                     .CE

                     After you got the ">BKM>" prompt again continue with the 
                     instruction in the next section.

       3.2.5 Converting the bootrom_uncmp.hex to bootrom_uncmp.bin:

             3.2.5.1 Go to the menu and choose "Tools" and 
                    "Vision Flash Utility..." . 

             3.2.5.2 The "Flash Programming Window" will popup. Go to the 
                     "Files" tab, press the "Convert" button.

             3.2.5.3 The "File Convertion" window will popup. In the 
                     "Enter new start address" edit box type "0x0" and in the
                     "Enter new end address" edit box type "0xFFFFFFFF".
      
             3.2.5.4 Now press the "Convert" button. After the convert operation
                     finished, you will see it in the "Convert Result" section
                     press the "Close" button.
          
       3.2.6 Programming the SBC8260ATM Flash:

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

                     The 64MB SIMM Flash: "INTEL 28F640Jx (8192 x 8) 4 Devices"

                     The 2MB On Board FLASH: "AMD 29F016/17(2048 x 8) 1 Device"

                     ** Note: In order to use the On Board FLASH some jumpers 
                              and switches should be changed.

                     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".

             3.2.6.3 Now switch to the "Files" tab and press the "Add" button. 
                     The open dialogbox will popup, browse to 
                     "$(WIND_BASE)\target\config\wrSbc8260Atm\" 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.

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

             3.2.6.5 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 (JP13) port on the 
             the SBC8260ATM, 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, Connect a standard Ethernet cable to the the RJ45 (JP28)
             connector on the Fast Ethernet transceiver.

   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 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 SBC8260ATM FLASH" section how to program 
      the SBC8260ATM Flash, and instead of programming the "bootrom_uncmp.bin" 
      program the "vWARE.bin" file.
	  
    1. Connect your SBC8260ATM serial channel (COM1) to a host running terminal 
       program at 9600 baud rate (For example "HyperTerminal") using the 
       supplied serial cable.

    2. Connect your SBC8260ATM 100Base-T (JP28) 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 SBC8260ATM 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 desired delay value and press enter.

    7. Next 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: 24.42.124.92 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: 24.42.124.94 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:
