Hello everyone, I got a new STM32F429 DISCO kit, i am working on it with Keil MDK-arm, but debug printf not working, Could anyone please help me to solve this?

Via a USART or SWV connection?

For SWV make sure the SWO solder bridges are made, the trace frequency matches the core settings​, and that you have retargeted output using ITM_SendChar.

Posted working examples in past and Keil has app notes on this topic.​

Hello Clive,

Thank You for your advise, it worked !!

The issue was SWO solder bridges were not made(SB9).
