    \title Connecting Embedded Linux Devices

    You can connect embedded Linux devices to the development PC to run,
    debug, and analyze applications built for them from \QC.

    If you have a tool chain for building applications for embedded Linux
    devices installed on the development PC, you can add
    it to \QC. You can then select a \l{glossary-buildandrun-kit}{kit}
    with \uicontrol {Embedded Linux} device type to
    build applications for and run them on embedded Linux devices.

    To be able to run and debug applications on embedded Linux devices, you must
    add devices and select them in the \QC \l{glossary-buildandrun-kit}{kit}.

    You use a wizard to create the connections. You can edit the settings later
    in \uicontrol Tools > \uicontrol Options > \uicontrol Devices >
    \uicontrol Devices.

    You can protect the connections between \QC and a device by using an
    \l{https://www.openssh.com/}{OpenSSH} connection. OpenSSH is a
    connectivity tool for remote login using the SSH protocol. The OpenSSH
    suite is not delivered with \QC, so you must download it and install it
    on the development PC. Then, you must configure the paths to the tools in
    \QC. For more information, see \l {Configuring SSH Connections}.

    You need either a password or an SSH public and private key pair for
    authentication. If you do not have an SSH key, you can use the ssh-keygen
    tool to create it in \QC. For more information, see \l {Generating SSH Keys}.

    \note \QC does not store passwords, so if you use password authentication,
    you may need to enter the password on every connection to the device,
    or, if caching is enabled, at every \QC restart.

    To configure connections between \QC and an embedded Linux device and to
    specify build and run settings for the device:

    \list 1

        \li Make sure that your device can be reached via an IP address.

        \li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits >
            \uicontrol {Qt Versions} > \uicontrol Add to add the Qt version
            for embedded Linux.

        \li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits >
            \uicontrol Compilers > \uicontrol Add to add the compiler for
            building the applications.

        \li To deploy applications and run them remotely on devices, specify
            parameters for accessing the devices:

            \list 1

                \li Select \uicontrol Tools > \uicontrol Options >
                    \uicontrol Devices > \uicontrol Devices > \uicontrol Add >
                    \uicontrol {Generic Linux Device}
                    > \uicontrol {Start Wizard}.

                    \image qtcreator-screenshot-devconf-linux.png "Connection Data wizard"

                \li In the \uicontrol {The name to identify this configuration} field,
                    enter a name for the connection.

                \li In the \uicontrol {The device's host name or IP address} field,
                    enter the host name or IP address of the device.
                    This value will be available in the variable \c %{Device:HostAddress}.

                \li In the \uicontrol {The username to log into the device} field,
                    enter the username to log into the device and run the
                    application as.
                    This value will be available in the variable \c %{Device:UserName}.

                \li In the \uicontrol {The authentication type} field, select
                    \uicontrol Default to use the currently displayed private
                    key file for authentication. Select \uicontrol {Specific Key}
                    to use some other key, and enter the path to the file that
                    contains the private key in the field below. This value will
                    be available in the variable \c %{Device:PrivateKeyFile}.

                \li  Click \uicontrol {Next} to create the connection.

            \endlist

            All of these parameters can be edited later, as well as additional ones that the
            wizard does not show because there are sensible default values. One of these is
            the SSH port number, which is available in the variable \c %{Device:SshPort}.


        \li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits >
            \uicontrol Add to add a kit for building for the device. Select the
            Qt version, compiler, and device that you added above, and choose
            \uicontrol {Generic Linux Device} for the device type.

        \li To specify build settings:

        \list 1

            \li Open a project for an application you want to develop for the
                device.

            \li Select \uicontrol Projects > \uicontrol {Build & Run} to enable
                the kit that you specified above.

        \endlist

        \li Select \uicontrol Run to specify run settings. Usually, you can use
            the default settings.

    When you run the project, \QC deploys the application as specified by the
    deploy steps. By default, \QC copies the application files to the device.
    For more information, see \l{Deploying Applications to Embedded Linux Devices}.
