本篇文章主要介绍了"ARM+llinux系统移植3G拨号上网收发短信（一）"，主要涉及到ARM+llinux系统移植3G拨号上网收发短信（一）方面的内容，对于ARM+llinux系统移植3G拨号上网收发短信（一）感兴趣的同学可以参考一下。
一、&&&&&&PPP移植
各项工作具体说明
向linux内核添加3G模块的驱动(USB转串口驱动)和PPP协议的支持，然后编译内核并下载到开发板。当然如果之前已经移植好内核,那么只需要增加几个选项就可以,然后在编译内核就可以了,这个文档默认内核已经移植过,所以只讲与USB转串口驱动和PPP协议支持的几个选项。
[ linux-3.0]$ make menuconfig
1、USB的驱动要选这几个：
DeviceDrivers---→
USBsupport---→
&*&USB SerialConverter support--→
[*]USBGeneric Serial Driver&
&*&USBdriver for GSM and CDMA modems
2、到此3G模块驱动添加完成，下面进行ppp协议支持的添加（下面所示的几个选项必选）：
DeviceDrivers--→
Network devicesupport---→
&*&&PPP&(point-to-point&protocol)&support&&&
&&&&&&&&[*]&&&PPP&multilink&support&(EXPERIMENTAL)&&&&
&&&&&&&&&*&&&&PPP&support&for&async&serial&ports&&&&&&
&&&&&&&&&*&&&&PPP&support&for&sync&tty&ports&&&&&&&&&&
&&&&&& &*&&&&PPP&Deflate&compression&&&&&&&&&&&&&&&
&&*&&&&PPP&BSD-Compress&compression&
完成了这些步骤以后就可以退出make menuconfig进行make编译内核了。然后再把生成的镜像文件下载到板子上重启开发板即可。然后就会发现在/dev/目录下生成ppp设备节点：
~ &: ls -l dev/ppp&
crw-rw---- & &1 root & & root & & &108, & 0 Mar 27 17:35 dev/ppp

二、&&&&& usb_modeswitch移植
下载usbmode库：
[ fulinux]$ mkdir usbmode
[ fulinux]$ cd usbmode/
[ usbmode]$ wget http://pkgs.fedoraproject.org/repo/pkgs/libusb1/libusb-1.0.0.tar.bz2/dfef2b4a314200feacc2ee/libusb-1.0.0.tar.bz2
[ usbmode]$ wget http://jaist.dl.sourceforge.net/project/libusb/libusb-compat-0.1/libusb-compat-0.1.5/libusb-compat-0.1.5.tar.bz2
[ usbmode]$wget http://pkgs.fedoraproject.org/repo/pkgs/usb_modeswitch/usb-modeswitch-1.2.4.tar.bz2/dbd4cea5a64d/usb-modeswitch-1.2.4.tar.bz2
[ usbmode]$ wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-.tar.bz2
以上这些下载地址如果有失效的，搜索相应的文件下载，即可下载。
[ usbmode]$ tar xjf libusb-1.0.0.tar.bz2&
[ usbmode]$ tar xjf libusb-compat-0.1.5.tar.bz2&
[ usbmode]$ tar xjf usb-modeswitch-1.2.6.tar.bz2&
[ usbmode]$ tar xjf usb-modeswitch-data-.tar.bz2&
编译libusb：
[ usbmode]$ mkdir install
[ usbmode]$ cd libusb-1.0.0
[ libusb-1.0.0]$ ./configure --prefix=/home/lingyun/fulinux/usbmode/install/ &--build=i686 --host=arm-linux &--disable-shared --enable-static & &（注意有两--的前面有一个空格）
[ libusb-1.0.0]$ make
[ libusb-1.0.0]$ make install
[ libusb-1.0.0]$ ls ../install/
include &lib
[ libusb-1.0.0]$&
编译usb_modeswitch：
[ usbmode]$ cd usb-modeswitch-1.2.6
[ usb-modeswitch-1.2.6]$ ls
[ usb-modeswitch-1.2.6]$ vim Makefile&
CC & & & & &?=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc #addr fulinux
CFLAGS & & &+= -Wall -l ../install/include-static #add by fulinux
LIBS & & & &= -L ../install/lib/ -l usb -l usb-1.0-l pthread & #add by fulinux
[ libusb-1.0.0]$ cd ..
