My 550 won't boot without the DIMM in, so it sounds like it's not recognising the embedded memory.
OK. That is a good data point. However, I don't know from what code base that original wrapper was built from in order to debug further. Did you save the original rom image that your device was shipped with? I'd be curious to know if that matches the one found in the blobs repo.

Did someone change the SPD eeprom address notation in pei_data from 7-bit to 8-bit addresses? samsung/lumpy/romstage.c : .spd_addresses = { 0x50, 0x00,0xf0,0x00 }, google/stout/romstage.c : spd_addresses: { 0xA0, 0x00,0xA4,0x00 },
The 0xf0 handles the soldered down memory. I was looking at the 0x50 address as well, but I think that is correct (I'm looking at code that I think is the wrapper that you guys are using). I could be wrong though.
