G'day, (...) Do you know if/how they were able to fix the problem? Btw. I used binutils 2.9.1 and gcc 2.95.2 (with the patches for the interrupts applied) to create the legOS and gcc 2.8.1 to build the cross compiler. Carsten (25 years ago, 1-Dec-99, to lugnet.robotics.rcx.legos)

(...) 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. Maybe you should try downloading a kernel known to work? Markus. (25 years ago, 30-Nov-99, to lugnet.robotics.rcx.legos)
