\sh 2. Flashing the bootrom image using visionClick 7.11a (or above) or UBOOT 

   There are two flash banks on the cds85xx reference board. By default, 
   Freescale preprogram the UBOOT on one of flash bank with Carrier Card 
   SW2[12]=01. This section will describe how to program vxWorks's bootrom
   onto another flash bank by using WindPower ICE or UBOOT (if available).
   
   2.1 Using visionCLICK 7.11a (or above required):
       
       NOTE: Make sure the Carrier Card's SW2[12] are set to 00 (OFF).
                If SW2[12]=01, the UBOOT bootloader will be erased!

       2.1.1 Creating a bootrom_uncmp.hex:
             Under the cds85xx BSP directory, type "make bootrom_uncmp.hex"; 
             or Using Project Facility to build a bootrom_uncmp.hex.

       2.1.2 Install the WindPower ICE and power it on.
             Connect the JTAG interface cable from the WindPower ICE into the 
             cds85xx  board JTAG (in CPU card) connector.

             Once all the connections have been made, power up the cds85xx 
             board and start the visionCLICK executable on the host.

       2.1.3 Configure the visionCLICK 7.11a (or above) 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. If "PowerPC->MPC85XX->" does not have MPC8541 or MPC8555, 
             choosing MPC8560 instead. Verify that the "Target Control" option 
             point to WindPowerICE for WindPowerICE. Now press the "Save" 
             button at the bottom of the window and after it on the "Activate" 
             button.

       2.1.4 Load the proper cds85xx register setting for Wind Power ICE:

             Press "Communications" TAB, Set up the "Ethernet/Port#" and "IP Address" 
             for the communication. For Ethernet communication, the "Ethernet/Port#" 
             is set to "NET" and "EST". The "IP address" is the IP address of the 
             Wind Power ICE. Now Press the "Connect" button, a connection message 
             should show up on the message box, such as " Connected To WIND POWER 
             ICE Over Socket 192.168.24.3:1234"  

             In the "Terminal" window, you will see ">ERR>" or ">BKM>", set the target
             to be MPC8555 or MPC8541. For MPC8555, type "cf tar 8555"; and For mpc8541
             type "cf tar 8541".

             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 to the location of the register file of the
             cds85xx.reg. The file can be found in the BSP
             installation directory . 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>". If the ">ERR>" is returned in the "Terminal" window,
             make sure the target board is power up, and type "inn" in the 
             "Terminal" to get to the ">BKM>". 

       2.1.5 Converting the bootrom_uncmp.hex to bootrom_uncmp.bin:

              2.1.5.1 In visionCLICK, choose "Convert Object Modules" from the
                      "Tools" menu. The "CONVERT BINARY AND SYMBOL OBJs" dialog
                      box will pop up. Go to the "Select Input Object Module 
                      To Convert" group and navigate to the file 
                      "bootrom_uncmp.hex" located in "$(WIND_BASE)/target
                       /config/cdcs85xx/bootrom_uncmp.hex"

              2.1.5.2 In the group "Binary Downloadable Objects Modules" check
                      the "Create Flat BIN File For Flash Programming".
                      "In Range Of 0x" editbox, enter 0x0 for the start
                      address, and in the "To 0x" editbox, enter "FFFFFFFF".
                      Note that if the non-hex version bootrom_uncmp is used,
                      the start address should be 0xd00000 instead.

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

       2.1.6 Programming the cds85xx Flash:
             In visionCLICK, select "Program Flash Devices" from the Tools
             pull-down menu. This will invoke the "TF FLASH PROGRAMMING"
             window:

             2.1.6.1 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 "FFF00000" in
                     the edit box. Now click the "OK" button, this will bring
                     you back to the "TF FLASH PROGRAMMING" dialog box. 

                     NOTE: The bootrom_uncmp.bin used in this step was created 
                           in the step 2.1.5. It is the file converted from the
                           bootrom_uncmp.hex by using visionCLICK converting tool. 
                           It is not the bootrom_uncmp.bin that you may create by 
                           using Tornado's Project Facility or typing 
                           "make bootrom_uncmp.bin" in the cds85xx BSP directory.

