BPI-W2 fan interface does not work(fixed)

Measuring fan interface only 0.2-0.5 Volts. This voltage is not a nominal value of 5 volts. Can this interface be modified by software?

HI: you need to enable FAN GPIO pin.


  echo 15 >/sys/class/gpio/export
  echo out >/sys/class/gpio/gpio15/direction 
  echo 1 >/sys/class/gpio/gpio15/value
