2. Creating a bootrom_uncmp.hex:
   2.1 Launch Tornado II, go to the "Build" menu and choose the option 
       "Build Boot ROM...".
   2.2 the "Build Boot ROM" window will popup, in the "Select a BSP:" column
       choose the "wrSbc824x", and in the "Select an Image to build:" column
       choose "bootrom_uncmp.hex" and press the "OK" button.
   2.3 After the build process will finish successfully (You will see "Done" in
       the "Build window" without error), you will have the bootrom_uncmp.hex in
       your BSP directory "$(WIND_BASE)/target/config/wrSbc824x".

3. Programming bootrom_uncmp to SBC8240/8245 FLASH:
   If you are using visionCLICK please follow the instruction in section 3.1 
   if you are using SingleStep please follow the instruction in section 3.2
   
   3.1 Using visionCLICK:

       3.1.1 Install the visionPROBE II  or visionICE II and power it on. 
             Connect the JTAG interface cable from the visionPROBE II  or 
             visionICE II into the SBC8240/8245 board JTAG (JP26 The JTAG Port) 
             connector.

             Once all the connections have been made, power up the SBC8240/8245
             board and start the visionCLICK executable on the host.

       3.1.2 Configure the visionCLICK project: 
             The "Welcome To visionCLICK" window will appear .In this window 
             press on the "Configure" button, This will invoke "PROJECTS/LOAD" 
             window. In this window press on the '+' left to the 
             "PowerPC_C_Demo.prj".This will show you the project configuration. 
             Point with the mouse cursor on the "Microprocessors" option and 
             press the right button and choose the type of CPU you have on your 
             board. For example: "PowerPC->MPC82xx->MPC8240" for SBC8240 or
             "PowerPC->MPC82xx->MPC8245" for SBC8245. Verify that the 
             "Target Control" option point to visionPROBE for visionPROBE II or 
             visionICE for visionICE II, Also switch to the "Communications" 
             TAB and verify that the "Normal Port/Rate" & "Download Port/Rate" 
             suite your connection. for example: "LPT1"  for visionPROBE II. 
             Now press the "Save" button at the bottom of the window and after 
             it on the "Activate" button.

       3.1.3 Program visionPROBE II / visionICE II with the proper register 
             setting for the SBC8240/8245 board:

             Go to the "Tools" menu and select the 
             "Log Output/Playback Scripts" option. The "Record / Playback" 
             dialog box will popup. In this dialog box go to the 
             "Playback Commands From File" group and press on the "Browse" 
             button. Navigate your self to the location of the following  
             register file: "sbc8240_100MHz_64MB.reg" for the SBC8240 board 
             with 64MB SDRAM, "sbc8240_100MHz_16MB.reg" for the SBC8240 board 
             with 16MB SDRAM, "sbc8245_100MHz_64MB.reg" for the SBC8245 board 
             with 64MB SDRAM. The files located in the visionCLICK 
             installation. After choosing the register file press on the "Open" 
             button to confirm the selected reg file. You will return back to 
             the "Record / Playback" dialog box. Now press on the "Start" 
             button located in the same group. In the "Terminal" window you can 
             see that the visionCLICK is running the script. When visionCLICK 
             will finish the playback you will get back the ">BKM>" or the 
             ">ERR>".

       3.1.4 Get into Background Mode: 
             Execute the "IN" command to reset the board and initialize it with 
             the register setting.

             .CS
             IN
             .CS

             This command is the reset command to initialize the board.

