How to use printf in stm32f429i-disc2

Hello,

How to use printf in stm32f429i-disc2 board and my MCU is stm32f103cbt6

Before getting into printf, do you have the basic HAL UART (or bare-metal) comms working?

printf relies upon that, so you need to have that working first:

Then read this Knowledge base article:

And here's a 3rd-party article on the same:

You can refer to the web for that. 
I hope it will be helpful.

Cheers :)
