Objective

The objective of this article is to go over the firmware automatic fallback mechanism in the RV34x series routers.

Applicable Devices | Software Version

Introduction

The RV34x series router includes two firmware images in the flash to provide an automatic fallback mechanism. If the active firmware version running on an RV34x router is exhibiting issues, it should be possible to revert to the prior version using the automatic fallback mechanism.

When the router is updated, the prior firmware version that was running on the router is kept as an inactive image. If the router fails to boot five times in a row, this is interpreted as a firmware issue, and the router will revert to the inactive image and boot from it.
