I have an application with the wakeup interrupt firing every x seconds. If the reset source is a power on reset, everything works as expected. However, when I upload a new code into the chip (so the MCU is reset by the ST-Link), the wakeup interrupt does not fire anymore, until I turn ON and OFF the power again.
Does anybody know why this is happening ? Is there a special handling that needs to be taken care of regarding the RTC ?
