Most probably, your gcc is not compiled with dwarf2 support. You have to supply 
the
--with-dwarf2 configure switch. In order to find it out compile an arbitrary 
source file using the switches "-S -g" the generated assembler file should have 
lots of dwarf2 output
Information.

Bjoern.

Betreff: [avr-gcc-list] Debugging gcc output with AVR studio

Hi, 
   I've just downloaded the latest and greatest WinAVR 20050214 and AVR
Studio (4.12 Build 452) 

I'm generating a .elf file with and trying to debug this in AVR studio
(using STK500)  When I compile with the -gdwarf-2, it does not seem to
generate any debug information. A dwarfdump shows nothing. Compiling
with a -gstabs and the debug information is there (an see it with avr-
objdump)

Is the gcc compiled using --with-dwarf2?? If so any idea what I am
doing wrong??

Actually I came to this after trying to use avarice (complained about
innappropriate ioctl ). Avrdude totally crashes. Looking at both these
things with portmon it appears that a couple of the commands being
issued are not recognised be the STK500 firmware version 4, and version
2.01.

I think that generating an elf file with debug information is the
correct way to go from a web search. Am I correct in this assumption??

Regards
