I am able to control fan using below commands on Jetson tx2 (L4T 32.5.1) :
to set speed:
echo 127 > /sys/devices/pwm-fan/target_pwm
(0 to 255)
cat /sys/class/hwmon/hwmon2/cur_pwm to read set value
but how to read tachometer?
I have tried:
return zero always.
Please suggest proper command to read tach
