I've gone through two Xprotolab Plains now in two days. ?They were running OK and then stopped. ?When applying power through the USB port I get a single short red LED flash, then nothing.
I tried grounding pin 1 (square pad) on the six-pad connector on the end of the board to put the processor into reprogram mode, but still I only get the single red flash, not steady red LED on. ?(Cannot find the pinout or number pattern of this connector anywhere in the manual.)
Are these fried?
?
