Can Jetson Orin Nano support YUV422

Issue Overview

The discussion revolves around the compatibility of the Nvidia Jetson Orin Nano with YUV422 video formats, specifically concerning the integration of an FPGA camera module that outputs YUV422-8bit and YUV422-10bit formats. Users are experiencing uncertainty regarding whether they can utilize their camera module with the Jetson Orin Nano due to potential limitations in supported video formats.

Symptoms and Context

• Users are unsure if they can use their FPGA camera module with the Jetson Orin Nano.
• The issue arises during the setup phase when attempting to configure the camera output.
• There is confusion regarding the supported input data formats as specified in the device documentation.
• The problem appears to be consistent among users attempting to integrate similar hardware.

Hardware and Software Specifications

• Hardware: Nvidia Jetson Orin Nano, FPGA camera module capable of outputting YUV422 formats.
• Software: Jetson Linux Developer Guide, V4L2 (Video for Linux 2) drivers.

Impact on User Experience

The inability to effectively utilize the YUV422 formats may hinder users from achieving desired video processing capabilities, affecting applications reliant on specific video formats for image capture and processing.

Possible Causes

• Hardware Incompatibilities: The camera module may not be fully compatible with the Jetson Orin Nano’s input specifications.

• Software Bugs or Conflicts: There may be unresolved issues in the driver software that prevent proper handling of YUV422 formats.

• Configuration Errors: Incorrect settings in the device tree or driver configuration may lead to unsupported format errors.

• Driver Issues: The existing drivers may not support all variations of YUV422, particularly YUV422-10bit.

• User Errors or Misconfigurations: Users may not be configuring their devices correctly according to the required specifications.

Troubleshooting Steps, Solutions & Fixes

1. Check Supported Formats:

   • Refer to the Nvidia Jetson Orin Nano Series Modules Datasheet to verify supported input formats.
   • Confirm that YUV422 is listed among supported configurations.

2. Device Tree Configuration:

   • Ensure that the device tree is properly configured for CSI (Camera Serial Interface) settings.
   • Use the following command to check and configure pixel format:

     $ v4l2-ctl --list-formats-ext
     

3. Driver Setup:

   • If using a custom driver for YUV422, ensure it is correctly implemented. For example, consider using existing drivers like Toshiba TC358743 as a reference for developing your own.
   • Set up your driver configuration as follows:

     MEDIA_BUS_FMT_UYVY8_1X16
     

4. Format Configuration:

   • Configure your camera output to YUV422-8-bit (16-bpp). Use this command to set format and start streaming:

     $ v4l2-ctl --device /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=NV16 --set-ctrl bypass_mode=0 --stream-mmap --stream-to=frame.yuv --stream-count=100
     

5. Testing Different Configurations:

   • Experiment with different pixel formats supported by V4L2 to determine compatibility.
   • Test with both YUV422-8bit and YUV422-10bit configurations to see which works best.

6. Consult Documentation:

   • Review relevant sections of the NVIDIA Jetson Linux Developer Guide for further insights into driver programming and supported formats.

7. Reach Out for Support:

   • If issues persist, consider contacting support channels such as RidgeRun for assistance or further clarification on driver development.

Best Practices

• Always ensure that you are using the latest drivers and firmware updates for your hardware.

• Regularly consult official documentation when configuring devices to avoid common pitfalls.

Unresolved Aspects

Further investigation may be needed into whether specific limitations exist in handling YUV422-10bit formats, as users have noted varying success with different configurations.
