  • OTA for Embedded Linux Devices: A practical introduction

    A core belief of Memfault is that we can ship faster when we have good infrastructure in place. An essential piece of this infrastructure is tools to send firmware updates over the air. It enables the team to ship more often and spend more time building features.

    In this article, we look specifically at what is required to ship over-the-air firmware updates for Linux systems.

  • Saving bandwidth with delta firmware updates

    In this post, we introduce the concept of delta (i.e. partial) firmware updates, explain why you may want to implement them in your projects and go through an example implementation from top to bottom.

  • Device Firmware Update Cookbook
