I think I have a partly damaged MSP430F149.

However, this MSP430 is fully programmable with the IAR tools (FET_R420.exe).
Version 1 (FET_R308.exe FET_R308u.exe) fails too.
If I exchange the MSP430F149 with another one (same charge) it works
with gdbproxy and no errors.
(I tested with Win XP and win95, MSP-FET, the voltage is 3.3 volts
externally applied, on both machines I got the same results).
I wonder what happend with my '149, and why the IAR tools (V2) are better.
It seems that the FLASH could not be erased properly. How can I erase the
FLASH with insight? (only erasing, not writing, I want to play with flash
erasing to see how often I have to issue the erase command). With the
memory tool I can only reset bits (=0) in the flash, setting (=1) is not
possible.

You always have to erase the flash manually when using gdbproxy. The
following GDB commands will erase the relevant sections of flash:
monitor erase all
monitor erase main
monitor erase info
