USB-C Port Not Functioning on Nvidia Jetson Orin Nano Dev Board

Issue Overview

Users of the Nvidia Jetson Orin Nano development board are experiencing problems with the USB-C port not functioning properly. This issue is particularly problematic when attempting to install JetPack using the SDK Manager through Windows Subsystem for Linux (WSL). The USB-C port fails to detect any connected devices, preventing users from proceeding with the installation process. This problem persists even when different cables are used, suggesting a potentially more serious underlying issue.

Possible Causes

1. Hardware Defect: The USB-C port on the Jetson Orin Nano board may be physically damaged or faulty.

2. Driver Issues: Incompatible or outdated drivers in the WSL environment could be preventing proper recognition of the USB-C port.

3. WSL Limitations: The Windows Subsystem for Linux may have limitations in accessing USB devices, particularly for specialized hardware like the Jetson board.

4. Incorrect Installation Method: Attempting to use SDK Manager on WSL for JetPack installation may not be the correct approach for this specific board.

5. Power Supply Problems: Insufficient power delivery through the USB-C port could lead to detection issues.

6. Firmware or BIOS Issues: Outdated or corrupted firmware on the Jetson board might affect USB-C functionality.

Troubleshooting Steps, Solutions & Fixes

1. Verify Hardware Integrity:

   • Inspect the USB-C port for physical damage.
   • Test the port with multiple known-good USB-C cables and devices to rule out cable issues.

2. Update JetPack Directly on the Device:
   Instead of using SDK Manager through WSL, update JetPack directly on the Jetson Orin Nano:

   sudo apt update
   sudo apt install nvidia-jetpack
   

   This method is recommended as SDK Manager on WSL does not install JetPack SDK.

3. Flash L4T OS Using SD Card:
   If you need to flash the entire L4T (Linux for Tegra) operating system:

   • Download the appropriate L4T release for Jetson Orin Nano.
   • Use a tool like Etcher to flash the image onto an SD card.
   • Insert the SD card into the Jetson board and boot from it.

4. Check USB Controller Status:
   On the Jetson board, run:

   lsusb
   dmesg | grep USB
   

   This will show connected USB devices and any USB-related kernel messages.

5. Verify Power Supply:
   Ensure you’re using a power supply that meets the Jetson Orin Nano’s specifications. Inadequate power can cause USB detection issues.

6. Update Firmware and BIOS:
   Check Nvidia’s developer website for any available firmware or BIOS updates for the Jetson Orin Nano.

7. Alternative Installation Methods:
   If USB-C issues persist, consider alternative methods for JetPack installation:

   • Use a network-based installation if supported.
   • Use a different host machine (preferably Linux-based) for the SDK Manager.

8. Contact Nvidia Support:
   If all else fails, reach out to Nvidia’s developer support. Provide them with:

   • Detailed description of the issue
   • Steps you’ve already taken to troubleshoot
   • Output of diagnostic commands (e.g., lsusb, dmesg)

9. Community Resources:
   Check the Nvidia Developer Forums and GitHub repositories for similar issues and community-driven solutions.

Remember, when dealing with development boards like the Jetson Orin Nano, it’s crucial to follow official documentation and use supported methods for software installation and updates. The USB-C port issue might be a symptom of a broader problem, so a systematic approach to troubleshooting is essential.
