Connect a Target Device

Introduction​

This article describes how to connect a device to the Torizon IDE Extension. That allows you to use a connected SoM as the target for remote debugging and deployment of projects directly from Visual Studio Code. Also, it shows you how to manage SoMs' containers and images through the Docker VS Code extension.

info

The instructions provided in this article work for both Linux and Windows environments.

Prerequisites​

Engineering Mode​

When connecting to a device, the Torizon IDE Extension sets it up to be in Engineering Mode (Development Mode).

In Engineering Mode, some debugging and deployment features are enabled, affecting the following configurations:

  • Enable password or SSH key sharing between the SoM and the development computer.

  • Enable the Docker API broadcast over HTTP on the SoM.

  • Enable your development PC's IP as an insecure container registry. That is required for pulling container images (stored on your development PC) from the target device. That configuration is added to Torizon OS at /etc/docker/daemon.json as follows:

    daemon.json
    {
    "insecure-registries" : ["<your development PC's IP>"]
    }
  • Set up the Message of the Day (MOTD) to alert that the device is in engineering mode.

info

Those settings should only be used during the development phase. Those settings are erased when you flash your module with a new OS image.

Scan your Network and Connect a Target Device​

  1. Scan your network: Click the Torizon icon in the left menu bar to scan your local network for devices.

    caution

    The target device must be on the same network as the development machine.

    You can also rescan your network by clicking the Refresh Devices icon.

  2. Connect your target device: After the scan, expand the device entry and click Connect.

  3. Input the SoM's user and password: These credentials are the same you use for accessing your SoM from the command-line.

  4. Check if the connection was established: You can follow the progress in the footer of the VS Code window.

    After the connection, the device will be listed under CONNECTED DEVICES, and the footer will show the connection status.

Manually Add Devices​

In some network configurations, your device may not be detected. If that is your case, you can manually add devices by clicking the + icon and inputting the devices' IP.

If you do not know how to get your device's IP, see Scan your local network to find the board IP and MAC address.

Set a Torizon OS Device as Default​

The IDE extension automatically configures your project's settings.json file based on the default device. Therefore, always set a device as default when creating a new project or opening one from a different machine.

info

Even with multiple devices connected, the IDE Extension's tasks only target the default device.

The Extension uses the settings.json file to perform different tasks:

To set a device as default, proceed as follows:

  1. Create a container project

  2. Expand a connected device entry, and click Set Default:

    The bullseye icon indicates which device is being used as the default target by your project.

The Docker VS Code extension uses the default device as the Docker context for running containers. You can confirm that by checking the DOCKER_HOST environment variable in the Docker's view:

  1. Open the Docker's view (1).
  2. Click on the CONTEXTS tab (2).
  3. Check the IP address (3) of DOCKER_HOST.

Once a Torizon device is set as default, you can manage its containers, images, volumes and networks through the Docker VS Code extension.
