the inherit directive responsible
-            for getting that class is encountered.
-        </para>
-
-        <para>
-            The <filename>base.bbclass</filename> file is always included.
-            Other classes that are specified in the configuration using the
-            <link linkend='var-INHERIT'><filename>INHERIT</filename></link>
-            variable are also included.
-            BitBake searches for class files in a
-            <filename>classes</filename> subdirectory under
-            the paths in <filename>BBPATH</filename> in the same way as
-            configuration files.
-        </para>
-
-        <para>
-            A good way to get an idea of the configuration files and
-            the class files used in your execution environment is to
-            run the following BitBake command:
-            <literallayout class='monospaced'>
-     $ bitbake -e > mybb.log
-            </literallayout>
-            Examining the top of the <filename>mybb.log</filename>
-            shows you the many configuration files and class files
-            used in your execution environment.
-        </para>
-
-        <note>
-            <para>
-                You need to be aware of how BitBake parses curly braces.
-                If a recipe uses a closing curly brace within the function and
-                the character has no leading spaces, BitBake produces a parsing
-                error.
-                If you use a pair of curly braces in a shell function, the
-                closing curly brace must not be located at the start of the line
-                without leading spaces.
-            </para>

-            <para>
-                Here is an example that causes BitBake to produce a parsing
-                error:
-                <literallayout class='monospaced'>
-     fakeroot create_shar() {
-         cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh

-     }
-     EOF
-     }
-                </literallayout>
-                Writing the recipe this way avoids the error:
-                <literallayout class='monospaced'>
-     fakeroot create_shar() {
-         cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh

-            During the configuration phase, BitBake will have set
-            <link linkend='var-BBFILES'><filename>BBFILES</filename></link>.
-            BitBake now uses it to construct a list of recipes to parse,
-            along with any append files (<filename>.bbappend</filename>)
-            to apply.
-            <filename>BBFILES</filename> is a space-separated list of
-            available files and supports wildcards.
-            An example would be:
-            <literallayout class='monospaced'>
-     BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend"
-            </literallayout>
-            BitBake parses each recipe and append file located
-            with <filename>BBFILES</filename> and stores the values of
-            various variables into the datastore.
-            <note>
-                Append files are applied in the order they are encountered in
-                <filename>BBFILES</filename>.
-            </note>
-            For each file, a fresh copy of the base configuration is
-            made, then the recipe is parsed line by line.
-            Any inherit statements cause BitBake to find and
-            then parse class files (<filename>.bbclass</filename>)
-            using
-            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
-            as the search path.
-            Finally, BitBake parses in order any append files found in
-            <filename>BBFILES</filename>.
-        </para>
-
-        <para>
-            One common convention is to use the recipe filename to define
-            pieces of metadata.
-            For example, in <filename>bitbake.conf</filename> the recipe
-            name and version are used to set the variables
-            <link linkend='var-PN'><filename>PN</filename></link> and
-            <link linkend='var-PV'><filename>PV</filename></link>:
-            <literallayout class='monospaced'>
-     PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
-     PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}"
-            </literallayout>
-            In this example, a recipe called "something_1.2.3.bb" would set
-            <filename>PN</filename> to "something" and
-            <filename>PV</filename> to "1.2.3".

-        <para>
-            By the time parsing is complete for a recipe, BitBake
-            has a list of tasks that the recipe defines and a set of
-            data consisting of keys and values as well as
-            dependency information about the tasks.
-        </para>
-
-        <para>
-            BitBake does not need all of this information.
-            It only needs a small subset of the information to make
-            decisions about the recipe.
-            Consequently, BitBake caches the values in which it is
-            interested and does not store the rest of the information.
-            Experience has shown it is faster to re-parse the metadata than to
-            try and write it out to the disk and then reload it.
-        </para>
-
-        <para>
-            Where possible, subsequent BitBake commands reuse this cache of
-            recipe information.
-            The validity of this cache is determined by first computing a
-            checksum of the base configuration data (see
-            <link linkend='var-BB_HASHCONFIG_WHITELIST'><filename>BB_HASHCONFIG_WHITELIST</filename></link>)
-            and then checking if the checksum matches.
-            If that checksum matches what is in the cache and the recipe
-            and class files have not changed, Bitbake is able to use
-            the cache.
-            BitBake then reloads the cached information about the recipe
-            instead of reparsing it from scratch.

-            Recipe file collections exist to allow the user to

-            own local copy of an upstream repository, but with
-            custom modifications that one does not want upstream.
-            Here is an example:

-                The layers mechanism is now the preferred method of collecting

-                While the collections code remains, its main use is to set layer
-                priorities and to deal with overlap (conflicts) between layers.

-
-        <para>
-            Assuming BitBake has been instructed to execute a target
-            and that all the recipe files have been parsed, BitBake
-            starts to figure out how to build the target.
-            BitBake looks through the <filename>PROVIDES</filename> list
-            for each of the recipes.
-            A <filename>PROVIDES</filename> list is the list of names by which
-            the recipe can be known.
-            Each recipe's <filename>PROVIDES</filename> list is created
-            implicitly through the recipe's
-            <link linkend='var-PN'><filename>PN</filename></link> variable
-            and explicitly through the recipe's
-            <link linkend='var-PROVIDES'><filename>PROVIDES</filename></link>
-            variable, which is optional.
-        </para>
-
-        <para>
-            When a recipe uses <filename>PROVIDES</filename>, that recipe's
-            functionality can be found under an alternative name or names other
-            than the implicit <filename>PN</filename> name.
-            As an example, suppose a recipe named <filename>keyboard_1.0.bb</filename>
-            contained the following:
-            <literallayout class='monospaced'>
-     PROVIDES += "fullkeyboard"
-            </literallayout>
-            The <filename>PROVIDES</filename> list for this recipe becomes
-            "keyboard", which is implicit, and "fullkeyboard", which is explicit.
-            Consequently, the functionality found in
-            <filename>keyboard_1.0.bb</filename> can be found under two
-            different names.

-            for figuring out a target's recipes.
-            Because targets might have multiple providers, BitBake needs
-            to prioritize providers by determining provider preferences.
-        </para>
-
-        <para>
-            A common example in which a target has multiple providers
-            is "virtual/kernel", which is on the
-            <filename>PROVIDES</filename> list for each kernel recipe.
-            Each machine often selects the best kernel provider by using a

-            <literallayout class='monospaced'>
-     PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"

-            Bitbake iterates through each target it needs to build and
-            resolves them and their dependencies using this process.
-        </para>
-
-        <para>
-            Understanding how providers are chosen is made complicated by the fact
-            that multiple versions might exist for a given provider.
-            BitBake defaults to the highest version of a provider.
-            Version comparisons are made using the same method as Debian.
-            You can use the
-            <link linkend='var-PREFERRED_VERSION'><filename>PREFERRED_VERSION</filename></link>
-            variable to specify a particular version.
-            You can influence the order by using the
-            <link linkend='var-DEFAULT_PREFERENCE'><filename>DEFAULT_PREFERENCE</filename></link>
-            variable.
-        </para>
-

-            By default, files have a preference of "0".
-            Setting <filename>DEFAULT_PREFERENCE</filename> to "-1" makes the

