S3C2440实现wifi、3G上网和迷你无线路由的制作(一)
S3C2440实现wifi、3G上网和迷你无线路由的制作
fulinux 凌云实验室
本文将通过ARM、linux平台，借助RT2070/RT3070芯片的无线模块（或使用RT2070/RT3070芯片的USB无线上网卡）、3G无线上网卡，实现无线上网、通过ADSL和3G的迷你无线路由器的制作。
wifi上网
首先是利用s3c2440开发板和RT2070/RT3070芯片的无线模块实现无线上网的功能，即让无线模块工作在STA模式，所谓的STA在WLAN中一般为客户端，可以是装有无线网卡的计算机，也可以是有WiFi模块的智能手机。STA可以是移动的，也可以是固定的，是无线局域网的最基本组成单元。
这里假定已经成功移植了linux-3.0内核和可读写的文件系统，例如ubifs、yaffs和jffs2文件系统，这里使用jffs2。下图是已经运行好的系统在secure CRT上的显示的结果：
~ >: ls
apps data home lib media proc stat usr
backup dev info linuxrc mnt root sys var
bin etc init logs opt sbin tmp
~ >:
这里使用一个集成RT2070芯片的USB无线网卡（或其他无线模块，注明一点就是3070和2070的模块是完全兼容的，下面我们只以RT2070模块作介绍），是下面是要用到的实物图：
（上图中的一些次要部件没有列出来，需要的部分会提到）
先测试USB无线模块是否正常，我把它插在电脑上并且连接在普通无线路由器上，显示如下所示，则说明正常。
之后拔出，因为我的电脑用有线。
内核配置
从Linux-3.0开始，RT2070/3070的STA驱动已经作为正式版本加入了Linux内核源码中了（从Linux-2.6.32开始以实验版本加入Linux内核中）。本篇文章主要介绍如何在内核中编译支持RT2070的STA模式驱动，并连接到我的无线路由器上去。
1， 配置Linux-3.0内核支持RT2070，我们以Build-in的方式将RT2070的驱动集成到内核里去，一下是一些需要的选项，其他配置可以自己试试：
[*] Networking support --->
-*- Wireless --->
<*> cfg80211 - wireless configuration API
[ ] nl80211 testmode command
[ ] enable developer warnings
[ ] cfg80211 regulatory debugging
[*] enable powersave by default
[ ] use statically compiled regulatory rules database
[ ] cfg80211 wireless extensions compatibility
<*> Common routines for IEEE802.11 drivers
[ ] lib80211 debugging messages
<*> Generic IEEE 802.11 Networking Stack (mac80211)
[ ] PID controller based rate control algorithm
[*] Minstrel
[*] Minstrel 802.11n support

[ ] Select mac80211 debugging features --->

[ ] Maintain a devtmpfs filesystem to mount at /dev
[ ] Select only drivers that don't need compile-time external firmware
[ ] Prevent firmware from being built

<*> Ralink driver support --->

< > Ralink rt2500 (USB) support
< > Ralink rt2501/rt73 (USB) support
<*> Ralink rt27xx/rt28xx/rt30xx (USB) support
[ ] rt2800usb - Include support for rt33xx devices
[ ] rt2800usb - Include support for rt35xx devices (EXPERIMENTAL)
[ ] rt2800usb - Include support for rt53xx devices (EXPERIMENTAL)
[ ] rt2800usb - Include support for unknown (USB) devices
[*] Ralink debug output
注明：
a、cfg80211：
cfg80211 is the Linux 802.11 configuration API. cfg80211 replaces Wireless-Extensions. nl80211 is used to configure a cfg80211 device and is used for kernel <–> userspace communication. Wireless extensions is now in maintenance mode, no new features will be added to it, we'll only fix bugs for it. cfg80211 is now feature-par complete with wireless-extensions, it actually has a lot more features that are simply not available and will never be available through wireless extensions. When implementing a cfg80211 driver wireless extensions support is still provided automatically for you through cfg80211 through CONFIG_CFG80211_WEXT. Distributions no longer needing wireless extensions can remove this and are encouraged to do so. cfg80211 also provides full regulatory support, this is done through wireless-regdb and the usage of CRDA.
All new Linux wireless drivers should be written targeting either cfg80211 for fullmac devices or mac80211 for softmac devices.
（摘自：http://wireless.kernel.org/en/developers/Documentation/cfg80211）
b、Minstrel：
minstrel is a mac80211 rate control algorithm ported over from MadWifi which supports multiple rate retries and claimed to be one of the best, if not the best, rate control algorithm.
（摘自：http://wireless.kernel.org/en/developers/Documentation/mac80211/RateControl/minstrel/）
c、hotplug
这里是支持热插拔。
d、Firmware
固件的目的是初始化，() External firmware blobs to build into the kernel binary这一选项可以加入固件路径。
e、[*] Ralink debug output
这个选项选了后容易出现下面的警告。
cfg80211: Calling CRDA to update world regulatory domain
2、插入RT2070无线网卡并加载新内核启动
………..

