Linux Fedora14下利用DNW烧写文件

买了一套友善的板子 micro2440

由于win下面的DNW不是很好用

于是便装了FC14下面的dnw for linux ，很好用，也很方便

 

1 下载 DNW for linux

 友善的BBS上面可下载

 我也共享了一个免费下载: http://download.csdn.net/source/3076530 ,

 

2 安装

       2.1 解压

$tar xzvf dnw_linux.tar.gz
dnw_linux/
dnw_linux/secbulk/
dnw_linux/secbulk/Makefile
dnw_linux/secbulk/secbulk.c
dnw_linux/dnw/
dnw_linux/dnw/dnw.c

其中secbulk.c是linux的USB驱动, dnw.c 是写入工具的源代码

2.2 驱动模块的编译与加载
$cd secbulk
$make -C /lib/modules/`uname -r`/build M=`pwd` modules
如果编译出错，差东西，可能是没有装内核的东西

用 yum 等下载安装kernel-devel kernel-headers
编译成功后在当前目录下可以看到secbulk.ko

[ty@tiany dnw]$ ll

total 352
-rw-rw-r-- 1 ty ty 42 Oct 25 2008 Makefile
-rw-r--r-- 1 root root 55 Mar 9 15:46 modules.order
-rw-r--r-- 1 root root 0 Mar 9 15:46 Module.symvers
-rw-rw-r-- 1 ty ty 4530 Jan 6 2009 secbulk.c
-rw-r--r-- 1 root root 164268 Mar 9 15:46 secbulk.ko
-rw-r--r-- 1 root root 497 Mar 9 15:46 secbulk.mod.c
-rw-rw-r-- 1 root root 45328 Mar 9 15:46 secbulk.mod.o
-rw-r--r-- 1 root root 120112 Mar 9 15:46 secbulk.o

insmod 加载模块,注意 root 权限
$sudo insmod secbulk.ko

成功加载后用 dmesg 命令查看日志， 通过grep过滤
[ty@tiany dnw]$ dmesg | grep secbulk
[ 1882.227272] secbulk:secbulk loaded
[ 1882.227305] usbcore: registered new interface driver secbulk

2.3 编译 dnw 工具
$cd dnw
$gcc -o dnw dnw.c
编译成功后生成可执行dnw

3 使用

    我是fc14系统，内核版本为

     [ty@tiany dnw]$ uname -a
    Linux tiany.lab2202 2.6.35.6-45.fc14.i686 #1 SMP Mon Oct 18 23:56:17 UTC 2010 i686 i686 i386 GNU/Linux

 

      连上设备，用dmesg可以看到usb链接的信息

[ 1152.956029] usb 7-2: new full speed USB device using uhci_hcd and address 4
[ 1153.115268] usb 7-2: New USB device found, idVendor=5345, idProduct=1234

[ 2061.900170] secbulk:secbulk probing...
[ 2061.900174] secbulk:bulk out endpoint found!

 

       正确链接后就可以利用DNW工具下载

[ty@tiany dnw]$ sudo ./dnw 2440test_N35.bin
[sudo] password for ty:
file name : 2440test_N35.bin
file size : 4033684 bytes
Writing data...
100% 4033694 bytes OK

 

OK，安装测试完毕，使用很方便

 

 

笔记

发现一个奇怪的问题，我用的Mirco2440SDK这块板子，

更换核心板后，dnw老是用不起，不知道为什么

secbulk.ko

可以加载成功，但是连接上USB后 dmesg查看消息 输出以下错误

 611.547551] usbcore: registered new interface driver secbulk
[  637.539046] usb 7-1: new full speed USB device using uhci_hcd and address 10

[  639.573180] hub 7-0:1.0: unable to enumerate USB device on port 1

 

不知道为什么

然后我换回之前调试的核心板

又可以使用了

真实奇怪
