openrigil-firmware

This is the firmware repo for OpenRigil. This includes accelerated crypto implementation and drivers for our peripherals.

Build

First you should build a lateset riscv-gnu-toolchain with rv32imac ARCH and ilp32 ABI.

# get riscv-gnu-toolchain repo then
cd riscv-gnu-toolchain
./configure --with-arch=rv32imac --with-abi=ilp32

After including the built binaries in your PATH, you could

cd openrigil-firmware
mkdir build; cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../riscv32.cmake ..
make -j`nproc`

Now you could find openrigil.hex in the artifacts. Now you should see the guide in openrigil-rtl.
