一、 PPP移植

各項工作具體說明

向Linux核心新增3G模組的驅動(USB轉串列埠驅動)和PPP協定的支援，然後編譯核心並下載到開發板。當然如果之前已經移植好核心,那麼只需要增加幾個選項就可以,然後在編譯核心就可以了,這個文件預設核心已經移植過,所以只講與USB轉串列埠驅動和PPP協定支援的幾個選項。

[linuxidc@localhost linux-3.0]$ make menuconfig

1、USB的驅動要選這幾個：

DeviceDrivers---→

USBsupport---→

<*>USB SerialConverter support--→

[*]USBGeneric Serial Driver

<*>USBdriver for GSM and CDMA modems

2、到此3G模組驅動新增完成，下面進行ppp協定支援的新增（下面所示的幾個選項必選）：

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

完成了這些步驟以後就可以退出make menuconfig進行make編譯核心了。然後再把生成的映象檔案下載到板子上重新啟動開發板即可。然後就會發現在/dev/目錄下生成ppp裝置節點：

~ >: ls -l dev/ppp
crw-rw---- 1 root root 108, 0 Mar 27 17:35 dev/ppp

二、 usb_modeswitch移植

下載usbmode庫：

[linuxidc@localhost fulinux]$ mkdir usbmode
[linuxidc@localhost fulinux]$ cd usbmode/

[linuxidc@localhost usbmode]$ wget http://pkgs.Fedoraproject.org/repo/pkgs/libusb1/libusb-1.0.0.tar.bz2/df2447c23750ef2b4a314200feacc2ee/libusb-1.0.0.tar.bz2

[linuxidc@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

[linuxidc@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

[linuxidc@localhost usbmode]$ wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20130607.tar.bz2

以上這些下載地址如果有失效的，搜尋相應的檔案下載，即可下載。

解壓：

[linuxidc@localhost usbmode]$ tar xjf libusb-1.0.0.tar.bz2
[linuxidc@localhost usbmode]$ tar xjf libusb-compat-0.1.5.tar.bz2
[linuxidc@localhost usbmode]$ tar xjf usb-modeswitch-1.2.6.tar.bz2
[linuxidc@localhost usbmode]$ tar xjf usb-modeswitch-data-20130607.tar.bz2

編譯libusb：

[linuxidc@localhost usbmode]$ mkdir install
[linuxidc@localhost usbmode]$ cd libusb-1.0.0

[linuxidc@localhost libusb-1.0.0]$ ./configure --prefix=/home/linuxidc/fulinux/usbmode/install/ --build=i686 --host=arm-linux --disable-shared --enable-static （注意有兩--的前面有一個空格）

[linuxidc@localhost libusb-1.0.0]$ make

[linuxidc@localhost libusb-1.0.0]$ make install

[linuxidc@localhost libusb-1.0.0]$ ls ../install/
include lib
[linuxidc@localhost libusb-1.0.0]$

編譯usb_modeswitch：

[linuxidc@localhost usbmode]$ cd usb-modeswitch-1.2.6
[linuxidc@localhost usb-modeswitch-1.2.6]$ ls
[linuxidc@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

[linuxidc@localhost libusb-1.0.0]$ cd ..
[linuxidc@localhost usbmode]$ export PKG_CONFIG_PATH=/home/linuxidc/fulinux/usbmode/install/lib/pkgconfig:$PKG_CONFIG_PATH

[linuxidc@localhost usbmode]$ cd libusb-compat-0.1.5
[linuxidc@localhost libusb-compat-0.1.5]$

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

[linuxidc@localhost libusb-compat-0.1.5]$ make

[linuxidc@localhost libusb-compat-0.1.5]$ make install

[linuxidc@localhost libusb-compat-0.1.5]$ ls ../install/
bin include lib
[linuxidc@localhost libusb-compat-0.1.5]$

編譯usb_modeswitch：

[linuxidc@localhost libusb-compat-0.1.5]$ cd ../usb-modeswitch-1.2.4
[linuxidc@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

