Michael Schröder sent us a link to his Gitlab repository
He managed to build RISC-V computer running Unix xv6 using only FOSS.
For hardware he choose our OSHW FPGA board iCE40HX8K-EVB

ESP32-C3-DevKit-Lipo is EUR 6.00 Open Source Hardware compact development board with:
- RISC-V running on 160Mhz
- 400KB RAM, 8K data RAM
- 4MB Flash
- Two headers (soldered) with power supply and GPIO signals
- ESP-PROG-C compatible rescue connector (if you mess with bootloader)
- USB-C for programming and JTAG debugging
- LiPo battery charger allowing handheld applications with single LiPo battery
- 4 mount holes
This is all you need to get started with RISC-V programming in C and Assembly.
Shteryana Shopova recently did RISC-V workshop with this board and explained how to setup your tools for programming and debugging. Here you can find her work.
Allwinner plans to release Linux capable RISC-V SOC this year

Searching for more info about their new H313 SOC I found old news from August 2020, where Allwinner announce the development of AP SOC with RISC-V and praising Open Source Hardware and the open ISA of RISC-V.
They say in this announcement that they will have AP (application processor) SOC with RISC-V in 2021!
There is lot of development around RISC-V in the last years. Espressif have their ESP32-C3 which is with RISC-V SOC, but it can’t run Linux as has not enough memory and video. We still can’t see affordable silicon capable to run Linux.
There is announcement for BeagleBoneV but still not in production and at quite higher price compared to ARM boards on the market.
Allwinner is known to be able to design and produce low cost SOCs. Let’s hope the semiconductor crisis caused by Covid19 will not delay their plans.
So is the year 2021 when we will see $35 Linux running boards with RISC-V?
I’m crossing fingers!
As soon as we can get our hands to these SOC we will make OSHW OLinuXino with it!
OSHW design and affordable SOC will lead to affordable boards and boost of the software development of RISC-V too.
