New subject: post_code to text file

16 Dec 2016


      Thank you for the hint, I have 'installed' cbmem by making tthe appropriate menuconfig changes and in util/cbmem "$make LD_FLAGS=-static". Though (and I apologize for my nieve-ness) how exactly to I use the "$ cbmem -c" command, specifically wher exactly in boot/start up process should I call it- I cant call it from the OS, and I haven't been able to find anything on google relating to how to access coreboot userspace...

cbmem, in util/cbmem/, should be what you are looking for.

Hello All,
I was wondering if it would be possible to add a few lines in the post_code
method so it also writes all the codes to a text file and then keep that
text file around so it could be read once the system is running - for
debugging purposes because a post_code reader is currently unavailable to
me. I know that the BIOS handles the post codes and my chosen BIOS is
coreboot and I have added just a couple lines to the post code method right
after mainboard_post() is called in order to print the codes to a file in /
as well. But I don't have any idea how to pass a small text file along from
coreboot up to yocto jethro during boot - is this even possible?
Any comments, thoughts, ideas, guidance  would be greatly appriciated. Thank
you.
