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.

The problem seems to come from the address bus, not the data bus. What is the size of the address bus on your component?
