Keywords: BSB, 7.0, uBlaze, MMU

When I use Base System Builder (BSB) to build a project on a Spartan-3 series device, the options on the MMU tab are always gray. How can I enable the MMU?

Solution

For a Spartan-3 series device, area optimization is on (by default) and the MMU is not available in an area-optimized MicroBlaze.

1. Right-click on the MicroBlaze instance in the design.
2. Select "Configure IP".
3. Select the "Instructions" tab.
4. Deselect the Optimization box.

You should now have various options available to select under the MMU tab.
