I hope this message finds you well.

I am writing to seek assistance regarding an issue I am experiencing with my NVIDIA Jetson Xavier NX board. When operating the board in MAX-N mode with all CPUs activated, the board frequently shuts down or reboots automatically while running an object detection AI model.

Observations and Details:

  • Power Supply: 5V, 4A
  • Temperature: Maximum observed temperature is 40-42°C
  • Cooling Measures: The board is equipped with a heat sink and a fan
  • Issue Description:
    • Upon starting the AI model, the board performs as expected for a few iterations.
    • After a short period, the board hangs for a few seconds and subsequently reboots or sometimes shuts down directly.

Set the power mode to MAX-N (15W) and maximize the clock speeds using the.
sudo nvpmodel -m 0
sudo jetson_clocks

Activate all CPUs using the following command:
sudo bash -c “echo 1 > /sys/devices/system/cpu/cpu1/online”
activate and using all the 0-5 CPUs

  1. Run the object detection AI model and monitor the system’s behavior.

System Configuration:

  • Device: NVIDIA Jetson Xavier NX
  • Operating System: Ubuntu 20.04
  • Cooling Solution: Heat sink and fan installed

Despite the cooling measures and a stable power supply, the issue persists. I would appreciate your guidance on how to mitigate this issue and any recommendations for maintaining stable performance under high load conditions.

Thank you for your support.

Hi,

Do you use our devkit or a custom board?
Are you able to share the tegrastats log right before the shutdown?

Thanks.

it is custom based board , and I want to know something can we use the highest power mode
means using the 6 cores with 20 W by using the 8 mode (sudo nvpmodel -m 8)

Hi,

Does the reboot issue only happen on the custom board?
Could you check if the same app can run well on the devkit?

In the above document, it mentions:

The Jetson Xavier NX Developer Kit requires a 9−20V power supply.

As you are using a custom board, please check your power supply requirement accordingly.

Thanks.
