Internal RTC as wakeup source for S32k358 Non-AUTOSAR

[agouda]

Dear NXP team,

Using S32DS IDE  ( RTD 5.0 ) for Non-AUTOSAR configuration (not EB)

I am trying to configure wake up soures as below :

1 - PTD_27 ( external pin PTD_27 WKPU[51] , wakeup channel 55)

2- Internal RTC ( RTC-API RTC timeout).

by pressing on switch at PTD_0 : the controller goes to standby mode ( Power_Ip_SetMode(pointer to standby mode)).

wake up via external source  PTD_27 ( wakeup channel 55) is working fine, and the controller wakes up as expected.

wake up via RTC is not working for some reason. even I have configured ( WKPU , POWER, RTC, Clock [2 configurations] ).

I have attached my project for you to check it ( RTD 5.0 ). please let me know if you need more infomration.

I would appriate your support.

thanks in advance

Hi Robin,

thank you for the hint. 

I enabled SIRC in standby mode, and it's waking up now periodically as expected.

Hi

RTC can be the low-mode wakeup source when SIRC is configured to be enabled in standby mode.
