Are you using DDR2 HP component without SOPC? Anyways, are you taking care of feedback signals from controller like rdata_valid and wdata_req signals? I guess DDR2's latency will come into picture and you will not be able to write or read anything immediately you need to wait for its latency period, I guess you should be able to read/write single data by controlling DDR2 HP component using feedback signals given.
