GPIO Problem [Solved]
-
Is there anything special about GPIO 0 and 1? The reason I ask is that I have a small opto-isolated relay board which works perfectly if I connect it to GPIO 0 or 1, but none of the other GPIO pins operate the relay despite gpio and fast-gpio apparently changing the pin status in the same way.
I have two Omega 2 boards and they both behave identically.
I'm running the latest firmware on both boards.[link text](link url)

Run
omega2-ctrl gpiomux get
in console and show results.
I had a very similar problem when writing an LCD driver and it all eventually ended up in having wronggpiomux
configuration.

@Patryk-Wychowaniec Thanks - that allowed me to see which pins are set to gpio duty and solved my problem!
