Both A/B partitioning and snapshot-based updating can roll back a failed OTA update. They reserve very different amounts of flash to do it, and the gap grows with the image.
Updating an embedded system reliably can be challenging. Often the devices are in the field in places where troubleshooting is painful if something goes wrong. Methods for failed update recovery are therefore often built into these systems. One of the most common strategies is what’s known as A/B partitioning, where the system is overprovisioned and […]
In embedded devices, achieving a comprehensive understanding of the storage stack can be a crucial step in managing the flash lifetime risks caused by write amplification. For embedded devices that operate in demanding field conditions, system integrity and data reliability are critically important. From a connected vehicle with a modern IVI system to an industrial […]
