External debugger NUCLEO-H743ZI2

The goal: Debug the NUCLEO-H743ZI2 with Tracealyzer.

To do it I have to connect the board with my computer via jlink. I found the tool STLinkReflash, that can emulates the jlink in the stlink. The problem I found is that it does not work for the stlink V3.

On the other hand, I have another nucleo board, NUCLEO-L746RG that has stlink V2-1, with which I got success emulating the Jlink and debugging with Tracealyzer.

I am trying to connect the STlink that is in the NUCLEO-L746RG with my development board NUCLEO-H743ZI2, but I do not get success.
I also tried to connect a comercial STlink V2 device with the NUCLEO-H743ZI2, just connecting the jumper JP1 and connecting the STlink to the CN5, but I get these errors: "Error: target voltage may be too low for reliable debugging" "Error: init mode failed (unable to connect to the target)".

Please, could you show me how do I have to do the connection to debug the nucleo H743ZI2 with an external tool?

Thanks in advance.

Hello @Manu Gr,

Supported ST-Link versions are detailed here: ST-LINK On-Board (segger.com)

I suggest checking connections to the Nucleo H743. Try connecting under reset also to CubeProgrammer using SWD.

Are you sure that tracealyzer cannot use ST-LINK? Their documentation suggests that they need ITM trace, and ST-LINK supports it. ST-LINKv3 should  yield good performance.

Thanks for your answer.

I found a tutorial where they debug the Nucleo-H743 with the STLink. They use tracealyzer as plugin of STM32Cube. The problem for me is that I don't use STM32Cube, I use VSCode with PlatformIO and then I have to configurate manually the following fields:

  • Target Speed: I guess the system clock. Is that right?
  • Prescaler: I don't know what to set.
  • TPIO/SWO Base: I don't know what to set.
  • ITM Channel: The one that I configure in trcStreamPortConfig. But I don't know if I have to configurate something else.

Programming and the basic debugger in platformIO work for me, so the connections are not the problem. But now I am interested in using some more powerful tools for debugging.

Additional information: I am not using HAL libraries, just CMSIS.
