2024/9/19 19:59
2. 上位机配置
2.1 添加 rndis 和 gserial 主机驱动
进入 kernel 目录 make menuconfig，1．添加配置 CONFIG_USB_NET_RNDIS_HOST=m：
2．添加配置 CONFIG_USB_SERIAL=m：
2．添加配置 CONFIG_USB_SERIAL_GENERIC=y：
编译模块：make modules && make modules_install
2.2 加载驱动
1． 加载 rndis 主机驱动：modprobe rndis_host
2． 连接下位机，确认 rndis 驱动绑定 rndis 接口
3． 查看下位机的 usb 设备 ID：
# lsusb
Bus 001 Device 006: ID 18d1:181f Google Inc.
4． # lsusb -t
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/6p, 480M
|__ Port 1: Dev 15, If 0, Class=Wireless, Driver=rndis_host, 480M
|__ Port 1: Dev 15, If 1, Class=CDC Data, Driver=rndis_host, 480M
|__ Port 1: Dev 15, If 2, Class=Vendor Specific Class, Driver=, 480M
|__ Port 1: Dev 15, If 3, Class=Vendor Specific Class, Driver=, 480M
|__ Port 1: Dev 15, If 4, Class=Vendor Specific Class, Driver=, 480M
|__ Port 1: Dev 15, If 5, Class=Vendor Specific Class, Driver=, 480M
5． 加载 gserial 主机驱动：modprobe usbserial vendor=0x18d1 product=0x181f
其中，0x18d1 是从机的 VID，0x181f 是从机的 PID
6． 确认 gserial 驱动绑定 gserial 接口：
# lsusb -t
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/6p, 480M
|__ Port 1: Dev 15, If 0, Class=Wireless, Driver=rndis_host, 480M
|__ Port 1: Dev 15, If 1, Class=CDC Data, Driver=rndis_host, 480M
|__ Port 1: Dev 15, If 2, Class=Vendor Specific Class,
Driver=usbserial_generic, 480M
|__ Port 1: Dev 15, If 3, Class=Vendor Specific Class,
Driver=usbserial_generic, 480M
|__ Port 1: Dev 15, If 4, Class=Vendor Specific Class,
Driver=usbserial_generic, 480M
|__ Port 1: Dev 15, If 5, Class=Vendor Specific Class,
Driver=usbserial_generic, 480M
3. 设备调试
3.1 端口识别
查看串口设备：
# ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3
查看网卡设备：
ls /sys/class/net/ -l
total 0

lrwxrwxrwx 1 root root 0 Oct 23 07:33 lo -> ../../devices/virtual/net/lo
# ifconfig usb0 192.168.1.15

RX bytes:384 (384.0 B) TX bytes:51178 (51.1 KB)
3.2 AT 及灌包测试
1．通过 USB 连接上位机后，使用 minicom 工具发送 AT 命令：
minicom -D /dev/ttyUSB0
2．利用 iperf 测试网络性能：
上位机配置 ipv4 地址：
ifconfig usb0 192.168.42.130
上位机作为 udp 服务端接收数据：
iperf -u -s -i 1
下位机作为 udp 客户端发送数据：
iperf -u -c 192.168.42.130 -i 1 -p 5001 -t 30 -b 200m
上位机作为 udp 服务端接收数据：
