Introduction

This example demonstrates the usage of the SDL R5F BTCM module. The example shows how to setup and use the ECC Safety Diagnostic operation. Shows the generation of SEC and DED error on R5F BTCM 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_r5_btcm/

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: Exception init complete 
 
ECC_Test_init: Initialize of R5FSS0 CORE0 ECC Memory is complete 
 
ESM_Test_init: Init MSS ESM complete 
 
ECC_Test_init: R5FSS0 CORE0 ECC initialization is completed 
 
R5FSS0 CORE0 BTCM Single bit error inject: starting 
 
ESM Call back function called : instType 0x1, grpChannel 0x1, intSrc 0x2a 
 
Take action 
 
ECC Error Call back function called : eccMemType 49783896, errorSrc 0x400, ramId 270978723, bitErrorOffset 0x1026aa054fea7fca, bitErrorGroup 0
 
R5FSS0 CORE0 BTCM Single bit error inject at pErrMem = 0x00080010 and the value of pErrMem is 0x00080000 :test complete
 
Waiting for ESM Interrupt 
 
UC-1: Injected 1-bit error and got ESM Interrupt
 
R5FSS0 CORE0 BTCM Double bit error inject: starting 
 
R5FSS0 CORE0 BTCM Double bit error inject: pErrMem fixed location = 0x00080010 once test complete: the value of pErrMem is 0x00080000
 
Waiting for ESM Interrupt 
 
UC-2: Injected 2-bit error and ESM Interrupt not occured
 
All tests have passed.
