RE: [avr-gcc-list] Specification of AVR ELF format?

[Weddington, Eric]

Hi Wim,

I don't think that there is any documentation on the ELF format, other than 
what is in the source code (and patches). Certainly any documentation in this 
area would be welcome.

What kind of tool are you planning on writing?