-            Setting <filename>DEFAULT_PREFERENCE</filename> to "1" makes it
-            likely the recipe is used.
-            <filename>PREFERRED_VERSION</filename> overrides any
-            <filename>DEFAULT_PREFERENCE</filename> setting.
-            <filename>DEFAULT_PREFERENCE</filename> is often used to mark newer
-            and more experimental recipe versions until they have undergone
-            sufficient testing to be considered stable.
-        </para>
-
-        <para>
-            When there are multiple “versions” of a given recipe,
-            BitBake defaults to selecting the most recent
-            version, unless otherwise specified.
-            If the recipe in question has a
-            <link linkend='var-DEFAULT_PREFERENCE'><filename>DEFAULT_PREFERENCE</filename></link>
-            set lower than the other recipes (default is 0), then
-            it will not be selected.
-            This allows the person or persons maintaining
-            the repository of recipe files to specify
-            their preference for the default selected version.
-            Additionally, the user can specify their preferred version.
-        </para>
-
-        <para>
-            If the first recipe is named <filename>a_1.1.bb</filename>, then the

-            Thus, if a recipe named <filename>a_1.2.bb</filename> exists, BitBake

-            <para>
-                It is common for a recipe to provide two versions -- a stable,

-            variable.
-            BitBake continues to fork threads as long as there are tasks ready to run,

-            As each task completes, a timestamp is written to the directory specified by the

-            On subsequent runs, BitBake looks in the build directory within

-            tasks that are already completed unless a timestamp is found to be invalid.
-            Currently, invalid timestamps are only considered on a per
-            recipe file basis.
-            So, for example, if the configure stamp has a timestamp greater than the
-            compile timestamp for a given target, then the compile task would rerun.
-            Running the compile task again, however, has no effect on other providers

-
-        <para>
-            The exact format of the stamps is partly configurable.
-            In modern versions of BitBake, a hash is appended to the
-            stamp so that if the configuration changes, the stamp becomes
-            invalid and the task is automatically rerun.
-            This hash, or signature used, is governed by the signature policy
-            that is configured (see the
-            "<link linkend='checksums'>Checksums (Signatures)</link>"
-            section for information).
-            It is also possible to append extra metadata to the stamp using
-            the "stamp-extra-info" task flag.
-            For example, OpenEmbedded uses this flag to make some tasks machine-specific.

-            Some tasks are marked as "nostamp" tasks.

-            Looking at the expanded shell functions in the run file and
-            the output in the log files is a useful debugging technique.

-            For Python tasks, BitBake executes the task internally and logs
-            information to the controlling terminal.
-            Future versions of BitBake will write the functions to files
-            similar to the way shell tasks are handled.
-            Logging will be handled in a way similar to shell tasks as well.
-        </para>
-
-        <para>
-            The order in which BitBake runs the tasks is controlled by its
-            task scheduler.
-            It is possible to configure the scheduler and define custom
-            implementations for specific use cases.
-            For more information, see these variables that control the
-            behavior:

-            It is possible to have functions run before and after a task's main
-            function.
-            This is done using the "prefuncs" and "postfuncs" flags of the task
-            that lists the functions to run.

-        <title>Checksums (Signatures)</title>
-
-        <para>
-            A checksum is a unique signature of a task's inputs.
-            The signature of a task can be used to determine if a task
-            needs to be run.
-            Because it is a change in a task's inputs that triggers running
-            the task, BitBake needs to detect all the inputs to a given task.
-            For shell tasks, this turns out to be fairly easy because
-            BitBake generates a "run" shell script for each task and
-            it is possible to create a checksum that gives you a good idea of when
-            the task's data changes.
-        </para>
-
-        <para>
-            To complicate the problem, some things should not be included in
-            the checksum.
-            First, there is the actual specific build path of a given task -
-            the working directory.
-            It does not matter if the working directory changes because it should not
-            affect the output for target packages.
-            The simplistic approach for excluding the working directory is to set
-            it to some fixed value and create the checksum for the "run" script.
-            BitBake goes one step better and uses the
-            <link linkend='var-BB_HASHBASE_WHITELIST'><filename>BB_HASHBASE_WHITELIST</filename></link>
-            variable to define a list of variables that should never be included
-            when generating the signatures.
-        </para>
-
-        <para>
-            Another problem results from the "run" scripts containing functions that
-            might or might not get called.
-            The incremental build solution contains code that figures out dependencies
-            between shell functions.
-            This code is used to prune the "run" scripts down to the minimum set,
-            thereby alleviating this problem and making the "run" scripts much more
-            readable as a bonus.
-        </para>
-
-        <para>
-            So far we have solutions for shell scripts.
-            What about Python tasks?
-            The same approach applies even though these tasks are more difficult.
-            The process needs to figure out what variables a Python function accesses
-            and what functions it calls.
-            Again, the incremental build solution contains code that first figures out
-            the variable and function dependencies, and then creates a checksum for the data
-            used as the input to the task.
-        </para>
-
-        <para>
-            Like the working directory case, situations exist where dependencies
-            should be ignored.
-            For these cases, you can instruct the build process to ignore a dependency
-            by using a line like the following:
-            <literallayout class='monospaced'>
-     PACKAGE_ARCHS[vardepsexclude] = "MACHINE"
-            </literallayout>
-            This example ensures that the <filename>PACKAGE_ARCHS</filename> variable does not
-            depend on the value of <filename>MACHINE</filename>, even if it does reference it.
-        </para>
-
-        <para>
-            Equally, there are cases where we need to add dependencies BitBake
-            is not able to find.
-            You can accomplish this by using a line like the following:
-            <literallayout class='monospaced'>
-      PACKAGE_ARCHS[vardeps] = "MACHINE"
-            </literallayout>
-            This example explicitly adds the <filename>MACHINE</filename> variable as a
-            dependency for <filename>PACKAGE_ARCHS</filename>.
-        </para>
-
-        <para>
-            Consider a case with in-line Python, for example, where BitBake is not
-            able to figure out dependencies.
-            When running in debug mode (i.e. using <filename>-DDD</filename>), BitBake
-            produces output when it discovers something for which it cannot figure out
-            dependencies.
-        </para>
-
-        <para>
-            Thus far, this section has limited discussion to the direct inputs into a task.
-            Information based on direct inputs is referred to as the "basehash" in the
-            code.
-            However, there is still the question of a task's indirect inputs - the
-            things that were already built and present in the build directory.
-            The checksum (or signature) for a particular task needs to add the hashes
-            of all the tasks on which the particular task depends.
-            Choosing which dependencies to add is a policy decision.
-            However, the effect is to generate a master checksum that combines the basehash
-            and the hashes of the task's dependencies.
-        </para>
-
-        <para>
-            At the code level, there are a variety of ways both the basehash and the
-            dependent task hashes can be influenced.
-            Within the BitBake configuration file, we can give BitBake some extra information
-            to help it construct the basehash.
-            The following statement effectively results in a list of global variable
-            dependency excludes - variables never included in any checksum.
-            This example uses variables from OpenEmbedded to help illustrate
-            the concept:
-            <literallayout class='monospaced'>
-     BB_HASHBASE_WHITELIST ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH DL_DIR \
-         SSTATE_DIR THISDIR FILESEXTRAPATHS FILE_DIRNAME HOME LOGNAME SHELL TERM \
-         USER FILESPATH STAGING_DIR_HOST STAGING_DIR_TARGET COREBASE PRSERV_HOST \
-         PRSERV_DUMPDIR PRSERV_DUMPFILE PRSERV_LOCKDOWN PARALLEL_MAKE \
-         CCACHE_DIR EXTERNAL_TOOLCHAIN CCACHE CCACHE_DISABLE LICENSE_PATH SDKPKGSUFFIX"
-            </literallayout>
-            The previous example excludes the work directory, which is part of
-            <filename>TMPDIR</filename>.
-        </para>
-
-        <para>
-            The rules for deciding which hashes of dependent tasks to include through
-            dependency chains are more complex and are generally accomplished with a
-            Python function.
-            The code in <filename>meta/lib/oe/sstatesig.py</filename> shows two examples
-            of this and also illustrates how you can insert your own policy into the system
-            if so desired.
-            This file defines the two basic signature generators OpenEmbedded Core
-            uses:  "OEBasic" and "OEBasicHash".
-            By default, there is a dummy "noop" signature handler enabled in BitBake.
-            This means that behavior is unchanged from previous versions.
-            <filename>OE-Core</filename> uses the "OEBasicHash" signature handler by default
-            through this setting in the <filename>bitbake.conf</filename> file:
-            <literallayout class='monospaced'>
-     BB_SIGNATURE_HANDLER ?= "OEBasicHash"
-            </literallayout>
-            The "OEBasicHash" <filename>BB_SIGNATURE_HANDLER</filename> is the same as the
-            "OEBasic" version but adds the task hash to the stamp files.
-            This results in any metadata change that changes the task hash, automatically
-            causing the task to be run again.
-            This removes the need to bump
-            <link linkend='var-PR'><filename>PR</filename></link>
-            values, and changes to metadata automatically ripple across the build.
-        </para>
-
-        <para>
-            It is also worth noting that the end result of these signature generators is to
-            make some dependency and hash information available to the build.
-            This information includes:

