Introduction

This is the same application as Optiflash OCRAM Benchmark, however, target functions are kept in external flash and smart placement enabled (Smart Placement). 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).
