Hi Paul, This is strange, especially since the circuitry hasn't changed. Perhaps, this is a timing issue on the entry sequence or a parity issue? Since this is a different board, it could be running faster than the previous board. Make sure the baud rate is at 9600 (or very close to this), as discussed in the NOTE on page 6 here . Also, keep in mind that the minimum time delay before sending new characters after characters have been received from the MSP430 BSL is 1.2 ms. Regarding the parity bit, it doesn't look like the BSL on the MSP430F5419 expects a parity bit (discussed on page 42 here ), so if you're using even parity for your general UART communication, this could be a problem.
