	     	     program.

4. Running the VxWorks Boot ROM program:

   4.1 Disconnect visionPROBE II or the visonICE II if it still connected to 
       the board. In some case it can stop the processor at the first 
       instruction if it is still connected.

   4.2 Connecting the Ethernet channel and the serial channel:

       4.2.1 First, connect the supplied serial cable with the board. On 
             one side, connect the RJ11 connector to the COM1 (JP13) port on 
             the SBC8260. On the other side use an RJ11 to 9/25 Pin adapter to 
	     connect it to your host serial port. The UART device is set as 
             follows: 8 data bits, 1 stop bit, hardware handshaking, and parity 
             disabled. The serial console baud rate is 9600 bps.

       4.2.2 Second, plug the Fast Ethernet transceiver that came with the 
             board to the MII connector on the board (JP15). Connect a 
             standard Ethernet cable to the the RJ45 connector on the Fast 
             Ethernet transceiver.

   4.3 Launch a terminal program on the host side, and configure it according 
       to the following details: 8 data bits, 1 stop bit, hardware handshaking, 
       and parity disabled. The serial console baud rate is 9600 bps.

   4.4 To execute the boot program, reset the board by cycling the power or
       pressing the reset button. You should get the vxWorks boot count down on
       the terminal window. Press any key to stop the count down. Now follow the
       instructions in the "Getting Started" chapter of the 
       "VxWorks Programmer's Guide" for more details on 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 2 MByte 
On Board FLASH and FCC2 10/100BaseT Ethernet as default boot device and SMC1 as 
console device. The hard reset configuration word must be programmed separately 
at the flash base address of 0xFE000000 and at offsets 0x0, 0x8, 0x10 and 0x18, 
see chapter 5 Reset in the MPC8260 PowerQUICC II User's Manual.

.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: 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 SBC8260 FLASH" section how to program the 
      SBC8260 Flash, also you can skeep step 3.1.6 or 3.2.5 that explain how to
      convert the bootrom_uncmp.hex to *.bin, and instead of programming the 
      "bootrom_uncmp.bin" program the "vWARE.bin" file.
	  
    1. Connect your SBC8260 serial channel (COM1) to a host running terminal 
       program at 9600 baud rate (For example ' HyperTerminal') using the 
       supplied serial cable.

    2. Connect your SBC8260 100Base-T (JP15) port using the Fast Ethernet 
       Transceiver 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, insaide 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 SBC8260 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: "Command Channel = 0: serial >" Press enter.

    6. Next line will be: "Boot Delay (seconds) = 1 >". Here you need to 
       specify the disaierd 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: 
       "load \\host\vxWorks.bdx!launch 100000" . Where "host" 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 "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 "Prompt String = BKM >" . Press enter.
	
    9. Next line will be "MAC Address = 00-00-00-00-00-00 >" . If you want to 
       change the target MAC address, type it now and press enter, else press 
       just enter.

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

   11. 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.

   12. 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.

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

   14. 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.

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

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

   17. Next line will be "Remote System 4 Name =  >" . 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:
