Jetson nano sudo /opt/nvidia/jetson-io/jetson-io.py interface flashes and turns off

Currently I use jetpack :

Please help me, Thanks

I won’t be able to answer, but a lot of this likely depends on which carrier board you use. Some questions to get started:

• Is this a Nano dev kit? Or is this some third party device?
• Was all of the involved software installed via the SDK Manager (or part of the SD card)?
• What is the release you see with “`head -n 1 /etc/nv_tegra_release”?
• Is the kernel or device tree modified in any way?
• What shows up from the command “uname -r”?

Thanks for the answer

1. Is this a Nano dev kit? Or is this some third party device?

• I’m using Jetson nano Developer kit

2. Was all of the involved software installed via the SDK Manager (or part of the SD card)?

• I use memory card and install according to “https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#write” to install the operating system for Jetson nano

3. What is the release you see with “`head -n 1 /etc/nv_tegra_release”?

• R32 (release), REVISION: 7.3, GCID: 31982016, BOARD: t210ref, EABI: aarch64, DATE: Tue Nov 22 17:30:08 UTC 2022

4. Is the kernel or device tree modified in any way?

• I haven’t modified anything with the board just “sudo apt-get update” and “sudo apt-get upgrade”

5. What shows up from the command “uname -r”?

• 4.9.299-tegra

Thanks for the answer
i have that file

[linuxdev]

That file with the current release should probably work. Someone else would have to help answer why it causes shutdown. One possibility I can think of is that if for some reason power requirements go up momentarily, then maybe the power supply is insufficient (but I doubt that is the cause; however, Jetsons are sensitive to power supply regulation, so this is a possibility).
