349: Open Down to the Transistor
1 hr 14 min

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:

Here are some future conferences he’s planning to attend:

Moore's Lobby: Where engineers talk all about circuits
Moore's Lobby: Where engineers talk all about circuits
All About Circuits
Ep. 13 | How Motorsports Are Accelerating Product Development for Next-Gen Automotive Applications
In this keynote, Lucas and Bryn will engage in discussion with Dave Finch, engineer, New York Times bestselling author, and producer of the Moore's Lobby podcast on All About Circuits. The keynote session will be followed by a live Q&A with the audience.   About Lucas di Grassi Born in Sao Paulo, Lucas di Grassi is one of developers of the highly successful, electric-powered Formula E. Lucas also is a member of the board and developer of Roborace, the racing series for electric cars run by artificial intelligence which is set to become the most efficient developing environment for connected AI-based technology. Recently, Lucas was announced as partner and ambassador for the Electric Scooter Championship (eSC), a new international series aimed to promote both competition and technology development for urban micro-mobility. Di Grassi drew international attention when he drove a Formula E car on the North Pole ice cap to set an alert to global warming. In May 2018, Lucas was appointed ambassador for the United Nations Environment Program with the mission to increase awareness about poor urban air quality, which causes over 6 million premature deaths around the world. Lucas is the most relevant driver of the FIA Formula E history having amassed the impressive sequence of three thirds and a second championship season places, plus the 2017 world title. Having previously competed in Formula One, di Grassi is again a title contender of FIA World Formula E Championship for the official Audi Sport Abt Schaeffler team.   About Bryn Balcombe Bryn Balcombe is the Chief Strategy Officer for Roborace. He received his BEng in Mechanical Engineering and Vehicle Design from the University of Hertfordshire. Balcombe previously spent 16 years working with Formula One racing, architecting communication systems for vehicle-to-infrastructure connectivity, as well as implementing the Formula One Global Media Network. He has experience on projects ranging from circuit development to full tracking systems and automated vehicles. Balcombe is the founder of ADA.ngo, a non-profit alliance developed to ensure the safe and ethical deployment of human-centric artificial intelligence in automotive applications to prevent road traffic injuries. ADA.ngo supports the use of motorsports as a means of accelerated R&D for automotive AI. He additionally serves as the Chair of ITU Focus Group on AI for Autonomous and Assisted Driving for the International Telecommunication Union (ITU FG-AI4AD), where this focus group serves as a forum for international organizations such as governments and research institutions can collaborate to evaluate AI-assisted and automated vehicle safety.
