HD-SDI Video Interface with Jetson Orin Nano

Issue Overview

The discussion revolves around the challenge of interfacing HD-SDI video signals with the Nvidia Jetson Orin Nano development board. Users are seeking guidance on how to convert HD-SDI video into compatible formats such as MIPI, PCIe, or USB using external integrated circuits (ICs) on a custom carrier board.

Symptoms and Context:

• Users are experiencing difficulties in understanding the conversion process of HD-SDI video signals.
• The issue arises during the design phase of a carrier board intended for the Jetson Orin Nano.
• Specific hardware mentioned includes the Jetson Orin Nano and external ICs required for video signal conversion.

Frequency and Impact:

• The topic appears to be a common concern among developers working with the Jetson platform, indicating a need for clarity on interfacing HD-SDI signals.
• The inability to effectively convert and interface video signals can significantly hinder project development, especially for applications requiring real-time video processing.

Possible Causes

• Hardware Incompatibilities: The Jetson Orin Nano may not natively support HD-SDI input, necessitating additional hardware for conversion.

• Software Bugs or Conflicts: There may be limitations or bugs in the software stack that prevent proper handling of video input formats.

• Configuration Errors: Incorrect configurations on the carrier board or within the software could lead to failures in recognizing or processing the video signal.

• Driver Issues: Lack of suitable drivers for the external ICs used for conversion might lead to compatibility problems.

• Environmental Factors: Power supply issues or overheating could affect the performance of both the Jetson board and the external ICs.

• User Errors or Misconfigurations: Users may not be familiar with the necessary steps to correctly set up their hardware and software environments for HD-SDI interfacing.

Troubleshooting Steps, Solutions & Fixes

1. Consult Existing Solutions:

   • Reach out to Nvidia’s partners or consult the Jetson Ecosystem resources for pre-existing solutions tailored for HD-SDI interfacing. This can provide insights into recommended ICs and configurations.

2. Gather System Information:

   • Use commands like dmesg and lsusb to check for connected devices and any error messages related to USB or PCIe devices.
   • Ensure that all necessary drivers are installed by checking their status using sudo apt list --installed.

3. Isolate the Issue:

   • Test with different external ICs designed for HD-SDI to MIPI, PCIe, or USB conversion to determine if specific hardware is causing issues.
   • If possible, use a different Jetson board to see if the problem persists across different hardware setups.

4. Configuration Verification:

   • Double-check all connections and configurations on the carrier board. Ensure that power supplies are adequate and that all components are properly seated.
   • Review configuration files related to video input settings in your development environment.

5. Driver Updates:

   • Visit Nvidia’s official website to check for any driver updates that may enhance compatibility with external ICs used for video signal processing.

6. Documentation Review:

   • Refer to Nvidia’s developer documentation regarding video interfaces and supported formats for detailed guidance on setup and troubleshooting.

7. Best Practices:

   • Always ensure that your development environment is up-to-date with the latest software patches and firmware updates.
   • Consider using established reference designs from Nvidia or other developers as a baseline for your carrier board design.

8. Community Engagement:

   • Engage with community forums or groups dedicated to Nvidia Jetson development. Sharing experiences can lead to discovering effective solutions that others have successfully implemented.

Recommended Approach:
Consulting Nvidia’s partners and leveraging community resources appears to be a widely supported method among users facing similar challenges, indicating its effectiveness in resolving issues related to HD-SDI interfacing with Jetson devices.

Unresolved Aspects:
Further investigation may be needed regarding specific external IC recommendations and their compatibility with various formats. Additionally, more detailed documentation from Nvidia regarding direct support for HD-SDI would benefit developers in this area.
