If you are installing the Windows CE boot loader for the first time, or if you are restoring a boot loader that was corrupted, use the following procedure to download the Windows CE boot loader to the NEC Solution Gear 2-Vr4131 Development Kit.

To download the Windows CE boot loader to the NEC Solution Gear 2-Vr4131 Development Kit

  1. Turn off the Solution Gear 2-Vr4131.

    Note   Disconnect the power for a few minutes to drain the capacitive charge. This prevents problems when booting.

  2. Use the following settings for the SW2 switch.

    SW2-1 SW2-2 SW2-3 SW2-8
    Off On Off Off

    SW2 is the blue switch at the upper right corner of the CPU card.

  3. Connect a NULL modem cable to the debug port.

    Note   On the baseboard, the PMON debug serial port is on the bottom while the Windows CE debug serial port is on the top.

  4. Configure your terminal emulation software to use the following settings:

    Bits per second Data bits Parity Stop bits Flow control
    38400 8 None 1 None

  5. Turn on the Solution Gear 2-Vr4131.

  6. If PMON is configured to boot automatically, PMON counts down to 0 before booting. During this interval, select the terminal emulator window and press any key to break into PMON.

  7. Verify that you can see the OEM boot loader output.

    For more information, see OEM Boot Loader Output for the NEC Solution Gear 2-Vr4131 Development Kit.

  8. Type the following command to change the baud rate used by PMON to 115200:

    stty 115200

  9. Configure your terminal emulation software to use the following settings:

    Bits per second Data bits Parity Stop bits Flow control
    115200 8 None 1 None

  10. Type the following command to load the Boot.sre image into the NEC Solution Gear 2-Vr4131 Development Kit's RAM:

    load -htty0

  11. Send the Boot.sre file through the terminal emulation program as an ASCII text file.

  12. After Boot.sre downloads into RAM, type the following command to program the image into flash memory:

    flash 82000000 xxxxx 1c00000

    The xxxxx parameter denotes the size of the boot loader image. For example, if your boot loader image size is less than or equal to 0x20000 bytes, enter 20000 to denote your image size.

    You can use the Viewbin tool to determine the boot loader image size. For more information, see Viewbin Tool.

  13. Turn off the Solution Gear 2-Vr4131, and switch SW2-1 to the On position.

    This configures the device to run the boot loader at boot time.

  14. Configure your terminal emulation software to use the following settings:

    Bits per second Data bits Parity Stop bits Flow control
    38400 8 None 1 None

  15. Verify that the null modem serial cable is connected to the bottom serial port on the Solution Gear 2-Vr4131.

  16. Turn on the device and verify that you see the Windows CE boot loader output.

    To view the Windows CE boot loader output, see Windows CE Boot Loader Output for the NEC Solution Gear 2-Vr4131 Development Kit.
