Hi Everyone,
We have managed to increase the clock speed for STM32F722 using PLL. Now we are wondering how we can keep the baud rate of USART6 to 115200 bit/s (is there any function/capability in STM32F722 that automatically adjusts the USART clock divider and set the baud rate after changing the Micro's clock speed or no?)
Your quick response is highly appreciated.
Thanks,
Dan

Thanks Clive for your answer.
No, the USART isn't in transaction when we change the baud rate.... we don't know exactly what the source of this problem is. It happens when we set the PLL to generate higher frequencies than 12 MHz.
