    The warning does not matter.

    You have to do some wireless tools,

    iwlist eth0 scanning # find available APs

    iwconfig eth0 ap auto essid "Your SSID" # connect to an AP

    If your AP is protected, you need to add key to iwconfig, see `man iwconfig`

    Please run "make" and "make linux image" .

    The "make" will strip the modules, so the compressed image should be around 1.5M .

    Something wrong in your romfs.

    cd ~/uClinux-dist

    rm -rf romfs

    make romfs

    make

    cd ~/zd1211

    make # compile modules and copy to romfs, the make file do the copy, don&#39;t copy it by hand

    cd ~/uClinux-dist

    make # depmod and strip the modules (ie, remove debug symbols and reduce the size)

    make linux image # to update initramfs
