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。

[[email protected] 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：

[[email protected] fulinux]$ mkdir usbmode
[[email protected] fulinux]$ cd usbmode/

[[email protected] usbmode]$ wget http://pkgs.fedoraproject.org/repo/pkgs/libusb1/libusb-1.0.0.tar.bz2/df2447c23750ef2b4a314200feacc2ee/libusb-1.0.0.tar.bz2

[[email protected] 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

[[email protected] usbmode]$wget http://pkgs.fedoraproject.org/repo/pkgs/usb_modeswitch/usb-modeswitch-1.2.4.tar.bz2/dbd4ce7966d7b4a5a0604a8280f7164d/usb-modeswitch-1.2.4.tar.bz2

[[email protected] usbmode]$ wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20130607.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。

解压：

[[email protected] usbmode]$ tar xjf libusb-1.0.0.tar.bz2 
[[email protected] usbmode]$ tar xjf libusb-compat-0.1.5.tar.bz2 
[[email protected] usbmode]$ tar xjf usb-modeswitch-1.2.6.tar.bz2 
[[email protected] usbmode]$ tar xjf usb-modeswitch-data-20130607.tar.bz2 

编译libusb：

[[email protected] usbmode]$ mkdir install
[[email protected] usbmode]$ cd libusb-1.0.0

[[email protected] 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）

[[email protected] libusb-1.0.0]$ make

[[email protected] libusb-1.0.0]$ make install

[[email protected] libusb-1.0.0]$ ls ../install/
include  lib
[[email protected] libusb-1.0.0]$ 

编译usb_modeswitch：

[[email protected] usbmode]$ cd usb-modeswitch-1.2.6
[[email protected] usb-modeswitch-1.2.6]$ ls
[[email protected] 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

[[email protected] libusb-1.0.0]$ cd ..
[[email protected] usbmode]$ export PKG_CONFIG_PATH=/home/lingyun/fulinux/usbmode/install/lib/pkgconfig:$PKG_CONFIG_PATH

[[email protected] usbmode]$ cd libusb-compat-0.1.5
[[email protected] libusb-compat-0.1.5]$ 

[[email protected] libusb-compat-0.1.5]$ ./configure --prefix=/home/lingyun/fulinux/usbmode/install/  --build=i686 --host=arm-linux --disable-shared --enable-static

[[email protected] libusb-compat-0.1.5]$ make 

[[email protected] libusb-compat-0.1.5]$ make install

[[email protected] libusb-compat-0.1.5]$ ls ../install/
bin  include  lib
[[email protected] libusb-compat-0.1.5]$ 

编译usb_modeswitch：

[[email protected] libusb-compat-0.1.5]$ cd ../usb-modeswitch-1.2.4
[[email protected] 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

[[email protected] usb-modeswitch-1.2.4]$ make
[[email protected] usb-modeswitch-1.2.4]$ cp usb_modeswitch ../install/bin/

[[email protected] 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

[[email protected] 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
[[email protected] 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-20130607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：

[[email protected] usbmode]$ cd usb-modeswitch-data-20130607
[[email protected] usb-modeswitch-data-20130607]$ ls
40-usb_modeswitch.rules  ChangeLog  COPYING  gen-rules.tcl  Makefile  README  usb_modeswitch.d
[[email protected] usb-modeswitch-data-20130607]$ tar cjf usb_modeswitch.d.tar.bz2 usb_modeswitch.d/
[[email protected] usb-modeswitch-data-20130607]$ ls
40-usb_modeswitch.rules  ChangeLog  COPYING  gen-rules.tcl  Makefile  README  usb_modeswitch.d  usb_modeswitch.d.tar.bz2
[[email protected] usb-modeswitch-data-20130607]$ cp usb_modeswitch.d.tar.bz2 /tftp/
[[email protected] usb-modeswitch-data-20130607]$ 

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：

[[email protected] fulinux]$ mkdir ppp
[[email protected] fulinux]$ cd ppp/
[[email protected] ppp]$ wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz

