S32K344 MCU Standby Mode Configuration

YashB — Fri, 28 Apr 2023 10:38:09 GMT

Can Anyone share a EB tresos Configurations for S32K344 with Standby Mode Configurations. I am a bit confused at my end. Do i need to configure two modes - RUN and STANDBY ? If possible please share a tresos configuration for the same

@danielmartynek Can you please help on this?

Hi @YashB,

Here are some example:

Have you seen them already?

Hello @danielmartynek , I do not have the RTD v2.0.0 required to view this. Can you send me the link for the same. I am unable to open the links to the S32K344 RTD software , it redirects me to the login page.

Hello @danielmartynek

I did some configuration changes in my existing project.

A short overview of my project- "We are trying to get the NFC 3321 to work with MCU Standby Mode"

So far the NFC chip is working perfectly fine in the RUN mode. I am attaching the project so you can see that we have configured Standby in MCU Mode Configuration in EBTresos.

Ideally we have NFC_IRQ that should wake up the system but since NFC chip is powered by GPIO. Is it possible that pin is getting disabled after we run the Standby command in our code?

P.S. Also I was unable to create a support ticket. Is there something wrong on the server side

Hi @danielmartynek,

I tried running the GPIO Wkpu example "S32K344_GPIO_Wkup_S32DS_3_4_RTD_MCAL_2_0" . Since i didn't have the 172 pin EVB, I tried to run it with the S32K3X4EVB-Q257 SCH-47827 REV-A . When I flashed the .elf file onto the HW using Lauterbach in PowerDownRecoverMode , it shows "running(power down)" without even pressing the button to initiate the Standby mode. Also the HW has a min consumption of around 68-70mA, which is not correct.

Hi @Danielmartynek, I tried the above projects onto the S32K344 SCH-47827 REV A EVB. I could not get them to run. The GPIO example shows "running (Power Down)" but it doesn't switches to the standby state or the wakeup state using the Push Buttons.

Did you get a chance to review this?

Hi YashB, If you call Mcu_SetMode(McuModeSettingConf_Standby), MCU will enter standby mode. I think we can call Mcu_SetMode(McuModeSettingConf_Standby) after generating a event and it is not directedly call Mcu_SetMode(McuModeSettingConf_Standby) after initializing MCU clock. You do not configurate IcuWkpu, so MCU will not wakeup by any event. Thanks! BR, Shunag

Hi YashB,

You can check VDD_HV_A current after showing "running (Power Down)" . VDD_HV_A current should be about 60uA after showing "running (Power Down)". If you enable Low-power debug in Trace32, Trace32 debugger will not be automatically disconnect after entering standby mode and will show "running (Power Down)".

Thanks!

BR,
