first, I would like to thanks Joerg Wunsch for his patch to include elf to coff in the avr toolset (avrgcc).
I'm using WinAVR 2030312 release with the elfcoff patch.
I had a problem with the Avr Studio 3.53 (AS3) with the coff file done with avr-objdump: AS3 failed to load and give the error message "Unable to open source file" and "Error in Coff file !".
Using AVR Studio 4 the coff file is loaded, but in the Project, source tabs the name <build-in> appear as a source file name.
Others had the same problem.
After some tests, Joerg found the problem : this is his reply in the AVRfreaks.net forum. If other people have the same problem, they can
solve the problem following the instruction of Joerg.
