PEX_WAKE_N no Function

JP6.1 customized board AGX Orin

I set the AGX Orin to suspend mode (“sudo systemctl suspend”), and I manually set the PEX_WAKE_N pin to low/high to wake up AGX Orin, but is not works. Orin still sleep

here is the PEX_WAKE_N pinmux config

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

It doesn’t do anything

Hi,
The pin is one pin in M.2 PCIe interface. Do you use it as a single GPIO pin? Or trigger the event through a PCIe device?

I use it as a single GPIO pin, I set the pin as input, used the oscilloscope to measure the pin level to high, then grounded the pin, measured it to low, and returned it to high, but the system did not wake up

Hi,
Please check the section:

Jetson AGX Orin Platform Adaptation and Bring-Up — NVIDIA Jetson Linux Developer Guide

And make sure you add the pin to pmc.c
