===How to build the Yocto BSP images including the U-Boot binary file, the Linux kernel image, and the target root file system imagewith KAS===

Before running the build, the KAS environment must be initialized properly. [[DESK-MX8M-L | DESK-MX8M-L]] Yocto BSP uses [https://code.google.com/p/git-repo/ git-repo] tool to fetch all the required git repositories. To install it, please use the following commands:

then, fetch the Yocto <code>meta-desk-mx</code> repositories with the proper branch:

(venv) dvdk@vagrant:~/desk-mx-l/yocto$ ./repo init -u git clone git@git.dave.eu:desk-mx-l/meta-desk-mx-l-bsp.git -b refs/tags/desk-mx8m-l-4.01.0dvdk@vagrant:~/desk-mx-l/yocto$ ./repo sync -c

In case ==== Running the build ==== Please note that even the basic root file system requires a few hours to build on a mid/hi range desktop (4-6 cores, 8-12 GiB RAM) also depending on your Internet connection speed (all sources are fetched from the network). Nearly 20GiB of disk space is required for the build. The process may be slowed down significantly since the performances of a virtual machine are reduced if compared to the physical hardware. Thus, it's recommended to check the hardware capabilities of the host system and, when building with Yocto is required, to consider the following options: * Migrating the build system to a physical machine* Assuming that the host system has the required resources, extending the hardware capabilities of the default MVM (e.g. adding more cores and disk space). Once completed the initialization phase, developers can launch the Yocto image build with KAS, with the following commands: * for build <code>cadave-certificatesimage-devel</code> failures, which may appears during https access to some repo:image with <code>DESK-MX8MM-L</code> machine

==== Initialize DISTRO and MACHINE ====Select Where <code>dave-image-devel</code> is one of the Weston backend (you will be asked to accept the EULA):images listed in [[#Quick reference|here]].

==== Running Generating the build SDKs====

Please note that even the basic root file system requires a few hours In way to build on a mid/hi range desktop (4-6 cores, 8-12 GiB RAM) also depending on your Internet connection speed (all sources are fetched from get the network). Nearly 20GiB of disk space is required corresponding SDK for the build. The process may be slowed down significantly since the performances of a virtual machine are reduced if compared to the physical hardware. ThusQT6, it's recommended to check the hardware capabilities of the host system and, when building with Yocto is required, to consider perform the following optionscommand: * Migrating the build system to a physical machine* Assuming that the host system has the required resources, extending the hardware capabilities of the default MVM (e.g. adding more cores and disk space).

(venv) dvdk@vagrant:~/desk-mx-l/yocto/$ kas builddesk-wayland$ bitbake dave-imagemx8mm-devell_qt6_sdk.yml

====Generating the SDKs==== After creating an image as described in the previous version, the corresponding SDK can be generated by issuing the following command:* for <code>DESK-MX8MP-L</code> machine

bitbake dave(venv) dvdk@vagrant:~/desk-imagemx-devel l/yocto$ kas build desk-c populatemx8mp-sdkl_qt6_sdk.yml

bitbake meta(venv) dvdk@vagrant:~/desk-toolchainmx-l/yocto$ kas build desk-mx8mm-l_toolchain.yml

==== Building additional packages ==== To build additional packages the user must select the ''DISTRO'' and source the * for <code>deskDESK-setupMX8MP-release.shL</code> scriptmachine

(venv) dvdk@vagrant:~/desk-mx-l/yocto$ DISTRO=fsl-imx-wayland MACHINE=kas build desk-mx8mp source desk-setup-releasel_toolchain.sh -b build-waylanddvdk@vagrant:~/desk-mx-l/yocto/build-wayland$yml

And then can run any of ==== Building additional packages ==== To build additional packages, for example <code>memtester</code> the user need to perform the [http://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#usingpoky-components-bitbake bitbake] following command.

(venv) dvdk@vagrant:~/desk-mx-l/yocto/$ KAS_TARGET="memtester" kas builddesk-wayland$ bitbake memtestermx8mm-l_devel.yml

The resulting packages (the default format is rpmdeb) can be found inside <code>build/tmp/deploy/rpmdeb</code>.
