Introduction

The example shows how to setup and use the ECC Safety Diagnostic operation on d-tag cache momory of R5F core. Shows the generation of SEC error on R5F ECC Aggregator for DTAG cache moemories.

Use Cases

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

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
	r5fss1-0 nortos
Toolchain	ti-arm-clang
Board	am263px-cc
Example folder	examples/sdl/ecc/sdl_ecc_r5_d-tag/

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
