F407G-DISC1 RTC not working

Question

I use F407G-DISC1 and RTC values dont change i have. In project i have I2S sound filtering and button that displays number on LEDs in binary, when button is pressed. But nothing happening on button press. Did i missed something? /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * *

Hello,"still not working" does not bring much information as we don't have your environment. Tell what you tried to do to debug."Break at address "0x8003b30" -> now forget about RTC and check your chip. Create a very simple project for example toggling a GPIO and find if you have the same issue.

Hello,To find issues for a specific peripheral, try to simplify your code to focus on that issue. So remove all the code not related to the RTC and confirm if you have the same behavior.
