UART baudrate configuration CubeMx

Hello,

I use the Nucleo-L476RG to send and read data by the UART, so for that I used STM32CubeMx,

the goal is to send data in a Maximum of baudrate which is 10Mb/s as shown on the picture below, but the code is excuted only if the baudrate is less than 1Mb/s, otherwise I don't recieve any information in RX,

for information, I test sending information by a led, if it flashes, it means that it's OK otherwise, it is NOK,

I don't understand what's kind of problem is about!

Thanks

Hello,

how do you handle UART RX reception?

Hi, yes I tried many programs for RX(putty, ...) and I can show the message only if UART baudrate is less than 1Mb/s, 

I think taht the problem is about TX and not RX,

Hello

‌,

my question is how to you handle receive on STM32 side? Do you use interrupts, polling, DMA?
