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 --recurse-submodules 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-xilinx-elf/.

3. Build it:

   ./build.sh pmufw-build
   

   The PMU firmware will be called pmufw.bin in the current directory. Custom compiler flags can be passed in the CFLAGS environment variable, E.G.:

   CFLAGS="-DENABLE_EM" ./build.sh pmufw-build
   

Enjoy!
