Does NVIDIA Orin AGX board support suspend/resume feature

I burned Jetpack 6.2 Linux 36.4.3 Image into NVIDIA Orin AGX board , after it boots up, I use below command to test suspend/resume, but failed.

echo +10 > /sys/class/rtc/rtc0/wakealarm
echo mem > /sys/power/state

after board wakes up, there is nothing displayed on the monitor.

Could you please tell me how to verify the suspend/resume feature on NVIDIA Orin AGX board?

thanks,

To verify the suspend/resume feature on the NVIDIA Orin AGX board, you can follow these steps:

  1. Check the kernel version: Ensure that you are running the correct kernel version, which is Linux 36.4.3, as mentioned in your question.
  2. Verify the suspend/resume command: The command you used, echo +10 > /sys/class/rtc/rtc0/wakealarm followed by echo mem > /sys/power/state, is correct. This command sets the wake-up alarm to 10 seconds in the future and then suspends the system to memory.
  3. Check the system logs: After the system wakes up, check the system logs to see if there are any error messages related to the suspend/resume process. You can use the dmesg command to view the kernel logs.
  4. Verify the display settings: Since you mentioned that there is nothing displayed on the monitor after waking up, check the display settings to ensure that the HDMI output is enabled and configured correctly. You can use the xrandr command to verify the display settings.
  5. Try a different suspend method: Instead of using the echo mem > /sys/power/state command, try using the sudo systemctl suspend command to suspend the system. This command uses the systemd suspend mechanism, which might work differently than the manual suspend method.
  6. Check the power management settings: Ensure that the power management settings are configured correctly. You can check the /sys/power directory to see if the power management settings are enabled.
  7. Compare with other boards: If you have access to other NVIDIA Orin AGX boards, try testing the suspend/resume feature on those boards to see if the issue is specific to your board or if it’s a general issue with the Jetpack 6.2 Linux 36.4.3 image.

In comparison to other boards, the NVIDIA Orin AGX board has specific power management requirements, and the suspend/resume feature might need to be configured differently. For example, on the Jetson Xavier NX board, the suspend/resume feature requires specific settings in the device tree and kernel configuration.

Additionally, you can try searching for similar issues on the NVIDIA forums or online communities, such as the NVIDIA Developer Forums or the Linux kernel mailing list, to see if others have encountered similar problems and found solutions.

If none of these steps resolve the issue, you may want to consider seeking further assistance from NVIDIA support or a Linux kernel expert.

HI Nvidia tech support,

If you still reply ticket with AI, I will report this issue to up level.

Hi,

The AI reply is just an initial reply. We still have real people to reply your topic one by one but need to take more time.

There is a known issue in display resume and suspend. This will be fixed in rel-36.5.x release.

The problem here should be “no display after resume/suspend” but not the system itself. The system supports resume/suspend in every Jetapck version.

I try some times, I also have seen the case that there is only a back ground on screen, and there is no icon and other things on the screen. Even if run es2gears_x11 command, there is no gears displayed on the screen.

thanks,
