4.1.5. Memory Management Unit Settings

The Nios II/f core offers a memory management unit (MMU) to support full-featured operating systems. Turning on Include MMU includes the Nios II MMU in your Nios II hardware system.
Note: Do not include an MMU in your Nios II system unless your operating system requires it. The MMU is only useful with software that takes advantage of it. Many Nios II systems involve simpler system software, such as Altera® HAL or MicroC/OS-II. Such software is unlikely to function correctly with an MMU-based Nios II processor.
