(...) The limit is in the checksum routine built into the RCX - it only does a sum up to 0xCC00! So you may need to fiddle with firmdl to allow a larger SREC image, but only checksum up to 0xcc00. Hope this helps. Ralph Hempel (24 years ago, 9-Mar-01, to lugnet.robotics.rcx.legos)

Hi! I'm using legOS 0.2.4 on Cygwin, and since memory is tight, I thought I'd try statically compiling my program to an .srec file, and using firmdl3 to download it, since I can do without the keys,conio,task, and memory managment stuff. This works (...) (24 years ago, 9-Mar-01, to lugnet.robotics.rcx.legos)
