SDRAM MT48LC16M16A2TG7E Example for evk1105 Documentation

Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the SDRAMC on EBI driver.

This example demonstrates how to use the SDRAMC on EBI driver with the onboard SDRAM. It initializes the SDRAM, tests it and then returns the number of errors found.

To use this code in your own application, make a pointer to the base address of the SDRAM and access it like you would normally access a memory-mapped device.
