其中选择模块的时候一定要注意是否支持中国市场：
ME909s-120, 支持欧洲, 亚太, 拉美等海外市场.
ME909s-821, 支持中国市场
ME909u-521(B1/B2/B3/B5/B7/B8/B20)，欧洲市场
ME909u-523(B2/B4/B5/B13/B17/B25/B26)，北美市场
ME909u-XXX(TBD)，日本市场
再有查看支持的频段，选择相应的联通或移动3G/4G上网卡。

下载：3G/4D 相关文档
三、华为模块Linux 内核驱动集成指导
上述的文档，根据名称都可以自行百度出来。根据指导手册一步一步的来配置内核驱动。
这里只是说的是一些出现的问题：
（1）首先要注意，它所支持的范围：
我们用的是 linux-2.6.32 因为内核版本不同，没有usb_wwan.c usb_wwan.h usb_wwan_write 。所以将添加到上述文件里的内容，合并到option.c中去。
（2）无法加载cmemk.ko irqk.ko edmak.ko等设备模块
是因为版本不同造成的，需要重新编译
下面只操作cmemk.ko 同理irqk.ko edmak.ko
find . -name cmemk.ko
重新编译cmemk.ko
有下图可知，将新编译好的 cmemk.ko 拷贝到
/home/zslf/dm368/rootfs/zslf/rootfs-php/lib/modules/2.6.32.17-davinci1/kernel/drivers/dsp/
然后重新烧写内核，根文件系统，uboot
（3）大小屏不兼容问题
（4）davinci_interrupt 368: VBUS error workaround (delay coming) 与 只有4个ttyUSB 问题
模块使用不当造成的。就是上面所说的使用了欧洲版的模块。
（5）AT 拨号
AT 拨号指令可参看相关手册
先贴出两个OK的3G PPP拨号AT指令
《1》3G OK版ppp-on脚本

APN="3gnet" （而且3gnet，*99#，应该是联通的APN,和拨号号码啊？）

SAY "\nGoodbay\n"先要明白，4G模块有网卡，我们上面整个内核移植过程，EMC移植的网卡驱动。3G用可PPP拨号，但是4G的话，使用网卡。所以接下来是我们经过好几轮实现得出的OK版AT指令。

