We would like to use LS1043A custom board with DDR4 in 16bit mode. Regarding this Please confirm the interface connections between LS1043A and DDR4 as per attached doc.
the diagram looks correct. MA14/MBG1 is used when x8 DDR4 DRAM chips are used (x8 has 4 bank groups). x16 DDR4 does not use the BG1 (it has two bank groups)
