zynqmp-pmufw-builder

This is a simple script to build a PMU firmware for the Xilinx ZynqMP System-on-Chip.

It design goals are to:

  • be simple to use: just type a few commands to have a PMU firmware ready
  • be easy to understand and modify to your needs
  • have minimal dependencies: only crosstool-NG and the PMU firmware source code are needed

Usage

  1. Get the source code:

    git clone --recursive https://github.com/lucaceresoli/zynqmp-pmufw-builder.git
    cd zynqmp-pmufw-builder
    
  2. Generate a suitable microblaze toolchain (this is normally needed only once):

    ./build.sh toolchain
    

    At the end a toolchain will be available in ~/x-tools/microblazeel-unknown-elf/.

  3. Optionally you can overwrite pm_cfg_obj.c with the configuration object for your design.

  4. Then patch the PMUFW sources so it loads a hard-coded configuraton object from pm_cfg_obj.c:

    ./build.sh pmufw-patch
    
  5. Build it:

    ./build.sh pmufw-build
    

    The PMU firmware will be called pmufw.bin in the current directory.

Enjoy!
