The HLDC-DDR4-4G-A seems to be mentioned only with Stratix10 dev board.
Does it also work with the DK-DEV-10AX115S-A board?
Hi, All dev kit come with it's dedicated HiLo daughter card. You should use the dedicated card instead of other dev kit daughter card. However, to confirm either it is compatible or not, you can check both dev kit schematic, under externam memory interface connector map. See if the mapping is same between both board, if they are same, it should conclude as compatible.