       3.1.5 Converting the bootrom_uncmp.hex to bootrom_uncmp.bin:

              3.1.5.1 In visionCLICK, choose "Convert Object Modules" from the 
                      "Tools" menu. The "CONVERT BINARY AND SYMBOL OBJs" dialog 
                      box will pop up.Select "All Files" in the "Files of Type" 
                      box. Go to the "Select Input Object Module To Convert" 
                      group and navigate to the file "bootrom_uncmp.hex" 
                      located in: 
                      "$(WIND_BASE)/target/config/wrSbc824x/bootrom_uncmp.hex"

              3.1.5.2 In the group "Binary Downloadable Objects Modules" check 
                      the "Create Flat BIN File For Flash Programming". 
                      "In Range Of 0x" editbox, enter 0 for the start address, 
                      and in the "To 0x" editbox, enter "FFFFFFFF".

              3.1.5.3 Make sure that all the other check box are unchecked. 
                      Press the "Convert" button. Close the terminal window 
                      when the conversion completes.

       3.1.7 Programming the SBC8240/8245 Flash:
             In visionCLICK, select "Program Flash Devices" from the Tools 
             pull-down menu. This will invoke the "TF FLASH PROGRAMMING" 
             window. If you are not using visionCLICK, you can also invoke 
             this window using the "visionICE Utilities Panel" and follow the 
             steps below:

             3.1.7.1 Click the "Select" in the "Flash Card or PC Host File 
                     Name and Path" group. The "CHOOSE A FILE FROM HOST PC" 
                     dialog box will popup. In the edit box enter the full path 
                     to the location of the "bootrom_uncmp.bin", or use the 
                     "<--Browse" button to browse to the file location. Go to 
                     the "+/- Bias" group and enter the number "FFF00100" in 
                     the edit box. Now click the "OK" button, this will bring 
                     you back to the "TF FLASH PROGRAMMING" dialog box. 

             3.1.7.2 In the "Programming Algorithm" group in, the edit box 
                     press on the "Select" button, and select one of the 
                     following Flash devices:

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

             3.1.7.3 Set the proper address of the Flash to "FFF00000", check 
                     the "Erase All" radio button,and set the 
                     "Available RAM Workspace" setting to "00000000", set the 
                     "Bytes Of Target RAM Required" to "60000".

             3.1.7.4 Press the "Erase and Program" button.

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

   3.2 Using SingleStep for vision:

       3.2.1 Install the visionPROBE II  or visionICE II and power it on. 
             Connect the JTAG interface cable from the visionPROBE II  or 
             visionICE II into the SBC8240/8245 board JTAG (JP26 The JTAG Port) 
             connector.

             Once all the connections have been made, power up the SBC8240/8245
             board and start the SingleStep for vision executable on the host.

       3.2.2 Configure the SingleStep project: 

             3.2.2.1 Go to the "File" menu and choose the 
                     "Start Debug Session..." .
   	   
             3.2.2.2 The "Debug" dialog box will popup, In the "Connection" tab
                     choose the visionPROBE option & the correct LPT port if 
                     you are using visionPROBE, or visionICE & enter the 
                     emulator IP address if you are using visionICE.
			  
             3.2.2.3 In the "Processor" tab choose the "MPC8240" or "MPC8245".

             3.2.2.4 In the "Register" tab choose the option 
                     "Use vision-style register window with REG file" and then
                     browse to the location of the file 
                     "sbc8240_100MHz_64MB.reg" for SBC8240 board with 64MB 
                     SDRAM, "sbc8240_100MHz_16MB.reg" for SBC8240 with 16MB
                     SDRAM, "sbc8245_100MHz_64MB.reg" for SBC8245 with 64MB
                     SDRAM. The "sbc8240_100MHz_64MB.reg",
                     "sbc8240_100MHz_16MB.reg", "sbc8245_100MHz_64MB.reg"
                     files should be in the SingleStep registers directory.

             3.2.2.5 In the "File" tab choose the "Debug without a file" 
                     option.

                     prompt in the window will be ">BKM>". If the prompt is
                     ">ERR>" execute the "IN" command to reset the board and 
                     initialize it with the register setting.

                     .CS
                     IN
                     .CS
                     This command is the reset command to initialize the board. 
                     After you got the ">BKM>" prompt again continue with the 
                     instruction in the next section.
