The issue you’re experiencing with the Jetson AGX Orin, where the system restarts and there’s a momentary screen flicker, could be related to several factors. Based on the provided context, here are a few potential causes and comparisons:

  1. Display Configuration and Bring-Up: The Jetson Linux documentation mentions display configuration and bring-up as part of the kernel adaptation process. It’s possible that the display settings are not being properly configured or brought up during the boot process, leading to the screen flicker.

  2. Boot Architecture: The Jetson AGX Orin boot flow involves multiple stages, including the Bootloader, UEFI, and Linux kernel. Any issues during these stages could cause the system to restart and result in a screen flicker.

  3. Kernel Adaptation: The kernel adaptation process for the Jetson AGX Orin involves modifying the kernel to work with the specific hardware. If the kernel adaptation is not done correctly, it could lead to issues like screen flicker.

  4. UEFI Configuration: The miniUEFI configuration for the Jetson AGX Orin is mentioned in the documentation. If the UEFI configuration is not set up correctly, it could cause issues during the boot process, leading to a screen flicker.

  5. Hardware Issues: It’s also possible that the issue is related to hardware problems, such as a faulty display or a loose connection.

To troubleshoot the issue, you can try the following:

  1. Check the boot logs: Analyze the boot logs to see if there are any errors or warnings related to the display or boot process.
  2. Verify the display configuration: Ensure that the display settings are properly configured in the kernel and UEFI.
  3. Try a different display: If possible, try using a different display to see if the issue is specific to the current display.
  4. Update the kernel and UEFI: Make sure that the kernel and UEFI are up-to-date, as newer versions may have fixed issues related to display configuration and boot process.
  5. Consult the documentation: Refer to the Jetson Linux documentation for more information on display configuration, boot architecture, and kernel adaptation.

In comparison to other Jetson models, the Jetson AGX Orin has a unique boot flow and kernel adaptation process. However, the general troubleshooting steps mentioned above can be applied to other Jetson models as well.

In terms of specific issues mentioned in the context, the following might be related to the screen flicker:

  • Issue 4324714: The secondary display connected to Jetson AGX Orin and Jetson Orin NX/Nano shows as connected in the xrandr utility, but gdm is not rendered on the screen. This issue might be related to display configuration and bring-up.
  • Issue 4618846: The CableCreation branded DP-to-HDMI converter does not work as expected with Jetson AGX Orin. This issue might be related to hardware compatibility or display configuration.

However, without more information about the specific issue you’re experiencing, it’s difficult to provide a more detailed comparison.

Hi,

Do you have any error log from dmesg or serial console log when issue occurred?

Thanks

Hi,

What is your bsp version?
We recommend flashing with the latest bsp r36.5 and check whether issue exists.

Thanks
