我是靠谱客的博主 轻松面包，最近开发中收集的这篇文章主要介绍全志平台华为4G模块开发调试记录1. 前言2. linux部分3. android部分4. 修改ip-up脚本5. 运行huawei-ppp-on脚本6. 查看虚拟网卡7. 查看dns8. 配置dsn9. ping百度10. 通过init.rc进行拨号，觉得挺不错的，现在分享给大家，希望可以做个参考。
概述
以下技术在盈鹏飞嵌入式的A40I/T3核心板(CoM-X40I)和主控板(SBC-X40I)上经过验证,欢迎 交流! CoM-X40I核心板和SBC-X40I主板见下图:
1. 前言
因为需要适配4G模块，这里总结下整个调试过程；
2. linux部分
linux 部分主要是硬件识别，当拿到模块后，插入板子上，打印如下：

从打印可以看出如下信息： （1）USB串口驱动正常工作，设备加载正常。 （2）CDC ECM驱动正常工作。 （3）一共生成了5个虚拟的串口。
3. android部分
3.1 RIL库的移植
在init.rc中添加服务如下：service ril-daemon /system/bin/rild -l libhuawei-ril.so
其中rild源码在/hardware/ril/rild/目录下， 然后将libhuawei-ril.so放到system/lib/目录中，在device/softwinner/common/目录下，新建文件夹LTE/，在该目录中添加文件firmware-LTE.mk， 然后将libhuawei-ril.so文件放入该目录，在firmware-LTE.mk中添加内容如下：
修改device/softwinner/petrel-p1，添加内容如下：
3.2 修改使用的USB或者PCM端口的权限
device/softwinner/petrel-p1目录中，添加如下内容：
3.3 手动测试模组拨号过程
（1）这时候可以借用SDK中PPP源码（对应目录为external/ppp）编译出来的pppoe可执行程序。 首先将部分linux-ppp-script中的相关文件拷贝到SDK中的对应目录，如下：
（2）同时，需要修改huawei-ppp-on脚本，内容如下：
-
#!/bin/sh
-
#
-
# Script to initiate a ppp connection. This is the first part of the
-
# pair of scripts. This is not a secure pair of scripts as the codes
-
# are visible with the 'ps' command. However, it is simple.

5. 运行huawei-ppp-on脚本
sh ./huawei-ppp-on --user=card --pwd=card --pn=*99# --auth=chap --apn=1234 正常情况下打印为：

6. 查看虚拟网卡
执行命令busybox ifconfig，可以看到生成了ppp0网口，如下：
但是此时是无法连接互联网的，因为没有配置dns
7. 查看dns
首先看下通过pppoe报文交互获得dns是什么，利用命令获取如下：getprop | grep dns
-
[
net.-ppp0.dns1]: [
211.136
.20
.203]
-
[
net.-ppp0.dns2]: [
211.136
.17
.107]
8. 配置dsn
-
root@petrel-p1:
/system/etc/ppp
# setprop net.dns1 211.136.20.203
-
root@petrel-p1:
/system/etc/ppp
# setprop net.dns2 211.136.17.107
-
root@petrel-p1:
/system/etc/ppp
# ndc resolver setifdns ppp0 "" 211.136.20.203
-
200
0 Resolver command succeeded
-
root@petrel-p1:
/system/etc/ppp
# ndc resolver setdefaultif ppp0
