NUCLEO H753Z: ST Link V3

[JhonVijay]

Hello everyone,

I am using the NUCLEO H753ZI microcontroller it has ST Link V3 can i debug this board with the ST Link can you tell me what version of ST do i need to get to debug my board and also can you provied me the document for debugging with ST link.
                           Thank you

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

I had debugged my Nucleo board with the J Link with the segger RTT. Now i like to change to STLINK So l would like to know what version of ST external debuger support my board which can be used for debuging my device

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

Note that RTT is proprietary to Segger - it is not supported on ST-Link.

Why external? Your board already has the ST-Link built in!

As for ST software, that's STM32CubeIDE.

You can also use STM32CubeProgrammer for programming.

All of this is linked from your Board's Product Page:

@Andrew Neil  .. If you remember our discussion ;)

Thank you @mƎALLEm  The thing is i had tryied to debug using the internal debugger to print the debugging messages by refering this vedio but i couldn't see the any debug messages so i wanted to try the external STLINK.Can you please proveide any documentation on debuging with the internal STLINK 

[mƎALLEm · Accepted solution]

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

But you could load your code OK, and use other debugger features like stepping, breakpoints, examining variables, etc?

As @mƎALLEm said, that video is about using SWV.

You can also get debug messages from a UART via the ST-Link's VCP (Virtual COM Port) ...

Thank you @mƎALLEm  I can able to debug using the onboard debugger
