Debug STM32H747 dual core application with Keil uVision

[CRoes.4]

I am trying to debug a dual core processor (STM32H747) with Keil uVision and ST-LInk V3. The application is running successfully on both cores but when i try to debug the CM4 core while the CM7 core is already running in another debug session, the CM4 core stops when i start the debug session. I am able to start the CM4 within the debug session.

I wonder why this is not working because if i use an old ULINK2 debugger i am able to connect to the CM4 core without stopping (Debug setting: Connect without Stop used).

For the ST-LINK the following debug options are still disabled at the Keil uVision.

• Load Application at Startup
• Connect Normal
• Update Target before Debugging

Best regards
