Thanks Joerg for your quick answer.

I tried adding "-save-temps" to the compiler flags, but it didn't help.
It just saved the .s files in the local directory where I have all the
source files with the names of my project files.

However, following that line of reasoning I continued a bit more of
exploration of the output of "objdump -g", and found what I think are 
hints that suggest that the /tmp files were recorded by avr-libc 
libraries, not by the Ethernut project (see the end of this mail for 
more detailed info about the output of objdump -g).

Just to be sure and make things easier I just got the first example from 
the avr-libc 
(http://www.nongnu.org/avr-libc/user-manual/group__demo__project.html)
Here we also get references to temporary unexisting files:
----------------------
address@hidden:~/ethernut-4.2.1/nutapp/test1$ avr-objdump -g demo.elf | 
grep /tmp
/tmp/ccZFY2vd.s:
------------------------
However, for the case of the simple project I _can_ use avr-gdb quite 
nicely (using AVRJTAGICE mkII + avarice), while for the Ethernut project 
I just can't.

So somehow it now seems to me that the problem of not finding the 
temporary files might not be the real issue that makes it impossible for 
me to debug using avr-gdb in Linux. I am puzzled...

I will continue with this issue. Any more ideas?

Tanks,
José



Now, here is part of the output of "avr-objdump -g" where the temporary 
files are found.