[ usbmode]$ export PKG_CONFIG_PATH=/home/lingyun/fulinux/usbmode/install/lib/pkgconfig:$PKG_CONFIG_PATH
[ usbmode]$ cd libusb-compat-0.1.5
[ libusb-compat-0.1.5]$&
[ libusb-compat-0.1.5]$ ./configure --prefix=/home/lingyun/fulinux/usbmode/install/ &--build=i686 --host=arm-linux
--disable-shared --enable-static
[ libusb-compat-0.1.5]$ make&
[ libusb-compat-0.1.5]$ make install
[ libusb-compat-0.1.5]$ ls ../install/
bin &include &lib
[ libusb-compat-0.1.5]$&
编译usb_modeswitch：
[ libusb-compat-0.1.5]$ cd ../usb-modeswitch-1.2.4
[ usb-modeswitch-1.2.6]$ vim Makefile&
CC & & & & &= /opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc
CFLAGS & & &+= -Wall -I ../install/include -static
LIBS & & & &= -L ../install/lib -l usb -l usb-1.0 -l pthread
[ usb-modeswitch-1.2.4]$ make
[ usb-modeswitch-1.2.4]$ cp usb_modeswitch ../install/bin/
[ usb-modeswitch-1.2.4]$ cp usb_modeswitch /tftp/
上面用usb-modeswitch-1.2.6编译时发现有问题，有如下
[ usb-modeswitch-1.2.6]$ make
cc -o usb_modeswitch usb_modeswitch.c -Wall -I../install/include -static &-L /home/lingyun/fulinux/usbmode/install/lib -l usb -l usb-1.0 -l pthread&
/usr/bin/ld: skipping incompatible /home/lingyun/fulinux/usbmode/install/lib/libusb.a when searching for -lusb
/usr/bin/ld: cannot find -lusb
collect2: ld returned 1 exit status
make: *** [usb_modeswitch] Error 1
[ usb-modeswitch-1.2.6]$&
“incompatible”库和这个有冲突。建议使用。1.2.6一下的版本。
把usb-modeswitch-data-下的usb_modeswitch.d中的所有文件都拷贝到开发板的etc/usb_modeswitch.d/目录：
usbmode]$ cd usb-modeswitch-data-
[ usb-modeswitch-data-]$ ls
40-usb_modeswitch.rules &ChangeLog &COPYING &gen-rules.tcl &Makefile &README &usb_modeswitch.d
[ usb-modeswitch-data-]$ tar cjf usb_modeswitch.d.tar.bz2 usb_modeswitch.d/
[ usb-modeswitch-data-]$ ls
40-usb_modeswitch.rules &ChangeLog &COPYING &gen-rules.tcl &Makefile &README &usb_modeswitch.d &usb_modeswitch.d.tar.bz2
[ usb-modeswitch-data-]$ cp usb_modeswitch.d.tar.bz2 /tftp/
[ usb-modeswitch-data-]$&
把usb_modeswitch下载到开发板的/usr/sbin目录下，把usb_modeswitch.d下载开发板到/etc/目录下：
/usr/sbin &: tftp -gr usb_modeswitch 192.168.1.3
usb_modeswitch & & & 100% |*******************************| & 390k &0:00:00 ETA
/etc &: tftp -gr usb_modeswitch.d.tar.bz2 192.168.1.3
usb_modeswitch.d.tar 100% |*******************************| &8741 & 0:00:00 ETA
/etc &: tar xjf usb_modeswitch.d.tar.bz2
三、pppd和chat
交叉编译好工作源代码ppp-2.4.4，得到pppd和chat，解压源代码包,进入目录,进行交叉编译：
[ fulinux]$ mkdir ppp
[ fulinux]$ cd ppp/
[ ppp]$ wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz
[ ppp]$ tar zxf ppp-2.4.4.tar.gz&
[ ppp]$ cd ppp-2.4.4
[ ppp-2.4.4]$ ./configure
[ chat]$ linux
[ chat]$ vim chat.c
1168 & & if (timeout_next) {
1169 & & timeout_next = 0;
1171 & & s = clean(s,0); /* add by fulinux */
1173 & & timeout = atoi(s);
1175 & & free(s); & &/* add by fulinux */
1177 & & if (timeout &= 0)
[ chat]$ vim Makefile
INSTALL= install
CC=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc #add by fulinux
all: & &chat
chat: & chat.o
& & $(CC) -static -o chat chat.o #add by fulinux
[ chat]$ cd ../pppd
[ pppd]$ vim auth.c&
1316 & & ao-&neg_upap = !refuse_pap /*&& (passwd[0] != 0 || get_pap_passwd(NULL))*/; /* add by fulinux*/
[ pppd]$ vim Makefile
&33 CC = /opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc # add by fulinux
&46#MPPE=y
&51#FILTER=y
&68#PLUGIN=y
[ pppd]$ cd ..
[ ppp-2.4.4]$ make
make[1]: Leaving directory `/usr/local/src/lingyun/fulinux/ppp/ppp-2.4.4/pppdump'
[ ppp-2.4.4]$ cd chat/
[ chat]$ ls
chat&chat.8 &chat.c &chat.o &Makefile
&Makefile.linux &Makefile.sol2
[ chat]$ file chat
chat: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped
[ chat]$ cd ..
