Orin Nano Adapts To IMX715 Image Segmentation

Issue Overview

Users are experiencing issues when attempting to adapt the binning mode of Sony’s IMX715 sensor using the Nvidia Jetson Orin Nano Dev board. The primary symptoms include the inability to obtain a normal image despite modifications to parameters such as pix_clk_hz and embedded_metadata_height. This issue arises during the setup phase, specifically while configuring the camera for image segmentation tasks. The hardware involved is the Jetson Orin Nano, and users have reported this issue consistently, indicating it may be a common problem affecting multiple users. The impact on user experience is significant, as it prevents successful image capture and processing, which is critical for applications relying on this functionality.

Possible Causes

1. Hardware Incompatibilities or Defects: The IMX715 sensor may not be fully compatible with the Jetson Orin Nano, leading to communication issues.
2. Software Bugs or Conflicts: There could be bugs in the software stack that prevent proper handling of the sensor’s configuration.
3. Configuration Errors: Incorrect settings for pix_clk_hz or embedded_metadata_height may lead to failure in obtaining valid images.
4. Driver Issues: Outdated or incorrect drivers for the camera module could hinder proper functionality.
5. Environmental Factors: Power supply inconsistencies or overheating may affect performance.
6. User Errors or Misconfigurations: Users may not be setting up the parameters correctly, leading to improper operation.

Troubleshooting Steps, Solutions & Fixes

1. Boost Clock Frequencies:

   • Increase the clock rates for various components to ensure they are operating at optimal levels. Use the following commands:

     sudo su
     echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
     echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked
     echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked
     echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/mrq_rate_locked
     

   • Check maximum rates:

     cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/vi/rate
     cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/isp/rate
     cat /sys/kernel/debug/bpmp/debug/clk/nvcsi/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate
     cat /sys/kernel/debug/bpmp/debug/clk/emc/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/emc/rate
     

2. Verify Configuration Settings:

   • Ensure that pix_clk_hz and embedded_metadata_height are set correctly according to the specifications of the IMX715 sensor.

3. Check Driver Versions:

   • Confirm that you are using the latest drivers for both the Jetson Orin Nano and the IMX715 sensor. Update if necessary.

4. Test with Different Hardware Configurations:

   • If possible, test with another camera module known to work with the Jetson Orin Nano to isolate whether the issue lies with the sensor or the board.

5. Monitor System Logs:

   • Gather trace logs during operation to identify any errors or warnings that may indicate what is going wrong.

6. Consult Documentation and Community Resources:

   • Refer to Nvidia’s official documentation for any updates regarding compatibility and configuration settings.
   • Engage with community forums for additional insights and shared experiences from other users facing similar issues.

7. Preventive Measures:

   • Regularly update firmware and software components associated with both the Jetson Orin Nano and connected peripherals.
   • Implement best practices for power management and thermal regulation to avoid hardware malfunctions.

By following these troubleshooting steps, users should be able to diagnose and potentially resolve issues related to adapting the IMX715 sensor with their Jetson Orin Nano Dev board.
