Post code 0x0000 could also be the case the you do not have the latest microcode patches. Please double check.

Hi Sean,
- This is not for a real project and we are trying to understand FSP
interaction with coreboot to look at feasibility for considering coreboot in our future projects. Unfortunately I do not have board documentation so was not able to determine which one is serial port 0 though I know that port 0 is specified in coreboot config. That was the reason I was trying on all 3 available ports. 2. I am not using .fd directly. I believe that FSP need to be included in bootloader (coreboot in this case) and we are providing path to coreboot so that it can be included in coreboot. In my original post I only said that I copied .fd to a path expected by coreboot configuration. May I know how did you conclude that I am using it directly? May be that can give me some pointer. 3. I had checked the bsf file in the FSP kit with BCT tool and it is configured for non-ECC RAM, so I believe that no change is required in .fd. Am I wrong? 4. Yes, I agree that there is no documentation available on how to create entire 8MB binary with Firmware Description, TXE, coreboot etc so for safe route I only touched upper 2 MB as recommended in one of the initial commit for baytrail FSP integration and some posts related to similar discussion.

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:
- 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.
- Pulled latest coreboot from git.
- 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.
