MSP430F5418A bootloader problem

Other Parts Discussed in Thread: MSP430F5418, MSP430F5418A

Hello.

Used MSP430F5418 (without 'A' letter) for years, but now tried to use MSP430F5418A. But can't establish BSL connection.

I'm using self-written BSL communication software (for linux). It worked fine for MSP430F5418, but I get no ACK from MSP430F5418A after

sending packets. Looked for differences, but found none.

Is there a difference of BSL behavour of MSP430F5418 and MSP430F5418A ? Tried to change timings for BSL enter sequencse (as noted in SLAU319B p.33) - still dead :(

Thanks.

    Hi,

    the MSP430F5418A (except revision F) has SYS10 bug, while the MSP430F5418 does not:

    Thanks. Yesterday ported my linux bsl software to microcontroller board. It works fine with MSP430F5418, but MSP430F5418A still doesn't answer (tried 2 boards that works correctly with 5418)  :(

    Checked all timings with digital osciloscope - all correct. Low phase is 8 us. MCU gives no answer. No pulses at MCU's TX pin at all.

    F54xx A and none-A are very different.

    Hello!

    Abort  all above answers,I think that the problem of  MSP430F5418A BSL bootloader still isn't solved.Since then I have always used BSL bootloader for MSP430F5418 with the software name "MspFet" that can be updated and  downloaded from http://kurt.on.ufanet.ru/  successfully .Because of  recommanding to repalce MSP430F5418 by MSP430F5418A in new designs,I start to use MSP430F5418A .I can't program MSP430F5418A  with BSL bootloader.Why?Plese help me to solve it.Thanks!!!

    The mentioned problem with the timing is in the MSPs hardcoded boot code of the 64xxA, not in the BSL code, so replacing the BSL cannot fix it. The new BSL might be better than the original one, but if it isn't called by the boot code, it isn't called.
