Hi,

I try to push the UART of my STR710 to 460800baud. The problem is that I get only corrupted data. I think this has to do with the used external oscillator of 4MHz. Is there a possible PLL and divider configuration to run this speed with that frequency?

greets starkeeper

Hi starkeeper,

Try to increase the APB1 clock using PLL and configure the UART_BaudRate register with an adequate prescaler value.