[linuxidc@localhost usb-modeswitch-1.2.4]$ make
[linuxidc@localhost usb-modeswitch-1.2.4]$ cp usb_modeswitch ../install/bin/

[linuxidc@localhost usb-modeswitch-1.2.4]$ cp usb_modeswitch /tftp/

上面用usb-modeswitch-1.2.6編譯時發現有問題，有如下

[linuxidc@localhost usb-modeswitch-1.2.6]$ make
cc -o usb_modeswitch usb_modeswitch.c -Wall -I../install/include -static -L /home/linuxidc/fulinux/usbmode/install/lib -l usb -l usb-1.0 -l pthread
/usr/bin/ld: skipping incompatible /home/linuxidc/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
[linuxidc@localhost usb-modeswitch-1.2.6]$

“incompatible”庫和這個有衝突。建議使用。1.2.6一下的版本。

把usb-modeswitch-data-20130607下的usb_modeswitch.d中的所有檔案都拷貝到開發板的etc/usb_modeswitch.d/目錄：

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

把usb_modeswitch下載到開發板的/usr/sbin目錄下，把usb_modeswitch.d下載開發板到/etc/目錄下：

/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

交叉編譯好工作原始碼ppp-2.4.4，得到pppd和chat，解壓原始碼包,進入目錄,進行交叉編譯：

[linuxidc@localhost fulinux]$ mkdir ppp
[linuxidc@localhost fulinux]$ cd ppp/
[linuxidc@localhost ppp]$ wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz

[linuxidc@localhost ppp]$ tar zxf ppp-2.4.4.tar.gz
[linuxidc@localhost ppp]$ cd ppp-2.4.4

[linuxidc@localhost ppp-2.4.4]$ ./configure

[linuxidc@localhost chat]$ linux
[linuxidc@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)

[linuxidc@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

[linuxidc@localhost chat]$ cd ../pppd
[linuxidc@localhost pppd]$ vim auth.c

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

[linuxidc@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

[linuxidc@localhost pppd]$ cd ..
[linuxidc@localhost ppp-2.4.4]$ make

make[1]: Leaving directory `/usr/local/src/linuxidc/fulinux/ppp/ppp-2.4.4/pppdump'
[linuxidc@localhost ppp-2.4.4]$ cd chat/
[linuxidc@localhost chat]$ ls
chat chat.8 chat.c chat.o Makefile Makefile.linux Makefile.sol2
[linuxidc@localhost chat]$ file chat
chat: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped

[linuxidc@localhost chat]$ cd ..

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

將交叉編譯出來的這兩個應用程式chat和pppd拷貝到開發板 /usr/sbin目錄下，更改其屬性為可執行檔案。

[linuxidc@localhost chat]$ cp chat /tftp/

[linuxidc@localhost pppd]$ cp pppd /tftp/

在開發板中操作：

~ >: 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

設定撥號的腳檔案

撥號上網需要的組態檔有3個：

wcdma,wcdma-chat-connect,wcdma-chat-disconnect（存放位置是開發板的/etc/ppp/peers）。

~ >: mkdir -p /etc/ppp/peers/

wcdma組態檔內容

# /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組態檔內容

ABORT "ERROR"

ABORT "NO DIALTONE"

SAY "INSending break to the modemn"

""k"

""+++ATH"

SAY "nGood byen"

還要新增一個域名解析的檔案：

nameserver 4.2.2.2

nameserver 8.8.8.8

將上面的四個檔案拷貝到/tftp目錄下。

並下載到開發板相應的目錄中去：

因為

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

到這裡PPP 移植就完成了。

到了這裡大部分工作已經完成了，但是我們的開發板依然不能撥號，還需進一步修改和新增組態檔。

當我們的MF626外掛中興WCDMA USB數據機,Linux核心識別作為一個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

現在我們需要使用usb_modeswitch切換3 g USB數據機來數據機(USB轉換為seiral)，對於usb_modeswitch使用libusb,libusb依賴於USB檔案系統。所以我們在使用usb_modeswitch之前必須掛在usbfs，否則它不能檢測USB裝置。

新增中興WCDMA現代usb_modeswitchMF626組態檔：

~ >: 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"

MessageContent3 = "55534243123456702000000080000c85010101180101010101000000000000"

/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.

