I'm using a AT32UC3B0256 microcontroller in combination with AVR32Studio 2.6 and I wouuld like to please a constant variable at a fixed address ( e.g. at position 0x80799999) at the end of the flash.

const int variable __attribute__((section(????))) = 1234;

Any ideas?

In Program use

const int variable __attribute__((section(".varaddress"))) = 1234;

and in your linker script add this flag:

-wl,--section-start=.varaddress=0x80799999

Also you can check Memory Sections in AVR
