Hi, I tried to install brickos-0.2.6.10 and have been unsuccessful. I started by going to rpmfind.net to get the h8300 binutils and gcc. The versions were: h8300-hms-binutils-2.11.2-1 h8300-hms-gcc-3.0.1-2 The brickos make failed with the following: (...) (22 years ago, 18-Jul-03, to lugnet.robotics.rcx.legos)

Mike, IIRC, mm_start is the beginning of the heap. When the system or a user program requests memory (new in C++ or malloc/calloc in C) the memory is taken from this block (from mm_start to the end of memory) What might be confusing is how the (...)
