S32K148 Can not wakeup to RUN mode from VLPS mode config in MCAL EB tresos and davinci software

ananan — Wed, 24 Nov 2021 03:45:16 GMT

At present, s32K148 enters VLPS mode from RUN mode, and the test circuit board current changes from 120mA to 9mA. It feels that the circuit board has entered VLPS mode, and the WFI command is executed. During the simulation, the following WFI command is not executed.

Then, I configured the Icu module and added the wake source and Sleep mode of Icu and EcuM in davinci Config software. The INTERRUPTION of THE Icu was working, but the Icu pin was triggered externally after Sleep, but the test current did not respond

The following figure shows the register values when entering VLPS

Now I don't know how to wake up MCU. I hope experienced experts can help me!

Hello @ananan ,

Could you please check if Icu pin was triggered externally after Sleep, then is the ICU interrupt handler called.

Best regards,

Hung

In VLPS mode, THE Icu interrupt cannot be triggered because I called serial port print in the Icu callback function, but in RUN mode, the Icu interrupt is working and when the Icu interrupt is triggered, the callback function can be called

Hello @ananan ,

As I understand, the Icu interrupt handler cannot be called if your application is in VLPS mode. Could you please confirm. Could you please also share if you are using OS in your application. If yes, could you please share the Priority of the Icu interrupt handler and also share the value of BASEPRI in in VLPS mode

Best regards,

Hung

I used freertos system, icu priority is 2, freertos boundary function priority is 7, as shown in the picture below, is you said "the value of BASEPRI in VLPS mode" is the freertos boundary function priority?

Hello @ananan ,

Could you please run to the WFI then check the basepri(above picture) value

Best regards,

Hung

the basepri value is above picture.

I tested the current of MCU is 8.3mA, and the supply voltage of MCU is 3.3V. I felt that MCU did not enter VLPS mode, but the MCU entered sleep mode according to the value of the register. How to explain this phenomenon?

all the pins are configed to the input mode.

Hello @ananan ,

Does you mean that the current is so high. If yes, we can reduce the current by disable all unused peripherals.

But the problem of wakeup is still unresolved

Hello @ananan ,

We can have a call to check it together. Could you please share your email and also suggest the time.

Best regards,

The program cannot enter Icu_Ipw_SetSleepMode, which means Icu cannot enter sleep mode. What is the cause of this

Hello @ananan ,

The Icu_SetMode just set all channel which does not use for wakeup to sleep mode. So with the channel which use for wakeup, the Icu_SetMode will not set it, this is normal behavior.

Could you please check if:

- When the MCU is in run mode, can your application can run to the ICU interrupt handler.

- When the MCU is in VLPS, can your application can run to the ICU interrupt handler.

Best regards,

Hung.

OK,I get it, thank you very much!

I followed the code you showed me yesterday, but after sleep, the code that triggered the external pin, the ICU interrupt callback function was not executed

When the MCU is in run mode, can your application can run to the ICU interrupt handler.

yes, mcu can run to the ICU interrupt handler.

- When the MCU is in VLPS, can your application can run to the ICU interrupt handler.

No. mcu can not run to the ICU interrupt handler.

Hello @ananan ,

Thank you for your information. Could you please share these below information(when the MCU is in VLPS mode):

- The pin which you are using for wake up.

- Value of PORT_PCR(of the wakeup pin) register.

- Value of NVICISER0, NVICISER1, NVICISER2, NVICISER3

- Push the wakeup pin in the VLPS mode and check the value of NVICISPR0, NVICISPR1, NVICISPR2, NVICISPR3

Best regards,

Hung
