2. Install the SD Card, power up the board via the power jack or PoE and plug in the RJ45 Ethernet cable.
|
||||
3. Wait for all the front panel LEDs except the termination status LEDs to turn off. It can take a minutes or two for first boot. If it does not boot up, try to flash the SD Card again.
|
||||
4. Run `ssh <fast servo ip address> -p 3030` to ssh into fast-servo and run `linien-server run` to start the linien server.
|
||||
5. In the dev shell, run `linien` to launch the GUI. Add new device. Username is `root` and it does not take any password to log in. You leave the password field with any text.
|
||||
6. Select the newly added device and click connect in the GUI to connect and start the GUI.
|
||||
4. By default, linien-server starts up automatically. In case linien-server crashes, it will restart itself. Logs are stored in `/root/linien-server-log`. Here are some commands to interact with the linien-server service once you `ssh <fast servo ip address> -p 3030` into fast-servo.
|
||||
|
||||
| Description | Command |
|
||||
|------------------------------------------------------|-----------------------------------------|
|
||||
| Start the linien-server service | `linien-server start` |
|
||||
| Stop the linien-server service | `linien-server stop` |
|
||||
| Check if the linien-server service is running | `linien-server status` |
|
||||
| Set the linien-server service to start at bootup | `linien-server enable` |
|
||||
| Set the linien-server service not to start at bootup | `linien-server disable` |
|
||||
|
||||
4. In the dev shell, run `linien` to launch the GUI. Add new device. Username is `root` and it does not take any password to log in. You leave the password field with any text.
|
||||
5. Select the newly added device and click connect in the GUI to connect and start the GUI.
