Thanks for the quick reply! I hacked a linker script. But the are so many options which could be the required one that i dont know which to use :( I'm a newbie in embedded programming so dont kill me for that. I've read the ld documentation twice.

------

MEMORY
{
  ram     : ORIGIN = 0x10000, LENGTH = 3M
}

SECTIONS
{
  .data  : {
 *(.data)
  } > ram
}

-----------

The system has 3 mb ram. Does LD use the 3M as an absolute value or origin + 3MB? (which then is illegal). Is origin the value i have to set? Or do i need to set one of the section parameters like AT?

Thanks for your great help
