RTC Problem

I use the NUCLEOH563-ZI board and I want to use RTC. I configured the RTC with the LSI clock. I loaded a default date/time. On the other hand, my time does not change...

My Init code :

My source code to retrieve the time

Thank you for your help !

Hello @Ghislain_Clement, 

Please check if the RTC_TR and RTC_DR registers get updated

THANKS ! I found the solution. I initialized the time before the date and it works.
