Hi Andrey,
Even I tried flashing with IFWI .bin file released by Intel, the board still doesn't boot.
ah, I think I misunderstood you. You were saying even stock Intel-provided image didn't work. If that is the case yes, probably flashing is the issue. Can you try to read back from flash image right after flashing? Then compare it to the file you wanted to flash. This way you can tell if flashing works.

Thanks Andrey, that was what I mean. I tried as your suggestion: flashed an 8 MB Intel-provided image, read back from SPI chip right after flashing, got a 16 MB file (since SPI chip is 16 MB size). The first 8 MB of 2 files are exactly the same. So, flashing should work fine.
I also went through coreboot mailing list and saw this thread: https://www.coreboot.org/pipermail/coreboot/2017-February/083413.html The guy here got the same problem with me:
- Currently:*
- DS6B1 : Green ON*
- DS6B2 : Green ON*
- DS2C1 : OFF*
*DS3B1 : RED ON*
- No Output on serial console or HDMI. *
And you commented:
Red light is never a good sign. Do you have a way to know if PLTRST# has
been de-asserted?
Another thing is that when you stitch with FIT you need to turn off boot
guard completely. I suspect you have it on and that makes CSE to check signatures. Please check that in Platform protection -> Bootguard configuration it is set to "bootguard profile 0 - legacy". Then try restitching fit image and rebuilding coreboot again.

In my case: - PLTRST# has not been de-asserted. I plugged a PostCode display module in the CRB and RST LED is always Green ON. - Bootguard configuration is already set to "bootguard profile 0 - legacy".
Could you please give me further advice? Thanks a lot.
