Hi,

it think the SPD module type definitions for DDR4 SO-DIMM with ECC in the file include/ddr_spd.h are swapped:

#define DDR4_SPD_MODULETYPE_72B_SO_UDIMM (0x08)
#define DDR4_SPD_MODULETYPE_72B_SO_RDIMM (0x09)

According to JEDEC document SPD4.1.2.L-4, UDIMM is 0x9 and RDIMM is 0x8. Can someone verify this?

Regards,
Ralf
