[Fan mode] How to fix fan mode

Hi, I want to fix fan mode even after rebooting.

Board: Jetson Xavier NX
Jetpack: 5.1.2

What should I do?

Thanks.

Hi 20171522,

Are you using the devkit or custom board for AGX Xavier?

What do you mean about “fix fan mode”?
Do you mean that you want the fan keep working at a constant speed?

Are you using the devkit or custom board for AGX Xavier? : Yes
Yes, I want it to run at full speed

So, you are using “Devkit” or “Custom Board”…?

Please run the following commands for this use case

$ sudo su
# systemctl stop nvfancontrol
# echo 255 > /sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1

Sorry, I misunderstand.

I use “Custom Board”.

And I run your advice but this commands are not working after reboot.

I should maintain configuration (full speed of fan) after reboot.

Thanks.

What do you mean about “not working”?
Do you mean that you run these command failed or not meet your requirement?

You could put those commands in script and load them after boot up to run them automatically.
