11 years agoI had a development kit that exhibited strange symptoms similar to what you've described.. It turned out to be damage caused by static electricity. We weren't taking proper static precautions and the board was damaged but not inoperable. We had to have it repaired.
The give away was that it also stopped working with the factory created configuration files. See if your board is working with the factory configuration.
