SDRAM used on Bemicro eval board

I am trying to test the new Bemicro eval board purchased from Arrow.

(Note: this is the 2nd generation USB eval board that has temperature sensor on it). According to the schematic, the board has a DDR memory -- Micron

MT46H32M16LFBF-5 installed. I would like to include the memory chip in the SOPC builder but for some reason I could not find any memory controller that matched the part library in SOPC . I am using Quartus Ver 9.1 . Does any body have any idea what I should use from the memory component listing? the accompanied reference sample design did not use the memory al all.

Thanks in advance

JIMMY

    I just started fighting this problem too. Probably you have on older Bemicro version with CIII. I have a Bemicro-SDK with Cyclone IV that requires Quartus 10. But my problem is the same as yours- there is a useless overprotected example of Mobile DDR IP that does not work at all, and I am trying to use Altera's DDR SDRAM Controller from SOPC Buider. It looks like this is not an easy task and what I've got so far is:

    "Warning: cpu_0: The address range of the slaves connected to the Nios II instruction masters exceeds 28 bits. Attempts to call functions across 28-bit boundaries is not supported by GCC and will result in linker errors. "

    IS this really possible?
