Hi,

I'm interested in using a 1GB sodimm w/ a cycloneIII, however, in SOPC builder when trying to use one of the built in presets for the Micron MT9HTF12872AY-800E1 1GB sodimm I get the following error:

Error: cpu_0: Nios II Instruction Master cannot address memories over 2^32

Error: cpu_0: Nios II Data Master cannot address memories over 2^32

Error: cpu_0: Memory map cannot fit within the addressable memory space of the Nios II Data Master which is restricted to 31 address bits

Has anyone successfully implemented a 1GB sodimm? If so, what was used?
