8192 在imx53 linux上移植
8192wifi驅動
1.編譯8192.ko
編譯過程是進入8192，執行
./make_drv
選1
添加一個新的CONFIG_PLATFORM_ARM_MX53=y，把其他的那個改成n
編輯Makefile
添加下面代碼
ifeq ($(CONFIG_PLATFORM_ARM_MX53), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WISTRON_PLATFORM
ARCH := arm
CROSS_COMPILE := /opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/arm-none-linux-gnueabi-
KVER := 2.6.35
KSRC ?= /home/vmuser/ltib_x7/ltib/rpm/BUILD/X7_kernel
endif
執行
make
會産生8192cu.ko
搞到闆子上
insmod 8192cu.ko
2. 啟動wlan0
ifconfig -a 會發現wlan0
ifconfig wlan0 192.168.2.1
ifconfig wlan0 up
3.設定8192為client
#wpa_supplicant 服務端程式，使用配置腳本wpa_supplicant.conf 自動連接配接到ap
#wpa_cli用于互動的用戶端程式，比如可以用于手動連接配接到某個ap
./wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf &
#自動擷取ip位址
udhcpc -i wlan0
#/etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
#ap_scan=1
network={
ssid="mywlan"
psk="1234567890"
proto=WPA2
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
priority=20
}
4.設定8192為ap：
#hostapd 服務端程式，使用腳本hostapd.conf自動配置資訊，配置檔案hostapd.conf
#hostapd_cli用于互動的用戶端程式,比如
#hostpd_cli all_sta列出所有的已連接配接的client
#iwlist wlan0 scan ; cat /proc/net/rtl819xC/wlan0/best_channel 檢視最好的channel
./hostapd ./hostapd.conf -B
#啟動dhcp伺服器：
#配置檔案位于/etc/dhcpd.conf
dhcpd wlan0

直接使用無線管理工具 wireless_tools ，也能實作8192與遠端 AP 的連結以及無線網絡的通信。
其中， iwconfig 用來配置無線網卡， iwlist 用來搜尋無線網絡。
ifconfig wlan0 192.168.2.2 netmask 255.255.254.0 up
iwlist wlan0 scanning
iwconfig wlan0 essid “mywlan”
iwconfig wlan0 key 1234567890
