Huawei E180 3G模块驱动应用

杂谈

3G modem:

Huawei E180（WCDMA）

3G SIM Card：

China Unicom 3G Card（WO）

CPU/Board

FSL P1022DS RevC board

Linux：

Linux-2.6.35

1.

向linux内核中添加3G模块的驱动（USB转串口的驱动）和PPP协议的支持

2.

下载ppp-2.4.5源码并进行交叉编译（toolchian：powerpc-linux-）。

将拨号上网所需的两个应用程序pppd和chat拷贝到开发板/usr/sbin文件夹下。

将改好的脚本文件ppp-on,ppp-on-dialer存放在/etc/ppp目录下。

将含有域名解析服务器地址的文件resolv.conf拷贝到/etc目录下。

3.

进入 /etc/ppp 目录 ，执行 ./ppp-on。 进行网络测试
