Hi All,
I'm starting a developpement on STM32F4Discovery.I want to use the two USB controler (HS and FS) in CDC Host and device to implement a serial to USB bridge.OTG FS peripheral on device side to connect to PCOTG HS peripheral on Host side to receive CDC USB dongles.I have implement the OTG FS peripheral and it work fines with a PC on Windows XP.I'have used the usbd_cdc_core.c and define USE_USB_OTG_FS.Now I need to implement the host side. I have put a look at the DualCore code before.Then I declared the USE_USB_OTG_HS and called the USBH_Init to initialize the Host side with USB_OTG_HS_CORE_ID.Since I have been set the USE_USB_OTG_HS, the CDC on the device side won't receive any serial data on the usbd_cdc_DataOut.The usbd_cdc_DataIn works fine.I have seen in the usbd_cdc_core.c that it use the USE_USB_OTG_HS.Does I make any change on this file?Does anyone have made any implementation like this ?Best regards,Pascal
