Long way to build the panda image

If you are interested in the main way to build, go to Building the panda image, the current document was done mainly for learning purposes.

The following steps might need to be run in a docker container(possibly kas image), if the dependencies are not available in your system.

• Use repo tool to initialise the yocto sources based on Xilinx’s yocto manifest, this will automatically add layers like meta-xilinx and meta-petalinux:

  BRANCH="rel-v2023.2"
  repo init -u https://gitenterprise.xilinx.com/Yocto/yocto-manifests.git -b $BRANCH
  

• Load development environment passing the build directory as argument:

  . setupsdk build
  

• Add layer meta-panda to you yocto build:

  git clone https://github.com/PandABlocks/meta-panda ../sources/meta-panda
  bitbake-layers add-layer ../sources/meta-panda
  

• Set the following variables in conf/local.conf:

  • MACHINE="pandabox" or MACHINE="xu5-s1"

  • DISTRO="panda-petalinux"

• Build panda-image by running: bitbake panda-image

• Gather the output files from the deploy folder:

  mkdir boot
  cp -Lf tmp/deploy/images/pandabox/fitImage-petalinux-initramfs-image-pandabox-pandabox boot/image.ub
  cp -f tmp/deploy/images/pandabox/{rootfs.squashfs,boot.bin,boot.scr,target-defs} boot/
  zip boot-pandabox.zip boot/*
