二、相关文档

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

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。

int main(int argc,const char* argv[]){int ret = 0;printf("### Serial_ttyUSB0_Init ###\n");ret = Serial_ttyUSB0_Init();if(-1 == ret){printf("### Failed to Serial_ttyUSB0_Init ###\n");return -1;}printf("### Serial_ttyUSB0_Init End ###\n");int CFUNFlag = 0;while(!CFUNFlag){printf("###  MU909_SetCFUN ###\n");ret = MU909_SetCFUN(fd_serial,1);if(-1 == ret){CFUNFlag = 0;}else{CFUNFlag = 1;}}unsigned char * strCGACTCommand1 = "AT+CMEE=2\r";int CGACTFlag1 = 0;while(!CGACTFlag1){ret = ME3760_CGACT(fd_serial,strCGACTCommand1);if(-1 == ret){CGACTFlag1 = 0;}else{CGACTFlag1 = 1;}}unsigned char * strCGACTCommand2 = "AT+CPIN?\r";int CGACTFlag2 = 0;while(!CGACTFlag2){ret = ME3760_CGACT(fd_serial,strCGACTCommand2);if(-1 == ret){CGACTFlag2 = 0;}else{CGACTFlag2 = 1;}}unsigned char * strCGACTCommand3 = "AT+CEREG=2\r";int CGACTFlag3 = 0;while(!CGACTFlag3){ret = ME3760_CGACT(fd_serial,strCGACTCommand3);if(-1 == ret){CGACTFlag3 = 0;}else{CGACTFlag3 = 1;}}unsigned char * strCGACTCommand4 = "AT^HCSQ?\r";int CGACTFlag4 = 0;while(!CGACTFlag4){ret = ME3760_CGACT(fd_serial,strCGACTCommand4);if(-1 == ret){CGACTFlag4 = 0;}else{CGACTFlag4 = 1;}}unsigned char * strCGACTCommand5 = "AT+COPS?\r";int CGACTFlag5 = 0;while(!CGACTFlag5){ret = ME3760_CGACT(fd_serial,strCGACTCommand5);if(-1 == ret){CGACTFlag5 = 0;}else{CGACTFlag5 = 1;}}unsigned char * strSysConfigArguments6 = "AT^SYSCFGEX=\"03\",3fffffff,1,2,7fffffffffffffff,,\r"; int SysConfigFlag6 = 0;while(!SysConfigFlag6){ret = MU909_SysConfig(fd_serial,strSysConfigArguments6);if(-1 == ret){SysConfigFlag6 = 0;}else{SysConfigFlag6 = 1;}}unsigned char * strCGACTCommand7 = "AT^NDISDUP=1,1,\"cmnet\"\r";int CGACTFlag7 = 0;while(!CGACTFlag7){ret = ME3760_CGACT(fd_serial,strCGACTCommand7);if(-1 == ret){CGACTFlag7 = 0;}else{CGACTFlag7 = 1;}}system("udhcpc -i usb0");Serial_ttyUSB0_Release();return 0;}

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
