Hello Catalin,
The combination large memory model and stack-auto is not built (and
tested) in the sdcc distributions. So there are no libraries for it by
default. You can create them yourself or you might be able to find them on
the web (contiki site?). To create them you can modify device/lib/Makefile
if you build from source.
Greets,
Maarten
