Orange Pi Zero Plus using Ubuntu: problem with GPIO

py5bk

Hello friends!

I'm using on my Orange Pi Zero + board the Oficial Ubuntu image of Orange Pi. At first it's perfect. I made the package installations perfectly.
But I'm having trouble working with the gpio pins. I used Armbian before, but I'm having trouble with the analog audio card when I use Armbian, which is not the case with Ubuntu.
My problem when using the Ubuntu image in my Orange Pi Zero + is that the gpio is different. Its path is /sys/class/gpio_sw instead of /sys/class/gpio ..
I would like to know if it is possible to change this system from gpio to the one I can work like armbian ..
I usually command the ghosts as follows:

1. echo 14 > /sys/class/gpio/export
   
2. echo out > /sys/class/gpio/gpio14/direction
   
3. echo 0 > /sys/class/gpio/gpio14/value
   
4. echo 1 > /sys/class/gpio/gpio14/value

Copy code

Can someone help me with this?

From now on I am very grateful for the attention!
