hi
I am working on Jetson TK1 based custom board. I am powering up the board by providing 12V from external power supply. The board is not behaving to the power properly.
Sometimes it gets powered on right after after I provide 12V supply. Sometimes it does not power on automatically but we have to press power on button to power it on.
Strange part is that sometimes it does not even power on by pressing the power on button, then I unplug the supply and short power and GND, Also I press the power button for some time, the I plug the power again and this time the board gets on.
Problem is that when I am working on the board separately, then I can do that but when this board fits in the system, I do not have access to power button.
Can anyone tell me what might be the issue?
