main() mapped over several flash pages

Hi all !

I am using Codewarrior 4.5 with a MC9S12XDP512CAL.

I ran into a problem after my Main() went too big. I get the following error:

Link Error: L1102 Out of allocation space in segment PAGE_F7 at adress 0xF78229

I looked at the map file and the main() is indeed to big for a single segment. but there are more than enough free segments.

I allready tryed the "allocation over segment boundries" options of the linker, but the problem stays the same.

Is there anything else i have to adjust to allow the allocation over segment boundries?

You should split main() into two or more smaller functions and call them from main(). You can't allocate functions over page window boundaries, code won't run.

Err... if you wrote your program as a single, 16kb large function, this one is the least of your problems...
