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。
[lingyun@localhost 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：
[lingyun@localhost fulinux]$ mkdir usbmode
[lingyun@localhost fulinux]$ cd usbmode/
[lingyun@localhost usbmode]$ wget http://pkgs.fedoraproject.org/repo/pkgs/libusb1/libusb-1.0.0.tar.bz2/df2447c23750ef2b4a314200feacc2ee/libusb-1.0.0.tar.bz2
[lingyun@localhost 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
[lingyun@localhost usbmode]$wget http://pkgs.fedoraproject.org/repo/pkgs/usb_modeswitch/usb-modeswitch-1.2.4.tar.bz2/dbd4ce7966d7b4a5a0604a8280f7164d/usb-modeswitch-1.2.4.tar.bz2
[lingyun@localhost usbmode]$ 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：
[lingyun@localhost usbmode]$ tar xjf libusb-1.0.0.tar.bz2
[lingyun@localhost usbmode]$ tar xjf libusb-compat-0.1.5.tar.bz2
[lingyun@localhost usbmode]$ tar xjf usb-modeswitch-1.2.6.tar.bz2
[lingyun@localhost usbmode]$ tar xjf usb-modeswitch-data-20130607.tar.bz2
编译libusb：
[lingyun@localhost usbmode]$ mkdir install
[lingyun@localhost usbmode]$ cd libusb-1.0.0
[lingyun@localhost 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）
[lingyun@localhost libusb-1.0.0]$ make
[lingyun@localhost libusb-1.0.0]$ make install
[lingyun@localhost libusb-1.0.0]$ ls ../install/
include lib
[lingyun@localhost libusb-1.0.0]$
编译usb_modeswitch：
[lingyun@localhost usbmode]$ cd usb-modeswitch-1.2.6
[lingyun@localhost usb-modeswitch-1.2.6]$ ls
[lingyun@localhost 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
[lingyun@localhost libusb-1.0.0]$ cd ..
[lingyun@localhost usbmode]$ export PKG_CONFIG_PATH=/home/lingyun/fulinux/usbmode/install/lib/pkgconfig:$PKG_CONFIG_PATH
[lingyun@localhost usbmode]$ cd libusb-compat-0.1.5
[lingyun@localhost libusb-compat-0.1.5]$
[lingyun@localhost libusb-compat-0.1.5]$ ./configure --prefix=/home/lingyun/fulinux/usbmode/install/ --build=i686 --host=arm-linux --disable-shared --enable-static
[lingyun@localhost libusb-compat-0.1.5]$ make
[lingyun@localhost libusb-compat-0.1.5]$ make install
[lingyun@localhost libusb-compat-0.1.5]$ ls ../install/
bin include lib
[lingyun@localhost libusb-compat-0.1.5]$
编译usb_modeswitch：
[lingyun@localhost libusb-compat-0.1.5]$ cd ../usb-modeswitch-1.2.4
[lingyun@localhost 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
[lingyun@localhost usb-modeswitch-1.2.4]$ make
[lingyun@localhost usb-modeswitch-1.2.4]$ cp usb_modeswitch ../install/bin/
[lingyun@localhost 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
[lingyun@localhost 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
[lingyun@localhost 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：
[lingyun@localhost usbmode]$ cd usb-modeswitch-data-20130607
[lingyun@localhost usb-modeswitch-data-20130607]$ ls
40-usb_modeswitch.rules ChangeLog COPYING gen-rules.tcl Makefile README usb_modeswitch.d
[lingyun@localhost usb-modeswitch-data-20130607]$ tar cjf usb_modeswitch.d.tar.bz2 usb_modeswitch.d/
[lingyun@localhost usb-modeswitch-data-20130607]$ ls
40-usb_modeswitch.rules ChangeLog COPYING gen-rules.tcl Makefile README usb_modeswitch.d usb_modeswitch.d.tar.bz2
[lingyun@localhost usb-modeswitch-data-20130607]$ cp usb_modeswitch.d.tar.bz2 /tftp/
[lingyun@localhost 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：
[lingyun@localhost fulinux]$ mkdir ppp
[lingyun@localhost fulinux]$ cd ppp/
[lingyun@localhost ppp]$ wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz
[lingyun@localhost ppp]$ tar zxf ppp-2.4.4.tar.gz
[lingyun@localhost ppp]$ cd ppp-2.4.4
[lingyun@localhost ppp-2.4.4]$ ./configure
[lingyun@localhost chat]$ linux
[lingyun@localhost 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)
[lingyun@localhost chat]$ vim Makefile
INSTALL= install
CC=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc #add by fulinux
all: chat
chat: chat.o
$(CC) -static -o chat chat.o #add by fulinux
[lingyun@localhost chat]$ cd ../pppd
[lingyun@localhost pppd]$ vim auth.c
1316 ao->neg_upap = !refuse_pap /*&& (passwd[0] != 0 || get_pap_passwd(NULL))*/; /* add by fulinux*/
[lingyun@localhost 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
[lingyun@localhost pppd]$ cd ..
[lingyun@localhost ppp-2.4.4]$ make
make[1]: Leaving directory `/usr/local/src/lingyun/fulinux/ppp/ppp-2.4.4/pppdump'
[lingyun@localhost ppp-2.4.4]$ cd chat/
[lingyun@localhost chat]$ ls
chat chat.8 chat.c chat.o Makefile Makefile.linux Makefile.sol2
[lingyun@localhost chat]$ file chat
chat: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped
[lingyun@localhost chat]$ cd ..
[lingyun@localhost ppp-2.4.4]$ cd pppd
[lingyun@localhost pppd]$ file pppd
pppd: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
[lingyun@localhost 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。
[lingyun@localhost chat]$ cp chat /tftp/
[lingyun@localhost 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
noauth
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'

wcdma-chat-disconnect配置文件内容
ABORT "ERROR"
ABORT "NO DIALTONE"
SAY "INSending break to the modem\n"
""\k"
""+++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：
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

MessageContent3 = "55534243123456702000000080000c85010101180101010101000000000000"

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

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

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
