This is to use a printf over the serial wire viewer

You can refer to this article: Using the ITM console for printf redirects and LWIP debug messages

Hello @JhonVijay and welcome the the ST community,

Not sure I understood the question. The on board STLINK-V3 is intended to connect to the on-board MCU in your case: STM32H753 MCU.

You can use it with STM32CubeIDE for debug, you can use it with STM32CubeProgrammer to upload, read to/from the internal or (if available) an external flash.

You can also refer to the board's user manual UM2407 / section 7.3 Embedded STLINK-V3E

You can connect a J-LINK on CN5 connector on NUCLEO H753ZI:

Please refer to the user manual of the board UM2407 / section 7.3.3 Using an external debug tool to program and debug the on-board STM32H7

For STLINK you can use the external version STLINK-V3 (I don't know what the reason to use an external version while there is one on board)

Hope that does answer your question
