MSP430F5259: Trouble writing memory block

Part Number: MSP430F5259
Other Parts Discussed in Thread: MSP-FET

Trouble writing memory block!    My life was pretty good until this started to happen.  It seems like a hardware issue, because without every changing my code I can get the emulator attached if I spend enough time rebooting, and unplugging the emulator and restarting the target and things like that, and then suddenly the emulator will attach.  I have tried different MS-FET and different target boards, and they are all suffering from this issue.

    Hi Tom,

    To clarify, this issue only occurs some of the time and nothing was changed before it started occurring? Do the MSP-FETs work with other devices/is the issue occurring with all target boards?

    Hi Amruta.   The problem seems to have come out of nowhere.    I added quite a bit more code, but when I remove that code the problem does not go away.  

        I have two MS-FET, and I have several target boards.  I also have more than one laptop.  I just reloaded Code Composer on both machines.  I got the emulator running for a while, but then I changed the code and tried to attach the emulator again, and sure enough it won't load.

       The problem is not consistent.  Sometimes I can attach after I reboot the laptop for instance.

      Sometimes after I clean the project, then the emulator will attach.

    I just got the emulator to attach again by cycling power on the target.  I never used to have to do this kind of thing.

    Hi Tom,

    Are you plugging into a high speed USB port on your laptop?

    Yes, I have tried that.  Using two different laptops, two different MSP-FET, different cables, different targets.  This is very confusing.   I un-installed and re-installed CCS on both laptops.

    Hi Tom,

    To double check, are you plugging into a high speed USB port? Some laptops with these ports have had an issue with the MSP-FET in the past.
