Hi innotronics,

There are two common ways of accomplishing what (I believe) you want:

1, access the structure via a pointer:
#define DEFSBASE  0x01010000
struct Defs *pDefs = (struct Defs *) DEFSBASE;
...
pDefs->Nr = <<whatever>>

or ...

2. put the structure in a named section ...
struct Defs  myDefs __attribute__ ((section (",defs")));
myDefs.Nr = <<whatever>>

... then locate the section where you want in your linker command file.
__defs_start = .;
    .defs :
    {
   *(.defs)
    }

Regards,