[ ppp-2.4.4]$ cd pppd
[ pppd]$ file pppd
pppd: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
将交叉编译出来的这两个应用程序chat和pppd拷贝到开发板&/usr/sbin目录下，更改其属性为可执行文件。
[ chat]$ cp chat /tftp/
[ pppd]$ cp pppd /tftp/
在开发板中操作：
~ &: cd usr/sbin/
/usr/sbin &: tftp -gr chat 192.168.1.3
chat & & & & & & & & 100% |*******************************| & 147k &0:00:00 ETA
/usr/sbin &: tftp -gr pppd 192.168.1.3
pppd & & & & & & & & 100% |*******************************| & 621k &0:00:00 ETA
/usr/sbin &: chmod a+x chat
/usr/sbin &: chmod a+x pppd
配置拨号的脚文件
拨号上网需要的配置文件有3个：
wcdma,wcdma-chat-connect,wcdma-chat-disconnect（存放位置是开发板的/etc/ppp/peers）。
~ &: mkdir -p /etc/ppp/peers/
wcdma配置文件内容
# /etc/ppp/peers/wcdma
# This is pppd script for China liantong
# Usage: root&pppd call cdma
hide-password
connect '/usr/sbin/chat -s -v -f /etc/ppp/peers/wcdma-chat-connect'
disconnect '/usr/sbin/chat -s -v -f /etc/ppp/peers/wcdma-chat-disconnect'
/dev/ttyUSB2
defaultroute
noipdefault
ipcp-accept-local
ipcp-accept-remote
user&card&
password&card&
remotename 3gppp
ipparam 3gppp
usepeerdns
wcdma-chat-connect配置文件内容
ABORT &BUSY&
ABORT &NO CARRIER&
ABORT &NO DIALTONE&
ABORT &ERROR&
ABORT &NO ANSWER&
TIMEOUT 120
OK \rAT+CGDCONT=1,&IP&,&3gnet&,,0,0
OK-AT-OK ATDT*99#
CONNECT \d\c
wcdma-chat-disconnect配置文件内容
ABORT &ERROR&
ABORT &NO DIALTONE&
SAY &INSending break to the modem\n&
&&+++ATH&
SAY &\nGood bye\n&
还要添加一个域名解析的文件：
nameserver 4.2.2.2
nameserver 8.8.8.8
将上面的四个文件拷贝到/tftp目录下。
并下载到开发板相应的目录中去：
lrwxrwxrwx & &1 root & & root & & & & & &29 Apr 21 &2013 resolv.conf -& /apps/etc/network/resolv.conf
/apps/etc/network &: tftp -gr resolv.conf 192.168.1.3
~ &: cd etc/ppp/peers/
/etc/ppp/peers &: ls
/etc/ppp/peers &: tftp -gr wcdma 192.168.1.3
/etc/ppp/peers &: tftp -gr wcdma-chat-disconnect 192.168.1.3
/etc/ppp/peers &: tftp -gr wcdma-chat-connect 192.168.1.3
/etc/ppp/peers &: ls
wcdma & & & & & & & & &wcdma-chat-connect & & wcdma-chat-disconnect
到这里PPP 移植就完成了。
到了这里大部分工作已经完成了，但是我们的开发板依然不能拨号，还需进一步修改和添加配置文件。
当我们的MF626插件中兴WCDMA USB调制解调器,Linux内核识别作为一个cd – rom。
scsi0 :usb-storage 1-1.4:1.0
scsi 0:0:0:0:&CD-ROM&&&&&&&&&&&&ZTE&&&&& USB SCSI CD-ROM& 2.31 PQ: 0 ANSI: 2
现在我们需要使用usb_modeswitch切换3 g USB调制解调器来调制解调器(USB转换为seiral)，对于usb_modeswitch使用libusb,libusb依赖于USB文件系统。所以我们在使用usb_modeswitch之前必须挂在usbfs，否则它不能检测USB设备。
添加中兴WCDMA现代usb_modeswitchMF626配置文件：
~ &: cd apps/
/apps &: vi zte_mf626.conf
#ZTE devices
DefaultVendor = 0x19d2
DefaultProduct= 0x2000
TargetVendor &= 0x19d2
TargetProdduct= &15,31,63,91,28,03&
MessageContent = &000&
MessageContent2 = &000&
MessageContent3 = &00&
NeedResponse=1
/apps &: ls
etc & & & & & & zte_mf626.conf
/apps &: usb_modeswitch -c /apps/zte_mf626.conf&
Looking for target devices ...
&No devices in target mode or class found
Looking for default devices ...
