Hi, guys. I've got legOS compiled and running pretty happily on a redhat 6.0 and a 6.1 machine, after some fussing with settings, i've figured out that it wants to use /dev/ttyS1 for the serial port... however, once the firmware is downloaded, i (...)

I've managed to get a proximity detection working in legOS, using egcs 1.1.1 as the cross compiler. It has a very short range, and I haven't yet tested if the NQC variants have better range.

(...) You're right, that's the echo of what you're sending. This looks suspiciously like the problems many people had with gcc-2.9.5 compiled legOS on regular Linux boxes, you know.
