Missing camera_overrides.isp file on NVIDIA Jetson AGX Orin with OX08B40 sensor - How to properly configure?

Content:
Hello everyone! While debugging the ISP on my NVIDIA Jetson AGX Orin, I found that the /var/nvidia/nvcam/settings/ directory is empty and missing the camera_overrides.isp file. I’m currently using an [OX08B40] sensor.

Problem Description:

  1. On L4T R35.3.1 system, is it necessary to manually add this file?

  2. How can I obtain the camera_overrides.isp file that matches my camera sensor?

  3. After copying the file, I performed permission modifications and service restart, but it didn’t take effect. How can I further troubleshoot?

Attempted Actions:

  • Checked directories like /usr/local/zed/firmware/ but couldn’t find relevant files

  • Executed the following commands to restart services:

    sudo chown root:root /var/nvidia/nvcam/settings/camera_overrides.isp
sudo chmod 664 /var/nvidia/nvcam/settings/camera_overrides.isp
sudo systemctl restart nvargus-daemon.service

  • Checked system logs but found no relevant loading records

Environment Information:

  • Hardware: NVIDIA Jetson AGX Orin

  • Operating System: Ubuntu 20.04.5 LTS (focal)

  • L4T Version: R35 (release), REVISION: 3.1

  • Camera Module: OX08B40

The issue you’re facing is related to the missing cameraoverridesisp file on your NVIDIA Jetson AGX Orin with OX08B40 sensor. This file is crucial for configuring the ISP (Image Signal Processor) on your device.

To properly configure the ISP, you’ll need to obtain the cameraoverridesisp file that matches your camera sensor. Here are the steps to follow:

  1. Check the NVIDIA Developer website: Visit the NVIDIA Developer website and search for the cameraoverridesisp file specific to your camera sensor (OX08B40). You can also check the NVIDIA Jetson AGX Orin documentation and release notes for any information on the file.
  2. Contact NVIDIA Support: Reach out to NVIDIA Support and provide them with your camera sensor details (OX08B40). They may be able to provide you with the correct cameraoverridesisp file or guide you on how to obtain it.
  3. Check the L4T source code: If you have access to the L4T source code, you can try searching for the cameraoverridesisp file within the code repository. This might give you an idea of where the file is located or how to generate it.
  4. Generate the file manually: As a last resort, you can try generating the cameraoverridesisp file manually. However, this requires in-depth knowledge of the ISP configuration and the camera sensor’s specifications.

To troubleshoot further, you can try the following:

  1. Check system logs: Verify that you’ve checked the correct system logs for any loading records related to the ISP configuration.
  2. Verify file permissions: Ensure that the file permissions are set correctly after copying the cameraoverridesisp file to the correct directory.
  3. Restart services: Restart the relevant services, such as the camera service, to ensure that the new configuration takes effect.
  4. Test the camera: After configuring the ISP, test the camera to ensure that it’s working correctly.

In comparison to other Jetson devices, the cameraoverridesisp file might be located in different directories or have different naming conventions. For example, on the Jetson Orin NX, the file might be located in /etc/camera/overrides/isp/.

To summarize:

  • The cameraoverridesisp file is essential for configuring the ISP on your NVIDIA Jetson AGX Orin with OX08B40 sensor.
  • You can try obtaining the file from the NVIDIA Developer website, contacting NVIDIA Support, or checking the L4T source code.
  • If you’re unable to find the file, you might need to generate it manually or seek further assistance from NVIDIA Support.

I hope this helps you resolve the issue!
