Introduction

This example demonstrates the usage of the SDL R5F ATCM0 module. The example shows how to setup and use the ECC Safety Diagnostic operation. Shows the generation of SEC and DED error on R5F ATCM0 ECC Aggregator.

Use Cases

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

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am263x-cc
Example folder	examples/sdl/ecc/sdl_ecc_r5_atcm0/

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

Low Priority Interrupt Executed
 
Read data of SEC MSS_CTRL register is  0x0
 
Read data of SEC RAW MSS_CTRL register is 0x0
 
R5FSS0 CORE0 ATCM0 BANK0 Single bit error inject at pErrMem = 0x00000510 and the value of pErrMem is 0x00000000 :test complete
 
Waiting for ESM Interrupt
 
UC-2: Injected 1-bit error and got ESM Interrupt
 
All tests have passed.
