Scripts to generate BOOT.BIN images for PyNQ, ZedBoard, ZC706, Ultra96, ZCU102

Automates the following steps

  • download specific revision of u-boot-xlnx
  • build it
  • download specific revision of linux-xlnx kernel
  • build uImage
  • create simple Vivado project with default initialization and constraints
  • export .hdf file
  • use hsi to build FSBL
  • use bootgen to generate boot image BOOT.BIN
  • download PyNQ standard SDcard image as base
  • extract root FS from image, and FSBL/SSBL, devicetree for PyNQ
  • prepare SD device to generate bootable SD (optional)

Usage:

Create a TaPaSCo workspace with the help of tapasco-init.sh in the root of this repository and source the generated tapasco-setup.sh, this will set TAPASCO_HOME. To then generate a boot image simply run:

./generate_boot_image.sh BOARD VERSION [DISK SIZE] [DEVICE]

VERSION refers to the release/tag of the Xilinx Open Source Linux [0] stack.

After writing the image to an SDCard and booting up, install Rust and follow the steps in the top level README to build the tapasco runtime. A reboot might be necessary.

Notes:

  • you might have to add the "noacl" option when mounting the rootfs, depending on distro
  • you can edit the OMIT_ROOT variable in generate_boot_image.sh to OMIT_ROOT=true to only go through the steps that do not require root privileges, this can be useful for checking just the build processes
  • the ZCU102 seems to be very picky about the SDCard used, sometimes it refuses to load larger files and u-boot simply prints "mmc fail to send stop cmd" or similar when loading the Image file
    • if that happens, try editing bootscr/boot-zcu102.txt to load the compressed image Image.gz before re-generating the boot.scr script and make sure to copy Image.gz from linux-xlnx/arch/arm64/boot into the boot section
