Hello,
if not mistaken, sysfs creates the '/sys/class/gpio' directory structure and the interface to the actual pins, right?
On an older centos version (7.1.1503), it is there however on 7.8.2003 it's not.
Am I missing something?
The gpio handling was changed several kernels ago, IIRC you need you use libgpio now.
yes, I found that out last night, late
I think I built it some time ago and put it here https://people.centos.org/pgreco/libgpiod/, let me know if it helps.
I will try that one, because the one I compiled didn't seem to be working. (I tried compiling 1.4.3, which 'seemed' to compile without errors/warnings, but I couldn't compile 1.5.x because of some kernel-header/linux-header issues.
