解释: 这一行对配置网络,连通Target Server及下载调试程序非常重要


DEFAULT_BOOT_LINE 的原意是为没有NVRAM的target设计的,这样用户就不需要在每次系统启动是手工输入这些参数了.


系统启动网络时xxxEndLoad()会解释这一行并按这一行的定义进行加载.


Emac(0,0) : 启动设备,可是是软盘,硬盘,PCMCIA卡等 其他的设备名称如:


fd为软盘,(0,0)表示第一个软驱,3.5寸盘.
dc则表示从DEC 21x4x 芯片启动,即系统有NVRAM存在,这种方式现在已不采用.
elpci表示启动设备为3COM EtherLink XL PCI网卡.
fei:Intel 82559 EtherExpress网卡.
ene: NE2000网卡
ELT: 3COM以太网卡
EEX: Intel网卡
ata: ATA/IDE 硬盘 ............


405GP: 主机名
vXworks 从主机加载的VxWorks文件
h=172.16.1.159?主机的IP地址?


e=172.16.254.52 目标机的IP地址,若网络启动Target Server时,这个IP必须和主机上Target Server配置的Target IP地址一致,且设置Back End选项为wdbrpc
u=xxx?用户名,pw=xxx?密码: 若通过网络加载调试时,主机的Ftp服务器和目标机的用户名和密码必须相同
tn=vxTarget 目标机名称

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。



1.在C:\Tornado\target\config\pcPentium目录下修改BSP文件config.h。


#elif (CPU_VARIANT == PENTIUM)
#define DEFAULT_BOOT_LINE?
"elt(0,0)HOST:c:\\Tornado\\target\\config\\pcPentium\\vxWorks?
h=90.0.0.3 e=90.0.0.50 u=target pw=target tn=target"

#define INCLUDE_ELT //3Com网卡
#define INCLUDE_END //END驱动




2.打开Tornado选择新建一个bootable vxworks image,选择建 A BSP,选择
pcPentium,建完后编译就可以在相应的目录下生成vxworks的映像文件。

3.制作bootrom;选择Build Boot Rom,选择pcPentium,再选择bootrom_uncmp,
生成 bootrom_uncmp。拷贝 bootrom_uncmp到host\x86-win32\bin下,插入空白
盘到软区,在dos界面进入目录host\x86-win32\bin下,用命令"mkboot a:?
bootrom_uncmp "生成引导盘?

4. 在Start > Programs > Tornado2 > FTP Server,点开Security下的
user/rights菜单,新建用户User Name:target,Password:target,Home?
Directory为VxWorks映像所在目录如 C:\Tornado\target\config\pcPentium\。
注意这些配置要和config.h中的一致。

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
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
,自动),手工方式可对FTP用户,口令,IP等参数进行修改。
通常是等待7秒后系统autoboot。


屏幕显示:


Attached TCP/IP interface to elt0.
Attaching network interface lo0... done. //TCP/IP网络连接成功

Loading... 602128 //通过ftp下载VxWorks映像
Starting at 0x01080000 //下载成功,从RAM_LOW_ADRS 0x01080000
开始执行VxWorks系统

Attached TCP/IP interface to elt unit 0
Attaching interface lo0...done //TCP/IP网络连接成功
(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。)

CPU: xxxx --- Intel x82?

至此目标机系统启动完成。


6.配置Target Server下载应用程序.


打开Tornado,在Tools菜单下选择Target Sever再选择configure进行配置(Tools?
> Target Server > Configure > New)给出Target Server名字描述如net00.在
(Target Server Properties > Back End)选择WdbRpc. Target Name/IP Address?
框内输入Target的IP: 90.0.0.50.?
Core File and Symbols选项(Target Server Properties > Core File and?
Symbols): C:\Tornado\target\config\pcPentium\vxWorks等等。
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
面下选择已启动的Target Sever就可以下载 *.o或*.out程序。
