Hi Friends!

I have a problem with the Flash of my MSP430 FET.
I think I erased the Flash. I launched a test program
from Texas Industries with the name Flash_Write.c.
Now it is damaged. If I will debug a new programm,
there is an error in C-Spy. It's a target error:
Erase check error at adress 0x1000. I think it is unable to
erase the Flash memory. What did I do wrong? 
What can I do?

With best regards
David

I could not solute the problem. The program from TI
loops endless. I think, that is the problem.
I don't know a solution for this problem.
Is there theoretically a solution for this?
Or is it damaged forever?
