LPC 1769 RevB, LPC Expresso v8.2.2 Build 650, Semihosted C
I have run the code below out to the 1769 using the attached programmer. It worked once and then I could step into the code therafter, but the LED never lit again. This example doesn't actually, blink, but should turn on the red LED. I took the board to a friend, and he was able to get my blinky blinking using the LPC-Link2 programmer, so I bought one and it also is able to program the part and step into the code, but does not blink the light. I tried to program the flash with mass erase and the ISPResetConnect.scp file which had no apparent effect on the problem. I now have 4 boards with this issue, since I thought that I was damaging them until my friend's setup was able to revive them. I also tried using the USB cable direct to the PC and to a different PC. I am unable to find any references to this issue, since most of the reset type questions involve not being able to debug. I have always been able to program and debug these parts. Something is keeping the IO from working.
