Nios II address range problem

Hi everybody,

I am using SOPC to built avalon interface for my custom external logic.i have selected NiosII as master and my custom logic as slave.Using new component Wizard, I have added signal and interface. In the interface i have selected avalon slave,i got an error before generation.

cpu_0:nois ii instruction master cannot address memories over 2^32.

cpu_0:nois ii data master cannot address memories over 2^32.

My data width is 32 but still getting error.

I have tried auto-assign base address and manually edit addresses also but no effect.what base address should i specify for my device.

Have anybody experienced this problem.
