[coreboot] latest baytrail fsp on CRB

[Wen Wang]

I went back to the commit (Martin's commit
d75800c7f2476bee243cc22255acb54d6676d4bc  back in late May) that seems work
for a few people on the list. I also thought it was working better for me
too as I was observing coreboot and fsp booting until it failed at SeaBIOS.
It turned out I had a pilot error flashing the image. I thought I flashed
the top 2M of the flash, but my script accidentally erased the bottom 6M.
Surprisingly it booted quite far.  Anyhow, after I corrected my script today
(flashing only the top 2M, leaving rest from BIOS). Nothing happens, port 80
remains 0, no console output.  Here is cbfstool print, my config file is
attached to an earlier post,

Could it be my BIOS issue? I tried both 64 and 32-bit BIOS from
540469_540469_BYT_l_66_41_ReleasePackage and
543844_543844_BYTI_080_011_ReleasePackage. None of them works with my
coreboot build. . Can somebody please share the working BIOS version?

 

Thanks,

 

Wen

Use the one that came with your board, or get the latest From the IBL. I
forget the document number but the file is called
byt-i_sec_dual_boot_pv_gold

Hi all,

 

Has anybody been able to boot Bayley Bay CRB with the latest coreboot source
from the git tree?   We have a Bayley Bay CRB (E3827, B3). With coreboot
Baytrail fsp support pulled from about two weeks ago and some help from
Martin, I was able to see coreboot booting and fsp loaded, but was having
issues with SeaBIOS.  I pulled latest source tree this morning and found out
it does not boot any more on my board. Port 80 stuck at code 0x43, no
console output. 

 

Here are my steps:

1.       Build coreboot toolchain.

2.       Build coreboot.rom using fsp and microcode from BAY_TRAIL_FSP_KIT
downloaded from Intel fsp site.

3.       Flash coreboot.rom to top 2M of the 8M flash.

 

I was getting the usage information here and there from the discussion
threads and perhaps I missed something? It would be great if somebody could
post the detailed procedure.

 

Thanks!

 

Wen
