Please refer to our [Knowledge Base](https://support.crosscontrol.com/knowledge-base) for further information and
troubleshooting guides.

## Plug-in not available after installation

Verify that the plugin is activated in Qt Creator:

1. Open `Help` and select `About Plugins`.
2. Locate section `Utilities` in the list of plugins.
3. Verify that `LinXManager_FieldbusAccess` is available and loaded.
4. Verify that `LinXManager_DataEngine` is available and loaded.

## Application running but no value is updated

* Verify that Data Engine, Fieldbus Access and your application is running

    ``` console
    ps | grep dataengineserverApp
    2024 root 118m S /opt/bin/dataengineserverApp
    ```

    ``` console
    ps | grep fieldbusaccess
    2409 root 38068 S /opt/bin/fieldbusaccess /opt/bin/FieldbusAccess_Config
    ```

* Verify that the CAN interface is up. 
  * Run `ifconfig can0` in the terminal. Interface should list as "UP".
* Verify that correct node ID’s and addresses is configured in the configuration file.

## Check if Fieldbus Access starts with my configuration file

On the device, execute the following command:

``` console
ps | grep fieldbusaccess
2409 root 38068 S /opt/bin/fieldbusaccess /opt/bin/FieldbusAccess_Config
```

Fieldbus Access runtime is running with `/opt/bin/FieldbusAcces_ConfigFile.json` as it’s configuration file by default.
If a new configuration has been deployed and steps in [Update default Fieldbus Access configuration](usage.md) have
been followed, verify that the links points to the deployed configuration.

``` console
ls -l /opt/bin/FieldbusAccess_ConfigFile.json
/opt/bin/FieldbusAccess_ConfigFile.json -> /opt/Tutorial/bin/FieldbusAccess_ConfigFile.json
```

## Verify that LinX-Base runtime is installed on the Device

Execute the following command on the device

``` console
ls /opt/packages
```

In the list of installed component you should see "Linx-Base_<VERSION>_<ARCHITECTURE>"
