I attended the 36th Chaos Communication Congress (36c3) during the last
week of 2019 in Leipzig, Germany. It was an amazing event and Hackaday has good coverage. All the talks are available online including my talk:
Linux on Open Source Hardware with Open Source chip design
Want to run Linux on open hardware? This talk will explore Open Source Hardware projects capable of that task, and explore how RISC-V and free software FPGA projects can be leveraged to create libre systems.
The video is also available on YouTube:
My slides are on SlideShare:
The slides are also available as a PDF on GitHub.
Joining Adafruit Show ‘n Tell with Helen Leigh was a fun way to start 2020!
Helen embroidered the CircuitPython-powered Serpente board from Arturo at Chaos Communication Congress (36c3):
I showed Linux running on a RISC-V core in the ECP5 FPGA on the Hackaday Supercon badge:
I gave a shout-out to Greg Davill who got Linux booting the OrangeCrab while at 36c3:
Greg’s open hardware OrangeCrab board features the ECP5 FPGA in an Adafruit Feather form factor and is capable of running a RISC-V “soft” core using LiteX.

Early this year, the world of electronics saw something amazing. The RISC-V, the first Open Source microcontroller was implemented in silicon, and we got an Arduino-derived dev board in the form of the HiFive 1. The HiFive 1 is just a bit shy of mindblowing; it’s a very fast microcontroller that’s right up there with…
via A Smaller, Cheaper RISC V Board — Hackaday
LoFive RISC-V dev board designed by Michael Welling with KiCad is now on GroupGets:
LoFive is a small board based on the SiFive Freedom E310 open source SoC
- MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz)
- Storage – 128-Mbit SPI flash (ISSI IS25LP128)
- Expansion – 2x 14-pin headers with JTAG, GPIO, PWM, SPI, UART, 5V, 3.3V and GND
- Misc – 1x reset button, 16 MHz crystal
- Power Supply – 5V via pin 1 on header; Operating Voltage: 3.3 V and 1.8 V
- Dimensions – 38 x 18 mm (estimated)
- License – CERN Open Hardware Licence v1.2
The design files are available on GitHub:
Here is the LoFive compared compared to the Teensy 3.2:

mwelling has shared the board on OSH Park:
The Free and Open Source Silicon (FOSSi) Foundation fosters open source semiconductor design and we’re proud to have become a sponsor! Julius Baxter writes on the FOSSi Foundation blog:
We are pleased to announce that OSH Park, the purveyors of perfect purple PCBs, have become sponsors of the FOSSi Foundation’s activities. We are very grateful for their support and would like to recognize this by listing them on our Sponsors page at the Bronze tier.
We are actively looking for sponsors for the Foundation, if you’re interested in learning more about our activities and why we are looking for sponsorship, then please visit our sponsorship page and for more, see our detailed sponsorship proposal document.
More information on the FOSSi Foundation:
Inspired by the success of open source software, the Foundation will help bring about IP and tools of comparable quality to proprietary offerings, and which are developed according to an open source model by a highly collaborative and inclusive community. The FOSSi Foundation will address the issues the field currently faces; fragmentation, legal uncertainty, design quality, and high barriers to entry.
FOSSi has launched LibreCores:
gateway to free and open source digital designs and other components that you can use and re-use in your digital designs.
FOSSi also organizes the ORConf:
