BPI r3 mini openwrt fan

[Pschiit]

Hi, I have installed the snapshot from openwrt and I got it to work but the fan doesn’t turn on. During booting I hear it running at full speed then it turn off. /sys/class/hwmon/hwmon1/pwm1 is set to 255 and pwm_enable to 1.

[image] echo 50000 > /sys/class/thermal/thermal_zone0/trip_point_4_temp echo 50000 > /sys/class/thermal/thermal_zone0/trip_point_3_temp echo 50000 > /sys/class/thermal/thermal_zone0/trip_point_2_temp echo 50000 > /sys/class/thermal/thermal_zone0/trip_point_1_temp This will activate the fan at 50°c, for 45°c change the value to 45000 as mentioned in the screenshot, the file is : /etc/rc.local
