=== Petalinux build environment setup ===To reproduce the Petalinux build: 
* clone the repository
<syntaxhighlight lang="bash">
git clone --recursive git@git.dave.eu:sdv12desk-xz-l/petalinux.git -b desk-xz7-l-rel-1.0.01

* setup the Petalinux environment
<syntaxhighlight lang="bash">
source /opt<petalinux installation path>/Xilinx/petalinux/2021.2/settings.sh</syntaxhighlight> * initialize the configuration file You can use the proper configuration file from the following table: {| class="wikitable"|-! Config file! Boot|-| <code>config_bora</code>| uSD and QSPI-NOR|-| <code>config_borax</code>| uSD and QSPI-NOR|-| <code>config_boralite</code>| uSD and QSPI-NOR|-| <code>config_boralite_nand</code>| NAND|-| <code>config_boralite_nand_usd</code>| uSD with NAND support|} In order to select a configuration file use the following command: <syntaxhighlight lang="bash">cp project-spec/configs/<configuration file> project-spec/configs/config
</syntaxhighlight>
* update === Update the hardware description (with === The hardware description comes from the Vivado project. The Vivado project is already cloned into the Petalinux project.  To build the one provided as output from Hardware description file, please look at this page: [https://wiki.dave.eu/index.php/DESK-XZ7-L/Development/Creating_and_building_the_Vivado_project Creating and building the Vivado project above)] You can use the following command to update the hardware description:

If the menuconfig interface will not bring up, send the following command: <syntaxhighlight lang="bash">petalinux-config --get-hw-description vivado/vivado/<path to .xsa> --silentconfig</syntaxhighlight> === Run the Petalinux build=== To build <code>petalinux-image-minimal</code> use the following command: 
<syntaxhighlight lang="bash">
petalinux-build
</syntaxhighlight>
 
For building the <code>dave-image-devel</code> target, use the following command:
 
<syntaxhighlight lang="bash">

</syntaxhighlight>
 
For building only U-Boot use the following command:
 
<syntaxhighlight lang="bash">
petalinux-build -c u-boot
