Andrey, It seems to me that it's stepping properly. The .extra tells nesc and gcc to compile without inlining and without optimizations, and generate dwarf-2 debug information with source paths in windows format.
It will not work under linux (because of the windows-style paths), and it won't work with gdb because dwarf-2 is only partly supported (whatever that means). I would be happy to hear back from you regarding your experience with debugging in AvrStudio, though.

This is very interesting. Thanks in advance! I'm using iris and micaz. I tried to use ddd in GNU/Linux and I am able to set breakpoints only at some lines in .nc that are be mapped from .nc to app.c and debug the application with JTAG. But with "step" ddd/gdb doesn't really process only 1 line of code but goes throw the calls (so it works as "next"). Will it be possible under Windows with AVRStudio to step properly throw the code? And is this possible to use your .extra with or without changes to debug/simulate under GNU/Linux?
