hi all,
apologies if this question is answered elsewhere, i've done lots of
searching of the openmoko wiki and the web, and can't find an answer
i'd like to interface my freerunner with hardware switches to control
some software. i believe gpio is the best way to do this, and have
help from various bodies at my local maker space to do so.
problem is, i can't locate the gpio pins on the motherboard. are there
any schematics out there with their location? ideally something which
relates them to the nodes in /sys/class/gpio/
cheers,
If you aren't able to find the GPIOs, you could add an i2c-gpio
expander. The i2c pad locations are known:

Good Luck,
