Re: Elf debugging

[maybedoo <maybedoo at gmx dot de>]

Hmm it's strange that i've no debug information in elfboot.c?

Here is the ls from the src directory:

may@debian:~/coreboot/coreboot-v2/src/boot$ ls
Config.lb  elfboot.c  filo.c  hardwaremain.c  selfboot.c


Problem is that I need elfboot.c for a breakpoint.

Thanks for your help Paul with readelf. Didn't know that and how to use it.

Regards,

May
