Have you enabled rtc on chip yet?
Difficult to understand why problems can sometimes happen in RT-THREAD
In my compilation on any version of the O.S. using STM32F417 all went fine.
define BSP_USING_ONCHIP_RTC
define RT_USING_RTC
deleted the WEAK in source file and changed to __weak
No alarm set
At leats I have no such problem, but have others.
Any time I power the board which has a tiny onboard battery all is fine. Time is not lost but only after weeks of power down of course.
