Special Guest: Tim Canham.

On this episode, the Insiders discuss safety-critical open source operating systems. Do the rigid requirements of safety-critical embedded applications force users to reduce the flexibility many believe is the biggest advantage of open source? And if so, why not just license a commercial offering?Next, Kate Stewart, Vice President of Dependable Embedded Systems at the Linux Foundation, provides her take on the evolution of embedded operating systems, from RTOSs to Linux. And what does that mean for systems engineering today?Finally, Embedded Computing Design's Assistant Editor Taryn Engmark, gives us the rundown on BrakTooth, a group of security vulnerabilities in more than 1,400 Bluetooth-enabled devices, and what you can do about them.

This is Low Code Legends: quick hits with top people in low and no code. Today: Oleg Oksyuk. While working in startups on the engineering side I created cool things like Adobe Flash Player for Embedded Linux and MPEG/H264 Video Streaming with Fast Forward and Rewind without bitrate increase (according to Apple engineers that was impossible). Then I started to found startups and switched to the business side with many ideas that failed after fast trials of 2-6 months (including Ethereal Lite - Create art with your bare fingers in the air) and modest success in LiveExpert (an expert advice marketplace). I've been working on AllRight, an online English School for kids for the last 4 years, where I've built the team to 80 people ... not counting 700 teachers.

In this episode, we discuss Embedded Linux application development.

Jay Carlson joins Chris to talk about his recently released opus on building embedded Linux for microprocessors and the process of building 10 different boards to showcase the required steps.

Drew Fustini (@pdp7) spoke with us about building Linux, RISC-V cores, and many other things. Links, so many links! Drew is a board member of the BeagleBoard.org Foundation and of the Open Source Hardware Association (OSHWA.org). He is an open source hardware designer at OSHPark (he recommends their blog!). He writes a monthly column for Hackspace Magazine, for example The Rise of the FPGA in Issue 26 and  Intro to RISC-V.  Yocto is a tool to help build a Linux distribution specific to your board and application! Bootlin offers free training material for Yocto and OpenEmbedded (as well as many other things such as Embedded Linux and Linux kernel development). Or there is a video: Buildroot vs Yocto: Differences for Your Daily Job - Luca Ceresoli at Embedded Linux Conference. Or look at Embedded Apprentice Linux Engineer (e-ale.org). Or maybe another video: “Yocto Project Dev Day Virtual 2020 #3: Yocto Project Kernel Lab, Hands-On, Part 1” by Trevor Woerner. RISC-V is an open source processor core. Well, cores. But you can try them out in hardware even if you don’t want to play with an FPGA. The SiSpeed Longan Nano has a GigaDevices microcontroller dev board (with an OLED on board!, more info). Did you know you can run Linux on RISC-V? The cheapest method is emulation and Renode is brilliant for that. Here is Drew using it on the train (twitter). Sipeed boards with Kendryte K210 start at only $13 and can even run Linux (tutorial). There are also affordable open hardware FPGA with free software toolchain support like the ICE40 based Icebreaker and Fomu. For a bit more money, the bigger ECP5 can run Linux. Or look at Greg Davill’s wonderful Orange Crab. For a lot more money but on silicon, the Icicle with Microchip PolarFire SoC is aimed at corporate use. Or you can produce your own physical chips. For free (for a limited time). See the talk from Tim Ansell - Skywater PDK: Fully open source manufacturable PDK for a 130nm process Drew attends a lot of conferences, here are highlights from the past: OHS 2020 wrist badge  OHS 2018 epaper badge  ELC-2018 EALE Buildroot - Thomas Petazzoni  ELC-2018 EALE Bitbake YP - Behan Webster Linux on RISC-V with open hardware and open FPGA tools Sldies for Embedded Linux Conference Video from FOSS North Linaro Connect BoF: gpio and pinctrl in Linux kernel (Slides) RISC-V: How an open ISA benefits hardware security (Slides) (Hardwear.io video)   Here are some future conferences he’s planning to attend: Embedded Linux Conference Europe ($50) October 26-29, 2020 (Virtual) Yocto Project Virtual Summit ($40) October 29-30, 2020 (Virtual) Open Hardware Summit March 13, 2020

This week on the Embedded Insiders, Brandon and Rich discuss an age-old controversy: What’s more secure? Proprietary or open-source software?That discussion leads into an interview with Kate Stewart, Senior Director of Strategic Programs at the Linux Foundation, who joins the program to explain how the Zephyr Project responded to 25 vulnerabilities recently uncovered in its open-source code base by the NCC Group, an independent security analysis firm. After reassuring the Insiders by detailing the steps taken to remedy those bugs and explaining the security practices in place at the Zephyr Project, Stewart continues to introduce the Embedded Linux in Safety Applications, or ELISA, project, which seeks to better align Linux software and tools with the requirements of safety-critical industries. Where does ELISA fit in with other projects like RTLinux, and how can the software test community help accelerate the expansion of Linux into platforms ranging from road vehicles to rockets?For more information on the Zephyr vulnerabilities, read “Another IoT Security "Uh-Oh": 26 Flaws in Open-Source Zephyr and MCUboot Stacks” on www.embedded-computing.com.To learn more about the ELISA Project and updates to the Zephyr Project, attend one of Kate Stewarts presentations during the Linux Foundation’s Open Source Summit North America, a virtual event taking place from June 29th to July 2nd.
