Part Number: RM57L843
Other Parts Discussed in Thread: HALCOGEN, , NOWECC

Hello,

I have added the safe Ti diagnostics library 2.4.0 as the procedure mentioned in the example of HALCOGEN 4.07.01,

Some tests are getting pass and some tests are getting fail,

Like,

1. EFuse Test is Getting stuck on EFUSE_SELF_TEST_STUCK_AT_ZERO, the following API produces negative result and stuck into while(1) loop

/* Run Stuck At Zero Test (param2=TRUE - Wait for complete) */
retVal = SL_SelfTest_EFuse(EFUSE_SELF_TEST_STUCK_AT_ZERO, TRUE, &config);
if(retVal == false){while(1);}Code

2. L2RAM ECC Check Enable is getting stuck on SRAM_ECC_ERROR_FORCING_1BIT, the following API produces negative result and stuck into while(1) loop
boolean retVal;
SL_SelfTest_Result result;
retVal = SL_SelfTest_SRAM(SRAM_ECC_ERROR_FORCING_1BIT, TRUE, &result);
if(retVal == false){while(1);}Code

3. Flash ECC check enable is getting stuck on SRAM_ECC_ERROR_FORCING_1BIT, the following API produces negative result and stuck into while(1) loop
boolean retVal;
SL_SelfTest_Result result;

/* Flash test needs to be run from a RAM location. Copy flash test to RAM */
uint32 i;
uint32 size=(uint32)&ulHighHandlerSize;
for(i=0;i<size;i++)
{
((char *)&ulHighHandlerStartAddr)[i] =((char...Code

4. Peripheral ECC check enable is getting stuck on XXX_ECC_ERROR_FORCING_1BIT, the following API produces negative result and stuck into while(1) loop
if(SL_SelfTest_CAN(CAN_ECC_TEST_MODE_1BIT, SL_DCAN1) == false)
{
while(1);
}
if(SL_SelfTest_CAN(CAN_ECC_TEST_MODE_2BIT, SL_DCAN1) == false)
{
while(1);
}
if(SL_SelfTest_CAN(CAN_ECC_TEST_MODE_1BIT, SL_DCAN2) == false)
{
while(1); ...Code

5. CCMR5TEST ENABLE is getting stuck on CCMR5F_CPUCOMP_SELF_TEST, the following API produces negative result and stuck into while(1) loop,

boolean retVal;
SL_CCMR5F_FailInfo failInfo;

retVal = SL_SelfTest_CCMR5F(CCMR5F_CPUCOMP_SELF_TEST, TRUE, &failInfo);
if(retVal == false){while(1);}
if(failInfo.stResult != ST_PASS)
{
while(1);
}
Code

6. STC ENABLE is getting stuck on STC1_COMPARE_SELFCHECK, the following API produces negative result and stuck into while(1) loop,
SL_STC_Config stcSelfTestConfig;
boolean bResult;
stcSelfTestConfig.stcClockDiv = 2; /* STC Clock divider = 1 */
stcSelfTestConfig.intervalCount = 1; /* One interval only */
stcSelfTestConfig.restartInterval0 = TRUE; /* Start from interval 0...Code

Other API is getting pass like SL_SelfTest_PBIST for RAM, ROM, VIM,

Please suggest me the solution,

Thank you,

Vikas N.

RM57 has EPC module. The EPC captures the address of correctable error and puts the address into the Content-addressable memory (CAM). If the error address is already in the CAM, the error is discarded, and no error is generated to ESM.

Can you please use the example project included in SDL?

Hello Qj Wang,

Thanks for the details

I have tried the example you have suggested and the code is getting stuck in HL_sys_startup.c line number 460

My apologies I am not able to attached the code file mentioned above as image snapshot. But if you could open the code at your location, the line number is already mentioned above (Ln-460)

Please suggest solution.

Thank you

Vikas N.

Hi Vikas,

Will try.

Please use "drag and drop" to place a image file. The Insert->Image/video/files doesn't work at this moment.

Hi Vikas,

I will run the test to see if I can get the same issue.

Hello Qj Wang,

Thank you for compiling and running test from your side, Is there is any update on the same.

and from my side Instead of halcogen example I have imported the example code from \SafeTI Diagnostic Library\2.4.0\build\RM57L843_NoOS for Rm57l843 and test all the API "app_main_NoOS.c" and observed all APIs getting fail as the periodicSTFailCount = 44,

Please Suggest a solution.

Thank you

Hello QJ Wang,

The following changes we have done in safety lib as

    /* Check if there were ESM group3 errors during power-up.
     * These could occur during eFuse auto-load or during reads from flash OTP
     * during power-up. Device operation is not reliable and not recommended
     * in this case.
     * An ESM group3 error only drives the nERROR pin low. An external circuit
     * that monitors the nERROR pin must take the appropriate action to ensure that
     * the system is placed in a safe state, as determined by the application.
     */
    if ((esmREG->SR1[2]) != 0U)
    {
        //for(;;)
        //{
        //}/* Wait */
    }

    /* Initialize System - Clock, Flash settings with Efuse self check */
    systemInit();

This change is done because, esmREG->SR1[2] value is 8 and SL_ESM_nERROR_Active status is false which is chage to true in sl_esm.c file,

by making these changes, ALL APIs are working now except CPU check and flash ECC check,

Please suggest the solution and confirm the change is valid,

Thank you.
