Connecting Video Grabber M.2 to Jetson Orin Nano

Issue Overview

Users are experiencing difficulties in detecting a video grabber connected to the M.2 PCIe slot of the Nvidia Jetson Orin Nano developer kit. The specific symptoms include:

• The video grabber, an Eco Capture Dual SDI M.2 from Magewell, is not recognized when executing the command lsusb in the terminal.
• Cameras connected to the video grabber are not detected in the /dev/video* directory.
• The Jetson Orin Nano is running Jetpack version 5.1.2.

The problem occurs during the setup phase when users attempt to connect and configure their video input devices. Despite installing the necessary drivers for the Magewell video grabber, users find that the device remains undetectable. This issue can significantly impact user experience, particularly for those relying on real-time video processing or streaming applications.

Possible Causes

• Hardware Incompatibilities or Defects: The video grabber may be incompatible with the Jetson Orin Nano or could be defective, leading to detection issues.

• Software Bugs or Conflicts: There may be bugs in Jetpack 5.1.2 or conflicts with other installed software that prevent proper device recognition.

• Configuration Errors: Incorrect configuration settings in the device tree or other system files could hinder detection of connected devices.

• Driver Issues: If the drivers for the Magewell video grabber are not correctly installed or compatible with the current version of Jetpack, this can lead to detection failures.

• Environmental Factors: Issues such as inadequate power supply or overheating could affect device performance and recognition.

• User Errors or Misconfigurations: Users may overlook essential steps in connecting or configuring their devices, leading to detection problems.

Troubleshooting Steps, Solutions & Fixes

1. Check Device Detection:

   • Run the command:

     sudo lspci -v
     

   • This will list all PCIe devices. If the video grabber is not listed, it indicates a connection or hardware issue.

2. Verify Driver Installation:

   • Ensure that the drivers for the Magewell video grabber are properly installed. Reinstalling them may resolve potential issues.

3. Inspect Hardware Connections:

   • Physically check all connections to ensure that the video grabber is securely connected to the M.2 PCIe slot.

4. Test with Different Hardware:

   • If possible, test another video grabber or connect a different device to the same M.2 slot to determine if the issue lies with the original hardware.

5. Review Device Tree Configuration:

   • Investigate whether any changes are necessary in the device tree for proper recognition of M.2 devices.

6. Power Supply Check:

   • Ensure that your power supply meets the requirements for both the Jetson Orin Nano and any connected peripherals.

7. Replace Faulty Equipment:

   • As noted in user replies, if all troubleshooting steps fail and no detection occurs, consider replacing the video grabber if it is suspected to be faulty.

8. Update Firmware and Software:

   • Check for any available updates for Jetpack or firmware updates for connected devices that might resolve compatibility issues.

9. Consult Documentation:

   • Refer to Nvidia’s official documentation for specific instructions related to connecting M.2 devices and troubleshooting PCIe issues.

10. Preventive Best Practices:

    • Always ensure that you are using compatible hardware and keep your software up-to-date to minimize future issues.

Unresolved aspects of this issue include potential software bugs within Jetpack 5.1.2 that may require further investigation from Nvidia’s support team or community forums for additional insights and updates on compatibility with specific devices like Magewell’s Eco Capture Dual SDI M.2 video grabber.
