华为3G网卡E1750在omap3530上移植.doc

一、环境1、 开发板内核：linux-2.6.28-omap2、 3G卡片：华为E1750二、相关工具1 usb-modeswitch-1.0.2.tar.bz2usb_modeswitch这个工具来进行3G模式转换2 libusb-0.1.12.tar.gzlibusb提供给usb_modeswitch一套系统API三、交叉编译1交叉编译libusb解压并进入libusb-0.1.12目录，建立子目录install用于存放最后生存的库文件与头文件。rootlibusb-0.1.12# mkdir install配置并生成Makefile文件rootlibusb-0.1.12# ./configure -build=i686-linux -host=arm-none-linux-gnueabi -prefix=/home/libusb-0.1.12/install rootlibusb-0.1.12# make rootlibusb-0.1.12# make install（我的交叉编译器是arm-none-linux-gnueabi，你的可能是arm-linux）2. 交叉编译usb_modeswitch（1）修改Makefile文件 CC = arm-none-linux-gnueabi（2）将libusb里的库头文件拷到交叉编译器的include和lib目录下（3）make（4）修改usb_modeswitch-1.0.2目录下的usb_modeswitch.conf文件# Huawei E1750DefaultVendor= 0x12d1DefaultProduct= 0x1446TargetVendor= 0x12d1TargetProduct= 0x1001# only for reference and 0.x versionsMessageEndpoint=0x01MessageContent=55534243123456780000000000000011060000000000000000000000000000HuaweiMode=03. 将上面生成的libusb动态库拷贝到文件系统的库目录下，将上面生成的usb_modeswitch可执行程序和usb_modeswitch.setup拷贝到文件系统/usr/sbin和/etc目录下。四、交叉编译3G卡片驱动在2.6.28内核源码中驱动/driver/usb/serial/ option.c中加入3G卡片的ID信息：#define HUAWEI_PRODUCT_E1750 0x1446Make menuconfig 选上编译这个文件的选项修改文件drivers/usb/storage/unusual_devs.h,去掉对移植网卡ID的屏蔽，关于此官方是这样说的：Kernel related issuesIn some newer kernels, certain device families (some Option, some Huawei, some ZTE as mentioned above) get a special treatment in the usb-storage code to enable switching right away. You would not need USB_ModeSwitch anymore for these specific dvices; on the other hand you have no choice of accessing the CD-ROM part of your device. Plus, there were cases when the special treatment brought no results and furthermore prevented USB_ModeSwitch to work properly afterwards (happened with ZTE devices, error -2). In case of trouble, look into unusual_devs.h in the drivers/usb/storage folder of your kernel source. If your default ID (vendor and product ID of the storage part) can be found there and you get errors when running USB_ModeSwitch, try first to blacklist usb-storage.If that helps, you should consider rebuilding your kernel with the entry in unusual_devs.h deactivated. The only thing that will happen is that usb-storage works in the default way afterwards.I found a tip in the Russian Gentoo wiki to do exactly what I just suggested for the ZTE MF626. 修改完内核后执行make uImage生成内核镜像文件五、利用usb_modeswitch进行模式转换移植完usb_modeswitch，libusb，更新内核后执行命令进行模式转换# ./usb_modeswitch c usb_modeswitch.conf执行后正常的话在/dev下生成了ttyUSB0、ttyUSB1、ttyUSB2等节点。执行lsusb命令就可以发现ID由0x1446变为0x1001.六、交叉编译pppd拨号工具，并编写拨号脚本1. 移植pppd拨号工具，并在内核里将相关的选项选上。a) 下载编译ppp-2.4.5解压b) 进入chat目录， 编译chat: make f Makefile.linux -host=arm-none-linux-gnueabi,生成chatc) 进入pppd目录， 编译pppd: make f Makefile.linux -host=arm-none-linux-gnueabi,生成pppd，可能会出现找不到pcap.h需要交叉编译libpcap后面有说明d) 将chat、pppd拷贝到/usr/sbin/目录e) 当服务器要求pppd给出用户身份认证信息的时候，如果协商采用PAP认证方式，pppd将到/etc/ppp/pap-secrets文件中取得用户口令；如果协商采用CHAP认证方式，则pppd将到/etc/ppp/chap-secrets文件中取得用户口令。