wifi驱动移植

目标板：Hi3518

内核版本：linux3.0.8

 

1.修改makefile

#PLATFORM = PC     //注释掉
PLATFORM = HI3518     //支持平台

ifeq ($(PLATFORM),HI3518)
LINUX_SRC = /root/hi3518/linux-3.0.y     //内核路径
CROSS_COMPILE = /opt/hisi-linux-nptl/arm-hisiv100-linux/target/bin/arm-hisiv100nptl-linux- //工具链路径
endif

2.进入RT3070/include/rtmp_def.h

    #define INF_MAIN_DEV_NAME     "wlan"
    #define INF_MBSSID_DEV_NAME "wlan"

3.修改os/linux/config.mk使其支持wpa_suplicant(将‘n'变成'y')

# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y
# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

4.在编译驱动前必须先编译image

问题一：

/root/hi3518/RT3070/os/linux/../../os/linux/sta_ioctl.c:: error: unknown field 'private' specified in initializer
/root/hi3518/RT3070/os/linux/../../os/linux/sta_ioctl.c:: warning: initialization from incompatible pointer type

]: *** [_module_/root/hi3518/RT3070/os/linux] 错误
]:正在离开目录 `/root/hi3518/linux-3.0.y'

问题原因：是因为在配置Makefile时，指定的内核在配置时不支持802.11的无线设备驱动。

解决办法：重新配置编译指定的Linux Kernel，将Device Drivers

   ==>Network deivce support
       ==>Wireless LAN
        ==><*> USB ZD1201 based Wireless device support，编译即可

问题二：

rt3070sta: module has no symbols (stripped?)
insmod: can't insert 'rt3070sta.ko': invalid module format

解决办法：不能对目标文件进行裁剪

rtusb init rt2870 --->
usbcore: registered new interface driver rt2870

如果出现以下报错，说明内核源码错了

rt5370sta: version magic '2.6.32.59 mod_unload ARMv4 ' should be '2.6.32.2-Frie'
insmod: cannot insert 'rt5370sta.ko': invalid module format

插入网卡，这个时候ifconfig是看不到网卡的，要启用网卡，用以下命令：

ifconfig ra0 up
