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.

Thanks!
