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.
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".
