             3.2.4.4 Now press the "Convert" button. After the convert operation
                     finished, you will see it in the "Convert Result" section
                     press the "Close" button.
          
       3.2.5 Programming the SBC8240/8245 Flash:

             3.2.5.2 In the "Flash Programming Window" window. Go to the 
                     "Configuration" tab, & choose the following Flash device:

                     The 512KB On Board FLASH: "AMD 29F040 (512 x  8) 1 Device"

                     In "Flash Bank" group for the "Start:" enter "FFF00000". 
                     In the "RAM Workspace" group for the "Workspace Start at:" 
                     enter "00000000" and for the "Workspace Size:" enter 
                     "60000".

             3.2.5.3 Now switch to the "Files" tab and press the "Add" button. 
                     The open dialogbox will popup, browse to 
                     "$(WIND_BASE)\target\config\wrSbc824x\" and choose the 
                     "bootrom_uncmp.bin" file. Now after getting back to the 
                     "Files" tab you will see the full path to the selected 
                     file in the "Binary Files" group. Move the mouse curser 
                     above the line that showing the full path in the  
                     "Binary Files" group and press the right button to mark 
                     this line. Now press the "Toggle Enable" button to select 
                     this binary file. Make sure that the line is still marked, 
                     and press the "Edit" button on the right. The "File Edit" 
                     dialog box will popup. In the "Enter new start address" 
                     edit box enter "0xFFF00100" and press the "OK" button.

             3.2.5.4 Now go to the "Program" tab and press the "Erase/Program" 
                     button.

             3.2.5.5 Now the Flash memory is programmed with the new boot program.

4. Running the VxWorks Boot ROM program:

   4.1 Disconect visionPROBE II or the visonICE II if it still connected to the 
       board, because it still connected to the board in some case it can stop 
       the processor at the first instruction.

   4.2 Connecting the Ethernet channel and the serial channel:

       4.2.1 First, connect the supplied serial cable with the board. On 
             one said connect the RJ11 connector to the COM1 (JP31) port on the 
             the SBC8240/8245, and on the other said use the RJ11 to 9/25 Pin 
             addapter to connect it to your host. The UART devices is set as 
             follow: 8 data bits, 1 stop bit, hardware handshaking, and parity 
             disabled. The serial console (9600 bps).

       4.2.2 Second, plug the Intel PRO100B/S PCI NIC in the PCI slot on the 
             carrier board and connect a standard Ethernet cable to the NIC.

   4.3 Launch a terminal program on the host said, and configures it according 
       to the following details: 8 data bits, 1 stop bit, hardware handshaking, 
       and parity disabled. The serial console (9600 bps).

   4.4 Now to execute this new boot program turn the board off,and on. and you 
       should get the vxWorks boot count down on the terminal window. Press any
       key to stop the count down. Now follow the instruction in the 
       instructions in the "Getting Started" chapter of the 
       "VxWorks Programmer's Guide." for more detail how to configure vxWorks.

.SS "Default configuration"
bootrom_uncmp.hex is provided with this BSP. The bootrom_uncmp is configured to 
a ROM base address of 0x0 and includes, also it's configured to use the 512KB 
On Board FLASH and FEI 10/100BaseT Ethernet as default boot device and COM1 as 
console device.

.SS "Using visionWARE to run VxWorks"
The following section will explain how to launch VxWorks using visionWARE as a 
boot loader. Please follow the steps below:

Note(s): - Before using vsionWARE you need to verify that visionWARE is 
           programmed to you FLASH. If visionWARE is not exist on your FLASH, 
	   please see "Programming bootrom_uncmp to SBC8240/8245 FLASH" section 
           how to program the SBC8240/8245 Flash, and instead of programming 
           the "bootrom_uncmp.bin" program the "vWARE.bin" file.

         - vWare 1.10 is using the NetGear NIC by default so the VxWorks image 
           need to be compiled with the PNIC169 driver. vWare 2.00 is using the
           Intel 82559 NIC by default so the VxWorks image need to be compiled
           with the FEI82557 driver.
	  
	1. Connect your SBC8240/8245 serial channel (COM1) to a host running 
           terminal program at 9600 baud rate (For example "HyperTerminal") 
           using the supplied serial cable.

	2. Connect your SBC8240/8245 100\10Base-T (On the PCI Ethernet card) 
           port to a network hub.

	3. Open 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, inside the visionWARE 
           root directory you will find "tftp" directory that contain 
           application called "tftpd32.exe" . Run this application and the 
           TFTPD32 window will popup. In the TFTPD32 window press on the 
           "Settings" button. This will invoke the "Tftpd32: Settings". Go to 
           the "Base Directory" group and inside the edit box type the full 
           path to your vxWorks image, or use the "Browse" button to navigate 
           to there.

	4. Power up your SBC8240/8245 and press any key within 3 seconds from 
           the serial terminal to abort the boot script. This will display a 
           ">BKM>" prompt.

	5. Type the "shell" command and press enter. Now you should get the 
	   following line: "File System Sectors (256K each) = 8 >" Press enter. 

	6. Next line will be: "Boot Delay (seconds) = 1 >" . Here you need to 
	   specify the desired delay value and press enter.

	7.Nex line will be: "Boot Script = >" . Here you need to give the boot 
	  script command.Please type the following if you are using vWARE 1.10:
	  
	  "load \\host\vxWorks.bdx!osboot RAM!go 100000" . Where "host" or if 
          you are using vWARE 2.0 please type the following:

	  "load \\host\vxWorks.bdx!launch 100000"

	  is the host name, and press enter.
	  
	  Note(s):

          ** It is very important to keep the same space between the "load" 
             command and the host name "\\host".

          ** It is very important to keep the same space between the "osboot" 
             command and the "RAM". or between the "launch" command and the
	     "100000"

	** The host name should be the same as specified in the 
           "Remote System 1 Name" line.
	
	8. Next line will be "MAC Address = 00-A0-11-22-23-E8 >" . just press 
           just enter.

	9. Next line will be "IP Address = 0.0.0.0 >" .Type your target IP 
           address.  For example: 192.168.199.0 and press enter.

       10. Next line will be "Subnet Mask = 0.0.0.0 >" . If you want to use 
           subnet mask, type it now and press enter, else just press enter.

       11. Next line will be "Default Gateway = 0.0.0.0 >" . If you want to 
           use default gateway, type it now and press enter, else just press 
           enter.

       12. Next line will be "Remote System 1 Name = >" . Here you need to 
           type the same host name you specified in the "Boot Script" line.

       13. Next line will be "Remote System 1 IP = >" . Here you need to type 
           your host IP address. For example: 192.168.199.1 and press enter.

       14. Next line will be "Remote System 2 Name =  >" . Just press enter.

       15. Next line will be "Remote System 3 Name =  >" . Just press enter.

       16. Next line will be "Remote System 4 Name =  >" . Just press enter.

       17. If you are using visionWARE 1.10 this will be the next line will 
           "Command Channel = 0: Serial >" . Just press enter. If you are using 
           visionWARE 2.00 this will be the first line, again just press enter.

       18. Now you will get the following message: 

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

           Press 'y' to save the changes.

       19. Now the changes are saved and the board will restart visionWARE and 
           boot vxWorks, after a few seconds you will get the following 
           messages:
