Hi all,
What would be best (=most reliable) way to control i/o lines with Beagle in Ubuntu?
Does anybody have examples to read and write i/o pin at external connector on Beagle?
Thank you in advance.

If you are referring to the omap's gpio pins, then you should take a
look at Documentation/gpio.txt in the linux kernel tree. The kernel
exposes gpio pins in /sys/class/gpio (iirc).

Here is a good link for GPIOs:

If you want to edit the files in /sys/class/gpio/ as a normal user you will need to chmod export, unexport, the gpioX/value, and possibly the gpioX/direction files.
Hope this helps.
