stm32f4系列调试usb_hs程序初始化不成功,使用stm32cubemx生成的程序

1169853821

使用stm32cubemx,参考网上教程生成usbhs的程序,初始化不成功会卡在usbd_conf.c的USBD_LL_Init(USBD_HandleTypeDef *pdev)的
  if (HAL_PCD_Init(&hpcd_USB_OTG_HS) != HAL_OK)
  {
    Error_Handler();
  }
会进入error_handler()就死循环了.使用过三块板子f407,f446和f429都不能成功运行.f407杜邦线连了个usb3300的板子.f446的板子自带usb3300,f429是正点的阿波罗开发板.
目的是调试f446的板子usbhs正常吗.

1.不清楚HAL_PCD_Init的作用.
2.使用usb 外带phy跑hs一定要正确连线吗,不然不能正常初始化?
3.如果不是连线板子问题,那会是我cubemx的配置有问题吗,但我参考网上的教程配的.

求大佬指点,如果有踩过同一个坑的,能告诉填坑方法,没有的能指点一下可能出现问题的地方.急!

继续debug发现卡在了
  if (USB_CoreInit(hpcd->Instance, hpcd->Init) != HAL_OK)
  {
    hpcd->State = HAL_PCD_STATE_ERROR;
    return HAL_ERROR;
  }
这个USB_CoreInit过不去.

用外置PHY必须线接好，不然初始化会卡死
