printf

[Franzi Edo.]

Hi,
I would like to implement the "printf" function on my target.  
Accordingly with the documentation I found it seems that it is enough  
to write some low level routine such "fstat, sbrk, istty, ... read,  
write". So, I implement these functions and I can monitor that fstat,  
sbrk and isatty are called during the printf. However, the write is  
never called. Do I have initialise some I/O table or tuffs like this  
to make operational my printf? Any ideas?

I use gcc-4.1.0, cpu32 target

Regards E. Franzi
