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

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?

Kyösti
