内核配置

驱动加载

  1. 此项功能依赖于 u_ether.ko usb_f_rndis.ko usb_f_fs.ko g_ether.ko，直接使用modprobe g_ether.ko即可
  2. 查看板子输出,会多出一个叫usb0的网卡

脚本加载驱动

  1. 除了上边加载驱动外，还可以通过脚本来开机加载

    start() {
        printf "Starting RNDIS: \n"
    	mount none /sys/kernel/config -t configfs
        modprobe libcomposite.ko
    	modprobe u_ether.ko
    	modprobe usb_f_rndis.ko
    	sleep 1
    	cd /sys/kernel/config/usb_gadget/
    	mkdir g1
    	cd g1
    	echo "0x0502" > idVendor 
    	echo "0x3235" > idProduct  
    	mkdir functions/rndis.rn0
    	mkdir configs/c1.1
    	ln -s functions/rndis.rn0/ configs/c1.1/
        sleep 1
        ls /sys/class/udc/ > /sys/kernel/config/usb_gadget/g1/UDC
        [ $? = 0 ] && echo "OK" || echo "FAIL"
    }

    stop() {
        printf "Stopping RNDIS: \n"
        echo > /sys/kernel/config/usb_gadget/g1/UDC
        [ $? = 0 ] && echo "OK" || echo "FAIL"
    }

    case "$1" in
        start)
        start
        ;;
        stop)
        stop
        ;;
        restart|reload)
        stop
        sleep 1
        start
        ;;
      *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
    esac

    exit $?

  2. 将文件保存到/etc/init.d/S97rndis这里即可开机加载驱动，效果是一样的

配置网卡

  1. 板子上执行

#ifconfig usb0 192.168.8.190 netmask 255.255.255.0
2. Linux电脑此时也会多出一个类似这个名称enp0s20f0u4的网卡

1
sudo ifconfig enp0s20f0u4 192.168.8.195 netmask 255.255.255.0
  1. 板子上ping一下是否畅通，这里的ip可以随便配置，我只是为了挂载NFS目录
  2. mount -t nfs -o nolock 192.168.8.195:/home/xfdr/nfs /mnt
  3. 这样就实现了通过USB来挂载NFS文件夹了，这样做比WIFI速度快不少，使用非常方便

注意：在win10上（build 1909）会被识别为串口，需要使用另外的驱动才能成功识别
