//----------------------------------------------------
//AUTHOR: lanyang123456

//----------------------------------------------------
硬件：ARM 开发板 OK6410
系统：linux 2.6.28内核
无线USB网卡 腾达 型号：W311M
芯片类型rt5370
第一步：下载驱动
驱动下载地址 腾达官网下载
http://www.tenda.com.cn/tendacn/Product/show.aspx?productid=172&type=2
或者到无线芯片组解决方案开发商 Ralink Technology公司官网下载
http://www.ralinktech.com/en/04_support/support.php?sn=501
第二步：
解压 tar –jvxf 2011_0225_RT5370_RT5372_Linux_STA_V2.5.0.1_DPO.tar.bz2
修改驱动源码根目录下的Makefile
PLATFORM=SMDK
LINUX_SRC=/usr/local/arm/linux-2.6.28(内核源码目录)
CROSS_COMPILE=/usr/local/arm/4.2.2-eabi/usr/bin/arm-linux-
第三步：
编译驱动
#make
在os/linux 目录生成最后的ko文件rt5370sta.ko
第四步：
将rt5370驱动源码目录下的RT2870STA.dat拷贝到/etc/Wireless/RT2870STA/目录下（首先要创建/etc/Wireless/RT2870STA）
第五步：
加载驱动
将rt5370sta.ko拷贝到开发板
#insmod rt5370sta.ko
[root@OK6410 linux]# insmod rt5370sta.ko
rtusb init rt2870 --->
=== pAd = c884c000, size = 512016 ===
<-- RTMPAllocTxRxRingMemory, Status=0
<-- RTMPAllocAdapterBlock, Status=0
usbcore: registered new interface driver rt2870
第六步：
激活无线网卡
插入无线USB网卡
网卡接口为ra0
激活ra0
#ifconfig ra0 up
[root@OK6410 linux]# ifconfig ra0 up

1. Phy Mode = 5
2. Phy Mode = 5

MacValue1=2
MacValue2=0
MCS Set = ff 00 00 00 01
<==== rt28xx_init, Status=0
0x1300 = 00064300
第七步：无线网络配置
配置无线网络ESSID
[root@OK6410 linux]# iwconfig ra0 essid DLUT
查看配置
[root@FORLINX6410]# iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"DLUT"
Mode:Managed Frequency:2.412 GHz Access Point: 11:22:33:44:55:66
Bit Rate=21.7 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
Link Quality=43/70 Signal level=-67 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:2 Invalid misc:0 Missed beacon:0
配置自动获取IP
在ARM板linux系统下，使用dhclient命令会提示无法找到该命令，首先需要进行dhcp移植。
移植dhcp 详见http://blog.csdn.net/lanyang123456/article/details/7361781 。
移植成功后
[root@FORLINX6410]# dhclient wlan0

查看配置
[root@FORLINX6410]# ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:ff

RX bytes:6920184 (6.5 MiB) TX bytes:185103 (180.7 KiB)
配置结束，打开浏览器，输入无线账号、密码，现在可以上网了。
有一个问题：#dmesg查看内核缓冲区，发现一直输出，不知何故。
GetDesiredTssiAndCurrentTssi: BBP TSSI INFO is not ready. (
BbpR47 = 0x4)
AsicAdjustTxPower: Incorrect desired TSSI or current TSSI

-------------------------------------------------------------------------------------------
另外，Linux 内核3.0.1 自带RT53** RT28**等系统芯片的驱动drivers/net/wireless/rt2x00/，不需要再去下载驱动，并且不会出现上面的问题。
插入USB无线网卡后，系统识别，输出

usb 1-1: not running at top speed; connect to a high speed hub
usb 1-1: New USB device found, idVendor=148f, idProduct=5370

phy1 -> rt2x00_set_chip: Info - Chipset detected - rt: 5390, rf: 5370, rev: 0502
.
接着，将驱动源码目录下common/rt2870.bin文件拷贝到开发板/lib/firmware/目录下
激活无线接口
[root@FORLINX6410]# ifconfig wlan0 up
phy1 -> rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin'.
phy1 -> rt2x00lib_request_firmware: Info - Firmware detected - version: 0.236.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 0 - CWmin: 3, CWmax: 4, Ai
fs: 2, TXop: 102.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 1 - CWmin: 4, CWmax: 5, Ai
fs: 2, TXop: 188.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 2 - CWmin: 5, CWmax: 10, A
ifs: 3, TXop: 0.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 3 - CWmin: 5, CWmax: 10, A
ifs: 7, TXop: 0.
[root@FORLINX6410]# phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 2 - CW
min: 4, CWmax: 10, Aifs: 3, TXop: 0.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 3 - CWmin: 4, CWmax: 10, A
ifs: 7, TXop: 0.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 1 - CWmin: 3, CWmax: 4, Ai
fs: 2, TXop: 94.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 0 - CWmin: 2, CWmax: 3, Ai
fs: 2, TXop: 47.
然后配置无线网络ESSID ,配置自动获取IP后，就可以上网了。
