Jetson Xavier NX Board Reboot/Shutdown Issue During AI Model Inference

[abhirup.sinha]

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.

1. Set the power mode to MAX-N (15W) and maximize the clock speeds using the following commands:

sudo nvpmodel -m 0
sudo jetson_clocks

2. Activate all CPUs using the following command:

sudo bash -c "echo 1 > /sys/devices/system/cpu/cpu1/online"
activate all the 6 CPU's 

3. Run the object detection AI model and monitor the system's behavior.
 System Configuration:

Device**: NVIDIA Jetson Xavier NX
Operating System : Ubuntu 20.06
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.

Please enable serial port to dump log and see what happened before that reboot happened.

Also, which jetpack release are you using?

Jetpack 5.1.2[L4T 35.4.1] using and before that reboot happened it just get hang for few seconds and then it reboot sometimes and sometimes instead of reboot it get restart .

Hi,

Could you clarify what is the difference between your “reboot” and “restart”? I didn’t hear anyone ever talking about such comment that “instead of reboot, it get retart” Reboot and restart should be equal behaviors.

Also, I don’t need such comment. I need your log. Such comment basically provides none useful information. Everyone can say “my computer is dead” but the reason behind that could be various.

what is exactly mean by log ? and how can I get these log from the board ?
