Update the DAL OS system firmware

Digi’s DAL OS firmware for Digi devices provides a managed, secure embedded operating system foundation that supports scheduled and ad-hoc updates to ensure device integrity and performance over time. DAL OS firmware can be updated locally using the device’s DAL OS Web UI console or the CLI console. Devices can be updated locally or remotely using Digi Remote Manager, which enables local updates on individual devices through the DAL OS Web UI or CLI consoles, and remote updates across multiple devices simultaneously using templates. For more information about updating firmware using Digi Remote Manager, see About the DAL OS firmware in the Cellular documentation portal.

The AnywhereUSB Plus operating system firmware images consist of a single file with the following naming convention:

platform-version.bin

For example, AnywhereUSB Plus-25.2.54.xxx

Certificate management for firmware images

The system firmware files are signed to ensure that only Digi-approved firmware load onto the device. The AnywhereUSB Plus device validates the system firmware image as part of the update process and only successfully updates if the system firmware image can be authenticated.

Downgrading

Downgrading to an earlier release of the firmware may result in the device configuration being erased.

Downgrading from firmware version 22.2.9.x

Beginning with firmware version 22.2.9.x, the AnywhereUSB Plus device uses certificate-based communication for enhanced security when connecting to Digi Remote Manager. If you downgrade your firmware from version 22.2.9.x to version 21.11.x or previous, your device will no longer be able to communicate with Remote Manager.

To remedy this issue, select the device in Remote Manager and select Actions > Reset Device Certificate.

    Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

  2. >Use the system firmware ota check command to determine if new modem firmware is available on the Digi firmware repository.
    > system firmware ota check
Current firmware version is 25.12
Checking for latest AnywhereUSB Plus firmware...
Newest firmware version available to download is '26.2.147.55'
Device firmware update from '25.12' to '26.2.147.55' is needed
>
  3. Use the modem firmware ota list command to list available firmware on the Digi firmware repository. 
    > system firmware ota list
25.12
26.2.147.55
>
  4. Perform an OTA firmware update:
    • To perform an OTA firmware update by using the most recent available firmware from the Digi firmware repository:
      1. Update the firmware: 
        > system firmware ota update
Downloading firmware version '26.2.147.55'...
Downloaded firmware /tmp/cli_firmware.bin remaining
