  1. Download and install either the Etcher (recommended) or Win32DiskImager tool from the following locations. This will be used to write the OS .img file to the Compute Module:

    https://etcher.io/

    https://sourceforge.net/projects/win32diskimager/

  2. Download and install the Compute Module boot installer. This will install Windows drivers for accessing the Compute Module.

    https://github.com/raspberrypi/usbboot/raw/master/win32/rpiboot_setup.exe

  3. Power up the Compute Module in USB boot mode:

    1. Make sure the USB cable is directly connected between the host PC and the display.

      Do not use a USB extender cable or hub between the host PC and the display. Use as short a USB cable as possible.

    2. On the NEC display select the [COMPUTE MODULE] video input.

    3. Press MENU on the IR remote control to open the OSD menu.

    4. Highlight the [C MODULE] menu and press SET.

    7. Select [SERVICE MENU].

    8. Select [SETTING LOCK] and then select [OFF].

    9. Enter the passcode. The default is 0 0 0 0.

    10. Select [USB BOOT MODE] and then select [ENABLE].

    11. It is also recommended setting [SHUTDOWN SIGNAL] to [DISABLE] and [WDT] to [DISABLE] during programming.

    12. Exit two levels and navigate to the [POWER] item on the [C MODULE] menu.

    13. Select [POWER SUPPLY] and then select [ON].

    Important: If the display goes into standby mode or Compute Module is powered off and on, it will automatically cancel USB BOOT MODE. Be sure to check that the boot mode is as intended if the process needs to be restarted.

  4. Run the Win32DiskImager or Etcher tool and select the downloaded OS .img file from step 4 of the previous instructions (for downloading the .img file from the Sharp NEC Display Solutions website).

    If using Etcher:

    1. Launch the Etcher application.

    2. Select the downloaded OS .img file as the source image.

    3. The Compute Module should automatically appear as the destination drive.

    4. Click “Flash!” to begin writing and verifying the image. This process should take approximately 5 to 15 minutes.

    5. When finished, the drive should contain the boot files for the OS.

    If using Win32DiskImager:

    1. Run the Compute Module boot application “rpiboot”, installed on the “Raspberry Pi” Windows Start menu. A window should appear with “Waiting for BCM2835/6/7”.

      Note: The Compute Module boot installer makes the Compute Module appear as a USB mass storage device to Windows. This step must be performed each time the Compute Module is placed into USB Boot Mode and powered on.

      The “rpiboot” command window should show some text and disappear.

      A new mass storage device should show as a new drive letter on the host PC. Windows may display a message saying the device needs to be formatted before use – ignore this message as it will be formatted by imaging it.

      See the “Troubleshooting” section on page 58 of this guide if a new mass storage device doesn’t appear.

    2. Run the Win32DiskImager tool and select the downloaded OS .img file.

    3. Select the new drive as the Target Device. Make sure the correct drive is selected as all data will be overwritten.

    4. Write the file to the Compute Module. This should take approximately 5 to 15 minutes.

    5. When finished, the drive should contain the boot files for the OS.

    Note: The display may go into a power save mode because there is no signal from the Compute Module (the power led will flash green). The internal Compute Module will remain powered on and can be flashed.

    Important: If the display or Compute Module is powered off and on, it will automatically cancel USB BOOT MODE. Make sure the boot mode is as intended if the process needs to be restarted.

  5. The Compute Module in the display can now be restarted in normal mode to boot the device:

    1. On the NEC display select the COMPUTE MODULE video input.

    2. Navigate to the COMPUTE MODULE menu on the OSD.

    3. Navigate to the SERVICE MENU item on the COMPUTE MODULE menu.

    4. If the USB BOOT MODE setting is still set to ENABLE change it to DISABLE.

    5. Navigate to the POWER item on the COMPUTE MODULE menu.

    6. Select POWER SUPPLY to OFF.

    7. Wait for power to the Compute Module to be shutdown. When navigating back to the same menu item it should now show POWER SUPPLY OFF.

    8. Select POWER SUPPLY to ON.

  6. The boot-up sequence for the NEC MediaPlayer should be seen on the screen.

Reinstalling on a Compute Module 4

Download the image installer:
