what about getting the address of the reset vector and start debugging from
there? Just look in the map-file. I'm not familiar with Eclipse but at least
it must be possible to set breakpoints on (HW)addresses. 

But let us stay focussed on the interesting discussion of how the HW
initialisation can be improved in NutOS. Calling code before main: nothing
wrong about that IMHO. Cannot think of another way to get your int i=5; done
runtime. In NutOS quite a lot of initialisation is done before calling
main(). Debugging has never been a problem (for me).
