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
