[avr-gcc-list] Beta test for GNU binutils ELF->COFF converter

[Patrizio Zelotti]

Hi,

 

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.
