Other Parts Discussed in Thread: MSP430F2101Hello: Is there any way to change the bootloader speed/parity settings in the MSP430F2101 to use 9600 N81 ? I think that the bootloader is in the MSP430’s flash. Any feedback or input is appreciated! Thanks! Paul

    My TI FAE checked into this:

    The msp430f2xx series has the BSL in ROM so therefore it is non-changeable. The newer 5xx devices have it in FLASH, so it would be modifiable.

    isn't 9600/8N1 the default BSL setting?

    However, the BSL doe snot provide any UI to change the baudrate at will. It only accepts its default setting on startup, and onyl a few newer BSL incarnations allow switching to a different baudrate (57600/8N1).

    If you want something else right from the start, you'll need to write your own BSL, which is not a trivial job, and is only possible at all on the newest devices with rewritable (flash based)  BSL.
