[En-Nut-Discussion] Ethernut 2.1 and AVR studio

[Jim Patchell]

Ah...this is something I can help you with, as I just went through this 
exersize just a few days ago.

First, how I solved the problems.  I looked in a make file for one of 
the applications to see what linker options were being used.  I then 
added those to the project.  Also, there are some compile time macros 
that need to be added as well.  I am thinking I should put a little doc 
together, just so I won't have to figure this out again the next time.

Also...it is important to use the correct version of WinAVR with a 
particular version of Ethernut.

Oh dear....getting late...hope this will help a bit...if you still can't 
figure it out (or maybe somebody else will be able to give you more 
specifics)...I can give you that info a bit later on...

-Jim
