Using RTC with KDS, PE and MQX

My interest is merely in using the RTC as a Date/Time source and be able to read the current value when needed.. While setting this up, the PE insisted that I need an interrupt handler to keep MQX happy.

 

If I just put a RTC_DRV_GetDatetime() in the code and print the results, the time does not increment. Figuring that I might need to call RTC_DRV_init(), I put it in there and it appears that I end up in the DefaultISR infinite loop.

 

Note that the interrupt routine rtcTimer1_irqHandler() has a NULL body and that the interrupt for RTC_Seconds is disabled in PE.

 

How can I use the RTC as just that in an MQX environment?

 

Note that this is on a FRDM-K22F board.
