I have RaspberryPI with Arch Linux and everything was going well, until this morning when I tried to do my usual work on it, it sounds like nothing happening at all, I have checked with pintest (I use wiringPi with C) it gives me every thing is ok, also with
gives me the right mode of each pin but there is no output voltage at all and also the input doesn't work.
I don't know what information should I have too, your help will be appreciated
