关于ethernet的调试验证总结

需要rndis修改的部分的串口配置
# audio accessory configuration

on property:sys.usb.config=audio_source

write /sys/class/android_usb/android0/enable 0

write /sys/class/android_usb/android0/idVendor 18d1

write /sys/class/android_usb/android0/idProduct 2d02

write /sys/class/android_usb/android0/functions${sys.usb.config}

write /sys/class/android_usb/android0/enable 1

setprop sys.usb.state ${sys.usb.config}

修改之后的串口命令：
在串口下操作一下命令，更换adb模式到rndis模式

cd /sys/class/android_usb/android0/

echo 0 > enable //关闭adb模式

echo 0x1111 > idVender

echo ox2222 > idProduct

echo rndis > funtions

echo 1 > enable

如果在操作的过程中忘记命令，就进入：

vinewton-master/out/target/product/newton/root/init.usn.rc

打开init.usn.rc文件，查看adb的模式设置，然后再操作rndis功能模块。



验证的时候需要注意的地方
(1),可能会遇到的情况：

在实际操作的时候会出现ping 板子的IP不能ping通的情况

解决的方法：由于ping得命令是需要经过路由器的，所以，在经过路由器的时候直接就回被路由器截止，所以要验证板子和主机能够形成一个通路的情况就是拔掉网线。当然这个时候可能会出现一种情况是：主机个板子的IP都消失，当然不是真正的消失，此时，需要我们操作的是在root权限下，重新设置IP 主机还有开发板的地址，然后重新验证开发板和主机是否可以正常通信即可。

(2),拔掉网线出现的情况：

在验证通信是否正常的时候，只要是数据可以正常实现相应数据即可。



(2),让开机自动启动修改的配置文件的信息：

cd /home/hwwei/newton-demo/device/ingenic/newton/config

vi init.board.usb.rc

添加：

on property:sys.usb.config=rndis,adb

41 write/sys/class/android_usb/android0/enable 0

42 write/sys/class/android_usb/android0/idVendor 18d1

43 write/sys/class/android_usb/android0/idProduct 4ee7

44 write /sys/class/android_usb/android0/bDeviceClass0

45 write/sys/class/android_usb/android0/bDeviceSubClass 0

46 write/sys/class/android_usb/android0/bDeviceProtocol 0

47 write/sys/class/android_usb/android0/functions ${sys.usb.config}

48 write /sys/class/android_usb/android0/enable1

49 start adbd

50 setprop sys.usb.state ${sys.usb.config}

vi ../device.mk//添加系统默认属性为rndis

PRODUCT_DEFAULT_PROPERTY_OVERRIDES += \

224 persist.sys.usb.config=rndis



cd /home/hwwei/newton-master/out/target/product/newton/root

vi default.prop

将里面的内容修改为：

1 #

2 #ADDITIONAL_DEFAULT_PROPERTIES

3 #

4 ro.secure=1

5ro.allow.mock.location=0

6ro.debuggable=1

7 persist.sys.usb.config=rndis,adb
