# MMZ Demo

## Overview

This sample demonstrates common MMZ memory-management flows.

## Source Location

```bash
src/rtsmart/examples/mpp/sample_mmz
```

## Build Method

Enable `Enable Build sample_mmz` in `make menuconfig`, then rebuild the firmware.

## Run Example

```bash
cd /sdcard/app/examples/mpp
./sample_mmz.elf
```

## Notes

The sample covers:

- allocate cached and non-cached MMZ memory
- release MMZ memory
- query physical information from a virtual address
- flush cache

It prints `sample mmz test success` on success, or an error summary if a step fails.
