I am trying to configure my UDOO so that I can make the I2C interface available for linux. I have tried everything, yet I can not figure out how the UDOO pinout multiplexing is supposed to work. Can it be done from the terminal? Or is it supposed to work another way? I am currently running Arch Linux (ALARM). The only thing I need is to learn how a generic multiplexing is done so I can access any pin functionality from the ARM, and not the arduino. I didn't find any single thread on the net related to this subject, and the user manual only speaks about some misterious header files. Please help :geek:
