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 C1104 it should be probe-rs run --chip MSPM0C1104. (use probe-rs chip list to find your chip)
Update Cargo.toml to have the correct embassy-mspm0 feature. For the LP-MSPM0C1104 it should be mspm0c1104dgs20. Look in the Cargo.toml file of the embassy-mspm0 project to find the correct feature flag for your chip.
If your board has a special clock or power configuration, make sure that it is set up appropriately.
If your board has different pin mapping, update any pin numbers or peripherals in the given example code to match your schematic
