Uses TEST_SERIALCONTROL_CMD to open a serial connection to the target
and execute commands. This is a drop in replacement for the ssh target,
fully supporting the same API. Supported with testexport.
To use, set the following in local.conf:
- TEST_TARGET to "serial"
- TEST_SERIALCONTROL_CMD to a shell command or script which connects to
the serial console of the target and forwards that connection to
standard input/output.
- TEST_SERIALCONTROL_EXTRA_ARGS (optional) any parameters that must be
passed to the serial control command.
- TEST_SERIALCONTROL_PS1 (optional) A regex string representing an empty
prompt on the target terminal. Example: "root@target:.*# ". This is
used to find an empty shell after each command is run. This field is
optional and will default to "root@{MACHINE}:.*# " if no other value is
given.
- TEST_SERIALCONTROL_CONNECT_TIMEOUT (optional) Specifies the timeout in
seconds for the initial connection to the target. Defaults to 10 if no
other value is given.
The serial target does have some additional limitations over the ssh
target.
1. Only supports one "run" command at a time. If two threads attempt to
call "run", one will block until it finishes. This is a limitation of
the serial link, since two connections cannot be opened at once.
2. For file transfer, the target needs a shell and the base32 program.
The file transfer implementation was chosen to be as generic as
possible, so it could support as many targets as possible.
3. Transferring files is significantly slower. On a 115200 baud serial
connection, the fastest observed speed was 30kbps. This is due to
overhead in the implementation due to decisions documented in #2
above.

Tested with core-image-sato on real hardware. TEST_SERIALCONTROL_CMD
was set to a bash script which connected with telnet to the target.
Additionally tested with QEMU by setting TEST_SERIALCONTROL_CMD to
"ssh -o StrictHostKeyChecking=no root@192.168.7.2". This imitates
a serial connection to the QEMU instance.
Steps:
1) Set the following in local.conf:
- IMAGE_CLASSES += "testexport"
- TEST_TARGET = "serial"
- TEST_SERIALCONTROL_CMD="ssh -o StrictHostKeyChecking=no root@192.168.7.2"
2) Build an image
- bitbake core-image-sato
3) Run the test export
- bitbake -c testexport core-image-sato
4) Run the image in qemu
- runqemu nographic core-image-sato
5) Navigate to the test export directory
6) Run the exported tests with target-type set to serial
- ./oe-test runtime --test-data-file ./data/testdata.json --packages-manifest ./data/manifest --debug --target-type serial

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
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 BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

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:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
