View source for CL-SOM-iMX8X: Yocto Linux: Building images

= Overview =
The Yocto Project is an open-source collaboration focused on embedded Linux development.<br>
The purpose of this article is to show how to get Yocto Image with support for the CL-SOM-iMX8X System-on-Module.

= Yocto Environment Setup =
Yocto host requirements are listed on the [https://www.yoctoproject.org/docs/2.6/brief-yoctoprojectqs/brief-yoctoprojectqs.html#brief-build-system-packages official Yocto website]

In order to setup the NXP Yocto BSP build environment please issue the following commands. More detailed instructions can be found in the [https://source.codeaurora.org/external/imx/meta-fsl-bsp-release/tree/imx/README?h=sumo-4.14.98-2.0.0_ga NXP readme file]
<pre>repo init -u git://source.codeaurora.org/external/imx/imx-manifest.git -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml
repo sync
</pre>
The next step is getting the CL-SOM-iMX8X8 meta-layer.
<pre>git clone -b r1.0 https://github.com/compulab-yokneam/meta-cl-som-imx8x.git sources/meta-compulab-bsp/meta-cl-som-imx8x</pre>
The CL-SOM-iMX8X8 meta-layer contains recipes adjustments and configuration files for the CL-SOM-iMX8X module.

= Building the Image =
This section provides information about building the CL-SOM-iMX8X module images.

==Create Build Environment==
* Issue the '''Compulab''' Setup Script:
<pre>source sources/meta-compulab-bsp/meta-cl-som-imx8x/tools/setup-cl-som-imx8x-env -b build-xwayland</pre>

== Building the images ==
The Yocto Project build uses the {{parameter|bitbake}} command.

* To build a Compulab image with GUI use the command below:
<pre>bitbake -k cl-som-imx8x-eval</pre>
* To build a minimal Linux image use the command below:
<pre>bitbake -k core-image-full-cmdline</pre>

* To re-build only the Linux kernel use the command below:
<pre>source setup-environment build-xwayland
bitbake -c cleansstate linux-imx
bitbake -k linux-imx
</pre>
* To re-build only the u-boot bootloader and boot image use the command below:
<pre>source setup-environment build-xwayland
bitbake -c cleansstate imx-boot u-boot-imx
bitbake -k imx-boot u-boot-imx
</pre>
