Hello Folks,
I am facing the issue regarding the RTC in stm32H7S78-dk evaluation board. So, the issue is if I configure the internal RTC in my IOC file all the other the process stops on my board which is working already like TouchGFX, Ethernet my LCD screen all the the operations stopes. So, what is the actual issue with RTC. Your inputs will be appreciated. Thank you!

Hello,
Could you please provide more details about the steps you're taking when this issue occurs? In my experience with the STM32L4, a similar problem arose when performing a reboot from the bootloader after a firmware update. In that case, the bootloader cleared the enable flag, preventing the RTC from being properly initialized. This led to the application failing to start correctly after the bootloader had run.

Understanding your specific sequence of operations and how you're configuring the RTC would help in diagnosing the issue more accurately.

So what debugging have you done to find what's happening? What's blocking these processes?

This are the two simple steps which I am doing to enable RTC.
- First, I am setting the RCC HSE and LSE to Crystal/Ceramic Resonator.
- Second, I am enabling the RTC and setting the basic config steps.
By just enabling this my other process stops working.

Again, what does that mean?
Use the debugger to see what's actually happening ...

it means my actual application of TouchGFX, WiFi/BLE and Ethernet is not working.

But what, exactly, does "not working" mean?

Okay
