Here's how to run VxSim, a target server, and the Tornado shell from the command line in Windows. I am using Tornado 2.2.1 and Windows XP.

1. Open a "cmd.exe" window.
2. Enter the following commands as shown in my session:
   

   C:\>cd c:\Tornado2.2\target\config\simpc
   
   C:\Tornado2.2\target\config\simpc>vxworks
   
   C:\Tornado2.2\target\config\simpc>cd c:\tornado2.2\host\x86-win32\bin
   
   C:\Tornado2.2\host\x86-win32\bin>tgtsvr -V -B wdbpipe -R c:/temp -RW -c c:\Torna
   do2.2\target\config\simpc\vxWorks.exe vxsim

3. The target server icon should now show in your system tray. If you double-click on it, you should see:
   

   tgtsvr (vxsim@MYCOMPUTER): Fri Mar 16 10:32:51 2007
       Checking License ...OK
       Connecting to target agent... succeeded.
       Attaching C++ interface... succeeded.
       Attaching pecoff OMF reader for SIMNT CPU family... succeeded.

   • Note: Your Tornado registry must already be running. If you setup your Tornado registry to run as a Windows service it will show up as wtxregds.exe in the Processes tab of the Windows Task Manager. If it is not running, you will get something like this:
     

     tgtsvr (vxsim@MYCOMPUTER): Fri Mar 16 16:27:21 2007
         Checking License ...OK
     Cannot contact Wind Registry on host: localhost
     Target Server will exit

     To start the Tornado registry, run wtxregd.exe (not wtxregds.exe) from the command prompt:
     

     C:\Tornado2.2\host\x86-win32\bin>wtxregd

4. Now start the shell:
   

   C:\Tornado2.2\host\x86-win32\bin>windsh vxsim

5. Easy. Actually it took me a little while to figure out I needed to specify the VxWorks core file with the -c option for the tgtsvr command. If you don't do this, you will get the following error message:

   tgtsvr (vxsim@MYCOMPUTER): Fri Mar 16 10:31:37 2007
       Checking License ...OK
       Connecting to target agent... succeeded.
       Attaching C++ interface... succeeded.
       Attaching pecoff OMF reader for SIMNT CPU family... succeeded.
       Error: Couldn't open C:\Tornado2.2\vxworks: status = 0x2
   Error during target server core initialization
   Target Server will exit

   And if you forget to specify the target name, you will get:
   

   A target must be specified.
   Target Server will exit
