[avr-gcc-list] External memory mapping problem |

Hi All!
I have the following memory configuration for an ATMega103:
intenal RAM: $0060- $0FFF (4K)
free space for memory mapped devices: $1000- $7FFF
32K external RAM: $8000- $FFFF (32K)
- Does anybody knows how the linker script file should be modified (the 'data'
section I suppose) in order to tell the linker about the 36K of available SRAM?
- Is the linker capable to manage this type of configuration? I mean that can I
tell the linker to use for variables, etc. the SRAM from $0060-$0FFF and
$8000-$FFFF ?
I have seen somewhere on the net something like this in a source with a memory
mapped ethernet card, unfortunatly I can't find the code anymore.
Any help would be appreciated
Regards
Zoltan Molnar
