2. Use `nightly-2024-03-22` toolchain.
2. Run `cargo build` to build the firmware. 2. Run `cargo build --release` to build the firmware (debug builds won't work for now).
3. Run `RAVEDUDE_PORT=/dev/ttyUSB0 cargo run --release` to flash the firmware to a connected board. If `ravedude` fails to detect your board, check its documentation at
