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

Get the source code:

git clone --recurse-submodules https://github.com/lucaceresoli/zynqmp-pmufw-builder.git
cd zynqmp-pmufw-builder

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/.
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!
