			主機(jī)平臺(tái)：Gentoo Linux 11.2 with linux kernel 3.0.6
        硬件平臺(tái)：FL2440（S3C2440）with linux kernel 2.6.35

        1、首先下載DNW for linuxhttp://download.csdn.net/source/1011140
        2、解壓文件
        、
        3、編譯主機(jī)的USB驅(qū)動(dòng)
        1. make-C/lib/modules/`uname-r`/buildM=`pwd`modules

        然后insmod安裝驅(qū)動(dòng)并dmesg查看如下
        4、修改dnw.c文件并編譯
        由于FL2440燒寫內(nèi)核需要設(shè)置初始地址為0x30800000，修改后文件如下
