STM32F401CC Clock configuration

We are developping an application on STM32F401CC mcu and we are not sure that our clock configuration is correct because, when we are setting baud rate of USART1 or USART2 greater than 115200 bps, data exchange on USARTs doesn't work as expected.

We are using HSI clock at 16 MHz and we are setting the SYSCLK value at 84 MHz. PLL (HSI) is used as system clock source.

Could you please tell us if you see something wrong in our system_stm32f4xx.c ?

Thank you for your support,

Best regards,
