Problem in linker file of Comic compiler for the .data and .bss sections

[ahmedfouda]

I'm using cosmic compiler. For S12x micro controller.

In the linker file if I set the following

+seg .data       -b 0x2110 -o 0x2110 -m 0x1EF0  -n .data
+seg .bss                                       -n .bss

The System works fine but If I change it to

+seg .data       -b 0xFE000-o 0x2110 -m 0x1EF0  -n .data
+seg .bss                                       -n .bss

The system doesn't work.

The only difference is that in the second case I put the global address, Do you have any idea what is the problem.

I need to use the second option due to some constraints within my application.

It would be best if you could provide info on how other segmets are configured.

For example, where is your stack? Why did you define your data with maximum size of 0x1EF0?

I believe the problem is that the physical and logical addresses don't match.

Try this:

+seg .data       -b 0xFE000 -o 0x2000 -m 0x1EF0  -n .data
+seg .bss        -a.data -n .bss