-        <para>
-            It is worth noting that BitBake's "-S" option lets you
-            debug Bitbake's processing of signatures.
-            The options passed to -S allow different debugging modes
-            to be used, either using BitBake's own debug functions
-            or possibly those defined in the metadata/signature handler
-            itself.
-            The simplest parameter to pass is "none", which causes a
-            set of signature information to be written out into
-            <filename>STAMP_DIR</filename>
-            corresponding to the targets specified.
-            The other currently available parameter is "printdiff",
-            which causes BitBake to try to establish the closest
-            signature match it can (e.g. in the sstate cache) and then
-            run <filename>bitbake-diffsigs</filename> over the matches
-            to determine the stamps and delta where these two
-            stamp trees diverge.
-            <note>
-                It is likely that future versions of BitBake will
-                provide other signature handlers triggered through
-                additional "-S" parameters.

-            The setscene process enables BitBake to handle "pre-built" artifacts.
-            The ability to handle and reuse these artifacts allows BitBake
-            the luxury of not having to build something from scratch every time.
-            Instead, BitBake can use, when possible, existing build artifacts.
-        </para>
-
-        <para>
-            BitBake needs to have reliable data indicating whether or not an
-            artifact is compatible.
-            Signatures, described in the previous section, provide an ideal
-            way of representing whether an artifact is compatible.
-            If a signature is the same, an object can be reused.
-        </para>
-
-        <para>
-            If an object can be reused, the problem then becomes how to
-            replace a given task or set of tasks with the pre-built artifact.
-            BitBake solves the problem with the "setscene" process.
-        </para>
-
-        <para>
-            When BitBake is asked to build a given target, before building anything,
-            it first asks whether cached information is available for any of the
-            targets it's building, or any of the intermediate targets.
-            If cached information is available, BitBake uses this information instead of
-            running the main tasks.
-        </para>
-
-        <para>
-            BitBake first calls the function defined by the
-            <link linkend='var-BB_HASHCHECK_FUNCTION'><filename>BB_HASHCHECK_FUNCTION</filename></link>
-            variable with a list of tasks and corresponding
-            hashes it wants to build.
-            This function is designed to be fast and returns a list
-            of the tasks for which it believes in can obtain artifacts.
-        </para>
-
-        <para>
-            Next, for each of the tasks that were returned as possibilities,
-            BitBake executes a setscene version of the task that the possible
-            artifact covers.
-            Setscene versions of a task have the string "_setscene" appended to the
-            task name.
-            So, for example, the task with the name <filename>xxx</filename> has
-            a setscene task named <filename>xxx_setscene</filename>.
-            The setscene version of the task executes and provides the necessary
-            artifacts returning either success or failure.
-        </para>
-
-        <para>
-            As previously mentioned, an artifact can cover more than one task.
-            For example, it is pointless to obtain a compiler if you
-            already have the compiled binary.
-            To handle this, BitBake calls the
-            <link linkend='var-BB_SETSCENE_DEPVALID'><filename>BB_SETSCENE_DEPVALID</filename></link>
-            function for each successful setscene task to know whether or not it needs
-            to obtain the dependencies of that task.
-        </para>
-
-        <para>
-            Finally, after all the setscene tasks have executed, BitBake calls the

-            <link linkend='var-BB_SETSCENE_VERIFY_FUNCTION'><filename>BB_SETSCENE_VERIFY_FUNCTION</filename></link>
-            with the list of tasks BitBake thinks has been "covered".
-            The metadata can then ensure that this list is correct and can
-            inform BitBake that it wants specific tasks to be run regardless

-
-    <para>
-        BitBake's fetch module is a standalone piece of library code
-        that deals with the intricacies of downloading source code
-        and files from remote systems.
-        Fetching source code is one of the cornerstones of building software.
-        As such, this module forms an important part of BitBake.
-    </para>
-
-    <para>
-        The current fetch module is called "fetch2" and refers to the
-        fact that it is the second major version of the API.
-        The original version is obsolete and has been removed from the codebase.
-        Thus, in all cases, "fetch" refers to "fetch2" in this
-        manual.
-    </para>
-
-    <section id='the-download-fetch'>
-        <title>The Download (Fetch)</title>
-
-        <para>
-            BitBake takes several steps when fetching source code or files.
-            The fetcher codebase deals with two distinct processes in order:
-            obtaining the files from somewhere (cached or otherwise)
-            and then unpacking those files into a specific location and
-            perhaps in a specific way.
-            Getting and unpacking the files is often optionally followed
-            by patching.
-            Patching, however, is not covered by this module.
-        </para>
-
-        <para>
-            The code to execute the first part of this process, a fetch,
-            looks something like the following:
-            <literallayout class='monospaced'>
-     src_uri = (d.getVar('SRC_URI', True) or "").split()
-     fetcher = bb.fetch2.Fetch(src_uri, d)
-     fetcher.download()
-            </literallayout>
-            This code sets up an instance of the fetch class.
-            The instance uses a space-separated list of URLs from the
-            <link linkend='var-SRC_URI'><filename>SRC_URI</filename></link>
-            variable and then calls the <filename>download</filename>
-            method to download the files.
-        </para>
-
-        <para>
-            The instantiation of the fetch class is usually followed by:
-            <literallayout class='monospaced'>
-     rootdir = l.getVar('WORKDIR', True)
-     fetcher.unpack(rootdir)
-            </literallayout>
-            This code unpacks the downloaded files to the
-            specified by <filename>WORKDIR</filename>.
-            <note>
-                For convenience, the naming in these examples matches
-                the variables used by OpenEmbedded.
-                If you want to see the above code in action, examine
-                the OpenEmbedded class file <filename>base.bbclass</filename>.
-            </note>
-            The <filename>SRC_URI</filename> and <filename>WORKDIR</filename>
-            variables are not hardcoded into the fetcher, since those fetcher
-            methods can be (and are) called with different variable names.
-            In OpenEmbedded for example, the shared state (sstate) code uses
-            the fetch module to fetch the sstate files.
-        </para>
-
-        <para>
-            When the <filename>download()</filename> method is called,
-            BitBake tries to resolve the URLs by looking for source files
-            in a specific search order:

-                    BitBake first uses pre-mirrors to try and find source files.

