I did more testing and I beleive the SXKEY is ok as I can program and debug in my SX28 (PDB) ok. It appears that I can program in my SX52 protoboard too but the programs don't really do anything and if I go into DEBUG mode I always get the ghosted out STEP, WALK, RUN and it says it is sleeping. I probably fried the SX52 somehow. Luckly I bought 2 but the bad thing is that I have many LED ribbon cable wires soldered to RA, RB, RC, RD and RE. Unsoldering this weekend and try it again with the other board.
