Greetngs,
I had similiar same problem with the F1232 and thought I must have blown
up the chip, although static electricity is not a problem in Seattle.
After the second one `blew' and I hadn't even touched the board, I could
see that the processor was still running the code which had been
previously loaded.
Thinking I'd poke around using gdb I fired up gdb-proxy which connected to
the chip, and I was able to run gdb. Then I tried an erase command and it
worked, and after that I could load programs again via jtag. I repeated
on the first `blown' processor and it also worked.
If this fixes your problem then some kind of bug report should probably be
filed.
Sincerely,
David Smead

It is definitely the right chip for the build.
I had successfully downloaded elf files, made a minor change to my program and
tried to download the new elf file and received the error message.

Are you sure you have the right chip on the board, and the right chip
selected for the build? Most of the time when I get this sort of error it's
because I've built the code for an '149 but the card has an '147, or
similar.
Other than that, I've sometimes seen msp430 chips die, and fail to
communicate on the jtag port. Sometimes the chip still runs fine, but I
can't program it or otherwise access the jtag (reseting does not need jtag
communication). The only solution I've found is using a new chip.

I am working on an MSP430F169 board and have successfully programmed
it with the Olimex parallel port JTAG cable and pyJTAG until now.
When I run the command msp430-jtag -eEpvr app.elf
I get the error
An error occoured:
Could not write target memory
I am able to reset the MSP430F169 using msp430-jtag -r
performing just an erase with msp430-jtag -e
produces the same error message.
Powering down the MSP430F169 did not help.
Any ideas on how to determine what is wrong with the JTAG flash
programming would be appreciated.
Thanks.
