Coreboot and FSP are not as easy to understand as you can see. I also
would suggest that you seek assistance from either Sage (who has good
experience that I understand serves the USA and Europe markets and
contributed the current Coreboot+FSP code) or perhaps a company in Asia
such as Zien Solutions (of Vietnam). There are a number of issues that
you are failing to understand:
1) As stated, the first serial port is actually connected to a
USB->Serial converter and delivered out of the microUSB connector on the
CRB.
2) You need to configure the FSP with Intels program to create a ROMable
image and not use the .fd file directly.
3) BayleyBay needs to be configured for non-ECC RAM whereas Bakersport
needs to be configured for ECC.
4) You don't necessarily need the TXE security module, but you could
very well cause problems if it is partially overwritten. Best is to
create a correct 8MB image to flash that has the proper Intel Firmware
Description block at the beginning.

First, the serial ports: The serial console is on the first serial port on the
micro-USB connection.
The 0x0000 on the post code display means that it's not actually starting to
boot - it's probably hanging in the TXE. There are known issues with upgrading
to coreboot from some of the bayleybay roms. I thought Intel was going to
document that, but I don't know if they did.
The Gold 2 FSP doesn't support D0 parts, so if you have a D0, you need the Gold
3. Also, the FSP is targeted at the embedded sku Baytrail-I. It might work
with M/D parts, I haven't tested that.
Assuming all that is ok, you probably need to start from a different rom. It
might be failing because of the TXE security. You'll probably need to talk to
your Intel contact to get that update.
Finally, if this is not a personal project, you might be interested in
contacting Sage and look at purchasing a BSP to get up and running. Either
way, let us know whether you make progress or need more help.

Hi Experts,
I am trying to boot BayleyBay CRB Rev 3 using coreboot and have no success so
far. I have serial port (DB9) connected and using 115200 Baud Rate. No message
comes on serial at all. Here is the procedure I followed.
1. Pulled latest coreboot from git.
2. Pulled following from BAY_TRAIL_FSP_KIT. The reason for doing it is that
BAYTRAIL_FSP.fd is not in git and .config refers to it. Also .config refers to
../intel/cpu/baytrail/microcode
a) created intel directory parallel to coreboot and copied
BAYTRAIL_FSP_GOLD_002_10-JANUARY-2014.fd in to
intel/fsp/baytrail/BAYTRAIL_FSP.fd
b) Copied *.h from Microcode folder in the kit to
intel/cpu/baytrail/microcode.
3. Configured the coreboot for mainboard as intel bayleybay. My .config is
attached.
4. Build Coreboot. Below is the prints from cbfstool.
cmos_layout.bin 0x0 cmos_layout 1132
fallback/romstage 0x4c0 stage 27813
fallback/ramstage 0x71c0 stage 67431
fallback/payload 0x17980 payload 268859
config 0x59400 raw 4363
(empty) 0x5a540 null 744088
cpu_microcode_blob.bin 0x110000 microcode 104448
(empty) 0x129840 null 157528
mrc.cache 0x14ffc0 (unknown) 65536
(empty) 0x160000 null 393112
fsp.bin 0x1bffc0 (unknown) 229376
(empty) 0x1f8000 null 31640
5. Flashed the coreboot.rom in upper 2MB (0X0600000-0x07FFFFF)
6. Reboot the board
7. Nothing comes on Serial Console (DB9). Also tried to connect Micro usb cable
which detects two serial ports but no output to any of them as well.
8. Before flashing coreboot.rom, 4 digit display was displaying something on
two digits and rest two were zero. Now all 4 digits stays at zeros.
Looking for help to get at least serial working so that I can get some logs to
debug it. I do not have copy of original BIOS that was there in Flash and
forgot to make a copy using programmer though I ensured that I only touch upper
2MB. I am stuck and have no logs to debug it.
Thanks in advance.
