How to setup a correct linker file

Hi.

I'm working on a larger project, which is split into a subset of libraries.

As the code grew the more warnings appeared after linking (Section located outside class area), which resulted in a strange behaviour. I.e. Function pointers in structures pointed to the wrong functions, functions weren't properly executed, etc.

So I tried to modify the concerning linker file to take full advantage of the provided hardware (Infineon XC164, 256KB RAM, 128 KB Flash, 6KB On-Chip-RAM). But without any luck so far.

Are there any rules to properly setup a library file? When do I have to use which class?

Here is my current linker file:

CLASSES (ICONST(0x000200-0x003FFF),
         CCONST(0x000300-0x003FFF),
         ICODE (0x000200-0x003FFF),
         NCODE (0x000200-0x003FFF),
         NCONST(0x000200-0x003FFF),
         FCODE (0x000200-0x007FFF, 0x010000-0x02FFFF),
         FCONST(0x000200-0x007FFF, 0x010000-0x02FFFF),
         HCONST(0x000200-0x007FFF, 0x010000-0x02FFFF),
         XCONST(0x000200-0x007FFF, 0x010000-0x02FFFF),
         LCODE(0xC00000-0xC1FFFF),

         0x03FE00-0x03FFFF)     ; Monitor: Code + Data RAM1 (CS0)

The library and application code does not care about any classes when declaring variables. I'm just using const for read-only variables. Does this probably cause these problems?

Thanks for your help in advance,
Axel.
