Firmware Upgrade
Firmware upgrade is a staged task that allows for upgrading or downgrading the running, backup and bootloader firmware on supported devices.
To be able to use this feature, you must be connected to the internet, or have downloaded desire firmware ahead of time. If you have downloaded the firmware ahead of time, ensure it is placed in the firmware folder
Interface Components
The firmware upgrade interface is divided into five stages, Family, Version, Devices, Algorithm and Overview, where each is explained below:
Family
The first stage in firmware upgrade presents you with a choice of firmware families detected in the network. Where each family is listed as box with the title being the firmware family name, and the contents showcasing the latest version available within said family, as well as the total number of firmware versions present.
Click on the desired firmware family to proceeed to the next stage.
If only one firmware family currently exists in the network, this stage is skipped.
Version
The second stage in firmware upgrade presents a list of firmwares based on the selected family in the prior stage. These may either be marked as Validated, via a green checkmark, or as Unvalidated, via a yellow triangle with an exclamation point. A firmware version is considered Unvalidated when it originates from the users local disk, instead of being downloaded by WeConfig.
WeConfig makes no guarantees about the functionality or safety of Unvalidated firmware.
Additionally, this view will also indicate the download status of each firmware in the list. If the firmware is not already downloaded, as indicated in the picture above by the "Not downloaded" text
Click on the desired firmware version to proceeed to the next stage.
If only one firmware version exists in the selected family, this stage is skipped.
Devices
The third stage in firmware upgrade presents a list of devices compatible with the selected firmware version, where any matching devices already selected in the topology are preselected. The list will also display any possible issues or warnings related to firmware upgrade, such as a detected device downgrade in the example above.
Select the desired devices (either manually or using select all) and click "Confirm" to proceed to the next stage.
Algorithm
The fourth stage in firmware upgrade presents three options for the order-of-execution of the firmware upgrade sequence, the options are as follows:
| Option | Description |
|---|---|
| Optimized | Parallelizes firmware upgrade when possible according to network order. |
| Upgrade sequentially | Do not parallelize firmware upgrade, run them in displayed top-down order. |
| Upgrade in parallel | Attempt to do all firmware upgrades in parallel |
Click on the chosen algorithm option to proceed.
Unless a specific use-case demands otherwise, it is suggested to use the Optimized algorithm when you have a fully detailed connection map of the topology.
Overview
The fifth and final stage in firmware upgrade presents you with a list of planned actions for WeConfig to undertake. As can be observed in the example above, to take 198.18.1.1 to 5.23.0, WeConfig needs to upgrade it through the required versions of 5.21.1 and 5.22.1 before finally upgrading to 5.23.0.
Additionally, any remaining potential issues are also displayed on the devices here.
Global options
Atop the interface in stage 2-5 three checkboxes may appear, which slightly change the firmware upgrade procedure when checked, they are as follows:
| Option | Description |
|---|---|
| Only required steps | When unchecked, WeConfig will move through every intermediary version between the source and target version, when checked, WeConfig will only move through the versions considered nessecary |
| Install latest bootloader | When checked, WeConfig will always attempt to upgrade the bootloader if a newer one exists in the provided firmware package, otherwise, WeConfig will only upgrade the bootloader when nessecary |
| Skip Secondary | When checked, WeConfig will not upgrade the backup firmware on any of the devices, otherwise, it will |
