as @STTwo-32 already said, see this article:

https://community.st.com/t5/stm32-mcus/how-to-redirect-the-printf-function-to-a-uart-for-debug-messages/ta-p/49865

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

Tip:

Get the basic direct UART output working before adding the printf stuff.

That doesn't make sense!

As its name suggests, the stm32f429i-disc1 board contains an stm32f429i microcontroller - not an stm32f103cbt6.

But, anyhow, the method to get printf working is the same irrespective of what microcontroller you use.
