Interrupt EINT31(PI19)

Hello! Please help me configure the interrupt from EINT31(PI19).
CPU: A20
Board: LIME2
arm-linux-gnueabihf-gcc

What image do you use? For older images you need to edit the fex/bin and define it is for that function (and remove the pin from other usages). It is similar for newer Olimage images but instead of fex/bin you need to change the DTS.

Thank You! I'm use DTS (sun7i-a20-olinuxino-lime2.dts).
1. What to write in dts?
2. How to enable an interrupt in a C program?

Thanks for your solution admin LubOlimex. I'm also looking to configure the interrupt from EINT31.

Thank You. I'm sorry to be late with the reply.
Used a hardware timer instead

Thank you both. I was having the same problem and didn't know how to solve it until I read this article.
