RE: [avr-gcc-list] Win32 GCC, Elfcof and Astudio 3.53 or 4.02

AFAIK, *all* source files *must* be in the same directory as the COFF file, due to limitations with both the COFF file format and AStudio. The AVRGCC *freaks distro makefile tries to copy all files to the master direcory, but I have had problems getting this to work with AvrX (which I guess is what you are trying as well ;-) ).

I also suspect that ELFCOFF might have a problem generating a COFF file, which AStudio wil accept. No hard facts yet, but I'll dig a bit further down.

I've seen the endless RXC thing in AStudio 4 as well with AvrX. Seems not to be there, when AvrX is not used.

Does anyone have a *working* multi directory project using libraries
(your own, not libc) using either the avrfreaks distribution or the
"test2 release" avrgcc128 compiler that they can use astudio with the
resulting .cof file?

If so, could you share a few e-mails with me on how you have things
set up.  I can build, etc. But no matter what I do I cannot load a
.cof file into astudio with out a GPF somewhere.  I assume it is some
subtle configuration issue, so I would like to copy a working
configuration.

With the avrgcc128 distribution, I am, after a fashion, able to load
an Atmel OBJ file into Studio 4.02, but that simulator seems really
buggy (endless RXC interrupts even though no flags set...)  With the
avrfreaks distribution, I am able to do full .obj debugging using
Astudio 3.53  However, it would really be nice to be able to use .cof
files.




Thanks!
