# Introduction

This is the same application as Optiflash OCRAM Benchmark, however, target functions are kept in external flash. The effect of it is seen in the execution time.

# Steps to Run the Example

## Building the application

- When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
- When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)

## Running the application

Flash the application binary to the device, follow the steps mentioned here (see Flash a Hello World example).
