I have a problem with my Jetson Nano Carrier Board. I connect my barrel jack power supply, but jetson doesn’t start. The device powers up fine via uUSB or GPIO header. It is the very first version of the carrier board.
- J48 is in place
- TPS25944L VIN is 5.25V
- TPS25944L VOUT is 0V
- Enable pin of TPS25944L (DC_EN_UVLO) is at 1.2V
- Is it possible that I have a board with a faulty TPS25944L chip? The board worked fine for over a year, but that’s the first time I’m connecting it using the DC jack.
- Perhaps the VIN of 5.25 is tripping the over-voltage protection?
