How to view and retrieve the wakeup reason in S32K344?

I see all zeros in the watch registers. Has the system been reset after wakeup?

via Attach to Running Target

I use PTB0 UART RX as the wakeup source.

EVB: S32K3-T-BOX

RTD3.0.0

S32DS v3.5

Hi

Have you already refer to the S32K344_FlexCAN_Wkup_S32DS_3_4_RTD_LLD_2_0 example in S32K3 Low Power Management AN and demos?

What debugger are you using for Attach to Running Target? Have you tried reading the reset reason via Power_Ip_GetResetReason();?

Best Regards,
Robin

I have already seen the demo.

I use Mcu_ResetType Mcu_GetResetReason(void); to display the following reasons:

MCU_SW_DEST_RESET = McuConf_McuResetReasonConf_MCU_SW_DEST_RESET,                           /**< @brief HSE SNVS tamper detected. RGM_DES[F_DR17]. */

I am using PEmicro Debugger.

I have attached my project below. If possible, please help me check where the issue might be.

I enter standby mode through the standby command under FS26_handle.

Hello @iverson3ya,

I saw that you didn't call Icu functions to initial wakeup.

Please add some below code into your project and let me know your test result.

Icu_Init();

Icu_EnableWakeup();

Icu_EnableNotification();

Or:

Wkpu_Ip_Init();
Wkpu_Ip_EnableInterrupt();

Best regards,

Dan
