gumstix and roofnet

Today we connected to the gumstix over the serial cable and figured out how to flash the device and setup a new root file system. We have compiled roofnet/click for gumstix, configured busybox to provide the necessary tools for future work and setup the image over the serial line. We have also set the wired network interface to be available on a static IP address, which should not cause any issues in the future.
