Getting Started

Clone the toy

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

Simply run it

zig build run
# or:
# only run qemu

If you have a real board:

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

Then flash to your board.

Press Ctrl+A + X to exit qemu.

What's more

Try another log level:

zig build run -Dlog=debug
# or:
# only run qemu debug

Run unit tests:

zig build test
# or:
# only test

That's it.

Why not C/Rust?

No reason. Zig worth.
