Bill, I have found a few of my problems, which I will explain here: Long time ago, before I was subscribed to the mailing list, I also tried to make a m68k-coff crosscompiler, following http://sources.redhat.com/ml/crossgcc/2000-q2/msg00195.html. (please do read it, it will become clear very soon why my memory was so messed up). In that document, which is 'good' if u just want to learn about compilers or about m68k assembly language, the problem for the 'make'-errors was to change the gcc source-code itself. But it is not really the way to go when you want a 100% customizable compiler. It uses its own default bcc.ld which is for some specific board. And it's not possible to 'add' or replace it with an own linker-script. I have re-made the m68k-coff GCC using the steps laid out by your script. Now it is finally doing what I want it to do. But i'm still having little problems dividing the target's memory. For example: I have somewhere in my code : unsigned int rand1 = 0x34fb; and in my 'random' routine, it uses this number to make a new (pseudo) random number. When compiling, the linker puts rand1 in the 'rom1' section. But this doesn't work, because I have to update that 'seed' value every time I call my "random()" routine. (i want to make the LEDs flash random values). But I think this is a bit to be expected. The compiler/linker does not know my target, only some regions where to put certain things. To be sure, i would like to ask where the linker would put the following things : (all globals) unsigned int Rand1; (my guess is : .bss ??) unsigned int Rand2=0x34fb; (my guess is : .data ??) #define QUICC_REGS 0x0501000 volatile struct Quicc_regb* Quicc_register=(struct Quicc_regb*) QUICC_REGS; (my guess is : .data ??) So would you solve the problem with intialized variables that will be changed later in the program ? Kind regards, Jan ------ Want more information?
