In our design, we need to use UART0 & UART2 works at about 8Mbps, I found in the hardware design guide, the uart support up to 12Mbps, It seems the driver does not support buad-rate > 921600, How to make UART0 & UART2 works at higher buad rate?
please refer to Technical Reference Manual, you’ll need to configure device clock sources to have higher baud-rate. you should also selecting proper divisor values for the MSB and LSB bits of the baud rate generator.
you might refer to below for default clock sources, and also adjust baud-rate settings.
thanks
