Hey everyone, I aim to power my Jetson Nano when a signal (5V or 12V) input is introduced to the system. There is the same question here (is there a "soft" way of turning the nano on after shutting it down? - #11 by mjhughes) but there is a J50 header in my Jetson Nano instead of a J40 header. How can I do this through GPIO pins?
you should disable auto power-on,
please access Jetson Nano Developer Kit User Guide ,
if you’re having Nano B01 series. you should connect pin-5 and pin-6 to disable auto power-on; then you’ll need to short the other pins, pin-11 and pin-12 to initial the power.
Thank you much. I have one more question. Does this method provide us to send a “sudo shutdown” command to the Jetson Nano or does it suddenly shut the Jetson Nano down? That’s significant because I prefer a soft shutdown method.
it’s hardware key to issue the power-on, if you connect the pin again, it’ll pop-up the power menu on the ubuntu desktop. you may toggle the options to soft shutdown the device.
On command line consider these two commands:
# "-h" for halt. sudo shutdown -h now # "-r" for reboot. sudo shutdown -r now
