Troubleshooting the balenaFin


When using a balenaCloud provisioned device, if the balenaFin does not appear in the balenaCloud dashboard upon powering the device on, you may want to check the list below for potential issues.

  • Check that the balenaOS image flashed to the Fin has the correct SSID and password for your WLAN network

    • A pattern of 4-blinks on the ACT status LED indicates that the Fin cannot connect to a network
  • Ensure that the WLAN radio physical switch (mapping 33) is set to the OFF position if you are not using an external antenna
  • Verify that the power supply can maintain a minimum of 6 V (ideally 1.5 A or above) when powering the device from the Phoenix (mapping 23) or Barrel Adapters (mapping 24)

    • If USB1 ON and USB2 ON Status LEDs (mapping 18 & 23) are not turned ON, it is an indicator that the power supply may be insufficient for powering the Fin
    • The board may still power on if a low current or voltage is supplied, however the peripherals such as the Ethernet may not function correctly.
