Hello
I am using STM32RBT6 with my board and all is good except serial with 115200 baud rate, 57600 and lower is working correctly.
I just see weird characters when receiving data.
I can't get it work either with USART1 or USART2. I don't use any pull up resistor, just direct connection.
I tried 50mhz gpio and different gpio input type, but nothing helped. My board contain 8mhz external crystal, cpu is running 72mhz.
Even with my other board, LC Studio brand with same processor I getting same results, same with usb ttl converter and rs232.
I am using ST's std library V3.4.0 with interrupts for receiving.

Thanks
