            ARM-Linux驅(qū)動(dòng)移植--Linux下燒寫工具DNW和USB驅(qū)動(dòng)安裝

            作者: 時(shí)間:2016-11-20 來(lái)源:網(wǎng)絡(luò) 收藏
            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

            最后燒寫內(nèi)核