-            For each URL passed to the fetcher, the fetcher
-            calls the submodule that handles that particular URL type.
-            This behavior can be the source of some confusion when you
-            are providing URLs for the <filename>SRC_URI</filename>
-            variable.
-            Consider the following two URLs:
-            <literallayout class='monospaced'>
-     http://git.yoctoproject.org/git/poky;protocol=git
-     git://git.yoctoproject.org/git/poky;protocol=http
-            </literallayout>
-            In the former case, the URL is passed to the
-            <filename>wget</filename> fetcher, which does not
-            understand "git".
-            Therefore, the latter case is the correct form since the
-            Git fetcher does know how to use HTTP as a transport.

-            Here are some examples that show commonly used mirror

-            It is useful to note that BitBake supports
-            cross-URLs.
-            It is possible to mirror a Git repository on an HTTP
-            server as a tarball.
-            This is what the <filename>git://</filename> mapping in
-            the previous example does.

-            Since network accesses are slow, Bitbake maintains a
-            cache of files downloaded from the network.
-            Any source files that are not local (i.e.
-            downloaded from the Internet) are placed into the download
-            directory, which is specified by the

-            File integrity is of key importance for reproducing builds.
-            For non-local archive downloads, the fetcher code can verify
-            SHA-256 and MD5 checksums to ensure the archives have been
-            downloaded correctly.
-            You can specify these checksums by using the
-            <filename>SRC_URI</filename> variable with the appropriate
-            varflags as follows:
-            <literallayout class='monospaced'>
-     SRC_URI[md5sum] = "<replaceable>value</replaceable>"
-     SRC_URI[sha256sum] = "<replaceable>value</replaceable>"
-            </literallayout>
-            You can also specify the checksums as parameters on the
-            <filename>SRC_URI</filename> as shown below:
-            <literallayout class='monospaced'>
-     SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d"
-            </literallayout>
-            If multiple URIs exist, you can specify the checksums either
-            directly as in the previous example, or you can name the URLs.
-            The following syntax shows how you name the URIs:
-            <literallayout class='monospaced'>
-     SRC_URI = "http://example.com/foobar.tar.bz2;name=foo"
-     SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d
-            </literallayout>
-            After a file has been downloaded and has had its checksum checked,
-            a ".done" stamp is placed in <filename>DL_DIR</filename>.
-            BitBake uses this stamp during subsequent builds to avoid
-            downloading or comparing a checksum for the file again.
-            <note>
-                It is assumed that local storage is safe from data corruption.
-                If this were not the case, there would be bigger issues to worry about.

-                    are unpacked.
-                    If set to "0", the unpack stage leaves the file alone.
-                    This parameter is useful when you want an archive to be

-            As mentioned, the Git fetcher has its own unpack method that

-
-        <para>
-            As mentioned earlier, the URL prefix determines which

-            Each submodule can support different URL parameters,
-            which are described in the following sections.

-                This submodule handles URLs that begin with
-                <filename>file://</filename>.
-                The filename you specify within the URL can be
-                either an absolute or relative path to a file.
-                If the filename is relative, the contents of the
-                <link linkend='var-FILESPATH'><filename>FILESPATH</filename></link>
-                variable is used in the same way
-                <filename>PATH</filename> is used to find executables.
-                Failing that,
-                <link linkend='var-FILESDIR'><filename>FILESDIR</filename></link>
-                is used to find the appropriate relative file.
-                <note>
-                    <filename>FILESDIR</filename> is deprecated and can
-                    be replaced with <filename>FILESPATH</filename>.
-                    Because <filename>FILESDIR</filename> is likely to be

-                </note>
-                If the file cannot be found, it is assumed that it is available in

-                This fetcher obtains files from web and FTP servers.

-                The executable and parameters used are specified by the

-                The fetcher supports a parameter "downloadfilename" that
-                allows the name of the downloaded file to be specified.
-                Specifying the name of the downloaded file is useful

-                <link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
-                when dealing with multiple files that have the same name.

-            </para>
-            <note>
-               Because URL parameters are delimited by semi-colons, this can
-               introduce ambiguity when parsing URLs that also contain semi-colons,
-               for example:
-                <literallayout class='monospaced'>
-     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git;a=snapshot;h=a5dd47"
-                </literallayout>
-               Such URLs should should be modified by replacing semi-colons with '&amp;' characters:
-               <literallayout class='monospaced'>
-     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&amp;a=snapshot&amp;h=a5dd47"
-                </literallayout>
-                In most cases this should work. Treating semi-colons and '&amp;' in queries
-                identically is recommended by the World Wide Web Consortium (W3C).
-                Note that due to the nature of the URL, you may have to specify the name
-                of the downloaded file as well:
-              <literallayout class='monospaced'>
-     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&amp;a=snapshot&amp;h=a5dd47;downloadfilename=myfile.bz2"

-                This fetcher submodule fetches code from the Git
-                source control system.
-                The fetcher works by creating a bare clone of the
-                remote into
-                <link linkend='var-GITDIR'><filename>GITDIR</filename></link>,
-                which is usually <filename>DL_DIR/git2</filename>.
-                This bare clone is then cloned into the work directory during the
-                unpack stage when a specific tree is checked out.
-                This is done using alternates and by reference to
-                minimize the amount of duplicate data on the disk and
-                make the unpack process fast.
-                The executable used can be set with

-                        If a hostname is not set, the Git protocol is "file".
-                        You can also use "http", "https", "ssh" and "rsync".

-                        You should set this parameter to "1" if
-                        revisions can become detached from branches.
-                        In this case, the source mirror tarball is done per

-                        Rebasing the upstream Git repository could cause the
-                        current revision to disappear from the upstream repository.
-                        This option reminds the fetcher to preserve the local cache

-                        Only the raw Git metadata is provided.

-                        For that reason, tags are often not used.
-                        As far as Git is concerned, the "tag" parameter behaves

-                By default, the fetcher creates a configuration specification.
-                If you want this specification written to an area other than the default,
-                use the <filename>CCASE_CUSTOM_CONFIG_SPEC</filename> variable
-                in your recipe to define where the specification is written.

-                    However, <filename>SRCREV</filename> is still used to label the

-            This appendix demonstrates, in tutorial form, Hello

-
-        <para>
-            First, you need to be sure that you can run BitBake.
-            Set your working directory to where your local BitBake
-            files are and run the following command:
-            <literallayout class='monospaced'>
-     $ ./bin/bitbake --version
-     BitBake Build Tool Core version 1.23.0, bitbake version 1.23.0
-            </literallayout>
-            The console output tells you what version you are running.
-        </para>
-
-        <para>
-            The recommended method to run BitBake is from a directory of your
-            choice.
-            To be able to run BitBake from any directory, you need to add the
-            executable binary to your binary to your shell's environment
-            <filename>PATH</filename> variable.
-            First, look at your current <filename>PATH</filename> variable
-            by entering the following:
-            <literallayout class='monospaced'>
-     $ echo $PATH
-            </literallayout>
-            Next, add the directory location for the BitBake binary to the
-            <filename>PATH</filename>.
-            Here is an example that adds the
-            <filename>/home/scott-lenovo/bitbake/bin</filename> directory
-            to the front of the <filename>PATH</filename> variable:
-            <literallayout class='monospaced'>
-     $ export PATH=/home/scott-lenovo/bitbake/bin:$PATH
-            </literallayout>
-            You should now be able to enter the <filename>bitbake</filename>
-            command from the command line while working from any directory.

