Debug problems with STM32CubeIDE with Nucleo-H745ZI-Q

[NGuig.1]

Hello,

I have configuration problem of the STM32CubeIDE debugger with my STM32H7ZI-Q. When I launch the debug it crashes at the adress "0xa05f0000" with SIGTRAP and no more message, I try many things to debug it.

• First, I try this process : https://www.st.com/content/ccc/resource/technical/document/application_note/group1/18/43/cc/00/81/b6/4d/5c/DM00629855/files/DM00629855.pdf/jcr:content/translations/en.DM00629855.pdf

Unfortunately, it shows no results.

• Then, I go through this solution : https://community.st.com/s/question/0D73W000000PEtU/unable-to-debug-in-stop-mode-break-at-address-0xa05f0000-with-no-debug-information-available

No more results ...

• At least I try the solution on the first answer of the last question of : https://community.st.com/s/global-search/stm32h745zi-q?t=1587136301481

I reinstall, the V36 ST-LINK Firmware on :

https://www.st.com/en/development-tools/stsw-link007.html

But this solution doesn't work either and I made a step back now I cannot connect the board as a target. I have this error message "Error in initializing ST-LINK device.

Reason: (4) No device found on target."

So I have two main questions :

• First how I can fix the damage caused by the last solution ? ( I try to reinstall all the driver but the problems it still here)

• Then, How can I go through the debug of the IDE for flash and run the program on the board ? What is the setting that I don't see?

Thanks a lot for reading my questions and I hope you could answer they !

Hi I had ta similar problem with the Nucleo 755 on the M4 core. If I step through the code just behind the semaphore check, then I can press the play button without crashing the debug session.
