No copydown created for initialized object?

Question

I'm using codewarrior to compile for the HC12, and I have two 120 element arrays: score and dur. I have initialized them in the typical fashion: unsigned int score[120] = { ... }; When I try to compile it, however, I get a linker error that says "L1981: No copydown created for initialized object "score". Initialization data lost." I can't figure out what that means or how I can make it so it creates a copydown. Note that this program compiles and seems to set values fine when I place them into main(), but I need them to be global variables because they are accessed by an interrupt.

There are two likely reasons:

• Either you managed to declare this variable on the stack (bad idea) or in a memory segment that is too small to contain it. Consider placing large variables like these in dedicated RAM segments, by altering the .prm file.
• Or you have created a Codewarrior project with "minimal" startup code. If you do so you pick a non-standard setup where the initialization phase of objects with static storage duration is removed.