&No devices in default mode found. Nothing to do. Bye.
这是因为usbfs文件系统没有挂在起来，所以使用usb_modeswitch之前要挂载它：
/apps &: mount -tusbfs usbfs /proc/bus/usb/
/apps &: mount
rootfs on / type rootfs (rw)
/dev/root on / type jffs2 (rw,relatime)
proc on /proc type proc (rw,relatime)
usbfs on /proc/bus/usb type usbfs (rw,relatime)
tmpfs on /dev type tmpfs (rw,relatime)
ramfs on /tmp type ramfs (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
ubi7:apps on /apps type ubifs (rw,sync,noatime)
/dev/mtdblock8 on /data type jffs2 (rw,sync,noatime)
~ &: ls proc/bus/usb/
001 & & &devices
这样我usbfs就挂载起来了，但是如果重启开发板后，还得重新挂载，为了每次启动系统都能自动挂载，我们进行如下修改：
~ &: cd etc/
/etc &: vim fstab&
# /etc/fstab: static file system information.
# &file system& &mount pt& & & &type& & &options& & & & & &dump& &pass&
/dev/root & & & / & & & & & & &ext2 & & rw,noauto & & & & 0 & & &1
proc & & & & & &/proc & & & & &proc & & defaults & & & & &0 & & &0
usbfs & & & & & /proc/bus/usb &usbfs & &defaults & & & & &0 & & &0
tmpfs & & & & & /dev & & & & & tmpfs & &defaults & & & & &0 & & &0
ramfs & & & & & /tmp & & & & & ramfs & &defaults & & & & &0 & & &0
sysfs & & & & & /sys & & & & & sysfs & &defaults & & & & &0 & & &0
现在的话就可以看到如下信息了：
~ &: usb_modeswitch -c /apps/zte_mf626.conf&
Looking for target devices ...
&No devices in target mode or class found
Looking for default devices ...
& &found matching product ID

查模块制造商：
at+cgmi
ZTE INCORPORATED
2,& 查GPRS模块型号：
at+cgmm
3,& 查模块版本：
at+cgmr
BD_TMOP673M3V1.0.1B07
3,& 查SIM卡是否在位：
at+cpin?
+CPIN: READY
4，查GPRS模块信号强度，其中”,”前的数字为信号强度，如下面示例中的12为信号强度。
at+csq
+CSQ: 12,99
若信号强度为99，则无效。我这里信号强度一般在20左右。
5，查SIM卡是否注册上网络，其中”,”后的值为SIM卡的注册状态，如下面示例中的1.
at+creg?
+CREG: 0,5
如果状态值为0，表示未注册；如果为1表示本地号码注册上；如果为2，表示正在搜索运营商注册，但没注册上；3表示拒绝注册；4，未知状态； 5， 漫游号码注册上。
6，查SIM卡运营商，如下面显示的”CHN-CUGSM”为中国联通的号码：
at+cops?
+COPS: 0,0,&China Mobile Communication Corp.&,0
在UC864E模块上，使用AT+COPS?查询，则联通的号码将显示为”cmnet”，但在GTM900B/C, SIM5215上显示的是”CHN-CUGSM”. 中国移动的则为”China Mobile”，在现实的时候也有一些区别，例如在UC864E上中国移动显示为” China Mobile”，当中只有一个空格；而在GTM900B上则显示” China & Mobile”,当中有两个空格。但是这上面是China Mobile Communication
8， AT命令打电话，注意在拨的号码后面有个分号；
&我不知道怎么通电话。
9，如果有电话到来时，则是串口上将收到RING字符串，这时我们可以使用ATA命令摘机，如果不想接听，可以使用ATH挂断；
&但是我没有接到RING。
10，在进行PPP拨号上网前，我们必须使用下面命令来设置APN：
AT+CGDCONT=1,&IP&,&cmnet&
中国联通有两个APN:& uninet和3gnet， 如果给3G卡的话，可以设置APN为3gnet
AT+CGDCONT=1,&IP&,&uninet&
AT+CGDCONT?
+CGDCONT:1,&IP&,&uninet&,&0.0.0.0&,0,0
或设置APN为3gnet:
AT+CGDCONT=1,&IP&,&3gnet&
AT+CGDCONT?
+CGDCONT:1,&IP&,&3gnet&,&0.0.0.0&,0,0
短信相关命令：
设置短信格式为Text模式：
AT+CMGF=1&&
设置短信格式为PDU模式：
AT+CMGF=0
设置短信中心号，一般不需要我们手动设置。
湖北联通的短信中心号设置如下：
AT+CSCA=&+0&
湖北移动的短信中心号为：
AT+CSCA?
+CSCA: &+0&,145
现在就可以进行拨号了:
