Hardfault interrupt while accessing any RTC register of MK22FX512AVLQ12

Hi,

I am using MK22FX512AVLQ12 microcontroller. While initializing RTC using RTC_Init(RTC_Type *base, const rtc_config_t *config) function from "fsl_rtc.h" file, my code goes to hardfault interrupt.

On further debugging i found that the code goes to hardfault interrupt when i try to read/write any RTC register.

I have attached my code for reference, please help in resolving this query.

Thanks & best regards,

Prasanna

Is your RTC powered by the external Bat/RTC pin? Otherwise it will hardfault.

I hope this helps,
