The firmware was successful. 
But I can not find the GPIO ports on the device. (like this https://www.youtube.com/watch?v=pV25gWwxSrM)

  Copy code 
On my Orange Pi Plus2 it works, but I can not even see the folders. 
 
I tried searching 
 
- k37mv1_bsp:/sys/class # find . -name "*gpio*"
 
 - ./misc/mtgpio
 
 - k37mv1_bsp:/sys/class #
 
  Copy code But he did not give results 
- k37mv1_bsp:/sys/class # cd misc/mtgpio/
 
 - k37mv1_bsp:/sys/class/misc/mtgpio # ls
 
 - dev pin power subsystem uevent
 
 - k37mv1_bsp:/sys/class/misc/mtgpio #
 
  Copy code It is not something with which to work. 
 
  
 
Maybe I'm doing something wrong? 
I tried to find all this through the adb shell. 
 
I'll write here, if I find something and wait for your answers
