Groking the Linux SPI Subsystem - Matt Porter
The Serial Peripheral Interconnect (SPI) bus is a ubiquitous de facto standard found in many embedded systems produced today. The Linux kernel has long supported this bus via a comprehensive framework which supports both SPI master and slave devices. The session will explore the abstractions the framework provides to expose this hardware to both kernel and userspace clients. In addition, we will discuss subtle features of the SPI subsystem that may be used to satisfy hardware and performance requirements in an embedded Linux system.

Introducing Arm Mbed Linux OS | Mbed
It is with this backdrop that I was delighted to join Arm's Mbed team to solve these problems in a scalable and efficient way. My goal has been to extend the benefits of Mbed OS to IoT products that use Cortex-A silicon. We're delivering this "sibling" OS using the Linux kernel and with tools and recipes from the Yocto Project. This new OS will live alongside Mbed OS and is called the Mbed Linux OS. At a time when the price-performance ratio of Cortex-A SoCs continues to increase, it's possible to deploy ever more advanced processing within IoT devices. This can enable products to handle complex workloads more autonomously, improving availability and placing fewer demands on connectivity to the cloud or edge gateway. Mbed Linux OS is designed for these IoT devices and is deeply integrated with the Pelion IoT Platform to simplify lifecycle management. The mission of the Mbed Linux OS team is to provide and support the essential layers needed to build amazing IoT products, so OEMs are liberated to focus exclusively on adding their unique value. We want you to build products quickly and minimise the ongoing support and maintenance burden for products you’ve already shipped.

Amazon FreeRTOS - IoT operating system for microcontrollers - AWS
Amazon FreeRTOS (a:FreeRTOS) is an operating system for microcontrollers that makes small, low-power edge devices easy to program, deploy, secure, connect, and manage. Amazon FreeRTOS is based on the FreeRTOS kernel, a popular open source operating system for microcontrollers, and extends it with software libraries that make it easy to securely connect your small, low-power devices to AWS cloud services like AWS IoT Core or to more powerful edge devices running AWS Greengrass.
