[En-Nut-Discussion] debugging ethernut apps

[Henrik Maier]

Hello Ernst,

I stopped "coffing" and since the advent of AVR studio 4.11, the 
ELF/dwarf-2 format seems to work reasonably well. The intermediate step 
to create a coff file is not needed any more.

I compiled the Nut/OS libs using the following flag for compiler and linker:

   -g3 -gdwarf-2

It put these flags into UserConf.mk.

Then I also compiled my apps using the same flags into an .elf file. 
Load this .elf file into AVRStudio and you can start source level 
debugging incl. Nut/Os routines.

The only draw back is that AVRStudio can't find main() by itself because 
Nut/OS overrides main.

Use the project wizard to load the elf file and to select the programmer.


Cheers

Henrik
