See here.

git clone https://code.kercy666.com/Kercy/krcyos.git
# if you prefer github:

# ...

Note that it is supervisor-test.

zig build run
# or:
# only run

Build for real board:

zig build run -Dboard=real_board
# or:
# only real run

Press Ctrl+A + X to exit qemu.

For user-test:

zig build run -Dmode=user
# or:
# only run user

Run unit tests:

No reason. Zig worth.
