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,
[wenwang@localhost coreboot]$ build/cbfstool build/coreboot.rom print

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

Also what should I do for flash descriptor?
Thanks,

Can you post your coreboot .config file?

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
