Introduction

This example demonstrates the usage of the SDL MSS L2 module. The example shows how to setup and use the ECC Safety Diagnostic operation. Shows the generation of SEC and DED error on MSS L2 ECC Aggregator.

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
Toolchain	ti-arm-clang
Board	am273x-evm
Example folder	examples/sdl/ecc/sdl_ecc_mss_l2/

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

Sample Output

Shown below is a sample output when the application is run,

ECC Example Application
 
ECC UC-1 and UC-2 Test 
 
ECC_Test_init: Initialize of MSS L2 ECC Memory is complete 
 
ECC_Test_init: MSS L2 ECC initialization is completed 
 
ESM_Test_init: Init MSS L2 RAMB single bit ESM complete 
 
MSS L2 RAMB Single bit error inject: starting 
 
ESM Call back function called : instType 0x1, grpChannel 0x1, intSrc 0x12 
 
Take action 
 
ECC Error Call back function called : eccMemType 2, errorSrc 0x1, ramId 1, bitErrorOffset 0x00000001, bitErrorGroup 0
 
MSS L2 RAMB Single bit error inject at pErrMem = 0x10280000 and the value of pErrMem is 0x00000000 :test complete
 
Waiting for ESM Interrupt
 
UC-1: Injected 1-bit error and got ESM Interrupt 
 
ESM_Test_init: Init MSS L2 RAMB single bit ESM complete 
 
MSS L2 RAMB Double bit error inject: starting 
 
ESM Call back function called : instType 0x1, grpChannel 0x1, intSrc 0x11 
 
Take action 
 
ECC Error Call back function called : eccMemType 2, errorSrc 0x2, ramId 1, bitErrorOffset 0x00000000, bitErrorGroup 0
 
MSS L2 RAMB Double bit error inject: pErrMem fixed location = 0x10280000 once test complete: the value of pErrMem is 0x00012002
 
Waiting for ESM Interrupt 
 
UC-2: Injected 2-bit error and got ESM Interrupt
 
All tests have passed.
