Getting Linux To Run On Your Custom Board
The ability of silicon vendors to pack more components and capability into a single silicon die has allowed these System On Chips (SoCs) to support Linux. In turn, developers have been able to quickly migrate their application to be deployed "to the edge" without significant rework. The main objective of this session is to provide embedded systems engineers an overview on the steps necessary to get Linux running on a custom board, issues they may face, and how to debug these issues. This session will provide an introduction to Linux and its value in embedded systems, and how it differs from "traditional" Linux that runs on desktops. This session will also discuss how Linux differs from other embedded software paradigms, such as "bare-metal" and RTOS-based application development.
Hawkbit and SWUpdate for OTA Updates of Linux IoT Devices
Linux-based IoT devices don't have a flat Flash structure that allows for a straightforward OTA update process. There are a multitude of bootloader, kernel, and root file system combinations that must be taken into consideration, along with the different failure modes. The combination of Hawkbit and SWUpdate aim to standardize the OTA update process for IoT devices running Linux. This session will provide an overview of Hawkbit and SWUpdate, the different components that can be updated, and the different failure modes that are supported. A case study will be presented to demonstrate how to set up Hawkbit and SWUpdate to support OTA updates for a Linux-based IoT device. Finally, ongoing work by the presenter to address current shortcomings will be discussed.
