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 linuxhttp://download.csdn.net/source/1011140

2、解压文件

、

3、编译主机的USB驱动

1. make-C/lib/modules/`uname-r`/buildM=`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

1. #include
2. #include
3. #include
4. #include
5. #include
6. #include
7. #include
9. constchar*dev="/dev/secbulk0";
12. intmain(intargc,char*argv[])
13. {
14. unsignedchar*file_buffer=NULL;
15. if(2!=argc)
16. {
17. printf("Usage:dwn\n");
18. return1;
19. }
21. intfd=open(argv[1],O_RDONLY);
22. if(-1==fd)
23. {
24. printf("Cannotopenfile-%s\n",argv[1]);
25. return1;
26. }
28. structstatfile_stat;
29. if(-1==fstat(fd,&file_stat))
30. {
31. printf("Getfilesizefiled!\n");
32. return1;
33. }
35. file_buffer=(char*)malloc(file_stat.st_size+10);
36. if(NULL==file_buffer)
37. {
38. printf("mallocfailed!\n");
39. gotoerror;
40. }
41. if(file_stat.st_size!=read(fd,file_buffer+8,file_stat.st_size))
42. {
43. printf("Readfilefailed!\n");
44. gotoerror;
45. }
47. printf("filename:%s\n",argv[1]);
48. printf("filesize:%dbytes\n",file_stat.st_size);
50. intfd_dev=open(dev,O_WRONLY);
51. if(-1==fd_dev)
52. {
53. printf("Cannotopen%s\n",dev);
54. gotoerror;
55. }
57. *((unsignedlong*)file_buffer)=0x30800000;//loadaddress
58. *((unsignedlong*)file_buffer+1)=file_stat.st_size+10;//filesize
59. unsignedshortsum=0;
60. inti;
61. for(i=8;i
62. {
63. sum+=file_buffer[i];
64. }
66. printf("Writingdata...\n");
67. size_tremain_size=file_stat.st_size+10;
68. //size_tblock_size=remain_size/100;
69. size_tblock_size=512;
70. size_twrited=0;
71. while(remain_size>0)
72. {
73. size_tto_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. return1;
78. }
79. remain_size-=to_write;
80. writed+=to_write;
81. printf("\r%d%\t%dbytes",writed*100/(file_stat.st_size+10),writed);
82. fflush(stdout);
84. }
86. printf("OK\n");
87. return0;
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
