Can the Nvidia Jetson Orin Nano Dev Board Output 24MHz Clock?

Issue Overview

The discussion revolves around the capability of the Nvidia Jetson Orin Nano Dev board to output a clock frequency of 24MHz, similar to its predecessor, the TX2. Users are questioning whether the Orin Nano can be set to this frequency by default and are seeking guidance on how to modify the clock settings if necessary. Symptoms reported include confusion regarding the default clock settings and a lack of clear documentation on how to change these settings. The issue arises during the setup phase, particularly when configuring camera modules that require specific clock frequencies for proper operation. The frequency of this issue appears to be consistent among users attempting to integrate camera modules with the Orin Nano. This problem impacts user experience by complicating the setup process and potentially hindering functionality when interfacing with external devices.

Possible Causes

• Hardware Incompatibilities: Some users have reported that certain camera modules (like IMX477) do not work with third-party carrier boards, which could lead to confusion regarding clock settings.
• Software Bugs or Conflicts: Users may encounter issues due to bugs in the JetPack software or conflicts between different versions of software components.
• Configuration Errors: Incorrectly configured settings in the device’s software could prevent it from outputting the desired clock frequency.
• Driver Issues: Outdated or incompatible drivers may not support the required clock settings for specific hardware configurations.
• Environmental Factors: Power supply issues or overheating could affect performance and clock output.
• User Errors: Misunderstandings about how to configure settings or use available resources may lead to incorrect setups.

Troubleshooting Steps, Solutions & Fixes

1. Verify Default Clock Settings:

   • Check the device’s current clock output using relevant commands or through device configuration files.
   • Ensure that you are referencing the correct documentation for your specific model.

2. Modify Clock Settings:

   • To set the clock output to 24MHz, modify the configuration file as follows:

     mode0 { // OV5693_MODE_2592X1944
         mclk_khz = "24000"; // Set clock to 24MHz
         num_lanes = "2";
     }
     

   • This modification can typically be found in your camera driver or sensor configuration files.

3. Consult Documentation:

   • Refer to the official Nvidia programming guide for further details on configuring device properties and clock settings. Documentation can be accessed here.

4. Check for Driver Updates:

   • Ensure that all drivers are up-to-date by using the SDK Manager, which can help resolve compatibility issues.

5. Test with Different Hardware Configurations:

   • If using third-party hardware, consider testing with official Nvidia components to rule out compatibility issues.

6. Log and Review Errors:

   • If issues persist, export logs from your setup process using SDK Manager and review them for any error messages that might indicate where the problem lies.

7. Seek Community Support:

   • Engage with forums such as Nvidia Developer Forums or Reddit communities focused on Jetson products for additional troubleshooting tips from other users who may have faced similar issues.

8. Best Practices for Future Prevention:

   • Always refer to official documentation before making hardware changes.
   • Regularly check for updates from Nvidia regarding software and driver releases.
   • Maintain a stable power supply and ensure proper cooling for your device during operation.

By following these steps, users should be able to diagnose and potentially resolve issues related to setting the desired clock frequency on their Nvidia Jetson Orin Nano Dev board.
