NUCLEO-H755ZIQ ST-LINK error: (4) No device found on target when debugging CM7 core

[Akhila_17]

Hello,

I am working with the NUCLEO-H755ZIQ board (STM32H755ZIT6) and trying to debug my CM7 core project in STM32CubeIDE. Below i have attached the screenshots that i am getting with STM32CubeIDE and Cube programmer. Can anyone help me resolve this issue as early as possible.

 

Looking for solution.

Best regards.
