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?

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.

Hello,

I removed I2S stuf, but still not working. Also i get "Break at address "0x8003b30" with no debug information available, or outside of program code."

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.