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

                     AMD 29LV64xDx[4096 x 16] 1 Device  

             2.1.6.3 Check the box of "Initialize Target Prior To Erase and/or Program"

             2.1.6.4 Set the Base Address of the Flash to "FFF00000", set 
                     the "Erase to" "FFFFFFFF", and set the
                     "Available RAM Workspace" setting to "00005000", set the
                     "Bytes Of Target RAM Required" to "3944".

             2.1.6.5 Press the "Erase and Program" button.

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


    2.2 Using UBOOT to flash the vxWorks's bootloader:
 
        Following instructions assume UBOOT is available on the reference 
        board, and assume FLASH base address of the second flash bank is set 
        to 0xFF00000 by UBOOT:
         
        2.2.1 Create a bootrom_uncmp.bin:
              In the BSP directory, type "make bootrom_uncmp.bin"; or
              Using Tornado's Project Facility to build a bootrom_uncmp.bin.

        2.2.2 Configure reference board and TFTP server:

              2.2.2.1 Set the Carrier Card's switch 2: SW2[12]=01. Bit 1 
                      is off and bit 2 is on. This allows UBOOT boot up 
                      the target.

              2.2.2.2 Connect a terminal to the serial port of the carrier 
                      card by using a NULL modem serial cable. Terminal parameters 
                      should be set to 115200bps, 8 data bits, no parity, and 
                      1 stop bit; Connect the Ethernet ports of the carrier 
                      card to the network.

              2.2.2.3 Set up a TFTP server in the host; copy the bootrom_uncmp.bin 
                      to the directory from which the TFTP client can download.

        2.2.3 Configure UBOOT:

              Power up the cds85xx board and hit any key in the terminal 
              to stop the autoboot of UBOOT. Set up IP addresses for this 
              target and the server. For example:

              =>setenv serverip 192.168.24.10 
              =>setenv ipaddr 192.168.24.30 
              =>saveenv 
              
              In this example, 192.168.24.10 is the IP address 
              of the TFTP server, 192.168.24.30 is the IP address 
              of the cds85xx reference board. You may also need to set up 
              a gateway and netmask if the TFTP server and the target board are not
              in the same subnet. Using "printenv" to find out other UBOOT 
              environment variable setup. "saveenv" will save the new 
              parameters on the flash.     

        2.2.4 Download and program the bootrom_uncmp.bin:

              2.2.4.1 Download the bootrom_uncmp.bin to the memory at 0x100000:

                      => tftp 100000 bootrom_uncmp.bin
          
              2.2.4.2 (optional) Back up the 1MB flash area from FF700000: 

                      NOTE: It is possible that this area contains other 
                            application such as EDINK OS. You may want to back 
                            it up before erasing. For example: 

                      => cp.b ff700000 ff300000 100000

                      to back up 1 MB FLASH from 0xFF700000 to 0xFF300000

              2.2.4.3 Erase the flash from FF700000 to FF7FFFFF:

                      => erase ff700000 ff7fffff

              2.2.4.4 Program the bootrom_uncmp.bin to the flash.

                      => cp.b 100000 ff700000 100000

              2.2.4.5 Power down the target board when flashing is done.

        2.2.5 Configure the cds855x boards to use vxWorks's boot ROM

              Set the Carrier board's switch 2: SW2[12]=00. Both bit 1 
              and 2 of switch 2 of the Carrier Card are off.

\sh 3. Running the VxWorks Boot ROM program

   3.1 Disconnect the WindPowerICE if it is still connected to the
       board, because if connected, it can stop the processor at
       the first instruction in some cases.

   3.2 Connecting the Ethernet channel and the serial channel:

       3.2.1 Connect the serial port in the carrier card to the host by 
             using a NULL modem serial cable.

       3.2.2 Second, connect the RJ45 ethernet cables to the TSEC ports
             adjacent to the serial port in the carrier card.
   
   3.3 Launch a terminal program on the host, and configures it according
       to 8 data bits, 1 stop bit, no hardware handshaking, and parity
       disabled. The baud rate is 9600 bps.

   3.4 If the board is not already powered off, turn it off momentarily.
       Power on the board,  you should see characters printed to the terminal 
       window, counting down to boot. 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 detail on how to configure vxWorks.
