                          how to boot target by serial connect and debug

modify at the config.h file end:
/* add by frank */
#undef WDB_COMM_TYPE
#define WDB_COMM_TYPE  WDB_COMM_SERIAL

#undef CONSOLE_TTY
#define CONSOLE_TTY         0  /* console口,根据自己的修改,有2个串口的可改成1 */

#undef WDB_TTY_CHANNEL
#define WDB_TTY_CHANNEL     0

#undef WDB_TTY_BAUD
#define WDB_TTY_BAUD  38400 /* default baud rate is 9600*/

#define INCLUDE_TSFS_BOOT

/*end by frank */

(方便调试，可关掉启动时的重定向)
in the tornado\target\config\all\bootconfig.c, undefine the tsfs_boot_vio_console by :
找到：
#ifdef  INCLUDE_TSFS_BOOT  /* boot via Target Server File System */

#if ((WDB_COMM_TYPE == WDB_COMM_SERIAL) && \
 (CONSOLE_TTY == NONE || CONSOLE_TTY == WDB_TTY_CHANNEL))
#define INCLUDE_TSFS_BOOT_VIO_CONSOLE /* needed for Target Server Console */
#endif
改为：
#ifdef  INCLUDE_TSFS_BOOT  /* boot via Target Server File System */

#if ((WDB_COMM_TYPE == WDB_COMM_SERIAL) && \
 (CONSOLE_TTY == NONE || CONSOLE_TTY == WDB_TTY_CHANNEL))
#undef INCLUDE_TSFS_BOOT_VIO_CONSOLE /* needed for Target Server Console */
#endif

please note the value of wdb_tty_baud .
To avoid some error of networking, could undefine the INCLUDE_END.

重编译生成bootrom和vxworks.

当bootrom启动了之后，要在host边开tsfs服务。具体设置如下：
1.选择tool->target server->configure...,在Back End项中，选择wdbserial,选择对应的com口及波特率。
2.在Core File and Symbols项中，File栏先不选对应的Vxworks文件。
3.在Target Server File System项中，选中Enable File System,Root中选择对应的Vxworks所在目录。
4.根据需要对Console and Redirection项中的重定位进行选择。(不选)
5.最后，点击Launch,启动target server的tsfs.
这样就开始通过串口下载vxworks映像。

下载完后，如要通过串口调试，先关掉原下载vxworks时的target server, target server配置中在Core File and Symbols项中，File栏选对应的Vxworks文件,点击launch启动target server即可。
