Hi Michael, Thank you for sending me your brickOS.srec and .lds files. When I use these ones, the remote control works just fine, with or without the lr_startup and lr_shutdown calls, and with or without a running program. (...) Yes, exactly. I have (...)

Try removing the calls to lr_startup() & lr_shutdown(). I think these already get called outside of your program. (Sorry, don't have time to test right now).

Hi Christian, (...) No program, no help. If you send me the sources, I will take a look and try to figure out the problem. In fact, I use the remote control without a problem. Regards, Michael (21 years ago, 27-Jul-03, to lugnet.robotics.rcx.legos)
