ok..
how to download wireless tools . I don't understand lib,module...
I make only copy scan-wifi,start-wifi,wpa-supplicant
and

# scan-wifi                                                    
modprobe: chdir(/lib/modules): No such file or directory                   
    
modprobe: chdir(/lib/modules): No such file or directory                   
    
modprobe: chdir(/lib/modules): No such file or directory                   
    
modprobe: chdir(/lib/modules): No such file or directory                   
    
ifconfig: SIOCGIFFLAGS: No such device

I get this.
How do I solve this problem

I compiled wireless tool-29 as down
 ARCH=arm CC=arm-linux-gcc-4.3.2 make
 ARCH=arm CC=arm-linux-gcc-4.3.2 make install 

and iwconfig iwlist iwpriv iwspy iwgetid iwevent ifrename files copy in
/usr/sbin/  and 
libiw.so.29  iwlib.so files copy in /lib

and run iwconfig,iwlist I get eror 
[root@mini2440 /]# iwconfig                                                
       
/usr/sbin/iwconfig: line 2: syntax error: unexpected word (expecting ")")

What kernel and root filesystem are you using?

davef

Ah, you did check that you generated armv4t binaries?
