Hi,


In CubeIDE, new project, choosing STM32H755ZIT6 (the NUCLEO-H755ZI-Q), the board stops responding when turning off and on the power to the board. I have made a simple LED example with everything set to default with the addition of two user LEDs blinking - one controlled by M7 and one by M4 core. It works fine until you remove the USB and put it back in. Then ST-link cannot connect.

 

I have used the debug configuration from the application note:

Getting started with projects based on dual-core STM32H7 microcontrollers in STM32CubeIDE - Application note

 

STM32Cube Version: 1.17.0

CubeMX version: 6.13

Firmware package: H7 V1.12.1

 

Best regards Nikolaj

Additional info: Everything works when using older software releases - I can power cycle the board as much as I like and the program runs every time with the LEDs blinking.

With these software releases, everything works:

STM32Cube Version: 1.16.1

CubeMX version: 6.12.1

Firmware package: H7 V1.11.2
