Building Zephyr Images via bitbake recipes
|
|
==========================================
|
|
|
|
More detailed and up-to-date information can be found here:
|
|
|
|
https://wiki.yoctoproject.org/wiki/TipsAndTricks/BuildingZephyrImages
|
|
|
|
Prerequisites:
|
|
==============
|
|
|
|
This layer depends on:
|
|
Yocto distro (gatesgarth)
|
|
git://git.yoctoproject.org/poky
|
|
Python layer (meta-openembedded/meta-python) (gatesgarth)
|
|
git://git.openembedded.org/meta-openembedded
|
|
|
|
Modify local conf by adding:
|
|
DISTRO="zephyr"
|
|
|
|
Add "meta-openembedded/meta-oe" to BBLAYERS
|
|
Add "meta-openembedded/meta-python" to BBLAYERS
|
|
Add "meta-zephyr" to BBLAYERS
|
|
|
|
Building and Running Zephyr Samples
|
|
===================================
|
|
|
|
You can build Zephyr samples. There are several sample recipes.
|
|
For example, to build the Zephyr "philosophers" sample:
|
|
|
|
$ MACHINE=qemu-x86 bitbake zephyr-philosophers
|
|
|
|
You can then run the created "philosophers" image in qemu:
|
|
|
|
$ runqemu qemu-x86
|
|
|
|
The same sample, for ARM image:
|
|
|
|
$ MACHINE=qemu-cortex-m3 bitbake zephyr-philosophers
|
|
$ runqemu qemu-cortex-m3
|
|
|
|
The same sample, for Nios2 image:
|
|
|
|
$ MACHINE=qemu-nios2 bitbake zephyr-philosophers
|
|
$ runqemu qemu-nios2
|
|
|
|
|
|
Building and Running Zephyr Tests
|
|
=================================
|
|
Presently only toolchains for ARM, x86, IAMCU and Nios2 are supported.
|
|
(For ARM we use CortexM3 toolchain)
|
|
|
|
To run Zephyr Test using Yocto Image Tests, ensure following in local.conf:
|
|
|
|
INHERIT += "testimage"
|
|
|
|
You can build and test an individual existing Zephyr test.
|
|
This is done by appending the actual test name to the "zephyr-kernel-test",
|
|
for example:
|
|
|
|
$ MACHINE=qemu-x86 bitbake zephyr-kernel-test-sleep
|
|
$ MACHINE=qemu-x86 bitbake zephyr-kernel-test-sleep -c testimage
|
|
|
|
You can also build and run all Zephyr existing tests (as listed in the file
|
|
zephyr-kernel-test.inc). For example:
|
|
|
|
$ MACHINE=qemu-x86 bitbake zephyr-kernel-test-all
|
|
$ MACHINE=qemu-x86 bitbake zephyr-kernel-test-all -c testimage
|
|
or
|
|
$ MACHINE=qemu-cortex-m3 bitbake zephyr-kernel-test-all
|
|
$ MACHINE=qemu-cortex-m3 bitbake zephyr-kernel-test-all -c testimage
|
|
or
|
|
$ MACHINE=qemu-nios2 bitbake zephyr-kernel-test-all
|
|
$ MACHINE=qemu-nios2 bitbake zephyr-kernel-test-all -c testimage
|

============
|
|
|
|
Patches for meta-zephyr should be sent to the yocto@lists.yoctoproject.org
|
|
mailing list. See https://lists.yoctoproject.org/g/yocto for subscription
|
|
details and the list archive. Please add [meta-zephyr] to the subject so
|
|
the patches are identifable.
|
|
|
|
Git can be configured to send mails appropriately when using git send-email:
|
|
|
|
$ git config --local sendemail.to yocto@lists.yoctoproject.org
|
