  • Article

Before downloading the Ethernet boot loader, determine if the OEM boot loader is on the NEC Solution Gear 2 Series Development Kit. For more information, see OEM Boot Loader Output for the NEC Solution Gear 2 Series Development Kit.

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

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

  1. Turn off the NEC Solution Gear 2 Series Development Kit.

  2. Move the jumper from J15 to J35 to cause PMON to execute from PROM at boot time.

  3. Turn on the NEC Solution Gear 2 Series Development Kit.

  4. Type the following command to change the baud rate used by PMON to 38400:

    stty 38400

  5. 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

  6. Type the following command to load the Eboot.sre image into the NEC Solution Gear 2 Series Development Kit's RAM:

    load -htty0

  7. Send the Eboot.sre file through the terminal emulation application as an ASCII text file.

  8. Once Eboot.sre has been downloaded, type the following command to program the image into flash memory:

    flash 87F80000 xxxxx 1c00000

    Note   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 0x10000 bytes, you should enter 10000 to denote your image size. You can use the Viewbin tool to determine the boot loader image size. For more information, see Viewbin Tool.

  9. Turn off the NEC Solution Gear 2 Series Development Kit and then remove the jumper from J35 and put it on J15. This configures the device to run the boot loader at boot time.

  10. Verify that your terminal emulation software is configured using the following settings:

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

  11. Verify that the null modem serial cable is connected to the top serial port on the NEC Solution Gear 2 Series Development Kit.

  12. 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 Series Development Kit.
