Hello Naveen,
You should use the "MemDownCh0Dimm0SpdPtr" to point to a buffer containing the SPD data and set MemDownEnable" to 1.

Does this mean that there is a way in FSP to define custom settings(configs) for DIMMs? In the FSP integration guide for BroadwellDE (https://github.com/IntelFsp/FSP/tree/master/BroadwellDEFspBinPkg/Docs) I don't see any relevant data member where we could define pointer to custom SPD settings or pass individual DIMMs configurations.
there is the memory-down option. It seems undocumented if that does more than switching from on-DIMM SPDs to SPD files. Maybe it's worth a try. If that doesn't work out, you can always overwrite the SPDs on your DIMM's EEPROMs. Always keep a backup, though.
Hope that helps, Nico _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-leave@coreboot.org
