Firmware Update
The Firmware Update tab displays the current firmware version and provides tools for updating the device firmware.
Firmware Information
| Field | Description |
|---|---|
| Version | The currently running firmware version |
| Active Slot | The firmware slot currently booted (A or B) |
| Inactive Slot | The alternate firmware slot and its version |
The device uses an A/B slot scheme. Firmware updates are installed to the inactive slot, so the currently running firmware is never modified during an update.
Update Methods
File Upload
Drag and drop a .raucb firmware bundle onto the upload area, or click Choose File to select one from your computer.
URL Install
Enter an HTTPS URL pointing to a .raucb firmware bundle and click Install from URL. The device downloads and installs the firmware directly.
Update Modes
| Mode | Description |
|---|---|
| Single slot (default) | Installs firmware to the inactive slot only. After installation, click Reboot to Activate New Firmware to boot into the new firmware. |
| Both slots | Check the Update both slots checkbox before uploading. The device installs firmware to the inactive slot, reboots automatically, then installs to the second slot. |
Update Progress
During an update, the upload area is replaced by a progress bar and status message. The interface polls for status every 2 seconds.
After a successful single-slot update, a Reboot to Activate New Firmware button appears. After a successful both-slots update, a confirmation message is displayed.
If an error occurs, the error message is displayed below the firmware information.