-            The overall goal of this exercise is to build a
-            complete "Hello World" example utilizing task and layer
-            concepts.
-            Because this is how modern projects such as OpenEmbedded and
-            the Yocto Project utilize BitBake, the example
-            provides an excellent starting point for understanding
-            BitBake.

-
-        <para>
-            To help you understand how to use BitBake to build targets,
-            the example starts with nothing but the <filename>bitbake</filename>
-            command, which causes BitBake to fail and report problems.
-            The example progresses by adding pieces to the build to
-            eventually conclude with a working, minimal "Hello World"
-            example.

-            As stated earlier, the goal of this example
-            is to eventually compile "Hello World".
-            However, it is unknown what BitBake needs and what you have
-            to provide in order to achieve that goal.
-            Recall that BitBake utilizes three types of metadata files:
-            <link linkend='configuration-files'>Configuration Files</link>,
-            <link linkend='classes'>Classes</link>, and
-            <link linkend='recipes'>Recipes</link>.
-            But where do they go?
-            How does BitBake find them?
-            BitBake's error messaging helps you answer these types of questions
-            and helps you better understand exactly what is going on.

-            <listitem><para><emphasis>Create a Project Directory:</emphasis>
-                First, set up a directory for the "Hello World" project.
-                Here is how you can do so in your home directory:
-                <literallayout class='monospaced'>
-     $ mkdir ~/hello
-     $ cd ~/hello
-                </literallayout>
-                This is the directory that BitBake will use to do all of
-                its work.
-                You can use this directory to keep all the metafiles needed
-                by BitBake.
-                Having a project directory is a good way to isolate your
-                project.

-                <literallayout class='monospaced'>
-     $ bitbake
-     The BBPATH variable is not set and bitbake did not

-                earlier in the appendix.
-                You should realize, though, that it is much more flexible to set the

-     $ BBPATH="<replaceable>projectdirectory</replaceable>"

-                Use your actual project directory in the command.

-                <note>
-                    When specifying your project directory, do not use the

-        Welcome to the BitBake User Manual.
-        This manual provides information on the BitBake tool.
-        The information attempts to be as independent as possible regarding
-        systems that use BitBake, such as OpenEmbedded and the
-        Yocto Project.
-        In some cases, scenarios or examples within the context of
-        a build system are used in the manual to help with understanding.
-        For these cases, the manual clearly states the context.

-        <para>
-            Fundamentally, BitBake is a generic task execution
-            engine that allows shell and Python tasks to be run
-            efficiently and in parallel while working within
-            complex inter-task dependency constraints.
-            One of BitBake's main users, OpenEmbedded, takes this core
-            and builds embedded Linux software stacks using
-            a task-oriented approach.

-        <para>
-            BitBake was originally a part of the OpenEmbedded project.
-            It was inspired by the Portage package management system
-            used by the Gentoo Linux distribution.
-            On December 7, 2004, OpenEmbedded project team member
-            Chris Larson split the project into two distinct pieces:
-            <itemizedlist>
-                <listitem><para>BitBake, a generic task executor</para></listitem>
-                <listitem><para>OpenEmbedded, a metadata set utilized by
-                    BitBake</para></listitem>
-            </itemizedlist>
-            Today, BitBake is the primary basis of the
-            <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink>
-            project, which is being used to build and maintain Linux
-            distributions such as the
-            <ulink url='http://www.angstrom-distribution.org/'>Angstrom Distribution</ulink>,
-            and which is also being used as the build tool for Linux projects
-            such as the
-            <ulink url='http://www.yoctoproject.org'>Yocto Project</ulink>.
-        </para>
-
-        <para>
-            Prior to BitBake, no other build tool adequately met the needs of
-            an aspiring embedded Linux distribution.
-            All of the build systems used by traditional desktop Linux
-            distributions lacked important functionality, and none of the
-            ad hoc Buildroot-based systems, prevalent in the
-            embedded space, were scalable or maintainable.

-            BitBake satisfies all the original requirements and many more

-            reflect the additional requirements.
-            Flexibility and power have always been the priorities.
-            BitBake is highly extensible and supports embedded Python code and

-
-        <para>
-            BitBake is a program written in the Python language.
-            At the highest level, BitBake interprets metadata, decides
-            what tasks are required to run, and executes those tasks.
-            Similar to GNU Make, BitBake controls how software is
-            built.
-            GNU Make achieves its control through "makefiles", while
-            BitBake uses "recipes".

-
-        <para>
-            BitBake extends the capabilities of a simple
-            tool like GNU Make by allowing for the definition of much more
-            complex tasks, such as assembling entire embedded Linux
-            distributions.

-                Within the context of BitBake, or any project utilizing BitBake
-                as its build system, files with the <filename>.bb</filename>
-                extension are referred to as recipes.
-                <note>
-                    The term "package" is also commonly used to describe recipes.
-                    However, since the same word is used to describe packaged
-                    output from a project, it is best to maintain a single
-                    descriptive term - "recipes".
-                    Put another way, a single "recipe" file is quite capable
-                    of generating a number of related but separately installable
-                    "packages".
-                    In fact, that ability is fairly common.

-                Configuration files, which are denoted by the

-            <para>
-                Layers allow you to isolate different types of
-                customizations from each other.
-                While you might find it tempting to keep everything in one layer
-                when working on a single project, the more modular you organize
-                your metadata, the easier it is to cope with future changes.
-            </para>
-
-            <para>
-                To illustrate how you can use layers to keep things modular,
-                consider customizations you might make to support a specific target machine.
-                These types of customizations typically reside in a special layer,
-                rather than a general layer, called a Board Support Package (BSP)
-                Layer.
-                Furthermore, the machine customizations should be isolated from
-                recipes and metadata that support a new GUI environment, for
-                example.
-                This situation gives you a couple of layers: one for the machine
-                configurations and one for the GUI environment.
-                It is important to understand, however, that the BSP layer can still
-                make machine-specific additions to recipes within
-                the GUI environment layer without polluting the GUI layer itself
-                with those machine-specific changes.
-                You can accomplish this through a recipe that is a BitBake append
-                (<filename>.bbappend</filename>) file.

-            </para>
-
-            <para>
-                BitBake expects every append file to have a corresponding recipe file.
-                Furthermore, the append file and corresponding recipe file
-                must use the same root filename.
-                The filenames can differ only in the file type suffix used
-                (e.g. <filename>formfactor_0.0.bb</filename> and
-                <filename>formfactor_0.0.bbappend</filename>).
-            </para>
-
-            <para>
-                Information in append files extends or

-            </para>
-
-            <para>
-                When you name an append file, you can use the
-                wildcard character (%) to allow for matching recipe names.
-                For example, suppose you have an append file named
-                as follows:
-                <literallayout class='monospaced'>
-     busybox_1.21.%.bbappend
-                </literallayout>
-                That append file would match any <filename>busybox_1.21.x.bb</filename>
-                version of the recipe.
-                So, the append file would match the following recipe names:
-                <literallayout class='monospaced'>
-     busybox_1.21.1.bb
-     busybox_1.21.2.bb
-     busybox_1.21.3.bb
-                </literallayout>
-                If the <filename>busybox</filename> recipe was updated to
-                <filename>busybox_1.3.0.bb</filename>, the append name would not
-                match.
-                However, if you named the append file
-                <filename>busybox_1.%.bbappend</filename>, then you would have a match.
-            </para>
-
-            <para>
-                In the most general case, you could name the append file something as
-                simple as <filename>busybox_%.bbappend</filename> to be entirely

