Can't break at Cortex®-M4 address on STM32H7 dual core.

[Paco]

Hi All,

I am using STM32H747IDISCO kit.

I load example project HSEM_COreSync into STM32CubeIDE(version 1.18.1) , and set a breakpoint at

"BSP_LED_On(LED3);" line in main function on Cortex®-M4 side. And I start debug, but break doesn't occur.

I recognize LED3 is turned ON after LED1 turned OFF. So "BSP_LED_On(LED3);" line should be proccessed, but break doesn't occur.

I program the board following the guide.

Could you tell me how to break at  Cortex®-M4 address on STM32H7 dual core.

Thanks in advance.
