I try to run the RTC on an STM32WB55 nucleo board but i just reach to get 00:00:01.
Is there a command i don´t find in the examples to run the RTC.
I try to run with HSE/32 LSI1/LSI2 and LSE.
When I set the RTC witch HAL_RTC_SetTime() I can set the clock but the time is still standing on the setted clock value.
Is there a Solderbridge i had to remove or to Set on the nucleo?
Whene I read the manuale I belive that in the standard setting of jumper and solderbridge the RTC runs with the current of the ST-Link USB.
