Introduction

This example demonstrates the usage of the SDL DSS MAILBOX module. The example shows how to setup and use the ECC BUS Safety Diagnostic operation. Shows the generation of SEC and DED error on DSS MAILBOX ECC Aggregator.

Use Cases

Use Case	Description
UC-1	Single bit error injection on DSS_MAILBOX.
UC-2	Double bit error injection on DSS_MAILBOX.

Supported Combinations

Parameter	Value
CPU + OS	c66ss0 nortos
Toolchain	ti-c6000
Board	am273x-evm
Example folder	examples/sdl/ecc/sdl_dss_mailbox/

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