[[email protected] ppp]$ tar zxf ppp-2.4.4.tar.gz 
[[email protected] ppp]$ cd ppp-2.4.4

[[email protected] ppp-2.4.4]$ ./configure

[[email protected] chat]$ linux
[[email protected] chat]$ vim chat.c

1168     if (timeout_next) {
1169     timeout_next = 0;
1170     
1171     s = clean(s,0); /* add by fulinux */
1172     
1173     timeout = atoi(s);
1174     
1175     free(s);    /* add by fulinux */
1176     
1177     if (timeout <= 0)

[[email protected] 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

[[email protected] chat]$ cd ../pppd
[[email protected] pppd]$ vim auth.c 

1316     ao->neg_upap = !refuse_pap /*&& (passwd[0] != 0 || get_pap_passwd(NULL))*/; /* add by fulinux*/

[[email protected] 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

[[email protected] pppd]$ cd ..
[[email protected] ppp-2.4.4]$ make

make[1]: Leaving directory `/usr/local/src/lingyun/fulinux/ppp/ppp-2.4.4/pppdump‘
[[email protected] ppp-2.4.4]$ cd chat/
[[email protected] chat]$ ls
chat chat.8  chat.c  chat.o  Makefile  Makefile.linux  Makefile.sol2
[[email protected] chat]$ file chat

[[email protected] chat]$ cd ..

[[email protected] ppp-2.4.4]$ cd pppd
[[email protected] pppd]$ file pppd
pppd: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
[[email protected] pppd]$ 

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。

[[email protected] chat]$ cp chat /tftp/

[[email protected] 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

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
"" AT
OK \rATZ
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"

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：

因为

lrwxrwxrwx    1 root     root            29 Apr 21  2013 resolv.conf -> /apps/etc/network/resolv.conf

所以：

/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= "0001,0002,0015,0016,0017,0031,0052,0055,0063,0064,0066,0091,0108,0117,0128,0157,2002,2003"
 
 
MessageContent = "5553424312345678000000000000061e000000000000000000000000000000"
 
MessageContent2 = "5553424312345679000000000000061b000000020000000000000000000000"
 
MessageContent3 = "55534243123456702000000080000c85010101180101010101000000000000"
 
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)
/apps >: 

~ >: 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

at

OK

1,  查模块制造商：

at+cgmi
ZTE INCORPORATED

OK

2,  查GPRS模块型号：

at+cgmm
MF626

OK

3,  查模块版本：

at+cgmr
BD_TMOP673M3V1.0.1B07

OK

3,  查SIM卡是否在位：

at+cpin?
+CPIN: READY

OK

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

OK

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.

OK
at+creg?
+CREG: 0,5

OK

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

OK

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 Corp.

8， AT命令打电话，注意在拨的号码后面有个分号；

atd10086;

OK

 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：

中国移动:

AT+CGDCONT=1,"IP","cmnet"

OK

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"

OK

AT+CGDCONT?

+CGDCONT:1,"IP","uninet","0.0.0.0",0,0

OK

或设置APN为3gnet:

AT+CGDCONT=1,"IP","3gnet"

OK

AT+CGDCONT?

+CGDCONT:1,"IP","3gnet","0.0.0.0",0,0

OK

短信相关命令：

设置短信格式为Text模式：

AT+CMGF=1  

OK

设置短信格式为PDU模式：

AT+CMGF=0

OK

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="+8613010360500"

OK

湖北移动的短信中心号为：

AT+CSCA?

+CSCA: "+8613800270500",145

OK

现在就可以进行拨号了:

这样虽然拨号成功，但是它是在前台运行的，现在我们不能进行其他的任何操作，以前前台被它占领了，所以我们用pppd call wcdma $这个命令让它在后台运行，这样我们就可以在前台进行其他的操作了。

三、          现在我们就来测试一下，看看能不能上网

ping 域名服务器4.2.2.2

/etc/ppp/peers >: ping 4.2.2.2 -I ppp0

可以。

再ping一下百度网：

/etc/ppp/peers >: ping www.baidu.com -I ppp0