-                    Executing tasks for a single recipe file is relatively simple.
-                    You specify the file in question, and BitBake parses

-                    If you do not specify a task, BitBake executes the default
-                    task, which is "build”.
-                    BitBake obeys inter-task dependencies when doing

-   Generic XHTML / DocBook XHTML CSS Stylesheet.
-
-   Browser wrangling and typographic design by
-      Oyvind Kolas / pippin@gimp.org
-
-   Customised for Poky by
-      Matthew Allum / mallum@o-hand.com
-
-   Thanks to:
-     Liam R. E. Quin
-     William Skaggs
-     Jakub Steiner
-
-   Structure
-   ---------
-
-   The stylesheet is divided into the following sections:
-
-       Positioning
-          Margins, paddings, width, font-size, clearing.
-       Decorations
-          Borders, style
-       Colors
-          Colors
-       Graphics
-          Graphical backgrounds
-       Nasty IE tweaks
-          Workarounds needed to make it work in internet explorer,
-          currently makes the stylesheet non validating, but up until
-          this point it is validating.
-       Mozilla extensions
-          Transparency for footer
-	  Rounded corners on boxes

+        <title>Introduction</title>
+        <section>
+            <title>Overview</title>
+            <para>BitBake is, at its simplest, a tool for executing
+tasks and managing metadata.  As such, its similarities to GNU make and other
+build tools are readily apparent.  It was inspired by Portage, the package management system used by the Gentoo Linux distribution.  BitBake is the basis of the <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink> project, which is being used to build and maintain a number of embedded Linux distributions, including OpenZaurus and Familiar.</para>
+        </section>
+        <section>
+            <title>Background and Goals</title>
+            <para>Prior to BitBake, no other build tool adequately met
+the needs of an aspiring embedded Linux distribution.  All of the
+buildsystems used by traditional desktop Linux distributions lacked
+important functionality, and none of the ad-hoc
+<emphasis>buildroot</emphasis> systems, prevalent in the
+embedded space, were scalable or maintainable.</para>
+
+      <para>Some important goals for BitBake were:
+            <itemizedlist>
+                <listitem><para>Handle crosscompilation.</para></listitem>
+                <listitem><para>Handle interpackage dependencies (build time on target architecture, build time on native architecture, and runtime).</para></listitem>
+                <listitem><para>Support running any number of tasks within a given package, including, but not limited to, fetching upstream sources, unpacking them, patching them, configuring them, et cetera.</para></listitem>
+                <listitem><para>Must be linux distribution agnostic (both build and target).</para></listitem>
+                <listitem><para>Must be architecture agnostic</para></listitem>
+                <listitem><para>Must support multiple build and target operating systems (including cygwin, the BSDs, etc).</para></listitem>
+                <listitem><para>Must be able to be self contained, rather than tightly integrated into the build machine's root filesystem.</para></listitem>
+                <listitem><para>There must be a way to handle conditional metadata (on target architecture, operating system, distribution, machine).</para></listitem>
+                <listitem><para>It must be easy for the person using the tools to supply their own local metadata and packages to operate against.</para></listitem>
+                <listitem><para>Must make it easy to collaborate
+between multiple projects using BitBake for their
+builds.</para></listitem>
+		<listitem><para>Should provide an inheritance mechanism to
+share common metadata between many packages.</para></listitem>
+                <listitem><para>Et cetera...</para></listitem>
+            </itemizedlist>
+        </para>
+        <para>BitBake satisfies all these and many more.  Flexibility and power have always been the priorities.  It is highly extensible, supporting embedded Python code and execution of any arbitrary tasks.</para>
+        </section>
+    </chapter>
+    <chapter>
+        <title>Metadata</title>
+        <section>
+            <title>Description</title>
+            <itemizedlist>
+                <para>BitBake metadata can be classified into 3 major areas:</para>
+                <listitem>
+                    <para>Configuration Files</para>
+                </listitem>
+                <listitem>
+                    <para>.bb Files</para>
+                </listitem>
+                <listitem>
+                    <para>Classes</para>
+                </listitem>
+            </itemizedlist>
+            <para>What follows are a large number of examples of BitBake metadata.  Any syntax which isn't supported in any of the aforementioned areas will be documented as such.</para>
+            <section>
+                <title>Basic variable setting</title>
+                <para><screen><varname>VARIABLE</varname> = "value"</screen></para>
+                <para>In this example, <varname>VARIABLE</varname> is <literal>value</literal>.</para>
+            </section>
+            <section>
+                <title>Variable expansion</title>
+                <para>BitBake supports variables referencing one another's contents using a syntax which is similar to shell scripting</para>
+                <para><screen><varname>A</varname> = "aval"
+<varname>B</varname> = "pre${A}post"</screen></para>
+                <para>This results in <varname>A</varname> containing <literal>aval</literal> and <varname>B</varname> containing <literal>preavalpost</literal>.</para>
+            </section>
+            <section>
+                <title>Setting a default value (?=)</title>
+                <para><screen><varname>A</varname> ?= "aval"</screen></para>
+                <para>If <varname>A</varname> is set before the above is called, it will retain it's previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>.  Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
+            </section>
+            <section>
+                <title>Setting a default value (??=)</title>
+                <para><screen><varname>A</varname> ??= "somevalue"</screen></para>
+                <para><screen><varname>A</varname> ??= "someothervalue"</screen></para>
+                <para>If <varname>A</varname> is set before the above, it will retain that value.  If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>.  This is a lazy version of ??=, in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used.</para>
+            </section>
+            <section>
+                <title>Immediate variable expansion (:=)</title>
+                <para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>
+                <para><screen><varname>T</varname> = "123"
+<varname>A</varname> := "${B} ${A} test ${T}"
+<varname>T</varname> = "456"
+<varname>B</varname> = "${T} bval"
+
+<varname>C</varname> = "cval"
+<varname>C</varname> := "${C}append"</screen></para>
+                <para>In that example, <varname>A</varname> would contain <literal> test 123</literal>, <varname>B</varname> would contain <literal>456 bval</literal>, and <varname>C</varname> would be <literal>cvalappend</literal>.</para>
+            </section>
+            <section>

+                <para><screen><varname>B</varname> = "bval"
+<varname>B</varname> += "additionaldata"
+<varname>C</varname> = "cval"
+<varname>C</varname> =+ "test"</screen></para>
+                <para>In this example, <varname>B</varname> is now <literal>bval additionaldata</literal> and <varname>C</varname> is <literal>test cval</literal>.</para>
+            </section>
+            <section>
+                <title>Appending (.=) and prepending (=.) without spaces</title>
+                    <para><screen><varname>B</varname> = "bval"
+<varname>B</varname> .= "additionaldata"
+<varname>C</varname> = "cval"
+<varname>C</varname> =. "test"</screen></para>
+                <para>In this example, <varname>B</varname> is now <literal>bvaladditionaldata</literal> and <varname>C</varname> is <literal>testcval</literal>. In contrast to the above Appending and Prepending operators no additional space
+will be introduced.</para>
+            </section>
+            <section>
+                <title>Conditional metadata set</title>
+                <para>OVERRIDES is a <quote>:</quote> separated variable containing each item you want to satisfy conditions.  So, if you have a variable which is conditional on <quote>arm</quote>, and <quote>arm</quote> is in OVERRIDES, then the <quote>arm</quote> specific version of the variable is used rather than the non-conditional version.  Example:</para>
+                <para><screen><varname>OVERRIDES</varname> = "architecture:os:machine"
+<varname>TEST</varname> = "defaultvalue"
+<varname>TEST_os</varname> = "osspecificvalue"
+<varname>TEST_condnotinoverrides</varname> = "othercondvalue"</screen></para>
+                <para>In this example, <varname>TEST</varname> would be <literal>osspecificvalue</literal>, due to the condition <quote>os</quote> being in <varname>OVERRIDES</varname>.</para>
+            </section>
+            <section>
+                <title>Conditional appending</title>
+                <para>BitBake also supports appending and prepending to variables based on whether something is in OVERRIDES.  Example:</para>
+                <para><screen><varname>DEPENDS</varname> = "glibc ncurses"
+<varname>OVERRIDES</varname> = "machine:local"
+<varname>DEPENDS_append_machine</varname> = " libmad"</screen></para>
+                <para>In this example, <varname>DEPENDS</varname> is set to <literal>glibc ncurses libmad</literal>.</para>
+            </section>
+            <section>
+                <title>Inclusion</title>
+                <para>Next, there is the <literal>include</literal> directive, which causes BitBake to parse in whatever file you specify, and insert it at that location, which is not unlike <command>make</command>.  However, if the path specified on the <literal>include</literal> line is a relative path, BitBake will locate the first one it can find within <envar>BBPATH</envar>.</para>
+            </section>
+            <section>
+                <title>Requiring Inclusion</title>
+                <para>In contrast to the <literal>include</literal> directive, <literal>require</literal> will
+raise an ParseError if the to be included file can not be found. Otherwise it will behave just like the <literal>
+include</literal> directive.</para>

A given bbclass is located by searching for classes/filename.oeclass in <envar>BBPATH</envar>, where filename is what you inherited.</para>

As an example, setting <screen>BBCLASSEXTEND = "native"</screen> results in a second incarnation of the current recipe being available.  This second incarantion will have the "native" class inherited.</para>
+                <para>The second feature is <varname>BBVERSIONS</varname>.  This variable allows a single recipe to be able to build multiple versions of a project from a single recipe file, and allows you to specify conditional metadata (using the <varname>OVERRIDES</varname> mechanism) for a single version, or an optionally named range of versions:</para>
+                <para><screen>BBVERSIONS = "1.0 2.0 git"

+                <para>Note that the name of the range will default to the original version of the recipe, so given OE, a recipe file of foo_1.0.0+.bb will default the name of its versions to 1.0.0+.  This is useful, as the range name is not only placed into overrides, it's also made available for the metadata to use in the form of the <varname>BPV</varname> variable, for use in file:// search paths (<varname>FILESPATH</varname>).</para>

+usage: bitbake [options] [package ...]
+
+Executes the specified task (default is 'build') for a given set of BitBake files.
+It expects that BBFILES is defined, which is a space separated list of files to
+be executed.  BBFILES does support wildcards.
+Default BBFILES are the .bb files in the current directory.
+
+options:
+  --version             show program's version number and exit
+  -h, --help            show this help message and exit
+  -b BUILDFILE, --buildfile=BUILDFILE
+                        execute the task against this .bb file, rather than a
+                        package from BBFILES.
+  -k, --continue        continue as much as possible after an error. While the
+                        target that failed, and those that depend on it,
+                        cannot be remade, the other dependencies of these
+                        targets can be processed all the same.
+  -f, --force           force run of specified cmd, regardless of stamp status
+  -i, --interactive     drop into the interactive mode also called the BitBake
+                        shell.
+  -c CMD, --cmd=CMD     Specify task to execute. Note that this only executes
+                        the specified task for the providee and the packages
+                        it depends on, i.e. 'compile' does not implicitly call
+                        stage for the dependencies (IOW: use only if you know
+                        what you are doing). Depending on the base.bbclass a
+                        listtasks task is defined and will show available
+                        tasks
+  -r FILE, --read=FILE  read the specified file before bitbake.conf
+  -v, --verbose         output more chit-chat to the terminal
+  -D, --debug           Increase the debug level. You can specify this more
+                        than once.
+  -n, --dry-run         don't execute, just go through the motions
+  -p, --parse-only      quit after parsing the BB files (developers only)
+  -d, --disable-psyco   disable using the psyco just-in-time compiler (not
+                        recommended)
+  -s, --show-versions   show current and preferred versions of all packages
+  -e, --environment     show the global or per-package environment (this is
+                        what used to be bbread)
+  -g, --graphviz        emit the dependency trees of the specified packages in
+                        the dot syntax
+  -I IGNORED_DOT_DEPS, --ignore-deps=IGNORED_DOT_DEPS
+                        Stop processing at the given list of dependencies when
+                        generating dependency graphs. This can help to make

+                    <para>There are a number of additional complexities introduced when one wants to manage multiple .bb files.  Clearly there needs to be a way to tell bitbake what files are available, and of those, which we want to execute at this time.  There also needs to be a way for each .bb to express its dependencies, both for build time and runtime.  There must be a way for the user to express their preferences when multiple .bb's provide the same functionality, or when there are multiple versions of a .bb.</para>
+                    <para>The next section, Metadata, outlines how one goes about specifying such things.</para>
+                    <para>Note that the bitbake command, when not using --buildfile, accepts a <varname>PROVIDER</varname>, not a filename or anything else.  By default, a .bb generally PROVIDES its packagename, packagename-version, and packagename-version-revision.</para>

+to images using the <application>dot</application> application from <ulink url="http://www.graphviz.org">graphviz</ulink>. 
+Two files will be written into the current working directory, <emphasis>depends.dot</emphasis> containing dependency information at the package level and <emphasis>task-depends.dot</emphasis> containing a breakdown of the dependencies at the task level. To stop depending on common depends one can use the <prompt>-I depend</prompt> to omit these from the graph. This can lead to more readable graphs. E.g. this way <varname>DEPENDS</varname> from inherited classes, e.g. base.bbclass, can be removed from the graph.</para>

+                <title>Metadata</title>
+                <para>As you may have seen in the usage information, or in the information about .bb files, the BBFILES variable is how the bitbake tool locates its files.  This variable is a space separated list of files that are available, and supports wildcards.
+                <example>
+                    <title>Setting BBFILES</title>
+                    <programlisting><varname>BBFILES</varname> = "/path/to/bbfiles/*.bb"</programlisting>
+                </example></para>
+                <para>With regard to dependencies, it expects the .bb to define a <varname>DEPENDS</varname> variable, which contains a space separated list of <quote>package names</quote>, which themselves are the <varname>PN</varname> variable.  The <varname>PN</varname> variable is, in general, by default, set to a component of the .bb filename.</para>
+                <example>
+                    <title>Depending on another .bb</title>
+                    <para>a.bb:

+                    <title>Using PROVIDES</title>
+                    <para>This example shows the usage of the PROVIDES variable, which allows a given .bb to specify what functionality it provides.</para>
+                    <para>package1.bb:
+    <screen>PROVIDES += "virtual/package"</screen>
+                    </para>

+                    </para>
+                    <para>As you can see, here there are two different .bb's that provide the same functionality (virtual/package).  Clearly, there needs to be a way for the person running bitbake to control which of those providers gets used.  There is, indeed, such a way.</para>
+                    <para>The following would go into a .conf file, to select package1:
+    <screen>PREFERRED_PROVIDER_virtual/package = "package1"</screen>
+                    </para>
+                </example>
+                <example>
+                    <title>Specifying version preference</title>
+                    <para>When there are multiple <quote>versions</quote> of a given package, bitbake defaults to selecting the most recent version, unless otherwise specified.  If the .bb in question has a <varname>DEFAULT_PREFERENCE</varname> set lower than the other .bb's (default is 0), then it will not be selected.  This allows the person or persons maintaining the repository of .bb files to specify their preferences for the default selected version.  In addition, the user can specify their preferences with regard to version.</para>
+                    <para>If the first .bb is named <filename>a_1.1.bb</filename>, then the <varname>PN</varname> variable will be set to <quote>a</quote>, and the <varname>PV</varname> variable will be set to 1.1.</para>
+                    <para>If we then have an <filename>a_1.2.bb</filename>, bitbake will choose 1.2 by default.  However, if we define the following variable in a .conf that bitbake parses, we can change that.
+    <screen>PREFERRED_VERSION_a = "1.1"</screen>
+                    </para>

+                    <para>bbfile collections exist to allow the user to have multiple repositories of bbfiles that contain the same exact package.  For example, one could easily use them to make one's own local copy of an upstream repository, but with custom modifications that one does not want upstream.  Usage:</para>
+                    <screen>BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"
+BBFILE_COLLECTIONS = "upstream local"
+BBFILE_PATTERN_upstream = "^/stuff/openembedded/"

+BBFILE_PRIORITY_upstream = "5"

-# Basically pickle, in python 2.7.3 at least, does badly with data duplication 
-# upon pickling and unpickling. Combine this with duplicate objects and things
-# are a mess.
-#
-# When the sets are originally created, python calls intern() on the set keys
-# which significantly improves memory usage. Sadly the pickle/unpickle process
-# doesn't call intern() on the keys and results in the same strings being duplicated
-# in memory. This also means pickle will save the same string multiple times in
-# the cache file.
-#
-# By having shell and python cacheline objects with setstate/getstate, we force
-# the object creation through our own routine where we can call intern (via internSet).
-#
-# We also use hashable frozensets and ensure we use references to these so that
-# duplicates can be removed, both in memory and in the resulting pickled data.
-#
-# By playing these games, the size of the cache file shrinks dramatically
-# meaning faster load times and the reloaded cache files also consume much less
-# memory. Smaller cache files, faster load times and lower memory usage is good.
-#
-# A custom getstate/setstate using tuples is actually worth 15% cachesize by

-BitBake 'Fetch' clearcase implementation
-
-The clearcase fetcher is used to retrieve files from a ClearCase repository.
-
-Usage in the recipe:
-
-    SRC_URI = "ccrc://cc.example.org/ccrc;vob=/example_vob;module=/example_module"
-    SRCREV = "EXAMPLE_CLEARCASE_TAG"
-    PV = "${@d.getVar("SRCREV", False).replace("/", "+")}"
-
-The fetcher uses the rcleartool or cleartool remote client, depending on which one is available.
-
-Supported SRC_URI options are:
-
- vob
-    (required) The name of the clearcase VOB (with prepending "/")
-
- module
-    The module in the selected VOB (with prepending "/")
-
-    The module and vob parameters are combined to create
-    the following load rule in the view config spec:
-                load <vob><module>
-
- proto
-    http or https
-
-Related variables:
-
-    CCASE_CUSTOM_CONFIG_SPEC
-            Write a config spec to this variable in your recipe to use it instead
-            of the default config spec generated by this fetcher.
-            Please note that the SRCREV loses its functionality if you specify
-            this variable. SRCREV is still used to label the archive after a fetch,
-            but it doesn't define what's fetched.
-
-User credentials:
-    cleartool:
-            The login of cleartool is handled by the system. No special steps needed.
-
-    rcleartool:
-            In order to use rcleartool with authenticated users an `rcleartool login` is
-            necessary before using the fetcher.

-BitBake 'Fetch' git implementation
-
-git fetcher support the SRC_URI with format of:
-SRC_URI = "git://some.host/somepath;OptionA=xxx;OptionB=xxx;..."
-
-Supported SRC_URI options are:
-
- branch
-   The git branch to retrieve from. The default is "master"
-
-   This option also supports multiple branch fetching, with branches
-   separated by commas.  In multiple branches case, the name option
-   must have the same number of names to match the branches, which is
-   used to specify the SRC_REV for the branch
-   e.g:
-   SRC_URI="git://some.host/somepath;branch=branchX,branchY;name=nameX,nameY"
-   SRCREV_nameX = "xxxxxxxxxxxxxxxxxxxx"
-   SRCREV_nameY = "YYYYYYYYYYYYYYYYYYYY"
-
- tag
-    The git tag to retrieve. The default is "master"
-
- protocol
-   The method to use to access the repository. Common options are "git",
-   "http", "https", "file", "ssh" and "rsync". The default is "git".
-
- rebaseable
-   rebaseable indicates that the upstream git repo may rebase in the future,
-   and current revision may disappear from upstream repo. This option will
-   remind fetcher to preserve local cache carefully for future use.
-   The default value is "0", set rebaseable=1 for rebaseable git repo.
-
- nocheckout
-   Don't checkout source code when unpacking. set this option for the recipe
-   who has its own routine to checkout code.
-   The default is "0", set nocheckout=1 if needed.
-
- bareclone
-   Create a bare clone of the source code and don't checkout the source code
-   when unpacking. Set this option for the recipe who has its own routine to
-   checkout code and tracking branch requirements.
-   The default is "0", set bareclone=1 if needed.
-
- nobranch
-   Don't check the SHA validation for branch. set this option for the recipe
-   referring to commit which is valid in tag instead of branch.
-   The default is "0", set nobranch=1 if needed.

-BitBake 'Fetch' NPM implementation
-
-The NPM fetcher is used to retrieve files from the npmjs repository
-
-Usage in the recipe:
-
-    SRC_URI = "npm://registry.npmjs.org/;name=${PN};version=${PV}"
-    Suported SRC_URI options are:
-
-    - name
-    - version
-
-    npm://registry.npmjs.org/${PN}/-/${PN}-${PV}.tgz  would become npm://registry.npmjs.org;name=${PN};ver=${PV}
-    The fetcher all triggers off the existence of ud.localpath. If that exists and has the ".done" stamp, its assumed the fetch is good/done

-BitBake SFTP Fetch implementation
-
-Class for fetching files via SFTP. It tries to adhere to the (now
-expired) IETF Internet Draft for "Uniform Resource Identifier (URI)
-Scheme for Secure File Transfer Protocol (SFTP) and Secure Shell
-(SSH)" (SECSH URI).
-
-It uses SFTP (as to adhere to the SECSH URI specification). It only
-supports key based authentication, not password. This class, unlike
-the SSH fetcher, does not support fetching a directory tree from the
-remote.
-
-  http://tools.ietf.org/html/draft-ietf-secsh-scp-sftp-ssh-uri-04
-  https://www.iana.org/assignments/uri-schemes/prov/sftp
-  https://tools.ietf.org/html/draft-ietf-secsh-filexfer-13
-
-Please note that '/' is used as host path seperator, and not ":"
-as you may be used to from the scp/sftp commands. You can use a
-~ (tilde) to specify a path relative to your home directory.
-(The /~user/ syntax, for specyfing a path relative to another
-user's home directory is not supported.) Note that the tilde must
-still follow the host path seperator ("/"). See exampels below.
-
-Example SRC_URIs:
-
-SRC_URI = "sftp://host.example.com/dir/path.file.txt"
-
-A path relative to your home directory.
-
-SRC_URI = "sftp://host.example.com/~/dir/path.file.txt"
-
-You can also specify a username (specyfing password in the
-URI is not supported, use SSH keys to authenticate):
-
-SRC_URI = "sftp://user@host.example.com/dir/path.file.txt"
