Intel releases SDK for Cortex-M7 PSE found in Elkhart Lake processors

Elkhart Lake processors integrate the Intel Programmable Services Engine (Intel PSE) offload engine for IoT workloads powered by an Arm Cortex-M7 microcontroller that handles real-time IO control using GPIO, I2C, and/or UART interfaces, and supports functions such as remote, out-of-band device management, network proxy, embedded controller, and sensor hub. Until now the firmware was only provided as a closed-source binary, and Coreboot developers published an open letter to open the source code for the PSE firmware last December, and it’s been successful with Intel releasing the Intel PSE SDK based on Zephyr OS. The SDK combines open-source components (code samples, services, etc…) released under a permissive Apache 2.0 license (“License A”), and closed-source libraries and tools released under an Intel license (“License B”) allowing the redistribution and use in binary form, without modification. You’ll find everything on Github including documentation explaining how to get started with the Zephyr SDK, the […]

The Eclipse Oniro Project aims to deliver consumer & IoT software that works across multiple platforms

Several of the embedded talks at FOSDEM 2022 mention the “Eclipse Oniro Project”. I had never heard about that project from the Eclipse Foundation, so let’s see how they describe it: Oniro is an Eclipse Foundation project focused on the development of a distributed open source operating system for consumer devices, regardless of the brand, model, make. Oniro is a compatible implementation for the global market of OpenHarmony, an open source operating system specified and hosted by the OpenAtom Foundation. Designed with modularity in mind, Oniro offers greater levels of flexibility and application portability across the broad spectrum of consumer and IoT devices — from tiny embedded sensors and actuators, to feature rich smart appliances and mobile companions. As a distributed and reusable collection of open source building blocks, Oniro enables compatibility with other open source technologies and ecosystems. Through close collaboration with projects and foundations such as OpenHarmony from […]

FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others. Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so. First and foremost, […]

Status of Zephyr and NuttX RTOS support for ESP32

Espressif has recently announced that both Zephyr and NuttX open-source real-time operating systems had gotten official support for the ESP32 series of WiSoCs. It’s been a long time in the making, and when I first tried the community developer port of Zephyr OS on ESP32 in 2018 it did not work well at all, and I could not even make the blink LED sample work on Wemos Lolin32 board, and the WiFi sample would not even build. But time has passed, Espressif Systems started to officially work on Zephyr in 2020, and now I/Os, WiFi, and some other features work on Zephyr and NuttX RTOSes. Zephyr on ESP32 We first wrote about the Zephyr Project in 2016 describing the OS as follows: Zephyr Project is a lightweight real-time operating system (RTOS) designed for IoT applications and comprised of a microkernel for lower priority tasks, as well as a nanokernel to […]

Coin cell-powered OpenThread sensor board can send data every 20 seconds for three years

Monkey Store’s Thread Sensor Tag is a pressure, humidity, temperature, and light sensor that connects to the OpenThread network, and is capable of transmitting MQTT/UDP data every 20 seconds over a period of around three years from a single coin cell battery. As a reminder, OpenThread is an implementation of the Thread IoT network protocol that was unveiled in 2016 by Nest Labs (now Google/Alphabet). This has not been widely used so far, but we did write about MKR SharkyPro development board with OpenThread support via STMicro STM32WB5MMG wireless module earlier this year, and Monkey Store is telling us both Google and Apple are working on devices with support for the IoT protocol. Thread Sensor Tag specifications: Wireless module – Minew MS88SF2 based on Nordic Semi nRF52840 multi-protocol 2.4GHz wireless Cortex-M4 microcontroller Sensor VEMLS6030 I2C light sensor MS8607 pressure, humidity, and temperature sensor I/Os – 7x through holes with Tx/Rx, […]
