EMBARK: An Educational and Modifiable BAsic RISC-V Kernel

EMBARK is a small kernel, designed for educational projects. It has very limited scope and is designed to be extensible.

The toolchain:

I am using the riscv-gnu-toolchain, configured with --with-arch=rv32im --disable-linux --disable-gdb --disable-multilib and built using make -j <number of threads>.

The Makefile:

You can build the kernel using make kernel. Make sure the toolchain is in your path!
