PWR_CSR2_USB33RDY flag is not set in Nucleo-H7S3L8

I was able to get CDC_Standalone in STM32CubeH7RS running on Nucleo-H7S3L8.

Next, I am trying to get USB FS CDC running based on the Templates_board project.

First, I need to modify the .ioc file to display the COM port in the Windows Device Manager. However, the USB regulator ready flag (PWR_CSR2_USB33RDY) is not set within HAL_PWREx_EnableUSBVoltageDetector(), causing a timeout.

I have attached the current .ioc file.

Any advice would be greatly appreciated.

I found the solution by myself.

As shown in the image, when “USBD_SELF_POWERED” is enabled, the USB regulator ready flag is now set.
