Currently i am working with nucleo-h743zi2 board. I set the Baud rate in CubeMx to 115200. In the Hercules program, when I set the baud rate to 115200, the data does not flow correctly, but when I set the baud rate to 38400, it flows correctly. Why m...

Before the problem is solved, i chose the HSE from the clock configuration in CubeMX. After i read the documentation, i chose the HSI clock and my problem is solved. Uart receiver and transmitter is working fine now. I dont change anything except thi...

You can find it in the document in ST website which name is "STM32H7-Peripheral-USART interface (USART)". Write it google you will find this document. I attached the photo of the part where I solved my own problem.

I solved the problem. I was using HSE as clock. When I looked at the UART documentation for this card, I saw that clocks such as HSI, LSE should be used instead of HSE. Indeed, when I changed the HSE, the problem disappeared and communication took pl...
