Introduction

This example shows setup and usage of some ECC Aggregators for a few events in the Main domain. It shows the following:

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

The following use cases are implemented in this example:

Use Cases

Use Case	Description
UC-1	Single DED error on WKUP ESM for wrapper RAM ID type
UC-2	Single SEC error on Main ESM for wrapper RAM ID type
UC-3	Parity error injection on Main ESM for interconnect RAM ID type
UC-4	Single DED error on Main ESM for wrapper RAM ID type

Supported Combinations

Parameter	Value
CPU + OS	mcu-r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am62ax-sk
Example folder	examples/sdl/ecc/

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
