I just observed that when un- and replugging the 12V DC plug on the board, the Jetson TK1 starts to boot. But when un- and replugging the wall outlet, the Jetson does not boot up until the power button on the board is pressed. But when leaving the wall outlet unplugged for > 1min and then replugging, it comes up again. This is the same for both of our devices.
Is this expected behaviour, and if not, can there be anything done about this?
