Is there a complete instruction for installing BrickOS on Linux? I'm particularly interested in details involving creating a cross-compiler and getting the USB tower to work. I've looked at the windows instructions, and have tried to work from them, (...) (21 years ago, 4-Dec-03, to lugnet.robotics.rcx.legos)

Hello out there, maybe someone can explain to me why the current brickOS release seems to have msleep()-amnesia ;-) We've been testing the data transfer to our Lepomux device. For some strange reason we were still using kernel 0.2.6.07nmChg with a (...) (21 years ago, 2-Dec-03, to lugnet.robotics.rcx.legos)
