Hi, I am working with Jetson Xavier AGX and L4T 32.4.3 I wanted to read and change fan speed. How to enable tachometer?
enable tach :
I have tried this command
echo 1 > /sys/devices/pwm-fan/tach_enable
and getting this error bash: echo: write error: Operation not permitted
these are working fine for read/write rpm:
set speed :
echo 255 > /sys/devices/pwm-fan/target_pwm
read tach :
Same commands worked for Nano but have issue in NX, is there any other command or way to enable tachometer in NX?
