Firmware management API

Description

The VAPIX® Firmware management API describes how to manage the firmware of the Axis products in order to:

Retrieve the status for the current firmware.
Upgrade the firmware.
Rollback firmware to the previously installed version.
Restore configurations back to the factory defaults.
Reboot the Axis product.

Firmware rollback

The firmware rollback feature provides the option to undo a firmware upgrade. When using the feature, the firmware and its configurations will return to the state they were in before the upgrade.

There are several scenarios when a firmware rollback may be triggered:

The Axis products detects a problem when starting the newly upgraded firmware.
It may be externally requested through the rollback method.
A rollback timer expires. The time-out value can be provided in the upgrade method.
The Axis product is manually rebooted (e.g. power cycled).

Overview

Model

The API consists of a single CGI, firmwaremanagement.cgi

Identification

Property: Properties.FirmwareManagement.Version=1.3
API Discovery: id=fwmgr
Firmware: 7.40 and later

Obsoletes

The following CGIs are made obsolete by the firmwaremanagement.cgi:

firmwareupgrade.cgi: Upgrade
factorydefault.cgi: factoryDefault
hardfactorydefault.cgi: factoryDefault
restart.cgi: Reboot

Common examples

Upgrade firmware

Use this example to upgrade the Axis firmware. As part of the procedure, the product will also reboot.

In order to prevent an automatic firmware rollback when upgrading and the timeout argument is set, the user has to commit the upgrade by calling on the commit method. Should no timeout be available, the firmware will automatically be committed when the Axis product has completed its startup.

Upgrade without timeout:

1. Upgrade the firmware

pendingCommit=<string> Pending auto commit.

"started" The current firmware will be automatically committed once the device has finished booting, see Upgrade. This is only present if the active firmware is uncommitted and an automatic commit is pending.

Error codes

Error codes returned by this method are listed in General error codes.

Upgrade

note

Firmware upgrade is only allowed if the current firmware is committed. Any inactive firmware will be purged when an upgrade starts (even if the upgrade itself should fail) making a rollback to that firmware impossible. If you are downgrading to an older firmware version, you must set the factoryDefaultMode parameter to "hard".

Upgrade the firmware. After the Axis product has been upgraded with a new firmware it is rebooted as part of this method.

Request

Security level: admin
Method: POST

http://<servername>/axis-cgi/firmwaremanagement.cgi

The request shall be a multipart message, with the JSON message in the first part and the firmware file content in the second part.

The following table lists the JSON parameter for this CGI method.

Parameter	Type	Description
`apiVersion`	String	The requested API version in the format Major.Minor.
`context`	String	Optional context string. Client sets this value and the cgi echoes it back in the response.
`method`	String	`upgrade`
`params`	JSON object	Container for the method specific parameters listed below.
`factoryDefaultMode`	String	Optional. Reset parameters to their factory default values. `none` (default): Upgrade and preserve the current settings. `soft`: All parameters are set to their factory default values except those listed in factoryDefault. `hard`: All parameters are set to their factory default values. Note: All applications and ACAP:s are removed or restored to pre-installed versions on the "hard" and "soft" options.
`autoCommit`	String	Optional. Controls when the new firmware will be automatically committed by the device. `never`: The firmware is never committed automatically and must be committed via the commit method. `boot`: The firmware is committed when it starts booting. `started`: The firmware is committed when the device has finished booting. `default`: The same as `never` if `autoRollback` is not set to `default`, otherwise it is the same as `boot` as long as `factoryDefaultMode` is not `none`, or otherwise `started` if neither. Note: This parameter is ignored if the new firmware doesn't support automatic rollback.
`autoRollback`	String	Optional. Controls when the new firmware will automatically consider the upgrade failed and revert to the previous firmware. `never`: The firmware is never rollbacked automatically. However a rollback will still occur if the system encounters a major fault or if the power is interrupted before the firmware has been committed. A numeric value specifies the number of minutes after boot until the system automatically performs a rollback unless a commit (automatic or externally requested) has been performed. `default`: The same as `never` if `autoCommit` is not also set to `default`. Otherwise, the default is to automatically rollback after 10 minutes. Note: This parameter is ignored if the new firmware doesn’t support automatic rollback

Rollback

note

Only the most recent upgrade can be rolled back. Any inactive firmware is purged when an upgrade starts, making it impossible to rollback more than one step. Applications and their data are not rolled back.

Rollback the firmware along with the configuration settings to the state it was in before the most recent upgrade.

This method can be used regardless if the active firmware is committed or not. Rollback will not be available after a purge or a factory default.
