Starting USB device in STM32H753I Eval 2 development board

[bsn_14]

Hi 

We are trying to test USB Device - CDC standalone example with STM32H753i eval2 board. Our main.c code is enclosed herewith, 

Issue: if we call USBD_START() function in the main the LED Toggling code which is written below is not executing.

In Debug mode the system hangs at HAL_GPIO_WritePin.

If USBD_Start call is Commented, then Toggling of LED Observed in both run and debug modes.

Clock Configuration can be verified with the code.

Kindly share your suggestions.

Hi @bsn_14 

Could you please help us by reformulating the code to provide a minimal example that isolates the issue? We would like to see the essential parts of the code that are necessary.
