TC358743 on Orin Nano Devkit

Issue Overview

Users are experiencing difficulties with the Nvidia Jetson Orin Nano Dev Kit when attempting to interface it with a TC358743 adapter. The primary symptom reported is the inability to configure the device tree to recognize the TC358743 on the CAM0 port. This issue arises while using JetPack version 5.1.2.

The context of the problem occurs during the setup phase, specifically when users are trying to configure hardware connections and ensure proper recognition of the adapter. The issue appears to be consistent among users attempting similar setups, leading to frustration as they seek guidance on how to modify the device tree appropriately.

The impact of this problem significantly hampers user experience, as it prevents them from utilizing the camera capabilities that the TC358743 adapter is supposed to provide. There is limited information available regarding specific hardware or software specifications beyond the JetPack version and the TC358743 adapter model.

Possible Causes

• Hardware Incompatibilities or Defects: The TC358743 adapter may not be fully compatible with the Orin Nano Dev Kit, leading to recognition issues.

• Software Bugs or Conflicts: There may be unresolved bugs in JetPack 5.1.2 that affect device tree configurations for specific hardware components.

• Configuration Errors: Incorrect settings in the device tree may prevent the system from recognizing the TC358743 adapter.

• Driver Issues: Missing or outdated drivers for the TC358743 could lead to failure in detection.

• User Errors or Misconfigurations: Users may not be following the correct procedures for modifying the device tree, leading to errors in configuration.

Troubleshooting Steps, Solutions & Fixes

1. Verify Hardware Connections:

   • Ensure that all physical connections between the Orin Nano Dev Kit and the TC358743 adapter are secure and correctly oriented.

2. Check JetPack Version:

   • Confirm that you are using JetPack 5.1.2 as stated. If possible, consider updating to a newer version if available, as updates may contain fixes for known issues.

3. Modify Device Tree:

   • Locate the device tree source file associated with your setup. This can typically be found in /boot/dtb/ or similar directories.
   • Edit the device tree source file to include configurations for the TC358743 adapter on CAM0.
   • Example command to edit:

     sudo nano /path/to/device_tree_source.dts
     

   • Look for sections related to camera devices and add or modify entries for CAM0 pointing to your TC358743 adapter.

4. Recompile Device Tree:

   • After making changes, recompile the device tree:

     dtc -I dts -O dtb -o /boot/dtb/your_device_tree.dtb /path/to/device_tree_source.dts
     

5. Check Kernel Logs:

   • Use dmesg or journalctl commands to check system logs for any error messages related to camera detection:

     dmesg | grep tc358743
     

6. Update Drivers:

   • Ensure that all relevant drivers are installed and up-to-date. Check Nvidia’s official documentation for any specific drivers needed for camera support.

7. Test with Alternative Configurations:

   • If possible, try using a different camera module or adapter to determine if the issue lies with the TC358743 itself.

8. Consult Documentation and Forums:

   • Review Nvidia’s official documentation regarding device trees and camera setup.
   • Visit forums or community discussions related to Nvidia Jetson products for additional insights and shared experiences from other users.

9. Seek Further Assistance:

   • If issues persist after following these steps, consider reaching out directly to Nvidia support or posting detailed queries in relevant forums for community assistance.

By following these troubleshooting steps, users can systematically diagnose and potentially resolve issues related to configuring their TC358743 adapter with the Nvidia Jetson Orin Nano Dev Kit.
