Occasional Contributorburst read and write DDR2 using altmemphy
Device: EP4CE22F17C8
Memeory: Micron MT47H64M8CB-3
IP: altmemphy DDR2
local max Burst count = 64
Operation: 1 time burst write data -> 1 time burst read data
issue: when set local size = 2, it works fine.
when set local size = 16, we can not get data read out. (local_rdata_valid = low)
Please see attachment for project code.

May I know how do you change the local size?
Thanks,
