you were right! it was stuck on AutoRCM. thank you3. check if console in RCM automatically from cold start.
maybe the same applies for your situation? Since M92 and BQ24 caps showed no short, I just confirmed USB was ok and then tried injecting with TegraRCM.Keep us updated on what you find.
to confirm USB, unplug BATT, plugged in charger, checked BATT leads on board to confirm 4-5v.
