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

  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:dwnn");
  18. return1;
  19. }
  21. intfd=open(argv[1],O_RDONLY);
  22. if(-1==fd)
  23. {
  24. printf("Cannotopenfile-%sn",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:%sn",argv[1]);
  48. printf("filesize:%dbytesn",file_stat.st_size);
  50. intfd_dev=open(dev,O_WRONLY);
  51. if(-1==fd_dev)
  52. {
  53. printf("Cannotopen%sn",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("OKn");
  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. }

最后燒寫內(nèi)核
