Built on a vision that the latest software is the most secure, software updates are central to the FoundriesFactory security story. What happens, however, when software delivery is compromised? Is recovery complicated? Enter TUF key rotation!
The days of building monolithic embedded Linux systems are coming to an end. Security vulnerabilities, both on the software and hardware side are driving the embedded industry to adopt new ways to develop these systems. The writing has been on the walls for a while now, and this shift away from monolithic applications to microservices has been happening in the cloud for many years. The “internet of things” and “edge” computing have brought cloud developers closer to embedded systems than ever before.
Earlier this year, I found myself pushing the idea of an “anonymous mode“ for the Aktualizr project which is the OTA agent running in the LMP. This turned into “aktualizr-lite” and has recently become the default OTA agent used by the LMP. This article explains what aktualizr-lite is and why we are using it.
Continuing with the OTA blog series part one and part two, this article shows you how to deploy OTA Connect using the OTA Community Edition into Google’s Kubernetes Engine (GKE). After completion of these instructions, you’ll have an OTA Connect server available on the internet with a single QEMU device registered to it.
One of the first big decisions we had to make for the Linux microPlatform was our Over-The-Air Update (OTA) strategy. This decision required a lot of time, meetings, beer, and coffee. This article is the first of a small series explaining our recommended approach to OTA for the LMP. This article explains how and why we ultimately chose OTA Connect and its open source deployment project OTA Community Edition.
In this blog we describe how to use the Zephyr microPlatform and the in-tree Zephyr samples to build, flash and perform an over the air (OTA) update of a Zephyr application over Bluetooth Low Energy (BLE). This demonstration uses the DFU support within Zephyr provided by mcumgr.
