Installation

This article provides instructions on bootstrap and configuring the Linux system on Compute Module 4. The instructions below assume the Linux host environment. This article uses the term host - a Linux-based PC which configures the target (FIBER version 2 hardware).

Install Image​

  1. Download image

  2. Uncompress the image

  3. Install image to FIBER

    • Connect the PoE adapter to the target.

    • Connect the Mini USB cable between the host and the target.

    • Use a jumper to short the BOOT pins on the mainboard.

    • Shortly press the RESET tact switch on the rear side of the mainboard.

    • Now Compute Module 4 should start in the bootloader mode.

    • Remove the jumper from the BOOT pins on the mainboard.

  4. Flash the image

  5. Set up network connection

Network Connection Setup​

To start FIBER, follow the instructions below depending on your preferred connection method:

Wi-Fi Connection​

If you are connecting FIBER to your network via Wi-Fi, follow these steps:

  1. Connect your FIBER device to the PoE port of the PoE adapter.

  2. Wait for the device to establish a Wi-Fi connection with your network.

  3. Determine the IP address.

  4. Log in to the target (password fiber):

    ssh root@[ip address]

  5. Wait for approximately a minute for FIBER to establish a connection with your network.

Ethernet Connection​

If you are connecting FIBER to your network via Ethernet, follow these steps:

  1. Connect one Ethernet cable from the PoE adapter's LAN port to your router or switch.

  2. Connect another Ethernet cable from the PoE adapter's port to the FIBER device.

  3. Determine the IP address.

  4. Log in to the target (password fiber):

    ssh root@[ip address]

  5. Wait for approximately a minute for FIBER to establish a connection with your network.

Static IP Address Connection​

If you utilize a static IP address for FIBER connections, follow these steps:

  1. Update Configuration File (system section)

    • Set static_ip to True.
    • Replace the following placeholders with your network details: address (your static IP address), netmask, gateway, dns.

  2. Depending on the type of Ethernet or Wi-Fi connection, use the instructions for them above.

Additional information​

  1. Verifying Network Connectivity:

    Test the connection to the FIBER device from the host:

    ping [ip address]

  2. Checking device logs:

    If the FIBER device does not function as expected, you can view logs for troubleshooting:

    journalctl -u fiber-core.service

  3. Managing the service:

    Use the following commands to control the FIBER service:

    systemctl start fiber-core.service

    systemctl restart fiber-core.service

    systemctl stop fiber-core.service

  4. Restarting the device:

    To restart the FIBER device after making changes or for troubleshooting:

    • Using SSH:

      reboot

    • Press the physical reset button on the back of the device.
