关于ARM上移植无线网卡的问题
如题，使用compat-wireless-2.6.39-1开发包，在交叉编译环境下编译生成的.ko文件如下：ema@ubuntu:~/work/skw17/compat-wireless-2.6.39-1$ find -name *ko
./drivers/net/wireless/ath/ath.ko
./drivers/net/wireless/ath/ath9k/ath9k_hw.ko
./drivers/net/wireless/ath/ath9k/ath9k_htc.ko
./drivers/net/wireless/ath/ath9k/ath9k_common.ko
./net/wireless/cfg80211.ko
./net/mac80211/mac80211.ko
./compat/compat.ko
./compat/kfifo.ko
./compat/compat_firmware_class.ko
在内核中的配置是：
CONFIG_NET_SCHED=y
CONFIG_CFG80211=m
CONFIG_MAC80211=m
CONFIG_RFKILL=m
CONFIG_WLAN=y
无 CONFIG_WLAN_80211项
在开发板中加载模块如下：
root@beagleboard:/home/ema/skw17# insmod compat.ko

其中的rfkill.ko不是无线模块开发包中生成的，是内核中生成的。
我在开发板的/lib下新建一个firmware文件，然后在其中放了ar9271.fw文件
root@beagleboard:~# ll /lib/firmware/
drwxr-xr-x 2 root root 304 Feb 16 00:10 ./
drwxr-xr-x 5 root root 3352 Feb 162011 ../
-rwxr-xr-x 1 root root 51312 Feb 15 23:58 ar9271.fw*
-rwxr-xr-x 1 root root 51272 Feb 16 00:02 htc_9271.fw*
可是为什么总是提示无法找到ar9271.ko文件呢？
