Hi, I have a Jetson Nano and I want to power it from the J41 connector (expansion header) using a 5V/5A power supply (laboratory power supply). The connections are correct, in fact I can turn on and work with the Jetson without problems, but if I turn off the power supply and turn it back on after a few seconds, the Jetson does not turn on anymore (in fact, the power supply tells me that the load is less than 100mA). If I turn off the power supply and turn it back on after 10-15 minutes, the Jetson works perfectly. I have tried with other power supplies and I get the same result. However, if I try to power the Jetson from the Micro-USB port, the Jetson turns on and off without problems.
PS: Jumper J48 is open, not shorted. The board was powered without modifying jumpers or anything, I just connected the 5V and GND pins to the power supply.
PS2: if i disable the auto-on with a jumper on “AUTO ON” (J40), and i turn on the jetson with a button, the jetson work perfectly! so, if i turn off the power supply i’m not forced to wait 10-15 minutes to turn it on another time.
