Memory not recognized

[sonnius]

Hello,

I've built coreboot for the polestar motherboard but I seem to have no luck (D1 production CPU).

1. I've followed the instructions on the coreboot website for the polestar
2. I've followed the instructions on the github issue (How to build/install? #6)
3. I tried a binary build erying-2405-d1.rom

In all cases I run into the same issue where the memory is not detected at all.

I've tried swapping memory but this doesn't seem to help either.
I tried:
2 x 16G dual ranked (Erying branded)
2 x 32G dual ranked Gskill

Both these configurations work without any problem with the original firmware both in default and XMP settings.

Is there anything I can do to debug this?

Sounds like i7 might use a different board revision with different SPD addresses?
Try messing with SPD addresses from 0x50 to 0x54.
https://github.com/coreboot/coreboot/blob/main/src/mainboard/erying/tgl/romstage_fsp_params.c#L14-L15

Both boards I have (D0/D1 i9) work just fine with any RAM sticks I throw at them (Kingston 2x8GB, Patriot 2x16GB).