因此需要对/etc/ppp/pap-secrets和/etc/ppp/chap-secrets做修改，修改PAP认证所需要的用户名密码，在文件/etc/ppp/pap-secrets中添加card * card *修改CHAP认证协议所需的用户名和口令，在文件/etc/ppp/ chap-secrets中添加card * card *下面介绍拨号脚本的编写：wcdma：nodetach#lock/dev/ttyUSB0#115200460800#user card#password card#crtscts#show-password#usepeerdnsnoauthnoipdefaultnovjnovjccompnoccpdefaultrouteipcp-accept-localipcp-accept-remoteconnect /usr/sbin/chat -s -v -f /etc/ppp/peers/chat-wcdma-connect #persist#disconnect /usr/sbin/chat -s -v -f /etc/ppp/peers/chat-wcdma-disconnectchat-wcdma-connect:ABORT NO CARRIERABORT ERRORABORT NO DIALTONEABORT BUSYABORT NO ANSWER /rATOK /rATZOK /rAT+CGDCONT=1,IP,3gnet,0,0OK-AT-OK ATDT*99#CONNECT /d/c chat-wcdma-disconnect:ABORT ERRORABORT NO DIALTONESAY /nSending break to the modem/n /K +ATHSAY /nGoodbay/n将wcdma、chat-wcdma-connect、chat-wcdma-disconnect三个文件拷贝到/home/filesys/etc/ppp/peers 目录下，在/etc/resolv.conf中添加DNS号Nameserver 51修改/etc/network/interfacds文件，设置网卡的工作模式如下：Auto eeth0 iface eth0 inet static address 2 network netmask broadcast 55 gateway 开始拨号root:/opt/3g# pppd call wcdma&拨号成功后会获得自动分配的IP地址Serial connection established.usb 1-1: pppd timed out on ep0outUsing interface ppp0Connect: ppp0 /dev/ttyUSB0PAP authentication succeededCould not determine remote IP address: defaulting to 4Cannot determine ethernet address for proxy ARPlocal IP address 0remote IP address 4ping 如能ping通，则说明移植成功。root:/opt/3g# ping PING (3) 56(84) bytes of data.64 bytes from 3: icmp_seq=1 ttl=54 time=367 ms64 bytes from 3: icmp_seq=2 ttl=54 time=320 ms64 bytes from 3: icmp_seq=3 ttl=54 time=300 ms64 bytes from 3: icmp_seq=4 ttl=54 time=310 ms64 bytes from 3: icmp_seq=5 ttl=54 time=330 ms交叉编译libpcap-0.9.5.tar.gz1. 声明环境变量：export PATH=/usr/local/arm/2.95.3/bin:$PATH2. 解压libpcap-0.9.5.tar.gz，cd进入目录，修改confiugre文件，把下面两段注释掉 #if test -z $with_pcap & test $cross_compiling = yes; then # echo $as_me:$LINENO: error: pcap type not determined when cross-compiling; use -with-pcap=. &5 #echo $as_me: error: pcap type not determined when cross-compiling; use -with-pcap=. &2; # (exit 1); exit 1; ; # f i . # if test $ac_cv_linux_vers = unknown ; then # echo $as_me:$LINENO: error: cannot determine linux version when cross-compiling &5 # echo $as_me: error: cannot determine linux version when cross-compiling &2; # (exit 1); exit 1; ; # fi3. 执行./configure -host=arm-linux，这样就会使用arm-linux-gcc进行configure，生成Makefile4. 修改Makefile的prefix项为prefix=/usr/local/arm/2.95.3/arm-linux，同时注意查看Makefile中的CC项，已经为arm-linux-gcc了，呵呵。5. 接下来make，make install，完成了libpcap的编译和安装，查看/usr/local/arm/2.95.3/arm-linux/include，该目录下增加了三个pcap的文件库编译 usbutils-0.90.tar.gz （包含lsusb工具）下载usbutils-0.90.tar.gz解压进入./configure CC=arm-none-linux-gnueabi-gcc -host=arm-none-linux-gnueabi LIBUSB_CFLAGS=/home/libusb-0.1.12/install/include LIBUSB_
