ARM-Linux驱动移植--Linux下烧写工具DNW和USB驱动安装
主机平台：Gentoo Linux 11.2 with linux kernel 3.0.6
硬件平台：FL2440（S3C2440）with linux kernel 2.6.35

1、首先下载DNW for linux http://download.csdn.net/source/1011140
2、解压文件
3、编译主机的USB驱动
view plaincopyprint?01.make -C /lib/modules/`uname -r`/build M=`pwd` modules 然后insmod安装驱动并dmesg查看如下
4、修改dnw.c文件并编译
由于FL2440烧写内核需要设置初始地址为0x30800000，修改后文件如下
view plaincopyprint?01.#include <stdio.h>
02.#include <stdlib.h>
03.#include <malloc.h>
04.#include <sys/types.h>
05.#include <sys/stat.h>
06.#include <unistd.h>
07.#include <fcntl.h>

67. size_t remain_size = file_stat.st_size+10;
68.//size_t block_size = remain_size / 100;
69. size_t block_size = 512;
70. size_t writed = 0;
71. while(remain_size>0)
72. {
73. size_t to_write = remain_size > block_size ? block_size:remain_size;
74. if( to_write != write(fd_dev, file_buffer+writed, to_write))
75. {
76. printf("failed!\n");
77. return 1;
78. }
79. remain_size -= to_write;
80. writed += to_write;
81. printf("\r%d%\t %d bytes ", writed*100/(file_stat.st_size+10), writed);
82. fflush(stdout);
83.
84. }
85.
86. printf("OK\n");
87. return 0;
88.
89.error:
90. if(-1!=fd_dev) close(fd_dev);
91. if(fd != -1) close(fd);
92. if( NULL!=file_buffer )
93. free(file_buffer);
94. return -1;
95.}最后烧写内核
