If we figure out why we see the device id of 0x0000 for the SOC
transaction router, I'd really like to understand that. I had initially
thought it was a B0 vs B3 issue, but I've heard from people that it
happens on the B3 silicon as well.
Currently if the device id comes up as 0, the northcluster code won't
get run, and the memory tables won't get generated correctly. A
fix/hack/workaround for this is to add this code to northcluster.c:
static const struct pci_driver nc_driver_b0 __pci_driver = {
.ops = &nc_ops,
.vendor = PCI_VENDOR_ID_INTEL,
.device = 0x0000, // for the B0 Supersku chips
};
This code was written when we thought it was a B0 vs B3 issue, thus the
names and comment.

Oh - what do you mean by the Sean?
I am still trying to understand why for two identical CPUID/Stepping
E3815s, with the same 8BM flash image, I get different PCI device ids
for the Soc Transaction Router ( 0000 rather than 0f00 ) and Video (
0031 rather than 0f00 ). Is this related?
I’ve asked Intel Premier Support but heard nothing back yet. Still
puzzled :o)
Mike.

PCI ids will be different. Plus some devices may be disabled.

As Mike mentioned earlier, you need the TXE ( located in top 6MB )
from BYT-I_SEC_DUAL_BOOT_PV_GOLD.
The TXE from the BIOS’s you mentioned don’t work with coreboot. I ran
into the same issue as you.
Alternatively you can erase the top 6MB to start in non-descriptor
mode. I don’t think this matters much for coreboot’s startup process,
but could be wrong.

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,

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

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
