I assume you have left out SPD eeproms from BOM, so have you already
created and double-checked the SPD files? We have some boards in the
tree doing that already.

I hope to upstream DB-FT3b-LC board sources to coreboot.org, possibly
next week. That may or may not help You further.

Do you have PI build with raminit logging enabled?

Betreff: AW: [coreboot] AGESA PI for Olivehill+

I have SPD EEPROM on board. File is checked. But I think required DDR3 seed values are different between memory down star topology and SODIMM DDR3 modules in fly by topology. But in binary Pi  I see no way to change values. The only solution I see is to recompile AGESA and create a custom binary Pi. I can do this but is there anyone who has experience doing this way for coreboot?

Regards,
Wolfgang
