Hi

I have a nanopi-m1 board and connected a simple dc motor to GPIO15(pin10). I used this commands to run the mtor but nothing happend else making a folder named gpio15 in /sys/class/gpio path!

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

Also I tried it with GPIO18 (pin12) and didn't work!

Very thank you guys, specially zador.blood.stained

The key of problem was this:

Also physical pin 10 is GPIO G7 which would be pin 199 for sysfs interface.

 

 

I thought(as they say in their advertise) the GPIO pins are same as what they are in raspberryPi3 but they are completely different! and it was the problem! and wasting time for 3 days!

 

Anyway, I am trying to connect a LCD to my board(as you can see here: https://github.com/notro/fbtft/issues/428)and when I changed the pins from 25->1 , 24-> 201, 18->6, in this command:

sudo modprobe fbtft_device custom name=fb_ili9341 gpios=reset:1,dc:201,led:6 speed=16000000 rotate=90 bgr=1

My problem changed from error -22(unknow device)  to error -16(Device or resource busy).

[ 1627.047442] fb_ili9341: probe of spi0.0 failed with error -16

So what I get this error and how can I fix this error?
