A vague guess: The compiler generates a call, which allows a 24 bit
offset only, but the distance between your flash code and the RAM
requires a larger offset.

To fix it immediately you may try the following hack:

1. Create a local copy of at91_efc.c in your app dir.
2. Compile it individually, adding the compile option -mlong-calls
3. Link the local at91_efc.o before linking libnutarch.a

Mh... right now I do not have the slightest idea how to solve this
generally.

I remember, that André Riesberg added the missing .ramfunc segment to
several linker scripts. Possibly he stumbled over the same problem and
already found a solution.

André? Are you listening?
