  2. Build
    $ chmod a+x build.sh
    $ ./build.sh <target_board_name>
    
    target_board_name is specified for each board according to the following table:
    R-car-sk-target-board-name.png

    Depending on the performance of the host PC, it may take several hours for the build to complete.
    When the build completes successfully, you will see the following output:
    NOTE: Tasks Summary: Attempted 4704 tasks of which 31 didn't need to be rerun and all succeeded.
    
  3. Check the built images
    The built images are stored in the following:
     <target_board_name>/build/tmp/deploy/images/<target_board_name>/
  4. Write the images to the SD card
    Write the images to the SD card with reference to Loading kernel and rootfs via eMMC/SD card.
    18px <translate> Note:</translate> Please replace "core-image-weston" with "core-image-minimal".

Receive telemetry messages

  1. Procedure on the target board
    1. Turn on the target board
      1. Insert the SD card into the target board, and connect the LAN cable to it.
      2. Use a microUSB cable to connect the target board, connect a power supply to it, and connect to serial console.
      3. Power on.
        Short-press SW8 "Power" to switch the board on.
        If the board is attached to the CCPF board, short-press SW4 "Power" instead of SW8.
    2. Configure U-Boot to boot from SD card
      Refer to Configure U-Boot to boot from SD card.
    3. Connect to your IoT Hub
      Configure to connect to your IoT Hub.
      1. Add a write permission to "/etc/iotedge/config.yaml".
        $ chmod +w /etc/iotedge/config.yaml
        
      2. Set the "Primary Connection String" to device_connection_string.
        $ vi /etc/iotedge/config.yaml
          device_connection_string: "<ADD DEVICE CONNECTION STRING HERE>" ← ★
        
        18px <translate> Note:</translate> See Register an Azure Device for the "Primary Connection String".
      3. Remove a write permission from "/etc/iotedge/config.yaml".
        $ chmod -w /etc/iotedge/config.yaml
        
      4. Restart the IoT Edge daemon.
        $ systemctl restart iotedge
        
      5. Check that the IoT Edge daemon is running.
        $ systemctl status iotedge --no-page
        
        Azure-status-no-page.png

      6. Check that the following modules are deployed and are running.
        18px <translate> Note:</translate> It may take several minutes for the deployment to complete.
        $ iotedge list
        
      Azure-list.png

  2. Procedure on the Azure IoT Explorer
    Check that it receives telemetry messages from the IoT Edge Device.
    1. Install the Azure IoT Explorer.
      Download the installer from https://github.com/Azure/azure-iot-explorer/releases/tag/v0.14.1.
      18px <translate> Note:</translate> Use v0.14.1 because v0.14.7(latest version) does not receive any telemetry messages.
    2. Launch the Azure IoT Explorer.
    3. Get the "Primary Connection String" for the iothubowner.
      Go the IoT Hub page on the Azure Portal, click your "IoT Hub", "Shared access policies" from the side menu, and then click "iothubowner". Next, copy the "Primary Connection string".
      Azure-iot-exp-1.png
    4. Register your IoT Hub to the IoT Explorer
      Select the "IoT hubs" from the side menu of the Azure IoT Explorer, and click "+ Add connection".
      Paste the "Primary Connection string" you copied into the "Connection string" text box, finally click the "Save".
    5. Receive telemetry messages
      Select the "Telemetry" from the side menu, and click "Start".
      When a message is received, the following log is displayed.
