Building

Building scraps requires a Rust nightly compiler.

To build use ./x.py build <board>. Boards can be listed with ./x.py listboards. To run on a QEMU emulator, use ./x.py run <board>.

Currently, scraps targets RISC-V and AArch64.

Current list of boards we target:

• riscvirt (RISC-V)
• raspi64 (AArch64)

You can use ./x.py help with no arguments for more help on usage.
