Other Parts Discussed in Thread: MSP430F2619, MSP430-FLASHER

Hi

I have some data which is save on Flash memory of MSP430F2619 say 0xF000, when I do firmware updating,

can I keep this data untouched. I couldn't find any options to keep segments of data when I was using Flasher.

Any input are welcome.

Thanks

    Hi Lynn,

    It sounds like there is some certain data that you want to retain when programming your device. If the data is in a segment, and there is no other data in the segment, then I think you could use -eERASE_SEGMENT to only erase the other segments and leave that segment untouched before programming - I'd have to do some experimenting with it though. That is where I would start your investigation if I were you.

    One other way might be to use multiple runs of the MSP430-Flasher - run it once where all you do is read out the data you are trying to retain, then run it again to program in most of your code, and run a third time to restore the data you were retaining. Or you could merge the data you read out into your code file maybe.

    Hope this gives you some ideas to try.

    Regards,

    Katie
