Introduction

This example takes an aggregator index as input from the user and performs single bit error test for the corresponding aggregator. It involves the following steps:

• Setup of an ESM application callback to receive Single Error Correction (SEC) and setup of ECC Aggregators in general
• Triggering of ECC events for all the RAM IDs, including Interconnect type and Wrapper type
• Printing out error information within the ECC callback upon reception of ECC events

Aggregators Supported

The following aggregators can be tested using this example.

Steps to Run the Example

• 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)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
