Creating and building the Petalinux projectEdit

Documentation referenceEdit

• PetaLinux Tools Documentation Reference guide UG1144
• PetaLinux Tools DocumentationCommand Line Reference Guide UG1157

Petalinux environment setupEdit

To reproduce the Petalinux build:

• clone the repository

git clone --recursive git@git.dave.eu:desk-xz-l/petalinux.git -b desk-xz7-l-1.0.1
cd petalinux

• setup the Petalinux environment

source <petalinux installation path>/Xilinx/petalinux/2021.2/settings.sh

• initialize the configuration file

You can use the proper configuration file from the following table:

Config file	Boot
config_bora	uSD and QSPI-NOR
config_borax	uSD and QSPI-NOR
config_boralite	uSD and QSPI-NOR
config_boralite_nand	NAND
config_boralite_nand_usd	uSD with NAND support

In order to select a configuration file use the following command:

cp project-spec/configs/<configuration file> project-spec/configs/config

Update the hardware descriptionEdit

The hardware description comes from the Vivado project. The Vivado project is already cloned into the Petalinux project.

To build the Hardware description file, please look at this page: Creating and building the Vivado project

You can use the following command to update the hardware description:

petalinux-config --get-hw-description vivado/vivado/<path to .xsa>

When applying the hardware description, the standard menuconfig interface will pop up: just save the current configuration to proceed. If the menuconfig interface will not bring up, send the following command:

petalinux-config --get-hw-description vivado/vivado/<path to .xsa> --silentconfig

Run the Petalinux buildEdit

To build petalinux-image-minimal use the following command:

petalinux-build

For building the dave-image-devel target, use the following command:

petalinux-build -c dave-image-devel

For building only the Linux kernel, use the following command

petalinux-build -c kernel

For building only U-Boot use the following command:

petalinux-build -c u-boot

For generating the BOOT.BIN artifact, run the following command:

petalinux-package --boot --u-boot --force

In case of boot from NAND for the BORA Lite SOM, be careful on using the following command:

petalinux-package --boot --u-boot --kernel --offset 0x1080000 --force

SD card imageEdit

To generate the SD card wic image, execute the following command:

petalinux-package --wic --bootfiles "BOOT.BIN boot.scr image.ub"

If you want to use dave-image-devel root file system, run the following command:

petalinux-package --wic --bootfiles "BOOT.BIN boot.scr image.ub" --rootfs-file build/tmp/deploy/images/zynq-generic/dave-image-devel-zynq-generic.tar.gz
