Introduction

This example demonstrates basic read write to the eMMC Card via DMA. The MMC instance and the media connected to it are selectable via Sysconfig.

The example writes known data to a particular offset in the media and then reads it back. The read back data is then compared with the written known data.

When both the comparisons match, test result is passed otherwise failed.
