Interrupt api is not called in case of SMR Verification is Periodic in S32K3

[HyunungPark1]

Hi.

Interrupt api is not called in case of SMR Verification is Periodic in S32K3.

Could you please let me know why Interrupt api is not called?

Hello @HyunungPark1,

Could you send me the code implemented in the CDD_InitFTDConfiguration() function and Fls configuration?

And what is the HSE Firmware you are using?

Best regards,

Dan

Hi.

Hello @HyunungPark1,

I saw that you have not called "Hse_Ip_Init(MU0_INSTANCE_U8, &HseIp_MuState);" in your code to init MU_0.

So, you need to call "Hse_Ip_GetHseStatus(MU0_INSTANCE_U8);" and "Hse_Ip_Init(MU0_INSTANCE_U8, &HseIp_MuState);" after "IntCtrl_Ip_EnableIrq(HSE_MU0_ORED_IRQn);"

Best regards,

Dan

Hi

my code call Hse_Ip_Init like below code

/* Install ORed GP interrupt for MU-0 */

  IntCtrl_Ip_InstallHandler(HSE_MU0_ORED_IRQn, &Mu_Ip_Mu0_OredGP_Isr, NULL_PTR);

  /* Enable ORed RX interrupt for MU-0 */

  IntCtrl_Ip_EnableIrq(HSE_MU0_ORED_IRQn);

/* Initialize Crypto driver */

Crypto_Init(NULL_PTR); ==> Hse_Ip_Init is called by this api

RetVal = Crypto_GetAttribute(HSE_SECURE_LIFECYCLE_ATTR_ID,sizeof(hseAttrSecureLifecycle_t) ,(void *)&gHseCurrentLC);

if(RetVal == E_OK && (gHseCurrentLC & HSE_LC_CUST_DEL == HSE_LC_CUST_DEL)){

RetVal = CDD_CheckKeyProvisioning();

if(RetVal == E_NOT_OK){

/* Format HSE key catalogs (RAM + NVM) */

RetVal = Crypto_Exts_FormatKeyCatalogs();

//CDDAssert((Std_ReturnType)E_OK == RetVal);

}else{

}

}else{

RetVal = E_OK;

}

Hse_Ip_RegisterGenericCallback(Crypto_aPartitionToMuMapping[0].u8MuInstance, u32NotifEventsMask, GenericPurposeCallback);

return RetVal;

BRs.

Hello @HyunungPark1,

I have a question: when you perform step 6 (Reset Device) then after that: Is your program run step 1 to 5 again?

Best regards,

Dan

[HyunungPark1]

Hello Dan

My program doesn't run step 1 to 5 again after step 6 (Reset Device) 

Best Regards.

Hello @HyunungPark1,

If your program doesn't run step 1 to 5 again after step 6 (Reset Device) then it mean the value of registers was reset and indicated that HSE_MU0_ORED interrupt was not enable when you perform test.

Best regards,

Dan

[HyunungPark1]

Hello Dan.

I think that HSE_MU0_ORED interrupt is enable because the below code is performed after device reset

/* Install ORed GP interrupt for MU-0 */
IntCtrl_Ip_InstallHandler(HSE_MU0_ORED_IRQn, &Mu_Ip_Mu0_OredGP_Isr, NULL_PTR);

/* Enable ORed RX interrupt for MU-0 */
IntCtrl_Ip_EnableIrq(HSE_MU0_ORED_IRQn);

Best Regards.

Hello @HyunungPark1,

Sorry for my late response.

Did you check the below bits in your program?

NVIC->ISER6 bit 4: Set if you enabled MU0 interrupt.

NVIC->IABR6 bit 4: Set if iMU0 interrupt occurred.

Best regards,

Dan
