Hello,

  1. Fault Model & Application: Jetson Orin Nano 8GB SOM; Application: Logistics robot; the issue occurs in batch units.

  2. Fault Occurrence Cycle: Devices work normally initially; mass failures start to appear after approximately 9 months of continuous operation. Re-flashing the firmware can resolve the issue temporarily.

  3. Visible Failure Symptoms

  • No NVIDIA boot logo on power-on; the screen remains completely black throughout startup.

  • External USB keyboard is unresponsive (the keyboard indicator lights up via number toggle keys on normal devices); no interactive operation is possible.

  1. Eliminated Suspected Causes
  • Abnormal sudden power loss is ruled out: Our custom device adopts long-press button shutdown, strictly following the official developer board design without forced power cut. By comparison, direct plug/unplug power interruption on official reference boards does not cause the same long-term failure.

  1. Temporary Solution: The system can only be restored by re-flashing the SOM firmware.

  2. Attachment: Boot logs of faulty and normal Orin Nano SOM are attached for comparison.

  • Flashing Environment: NVIDIA SDK Manager 2.2.0, JetPack 5.1.3 selected; Target hardware: Jetson Orin Nano 8GB SOM; Host PC: Ubuntu 20.04 x86_64

  • Flashing Process: Repeated USB disconnect/connect prompts for APX mode appear during flashing (prompt: NVIDIA USB Device was removed (APX) / was added). However, the final process shows INSTALLATION COMPLETED SUCCESSFULLY, indicating the flashing procedure finished successfully.
