Hi,
I have an Arty A7-35T that I bought last year but never really used. I pull it out of the cabinet today and use for the my next project. However, when I plug the usb to it, no LED on at all including the power LED. I also see neither overheat or anything concerning. I measure the VCC and GND (labeled in the connector) and read out 0V. I unplug the device and see that the external power jack and short circuit (all three pins) are shorted, though I never used the external source. Again, no visible smoke or overheat on any chips are found.
I bought it roughly a year ago (potentially less than a year), I never tested the board when I received it. It was meant for one project that was never started, so I just sit in my cabinet. Could someone advise what the debugging process should be?
Thanks,
Tony Nguyen
