Hello everyone, I want to set communication between outer world(USB) and inner world(STM32F407) in high speed. I used STM32F407VE as MCU and USB3320c-EZK as USB_PHY. And STM32CubeIde is used to generate code and proggraming ST.

I have some problems about programming USB CDC. The program goes into ERROR_HANDLER in   MX_USB_DEVICE_Init();. I think I made a mistake during set the configuration for running USB_OTG_HS and USB_DEVICE in ioc. (gui of STM32CubeIde).

In " STM32F4xx_hal_pcd.c " file, USB_CoreInit(hpcd -> 0 Instance, hpcd ->Init ) != HAL_OK )

{hpcd -> State = HAL_PCD_STATE_ERROR;

return HAL_ERROR;

}

hpcd is returned as HAL_ERROR and then, go into while loop of ERROR_HANDLER ?

What could be possible reason for this problem?

Thanks for attention.
