Re: Is our Jetson TK1 Broken?
https://devtalk.nvidia.com/default/t...fails-to-boot/
---This is if the board has lost the bootstrap loader, but it sounds more serious than that.
Try the board with nothing but power from the ac adapter. If that doesn't work, check to see if you are getting 12v from the ac adapter. The Tk-1 should run off 12v battery, but may not if the voltage is +- 2v of 12.
Did the board ever work, or did something happen when it was connected to something else? Since you have supplied very few details, it is hard to say what 's going on.
If the board turns on briefly and then shuts down, it is usually a power or hardware issue, but not always. Check to see if something is getting shorted out, (aluminum chips on the board, pins or jumpers messed up, etc)
All in all, I'd put this issue on the back burner until you have a bagged robot.
