Error connecting CSI Camera Jetpack 6.0 – nvbuf_utils: dmabuf_fd mapped entry NOT found and a lot more errors

Issue Overview

Users are experiencing connectivity issues with the Raspberry Pi High Quality Camera 1 on the Nvidia Jetson Orin Nano after upgrading from JetPack 5.1.1 to JetPack 6.0. The camera, which previously functioned correctly, now fails to operate, suggesting a potential driver issue since it still works on a Raspberry Pi.

Symptoms:

• Errors during camera initialization and streaming.
• Specific error messages include:
  • "Internal data stream error" when using GStreamer commands.
  • "Remote I/O error" when attempting to set video format with v4l2-ctl.
  • "nvbuf_utils: dmabuf_fd -1 mapped entry NOT found" during GStreamer pipeline execution.

Context:

• The issue arises during setup and operation of the camera using various commands and applications (GStreamer and ROS2).
• Users have reported inconsistent behavior, with some commands failing while others provide partial success.

Hardware/Software Specifications:

• Device: Nvidia Jetson Orin Nano
• Camera: Raspberry Pi High Quality Camera 1
• Software: JetPack 6.0

Frequency of Issue:

The problem appears to be consistent among users who upgraded to JetPack 6.0, indicating a widespread issue rather than isolated incidents.

Impact on User Experience:

This issue significantly hampers the functionality of the camera, affecting applications that rely on video capture and processing, thereby limiting the usability of the Jetson Orin Nano for projects requiring camera input.

Possible Causes

• Driver Issues: The upgrade to JetPack 6.0 may have introduced incompatibilities or bugs in the camera drivers.

• Software Bugs or Conflicts: New software versions may not fully support existing hardware configurations, leading to errors in camera initialization.

• Configuration Errors: Incorrect settings or parameters in GStreamer commands could be causing failures in establishing a video stream.

• Environmental Factors: Power supply issues or overheating could affect device performance, although not explicitly mentioned in user reports.

• User Errors: Misconfigurations during setup or command usage may lead to failures in capturing video streams.

Troubleshooting Steps, Solutions & Fixes

1. Verify Camera Connection:

   • Ensure that the camera is properly connected to the Jetson Orin Nano.
   • Check for any physical damage or loose connections.

2. Reconfigure Camera Settings:

   • Use jetson-io to enable the IMX477 camera sensor if not already done.
   • Confirm that all settings match those used in JetPack 5.1.1.

3. Test GStreamer Commands:

   • Replace v4l2src with nvarguscamerasrc in GStreamer commands:

     gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM), width=(int)640, height=(int)480, framerate=(fraction)30/1, format=(string)NV12' ! nvvidconv ! 'video/x-raw, format=(string)I420' ! xvimagesink -ev
     

   • Ensure that all elements are correctly linked and that queues are added if necessary to manage buffering.

4. Check Video Format Settings:

   • Use v4l2-ctl to set video formats and ensure they are compatible:

     v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --stream-mmap --set-ctrl=sensor_mode=0 --stream-count=100 -d /dev/video0
     

5. Run Compliance Tests:

   • Execute v4l2-compliance to check for driver compatibility and functionality:

     v4l2-compliance -d /dev/video0
     

6. Reflash Jetson OS:

   • If issues persist after troubleshooting, consider reflashing the Jetson Orin Nano with a fresh installation of JetPack 6.0 as reported by some users as a successful fix.

7. Update Drivers and Firmware:

   • Check for any available updates for drivers or firmware related to the Jetson Orin Nano and apply them as necessary.

8. Consult Documentation:

   • Review Nvidia’s official documentation for any changes in API or driver support between JetPack versions that could affect camera functionality.

9. Community Support:

   • Engage with community forums for additional insights or solutions shared by other users facing similar issues.

By following these steps systematically, users can diagnose and potentially resolve the connectivity issues with their CSI cameras on the Nvidia Jetson Orin Nano after upgrading to JetPack 6.0.
