 You might need to adjust `.cargo/config.toml`, `Cargo.toml` and possibly update pin numbers or peripherals to match the specific MCU or board you are using.
 
 * [ ] Update .cargo/config.toml with the correct probe-rs command to use your specific MCU. For example for L1306 it should be `probe-rs run --chip MSPM0L1306`. (use `probe-rs chip list` to find your chip)
