Programming a.out vs a.elf

Started by "=?U...@gmail.com [msp430]" May 22, 2017
Hi,

I'm working with msp430-gcc and I can program a.out using mspdebug fine
into my target.

Is there a benefit in generating and programming a.elf to the target?

You seem to be confusing the default file name with the file format. The
file is in elf format and you can name it anything you like.

Sorry I was not clear. I'm referring to the format rather than the filename.

I am able to program *.out and *.elf with mspdebug

What is the difference?

I believe that *.elf can be stripped (symbols) for production runs.

Anything else I'm missing?

Thanks.

How are your getting a.out format from gcc?

elf32-big plugin srec symbolsrec verilog tekhex binary ihex

Pardon, my ignorance. The default output file generated by gcc is named
a.out but it is elf format :-)
