Zero通过otg与PC共享网络

修改内核

在内核选项中勾选上Ethernet Gadget, 就可以让Zero与PC通过usb共享网络。

Location:
-> Device Drivers
    -> USB support (USB_SUPPORT [=y])
        -> USB Gadget Support (USB_GADGET [=y])
            <*>   USB Gadget precomposed configurations (Ethernet Gadget (with CDC Ethernet support))

配置zero网卡

on zero

打开usb0网卡

ifconfig usb0 up

设置usb0 ip

usb0 192.168.2.100 netmask 255.255.255.0

由于usb网卡默认关闭,所以建议将该文件写入开机脚本,上电即可使用ssh连接。

修改/etc/init.d/S40network

  start)
        printf "Starting network: "
        /sbin/ifup -a
        /sbin/ifconfig usb0 up
        /sbin/ifconfig usb0 192.168.2.100 netmask 255.255.255.0
        [ $? = 0 ] && echo "OK" || echo "FAIL"
        ;;
  stop)
        printf "Stopping network: "
        /sbin/ifdown -a
        /sbin/ifconfig usb0 down              
        [ $? = 0 ] && echo "OK" || echo "FAIL"
        ;;

on pc(linux)

ifconfig -a

usb0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

如果出现:

enx1288194be3c3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

可以尝试重启ubuntu,然后就可以正确识别。如果还不行,也可以以enx1288194be3c3代替usb0继续执行后面操作。

为usb网卡分配ip

ifconfig usb0 192.168.2.1 netmask 255.255.255.0

然后就可以ping通了

需要注意的是,此时Licheepi Zero只能访问主机ip地址,所以是无法正常上网的。

on pc (Windows)

Windows不能很好的识别Licheepi Zero的usb网络,需要手动安装驱动,详情参考测试测试 g_serial / g_ether USB Gadget (RNDIS) / 全志 V3S/F1C100s/X3/D1/R329/AIC800 / WhyCan Forum(哇酷开发者社区)

SSH连接

在linux中,可以直接在终端中ssh连接

 lithromantic@ubuntu: ~
 $ ssh root@192.168.2.100        [20:41:18]
 root@192.168.2.100's password: 
 # ls
 badapple.mp4  demo

如果需要移动文件等操作,可以使用scp,或者在文件管理器中添加sftp://192.168.2.100 以文件夹形式打开Licheepi Zero的磁盘。

对于windows,如果驱动安装失败,可以通过ssh桥接的方式连接LicheepiZero(需要linux虚拟机)。

操作如下
