Hi team,
I am using STM32G0B1 for my project development were I use PA4 as a ADC_IN in analog mode and using RTC for date and time setting, though I am not using(/set) RTC_OUT but 1 Hz RTC calibration output getting activated at power on or at rebbot.
To fix this issue I explicitly calling the “HAL_RTCEx_DeactivateCalibrationOutPut(&hrtc)” in main.c this fix the issue.
What is the expected fix of this issue? why its occuring ? does the place/time of calling that API matters?
