%A 　 Tornado for x86下BSP的生成,下载和Target Server的配置实例，Pentium主机，3Com网卡，软盘引导，ftp下载VxWorks映像。
%A
%A      1.在C:\Tornado\target\config\pcPentium目录下修改BSP文件config.h。
%A
%A
%A #elif (CPU_VARIANT == PENTIUM)
%A #define DEFAULT_BOOT_LINE
%A "elt(0,0)HOST:c:\\Tornado\\target\\config\\pcPentium\\vxWorks
%A h=90.0.0.3 e=90.0.0.50 u=target pw=target tn=target"
%A
%A #define INCLUDE_ELT //3Com网卡
%A #define INCLUDE_END //END驱动
%A
%A
%A 2.打开Tornado选择新建一个bootable vxworks image，选择建 A BSP，选择
%A   pcPentium，建完后编译就可以在相应的目录下生成vxworks的映像文件。
%A
%A 3.制作bootrom；选择Build Boot Rom，选择pcPentium,再选择bootrom_uncmp，
%A   生成 bootrom_uncmp。拷贝 bootrom_uncmp到host\x86-win32\bin下，插入空白
%A   盘到软区，在dos界面进入目录host\x86-win32\bin下，用命令"mkboot a:
%A   bootrom_uncmp "生成引导盘
%A
%A 4. 在Start > Programs > Tornado2 > FTP Server，点开Security下的
%A   user/rights菜单，新建用户User Name:target，Password:target，Home
%A   Directory为VxWorks映像所在目录如 C:\Tornado\target\config\pcPentium\。
%A   注意这些配置要和config.h中的一致。
%A
%A 5.将bootrom的启动盘插入目标机的软驱，启动目标机，系统从软驱启动，随后登
%A   陆FTP，从主机下载vxworks文件，目标机提示7秒内按任意键选择Boot方式（手工
%A   ，自动），手工方式可对FTP用户，口令，IP等参数进行修改。
%A   通常是等待7秒后系统autoboot。
%A   
%A
%A 屏幕显示：
%A
%A Attached TCP/IP interface to elt0.
%A Attaching network interface lo0... done. //TCP/IP网络连接成功
%A
%A Loading... 602128 //通过ftp下载VxWorks映像
%A Starting at 0x01080000 //下载成功，从RAM_LOW_ADRS 0x01080000
%A 开始执行VxWorks系统
%A
%A Attached TCP/IP interface to elt unit 0
%A Attaching interface lo0...done //TCP/IP网络连接成功
%A (注意这里网络初始化成功和上边的不同，上边是Bootrom映像网络初始化来下载VxWorks,这里VxWorks系统初始化网络。)

%A 至此目标机系统启动完成。
%A
%A
%A 6.配置Target Server下载应用程序.
%A
%A 打开Tornado，在Tools菜单下选择Target Sever再选择configure进行配置(Tools
%A > Target Server > Configure > New)给出Target Server名字描述如net00.在
%A (Target Server Properties > Back End)选择WdbRpc. Target Name/IP Address
%A 框内输入Target的IP: 90.0.0.50.
%A Core File and Symbols选项(Target Server Properties > Core File and
%A Symbols)： C:\Tornado\target\config\pcPentium\vxWorks等等。
%A 配置的内容根据系统的具体情况定。点击Launch启动Target Sever，随后在主界
%A 面下选择已启动的Target Sever就可以下载 *.o或*.out程序。
