Hi there. I'm working on a project that requires to have a clear picture of how the kernel is actually orginized, and of course, the API. So, I've found a quite good link where the picture is clear: (URL) the problem is that I actually does not have (...) (22 years ago, 3-Apr-03, to lugnet.robotics.rcx.legos)

Carlos, Last time I checked you were unable to compile the kernel using winLegOS or DJGPP. For those not familiar with the inner workings on winLegos it is essentially a pre-built Hitachi cross-compiler with several gnu utilities running under (...)

| | compiling the kernel winLegOS
|

Hi there. I've an old notebook (libretto 70ct) and of course not too much space on disk. So I wonder if I can compile the kernel with winLegOS, due to the fact that cygwin consumes a lot of space. If that's not possible, should I have to add some (...) (22 years ago, 2-Apr-03, to lugnet.robotics.rcx.legos)

(...) You might be able to use the Hitachi pre-built cross compiler for this. Ed (22 years ago, 2-Apr-03, to lugnet.robotics.rcx.legos)

(...) You can run Cygwin setup in a "Download from internet" mode, then take the files home, and run it in "Install from local directory" mode.

| | getting BrickOS through slow connection

My son and I have been looking BrickOS but one sticking point is that we have a slow connection at home which makes getting large packages hard. In such cases, I just download the files at work and burn the files into CD-RW and bring them home. Is (...) (22 years ago, 1-Apr-03, to lugnet.robotics.rcx.legos)

(...) The problem is that the upper memory area (0xf000-0xf800) is connected to both RAM and motor output. Every byte written here is also interpreted as motor command. The latest CVS version of BrickOS has fixed this (this memory is written only (...) (22 years ago, 2-Apr-03, to lugnet.robotics.rcx.legos)

(...) well, the RCX only has 32Kbyte of memory of wich half is used by brickOs the remaining half should fit you user programm and all runtime stacks and heaps, so allocating 40*40*2Bytes(the minimum for a pointer in an 32Kbyte adresspace) will need (...)
