Hi ,
Greetings .
We are working on intel c508 intel denverton board . It has a soldered 4GB DDR4 connected to Channel 0 , Dimm 0 .
Below are the changes made :
1. We are using harcuvar board as a reference . I have selected * Enable Memory down option in menu config
2. Added spd values file in src/mainboard/intel/harcuvar/spd/spd_filename.hex
3. spd.bn getting generated in CBFS
FMAP REGION: COREBOOT Name Offset Type Size Comp cbfs master header 0x0 cbfs header 32 none fallback/romstage 0x80 stage 42084 none cpu_microcode_blob.bin 0xa580 microcode 11264 none fallback/ramstage 0xd200 stage 70701 none config 0x1e680 raw 1227 none revision 0x1ebc0 raw 691 none spd.bin 0x1eec0 spd 512 none fallback/dsdt.aml 0x1f100 raw 7791 none fallback/postcar 0x20fc0 stage 21832 none fallback/payload 0x26540 simple elf 656810 none (empty) 0xc6b40 null 6656600 none fspt.bin 0x71fdc0 fsp 4096 none (empty) 0x720e00 null 3992 none fspm.bin 0x721dc0 fsp 589824 none (empty) 0x7b1e00 null 3992 none fsps.bin 0x7b2dc0 fsp 102400 none (empty) 0x7cbe00 null 114584 none bootblock 0x7e7dc0 bootblock 32768 none
4. Tried giving 256 and 512 values
CONFIG_DIMM_SPD_SIZE=256
We are using Fitc tool to generate full fw image,getting below error and got stuck after loading the build

Any help on this is highly appreciated .
Thanks,