ARM平台嵌入式Linux下使用3G/4G 模块
原博客已删除，就怕这种事情发生哦，所以我自己写博客从来不会只给一个链接，必须还有标题。
简介
随着工业发展，嵌入式设备接入网络的需求日益增多，在没有有线或者无线以太网的环境下，直接通过3G/4G Modem连接运营商网络来接入互联网不失为一个好方法，本文就着重介绍基于ARM平台的嵌入式设备在Embedded Linux下使用3G/4G Modem的方法。
目前市面上的3G/4G modem和主机的连接方式主要有串口、USB和mini-PCIE，串口模块比较传统且使用比较简单，而mini-PCIE在工业设备中目前应用还不广泛，因此本文使用USB 3G/4G modem来进行演示。
硬件准备
嵌入式平台基于Toradex Colibri i.MX6工业产品级ARM核心板搭配Colibri开发载板，Embedded linux采用Toradex官方发布兼容Yocto Project 的Linux V2.5版本。
3G Modem使用华为 E303s WCDMA Modem，支持中国联通的3G网络
Linux Kernel准备
关于Linux kernel源代码下载及基本编译更新操作请参考这里，本文不再赘述，只简单列出操作如下：
a). 下载Linux kernel源代码
b). 下载安装Toolchain，并link到 “ ~/gcc-linaro “ 目录
$ wget http://releases.linaro.org/14.11/components/toolchain/binaries/arm-linux-gnueabihf/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.tar.xz
$ tar xvf gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.tar.xz
$ ln -s gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf gcc-linaro
c). 设置环境变量
$ export ARCH=arm
$ export PATH=~/gcc-linaro/bin/:$PATH
$ export CROSS_COMPILE=arm-linux-gnueabihf-
d). 配置
$ make colibri_imx6_defconfig
$ make menuconfig //添加下面列出功能
--------------------
[*] Network device support --->
<*> PPP (point-to-point protocol) support
<*> PPP BSD-Compress compression
<*> PPP Deflate compression
[*] PPP filtering
<*> PPP MPPE compression (encryption)
[*] PPP multilink support
<*> PPP over Ethernet
<*> PPP support for async serial ports
<*> PPP support for sync tty ports
[*] USB support --->
<*> USB Modem (CDC ACM) support
[*] USB support --->
<*> USB Serial Converter support --->
<*> USB driver for GSM and CDMA modems
--------------------
e). 重新编译kernel image
$ make -j3 uImage LOADADDR=10008000 2>&1 | tee build.log
f). 升级目标板
根据本章节开始提供的参考升级目标板到新的kernel image
相关软件准备
1). PPP
Toradex image默认已经安装，如果其他ARM平台image也是基于Yocto/OpenEmbedded环境编译，可以在local.conf文件中添加如下选项后编译
-----------------
IMAGE_INSTALL_append = " ppp"
-----------------
2). usb-modesiwtch-2.3.0
a). 需要libusb-1.0.x，先从这里下载源文件并解压
b). 使用上一章节配置的ToolChain如下设置交叉编译libusb
$ sudo CC="/home/xxx/gcc-linaro/bin/arm-linux-gnueabihf-gcc" CXX="/home/xxx/gcc-linaro/bin/arm-linux-gnueabihf-g++" ./configure --host=arm-linux-gnueabihf --prefix=/home/xxx/gcc-linaro --disable-udev
$ make
$ make install
c). 从这里下载usb-modesiwtch并解压
d). 如下修改usb-modesiwtch 目录下Makefile
----------------
CC = ~/gcc-linaro/bin/arm-linux-gnueabihf-gcc
CFLAGS += -Wall -I/home/xxx/gcc-linaro/include -L/home/xxx/gcc-linaro/lib
----------------
e).交叉编译usb-modesiwtch
$ make
f). 从这里下载usb-modeswitch-data，和上面步骤编译出的usb-modesiwtch可执行文件一起上传到目标板
配置Modem连接网络
目前比较新的3G/4G都支持Ethernet模式和Fallback模式，而老一些的模块只支持Fallback模式，请根据所需模块情况自行参考下面操作。
1). Ethernet模式
a). 将E303s 3G Modem连接目标板，由于Modem上包含为了给Windows系统提供驱动而部署的存储分区，Linux默认将设备识别成USB Mass Storage设备

Bus 001 Device 004: ID 12d1:1f01 Huawei Technologies Co., Ltd. E353/E3131 (Mass storage mode)
……
b). 如下修改usb-modeswitch-data-20160112/usb_modeswitch.d目录下的12d1:1f01文件
-----------------------
# Huawei E303s Ethernet Mode
DefaultVendor=0x12d1
DefaultProduct=0x1f01
TargetVendor=0x12d1

MessageEndPoint = "0x01"

------------------------
c). 使用usb-modeswitch工具将modem设置为Ethernet mode
root@colibri-imx6:/home# ./usb_modeswitch -c 12d1:1f01
……

……
d). 查看网络，出现eth1，正确获取ip并连接到网络，下面就可以用使用以太网同样方法使用网络了
root@colibri-imx6:/home# ifconfig
……

……
e). 验证网络连接
root@colibri-imx6:/home# ping www.baidu.com
PING www.baidu.com (61.135.169.121): 56 data bytes

64 bytes from 61.135.169.121: seq=4 ttl=51 time=68.166 ms
2). Fallback模式
有一些较老型号的2G/3G Modem只支持这个模式，无需再用usb-modeswitch转换，可以直接参考下面转换后的操作部分。
a). 如下修改usb-modeswitch-data-20160112/usb_modeswitch.d目录下的12d1:1f01文件
-----------------------
# Huawei E303s Fallback Mode
DefaultVendor=0x12d1
DefaultProduct=0x1f01
TargetVendor=0x12d1
TargetProduct=0x1001
MessageEndPoint = "0x01"

NoDriverLoading=0
------------------------
b). 使用usb-modeswitch工具将modem设置为Fallback mode
root@colibri-imx6:/home# ./usb_modeswitch -c 12d1\:1f01
……

总结
根据上述两种模式的测试结果，第一种Ethernet mode相对速度要更稳定一些，因此对于支持两种模式的modem更建议采用Ethernet mode；另外串口modem使用配置也可以参考Fallback mode。本文虽以E303s为例，但其他3G/4G Modem的配置也是类似，只是需要确定对应模式的Vendor ID，Product ID和Message。