這是因為usbfs檔案系統沒有掛在起來，所以使用usb_modeswitch之前要掛載它：
/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

這樣我usbfs就掛載起來了，但是如果重新啟動開發板後，還得重新掛載，為了每次啟動系統都能自動掛載，我們進行如下修改：

~ >: 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
~

現在的話就可以看到如下資訊了：

~ >: usb_modeswitch -c /apps/zte_mf626.conf

Looking for target devices ...

傳送at命令：

~ >: microcom -s 115200 dev/ttyUSB2 （或者~ >: microcom -s 115200 dev/ttyUSB1）

1, 查模組製造商：

at+cgmi
ZTE INCORPORATED

2, 查GPRS模組型號：

at+cgmm
MF626

3, 查模組版本：

at+cgmr
BD_TMOP673M3V1.0.1B07

3, 查SIM卡是否在位：

at+cpin?
+CPIN: READY

4，查GPRS模組信號強度，其中”,”前的數位為信號強度，如下面範例中的12為信號強度。

at+csq
+CSQ: 12,99

若信號強度為99，則無效。我這裡信號強度一般在20左右。

5，查SIM卡是否註冊上網路，其中”,”後的值為SIM卡的註冊狀態，如下面範例中的1.

OK
at+creg?
+CREG: 0,5

OK
如果狀態值為0，表示未註冊；如果為1表示本地號碼註冊上；如果為2，表示正在搜尋運營商註冊，但沒註冊上；3表示拒絕註冊；4，未知狀態； 5，漫遊號碼註冊上。

6，查SIM卡運營商，如下面顯示的”CHN-CUGSM”為中國聯通的號碼：

at+cops?
+COPS: 0,0,"China Mobile Communication Corp.",0

OK
在UC864E模組上，使用AT+COPS?查詢，則聯通的號碼將顯示為”cmnet”，但在GTM900B/C, SIM5215上顯示的是”CHN-CUGSM”. 中國移動的則為”China Mobile”，在現實的時候也有一些區別，例如在UC864E上中國移動顯示為” China Mobile”，當中只有一個空格；而在GTM900B上則顯示” China Mobile”,當中有兩個空格。但是這上面是China Mobile Communication Corp.

8， AT命令打電話，注意在撥的號碼後面有個分號；

atd10086;

我不知道怎麼通電話。

9，如果有電話到來時，則是串列埠上將收到RING字串，這時我們可以使用ATA命令摘機，如果不想接聽，可以使用ATH結束通話；

但是我沒有接到RING。

10，在進行PPP撥號上網前，我們必須使用下面命令來設定APN：

中國移動:

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

中國聯通有兩個APN: uninet和3gnet，如果給3G卡的話，可以設定APN為3gnet

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

AT+CGDCONT?

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

或設定APN為3gnet:

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

AT+CGDCONT?

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

簡訊相關命令：

設定簡訊格式為Text模式：

AT+CMGF=1

設定簡訊格式為PDU模式：

AT+CMGF=0

設定簡訊中心號，一般不需要我們手動設定。

湖北聯通的簡訊中心號設定如下：

AT+CSCA="+8613010360500"

湖北移動的簡訊中心號為：

AT+CSCA?

+CSCA: "+8613800270500",145

現在就可以進行撥號了:

這樣雖然撥號成功，但是它是在前台執行的，現在我們不能進行其他的任何操作，以前前台被它佔領了，所以我們用pppd call wcdma $這個命令讓它在後台執行，這樣我們就可以在前台進行其他的操作了。

可以。

再ping一下百度網：
