PKI Hacking for Fun and Profit

Products often need to talk to third party services like AWS. Many times, the best bad option available is to copy some type of API key to the device's file system. As an embedded engineer, I work under a simple assumption: > Someone will eventually hack my device This article explores a way to provision devices without API keys.

How We Chose a Software Update System

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.

180 days

It's March 30, 2018, Good Friday, and it has been 180 days since we started Foundries.io. In this time, we established our initial infrastructure, created the first microPlatform products and, on March 27, we produced our 12th update to the microPlatforms, roughly 1 update every 2 weeks. When we started the microPlatforms, we wanted to get our systems and processes running smooth enough to provide meaningful software updates that could be integrated into products by our subscribers. You may think that consuming software updates every 2 weeks is daunting, however, the upstream projects are ever-evolving and in this same period, Zephyr has seen 3,385 commits and the Linux Kernel has seen 28,876 commits and we aren’t even listing the changes of the other software projects. Long story short, with all this activity, there are new features and fixes that affect all aspects of computing that your products may have missed out on. With the microPlatforms we have created a product that not only keeps you close to the latest software, but standards-based and fully tested end-to-end for use within connected IoT products.

How To Manage LMP Containers

The Linux microPlatform uses a set of Docker containers to provide end-to-end services used by the Zephyr microPlatform. The containers and their configurations are deployed using a simple shell script that wraps Ansible. The scripts require a version of Ansible with Docker support. Some distro packages such as Ubuntu 16.04 don't have this, so make sure you install Ansible from a proper source before continuing.

Simplify your life: multi-architecture docker containers

> “The great thing about Docker is that your developers run the exact same container as what runs in production.” This is what the Docker hype is about, creating reproducible environments for applications. The technology enables us to create lightweight, secure microservices which run on an array of SoCs that can be updated over the air in a matter of seconds. We believe that accelerating code delivery will ultimately reduce time to market. Hype aside, Docker has matured and has become a foundational building block of our microPlatforms.
