ChibiOS Free Embedded RTOS

with chibios on F4 device,

can one set say UART2 at 1200 baud and also have UART3 running at 115200 baud ?

Reason i ask is to get to 1200 baud i had to change the STM32_PPRE1 to achieve this, but is this now too slow for the other UART on the same APB bus that i need 115200 baud ?

I don't know if it is too slow, you should make calculations and verify you are within 2% or so.

Anyway, USART1 and USART2 run from PPRE2, you may use those.