使用lsusb命令查看：
~ >: lsusb
Bus 001 Device 001: ID 1d6b:0001
Bus 001 Device 002: ID 05e3:0606
Bus 001 Device 003: ID 148f:2070
~ >:
如果是热插拔的话会，在插入的那一刻，串口会打印如下信息：
~ >: usb 1-1.1: new full speed USB device number 3 using s3c2410-ohci
usb 1-1.1: New USB device found, idVendor=148f, idProduct=
usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.1: Product: 802.11 g WLAN
usb 1-1.1: Manufacturer: Ralink
usb 1-1.1: SerialNumber: 1.0
ifconfig是查看网卡的信息。
ifconfig [Interface]
Interface是可选项，如果不加此项，则显示系统中所有网卡的信息。如果添加此选项则显示所指定的网卡信息，例如：
~ >: ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr C8:3A:35:C6:A2:B5
inet addr:192.168.5.1 Bcast:192.168.5.255 Mask:255.255.255.0
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
我们可以看到
第一行：连接类型：Ethernet（以太网）HWaddr（硬件mac地址）
第二行：网卡的IP地址、子网、掩码
第三行：MULTICAST（支持组播）MTU:1500（最大传输单元）：1500字节
第四、五行：接收、发送数据包情况统计
第七行：接收、发送数据字节数统计信息。
~ >: ifconfig wlan0 up
phy0 -> rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin'.
phy0 -> rt2x00lib_request_firmware: Error - Failed to request Firmware.
ifconfig: SIOCSIFFLAGS: No such file or directory
这时我们在使用RT2070的驱动时发现，RT2070的驱动还需要rt2870.bin这个系统固件(firmware)。
1， Linux内核官方站点下载rt2870.bin这个系统固件
I. PC上下载rt2870.bin这个系统固件：
[guowenxue@centos6 ~]$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
[guowenxue@centos6 ~]$ ls -l linux-firmware/rt2870.bin
-rw-rw-r-- 1 guowenxue guowenxue 8192 Dec 23 09:37 linux-firmware/rt2870.bin
II. 在AT91SAM9260开发板上将rt2870.bin下载到/lib/firmware路径下，这时能重启网卡:
/lib >: mkdir -p /lib/firmware
/lib >: cd firmware/
/lib/firmware >: tget rt2870.bin
rt2870.bin 100% |*******************************| 8192 0:00:00 ETA
/lib/firmware >: ls
rt2870.bin
iwconfig命令来自下面交叉编译的wireless_tools程序
~ >: iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off

~ >: ifconfig wlan0 up
phy1 -> rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin'.
phy1 -> rt2x00lib_request_firmware: Info - Firmware detected - version: 0.29.

phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 3 - CWmin: 5, CWmax: 10, Aifs: 7, TXop: 0.
2， 下载/交叉编译wireless_tools的shell脚本，这些工具包括iwconfig, iwlist, iwpriv等：

[guowenxue@centos6 wpa_supplicant]$ ls wpa_supplicant-0.7.3/wpa_supplicant/
*** wpa_supplicant *** wpa_cli *** wpa_passphrase
5， 安装上面交叉编译出来的一些二进制可执行文件到ARM开发板上：
~ >: ls /apps/tools/
iwlist wpa_passphrase iwpriv
wpa_supplicant iwconfig
使用wpa_passphrase创建wpa_supplicant的配置文件，使用加密后的密码，不用明文。当然使用明文密码也可以连接到无线路由器：
~ >: wpa_passphrase Router_Kernel password >> wpa_supplicant.conf
~ >: cat wpa_supplicant.conf
network={
ssid="Router_Kernel"
#psk="password"
psk=81a8c46543f339bbcd0381b4d7a13673d4e02f67108d978fb545435a15d95ea5
}
修改后的配置文件如下：
~ >: cat /apps/etc/wireless/wpa_supplicant.conf
# WPA-PSK/TKIP
# wpa_supplicant -Dwext -iwlan0 -c/apps/etc/wireless/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="Router_Kernel"
key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP
#psk="password" 这里使用明文密码也可以
