• The problem arises during initial setup and configuration of the development kit.
• There are conflicting statements from different users regarding the appropriate power supply method.

Relevant Specifications

• The Orin Nano Dev Kit has both a DC jack and a USB-C connector.
• Users mention experiences with powering the device using a power bank, indicating that alternative power sources may be a consideration.

Frequency and Impact

• This issue appears to be common among new users of the Orin Nano Dev Kit, as indicated by multiple inquiries in the forum.
• The confusion can lead to improper setup, resulting in users being unable to power their devices correctly, which affects their ability to start development projects.

Possible Causes

• Hardware Incompatibilities or Defects: If there are discrepancies in hardware versions, it may lead to confusion about power supply options.

• Software Bugs or Conflicts: Firmware may not correctly identify power sources, leading to erroneous behavior when attempting to power via USB-C.

• Configuration Errors: Incorrect assumptions about power supply methods could stem from misinterpretations of documentation or user experiences.

• Driver Issues: If drivers responsible for managing power input are not functioning correctly, it could lead to issues with recognizing USB-C as a power source.

• User Errors or Misconfigurations: Users may misconfigure their setups or fail to follow proper guidelines for powering the device.

Troubleshooting Steps, Solutions & Fixes

1. Verify Power Supply Method:

   • Confirm that you are using the correct power supply method as per the official documentation. According to user experiences, only the DC jack should be used for powering the Orin Nano Dev Kit.

2. Check Official Documentation:

   • Refer to the official datasheet for detailed specifications on powering the device. This will clarify which ports are meant for power versus data transfer.

3. Testing Power Supply Options:

   • If attempting to use a USB-C connector, ensure that it is connected to a compatible power source. However, based on user feedback, it is recommended to use the DC jack exclusively for powering up.

4. Using a Power Bank:

   • Users have successfully powered their Orin Nano Dev Kits using a power bank connected through the DC jack. If you opt for this method, ensure that your power bank meets the necessary voltage and current requirements.

5. Gather System Information:

   • Use terminal commands to check system logs for any errors related to power management. For example:

     dmesg | grep -i usb
     

   • This command can help identify if there are any issues with USB connections or power recognition.

6. Isolate Issues:

   • Test with different cables and adapters if you suspect hardware issues. Ensure that all connections are secure and that no damage exists on connectors.

7. Recommended Practices:

   • Always use recommended hardware as specified by Nvidia.
   • Keep firmware and drivers updated; check Nvidia’s official website for any updates related to your development kit.

8. Documentation Links:

   • For further assistance and updates regarding your device’s specifications and troubleshooting steps, refer to Nvidia’s official support page and datasheets.

By following these steps, users should be able to resolve any confusion regarding powering their Nvidia Jetson Orin Nano Dev Kit effectively.
