I don’t know what the problem is with the nucleo but I tried two of them with the same result. But using the same processor STM32H745ZI in my board worked fine.

I suspect it might be related the power source of the processor Nucleo STM32H745 are configured for PWR_DIRECT_SMPS_SUPPLY

But I do not need any more help at the moment I am up and building on my board and that is all that matters but wanted to let you know if you run into again.

Thanks for your help on this. I am now certain this problem is related to the Nucleo-STM32H745. I tested it today on my custom boards using that has a STM32H745ZI with a segger J-link and works just as your tutorial says. So I think all is good with the software but might be a problem with the Dual Core Nucleo board.

Would it be possible for you to post the projects files from the tutorial at? https://visualgdb.com/tutorials/arm/stm32/multicore/

With these I could test it and see if I can find the problem.

Maybe your projects that worked for you will work for me. Otherwise I have tried everything I can think of to bring up the second core.

Thanks,

The second core never starts with or without debugger.

As mentioned I imported example that works in keil, After setting up the projects the M7 core will start but the M4 core will never start in visualGDB.

Note when importing the project and selecting the MCU there is no separate option for STM32H745zi_M4 like there is when you start a new project but I was able to hand configure the parameters for the core but something is still wrong.

Lastly I went a did a very simple example for core and could make it work in other products but could not make it work with visual GDB.

I also tried importing the keil project included in the Cube H7 package.

While it works in keil. After importing I can start M7 core but M4 core never leaves reset while debugging with VisualGDB.

Thanks,

I installed version 5.5 preview 7 and now debugging starts as you would expect but still the M4 core will not start.

Following the steps in your tutorial The M7 core starts fine but M4 does not start and stays huge in the reset handler.

I suspect I am missing some essential code needed to start the M4 code.

Thanks,
