.IP "Running the VxWorks Boot ROM Program"

At this point, the on-board local flash memory is programmed with the new 
boot program.  To execute this new boot program, turn the board off and on, 
possibly disconnecting the visionPROBE in the process.  If the 
visionPROBE I/II or the visionICE I/II is still connected to the board, 
the processor is stopped at the first instruction to execute.  If either the 
visionICE or the JTAG probe are not connected, the boot ROM image will execute 
and prompt the user via the serial port to download a VxWorks image.

To load VxWorks, and for more information, follow the instructions in the 
.pG "Getting Started".


An alternative way to load vxWorks is through vWARE.

.SS "Using visionWARE to run VxWorks"
The following section explains how to launch VxWorks using visionWARE as a boot loader.

Complete the following steps:
	  
    1. Connect your SBCARM7 serial channel (COM1) to a host running a
       terminal program at 9600 baud (for example, '
       HyperTerminal') using the supplied serial cable.

    2. Connect your SBCARM7 100\10Base-T RJ45 connector (JP13) port to
       a network hub.

    3. Open a TFTP server and point to the location of the 'vxWorks.bdx'
       file. If you want to use the TFTP server that is supplied with
       visionWARE, go to the visionWARE directory on your host and 
	   locate the 'tftp' directory in the visionWARE root directory.  
       The 'tftp' directory contains an application called 'tftpd32.exe'. 
	   This application launches the TFTPD32 window. In the TFTPD32
       window, click the 'Settings' button. This invokes 
       'Tftpd32: Settings'. Go to the 'Base Directory' group and 
       type the full path to your VxWorks image inside the edit box,
       or use the 'Browse' button to navigate to your image.

    4. Power up your SBCARM7 and, from the serial terminal, press 
	   any key within 1 second to abort the boot script. This displays
       a '>BKM>' prompt.

    5. Type the 'shell' command and press enter. The following line 
	   appears: 'Boot Delay (seconds) = 6 >' . Specify the desired 
	   delay value and press enter.

    6. The next line is: ' Boot Script = >' . Type the boot script 
	   command. For example, if your host computer was named
      'BOS-GILH', you would type the following:
      
      "load \\\\BOS-GILH\vxWorks.bdx!launch 6000"

      and then press enter.
      
      Note(s):

        ** It is very important to keep the same space between the
           'load' command and the host name '\\\\BOS-GILH'.

        ** It is also very important to keep the same space between 
		   the 'launch' command and the '6000'.

        ** The host name should be the same as specified in the
           "Remote System 1 Name" line.
    
    7. The next line is "MAC Address = 00-A0-1E-08-04-9A >" . If you
       want to change the target MAC address, type it now and press
       enter, else just press enter.

    8. The next line is "IP Address = 0.0.0.0 >" . Type your target
       IP address. For example: 24.42.124.92, and press enter.

    9. The next line is "Subnet Mask = 0.0.0.0 >" . If you want to
       use a subnet mask, type it now and press enter, else just press
       enter.

   10. The next line is "Default Gateway = 0.0.0.0 >" . If you want
       to use a default gateway, type it now and press enter, else just
       press enter.

   11. The next line is "Remote System 1 Name = >" . Type the same 
       host name you specified in the 'Boot Script' line.

   12. The next line is "Remote System 1 IP = >" . Type your host 
       IP address. For example: 24.42.124.94 and press enter.

   13. Press enter after each of the following lines:
       "Remote System 2 Name = >"

       "Remote System 3 Name = >"

       "Remote System 4 Name = >"

   14. The following message appears:

       Saving changes will generate a reboot.
       Save Changes (y/n)?

       Press 'y' to save the changes.

The changes are now saved. The board will restart visionWARE and 
boot VxWorks. After a few seconds, the following messages appear:
