Hi Jose, All,
According to the following outputs, it seems my target has SPD EEPROM.
If I understand correctly from your reply, I should modify only:
DRAM Type: DDR3
DRAM Speed: 1333 MT/s
DIMM 0 Enable: Enabled
DIMM 1 Enable: Disabled
DIMM_DWidth: x8
DIMM_Density: ??? (Default is 2Gbit)
DIMM_BusWidth: 64
DIMM_Sides: 1 Ranks
Am I right ?
I tried booting the target with the modified FSP and got post code : 0xCE
There is nothing on the 232 console.
There is no such post code in coreboot code.
Is it possible that FSP is sending post code ?
How can I proceed from here?
Thank you very much,
Zvika
