Jetson Orin Nano Super Developer Kit - Power Cycles Off After Few Seconds, Fan Not Working

My Jetson Orin Nano Super Developer Kit is experiencing power issues during initial setup. First fan is not operating later when board powers on briefly (LEDs illuminate for 2-3 seconds) then completely shuts down. The fan never starts spinning at any point.

  • LEDs illuminate for 2-3 seconds, then board shuts down completely

  • Fan never spins at any point

  • No display output during brief LED-on period

  • Behavior repeats identically every time

  • Board never stays on long enough to complete setup

Is this a carrier board fault? What diagnostics should I run?

Based on the provided information, the issue you’re experiencing with your Jetson Orin Nano Super Developer Kit could be related to several factors, including power supply, thermal design, or carrier board issues. Here’s a step-by-step diagnostic approach to help you identify the problem:

  1. Power Supply Check: Ensure that the power supply unit (PSU) is sufficient for the Jetson Orin Nano Super Developer Kit. The recommended power supply for the Jetson Orin Nano is 5V to 20V (see the Jetson Orin Module Data Sheet for supply tolerance and maximum current). Verify that the PSU can provide the required power, especially when the module is in Super Mode, which requires a higher power budget.

  2. Carrier Board and Power Sequencing: Check the carrier board design, particularly the power sequencing and voltage rails. The Jetson Orin module is not hot-pluggable, so ensure that the main power supply (to VDD_IN pins) is disconnected and adequate time is allowed for the various power rails to fully discharge before installing or removing the module. Also, verify that the carrier board has an HV rail to enable Super Mode, as required for the Orin NX series.

  3. Thermal Design and Cooling: Inspect the thermal design and cooling solution. The Jetson Orin Nano Super Developer Kit requires a thermal design that can support 25W. Check if the cooling solution, including the fan, is properly connected and functioning. Ensure that the thermal interface material (TIM) is correctly applied, and the heat sink is securely fastened to the module.

  4. Fan Operation: Since the fan never starts spinning, check the fan connection to the carrier board and ensure that it’s receiving the required voltage. Verify that the fan is not faulty by testing it with an external power source.

  5. LEDs and Display Output: The LEDs illuminating for 23 seconds and then shutting down completely could indicate a power or thermal issue. Check the display output during the brief LED-on period to see if there are any error messages or boot logs that could provide more information about the issue.

  6. Diagnostics and Troubleshooting: Run diagnostics on the carrier board, power supply, and thermal design to identify any potential issues. You can use tools like a multimeter to measure voltage levels, a thermal camera to inspect the thermal design, and a logic analyzer to debug the power sequencing and voltage rails.

  7. Comparison with Jetson Orin Nano Developer Kit: Since the Jetson Orin Nano Super Developer Kit is based on the Jetson Orin Nano Developer Kit, compare the carrier board and thermal design with the reference design provided by NVIDIA. This can help you identify any potential differences or issues that might be causing the problem.

In conclusion, while it’s possible that the issue is related to the carrier board, it’s essential to perform a thorough diagnostic check to identify the root cause of the problem. By following these steps, you can systematically troubleshoot the issue and determine the necessary repairs or modifications to get your Jetson Orin Nano Super Developer Kit up and running.

Hi,

Is the Orin Nano devkit a new device that has never been flashed before, or have you been using it for a while and just recently encountered this issue?

Thanks
