Hmm. Where do you type
gpio export? That sounds like it's inside Python's wiringpi library? Do you shut Python down first? It might be interfering somehow.If
/sys/class/gpio/exportdoesn't work, you'll need to get that sorted first. That's pretty much the most basic way of using GPIO, and if it doesn't work then I guess you have other issues. Maybe you could ask on the Pi forum, or does someone else have some ideas?Have you tried with any other GPIOs? It might be that 23 is used by something else?
