一、内核配置
device drivers --->
[*] usb support --->
usb gadget support --->
[*] debugging messages (development)
[*] verbose debugging messages (development)
[*] debugging information files (development)
[*] debugging information files in debugfs (development)
(2) maximum vbus power usage (2-500 ma)
(2) number of storage pipeline buffers
usb gadget drivers
ethernet gadget (with cdc ethernet support)
[*] rndis support
cdc composite device (ethernet and acm)
二、编译内核和驱动模块
1. 编译内核；编译驱动模块
2. 所需的驱动模块位置如下：
drivers/usb/gadget/function/u_ether.ko
drivers/usb/gadget/function/u_serial.ko
drivers/usb/gadget/function/usb_f_ecm.ko
drivers/usb/gadget/function/usb_f_rndis.ko
drivers/usb/gadget/legacy/g_ether.ko
drivers/usb/gadget/libcomposite.ko
3. 配置模块
更新内核，将驱动模块拷贝到板子上
4. 编写脚本
脚本内容如下
insmod /home/root/usb_to_net/u_serial.ko
insmod /home/root/usb_to_net/libcomposite.ko
insmod /home/root/usb_to_net/u_ether.ko
insmod /home/root/usb_to_net/usb_f_rndis.ko
insmod /home/root/usb_to_net/usb_f_ecm.ko
insmod /home/root/usb_to_net/g_ether.ko
ifconfig usb0 up
ifconfig usb0 192.168.0.136
注意：加载脚本的顺序不要出错了
5. 运行脚本
如果出现以下打印则表示加载驱动成功

7. pc设置enp0s26f7u5的ip
ifconfig enp0s26f7u5 192.168.0.135
注意：这里可能需要权限
8. 板子和pc机相互ping
pc机ping板子打印如下
[yw@192 kernel-source]$ ping 192.168.0.136
