its like werecatf says you have the gpio sysfs enabled so its not your kernel youre trying the wrong pin!

can you share os image with us ? i wanna test with ur kernel

There's nothing wrong with the Armbian - kernel, WiringOP should work just fine with it. Did you grab WiringOP from my github or from somewhere else? And are you trying to run the app as root?

@WereCatf

I used in my code next fix

#define PIN_RPM 7
char clearPinRPM[80];
sprintf (clearPinRPM, "%s %d", "gpio unexport ", PIN_RPM);
system(clearPinRPM);

Copy code

anything more cleverly, I could not

it works now

I don't like unexporting and exporting the pin again as a workaround; it's ugly and clunky. I made a change that, as far as I can tell, should fix the issue. Could you test the latest code from https://github.com/WereCatf/WiringOP and report back?

@WereCatf

I just tested your new code.
It works great !

Thank you for your work!!!

yes , i cloned latest source wiringop your repo ,and i recompile succesfully ,
i check the gpio-sunxi module its not loaded
and then i try to compile your wiringisr code on page 7 only i change the button pin 16 to 14
try to run but not interrupted eventcounter

Are you running the application as root?

Whichever fucking mouth-breathing troglodyte wrote the original WiringOP should be ashamed and ridiculed publicly, the code is a fucking atrocious mess and I keep finding bugs and stupidities there because they couldn't be arsed to do it properly. I just committed another fix, but I'd have to rewrite a whole lot of the code there to fix it all properly. Then there's the issue that WiringPi itself was never designed with non-RPi hardware in mind and has all sorts of stupidities there because of this.

I should just scrap the whole thing and write an alternative to WiringPi that is actually easily extendable to new boards and different pin-setups and interfaces
