Tool/software:

Hi TI,

we want use RTC as a clock time for out system, we set "low Power Policy" standby0 , the clock works well on running status

But we call __WFI() and wake up it , the clock will go to default value, we check the time using API: DL_RTC_getCalendarTime

My question is: Does RTC calendar works on lower power mode? if yes , need any special configuration?

Hi,

The RTC calendar should work under low power mode. Have you tried the demo code in SDK? C:\ti\mspm0_sdk_2_04_00_06\examples\nortos\LP_MSPM0G3507\driverlib\rtc_calendar_alarm_standby

Best regards,

Hi,

I can build the project without errors. And I also debug the project and do not encounter your issue. The clock keeps going without reset.

Best regards,
