running a Linux system on the Development Board, you can use the cross-compilation debugging environment to connect the development report to a PC. In this way, the debugging information can be printed on the terminal of the host through the serial port. Otg_ip can connect to the PHY chip through the ULPI interface and connect to the USB device. After the device controller

The Linux USB Gadget device driver can be used to implement some interesting functions. For example, 1.
