Hi,

The 256Mbyte address range limitation is only for instruction masters.

In SOPC builder make sure your non instruction components are not connected to the CPU instruction master interface and that all of your instruction master parts are grouped inside the 256Mbyte limit.

SOPC builder will show you (and allow you to edit) what is connected to the instruction master. From the menu

View--> show master connections.

Clicking on the dot next to your device will change whether it is connected or not. Hollow = not connected. Solid = connected.
