Jetson How Jetson AGX turns on the fan

After Jetson AGX burns the image, the fan will automatically turn off after booting and restarting, how should I turn on the fan? I enter the following in the terminal

sudo /usr/bin/jetson_clocks 
sudo sh -c 'echo 255 > /sys/devices/pwm-fan/target_pwm'

But I found that there is no file with the path ‘pwm-fan/target_pwm’, is the fan not recognized successfully, or do you need to configure the pin FAN_PWM this pin is k62? will generate this file. How do I start the fan?
The default configuration for FAN_PWM is
GP_PWM4 Output Drive 1

Hi @DreamLan,

sorry this post got overlooked. It seems it was in the wrong category, so I’ll move it over into the Jetson forums.


Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks
