Hey all,
I am trying to export GPIO1_3 and I’m getting an error:
root@omap:~# echo 35 > /sys/class/gpio/export
su -: echo: write error: Device or resource busy
Any ideas on how to remedy this?

Most likely because the 1-wire module already reserved this pin.
This is my own question (on the angstrom distribution), maybe the
information helps:

Cool. So is there a way to drop the 1-wire module without recompiling the kernel?
is it a module or compiled in the kernel?
I am not with my beagle here now so try this:
lsmod
check if the 1-wire module is on the list. If it is just do:
rmmod <module_name>
but if it is compiled in I believe there is no way to disable it (maybe by boot parameters but I don´t know).
