Enter and Exit Deep Sleep State using GPIO on Jetson Orin Nano Dev Kit

Dear Community!

I am currently working on a project, where I need to put the Orin Nano onto sleep and wake it up is there is any detection on the Ultrasonic Sensor. I am able to put the system into sleep if there is no detection from the USS through echo mem > /sys/power/state and send a pulse to the power pin from an external microcontroller when USS detects any object.
I want to avoid using the power pin and want to wake the orin nano through GPIO. Can anyone suggest a better alternative?

Hi pallab.maji,

Are you using the devkit or custom board for Orin Nano?
What’s your Jetpack version in use?

It seems you want to configure a GPIO as wake up source.
Please refer to Enabling GPIO as a Wake-Up Source for details.
and also share the full device tree for further check,
