My Jetson Nano seems to power on as the green light comes on with both USB power (5V=2.5A) and DC barrel connector with J48 jumper but is unable to output display to a monitor. I have tried two different monitors with separate cables and am unable to get any display out of the board.
At least try re-flashing the device.
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Then was the re-flash successful?
Is there anything coming out from the serial console now?
