HardROCK64 specifications: SoC –  Rockchip RK3399 hexa-core processor with 2x Arm Cortex-A72 @ up to 1.8 GHz, 4x Cortex-A53 @ up to 1.4 GHz, a Mali-T864 GPU, and a VPU with 4K VP9 and 4K 10-bit H265/H264 decoding System Memory – 1GB, 2GB or 4GB LPDDR4 Storage – SPI flash, eMMC flash socket, MicroSD card slot Video Output – HDMI 2.0, AV port, MIPI DSI connector Audio – Analog stereo audio via AV port, digital audio via HDMI Camera – MIPI CSI connector Connectivity – Gigabit Ethernet, dual-band WiFi 5 (802.11ac) and Bluetooth 5.0 USB – 2x USB 3.0 ports, 2x USB 2.0 ports Expansion – 40-pin Raspberry Pi compatible header […]

Some Interesting Talks from FOSDEM 2020 Schedule

FOSDEM 2020 Schedule

We wrote about IoT devroom call for proposals for FOSDEM 2020 a little while ago, and as the free open-source developer meetup is getting closer, FOSDEM 2020 organizers released the schedule. So I’ll look at some of the talks in the relevant devrooms such as the Internet of Things, hardware enablement, Embedded, Mobile and Automotive, as well as RISC-V and others to compose my own little virtual schedule for the 2-day event. Saturday, February 1 10:30 – 10:50 – How lowRISC made its Ibex RISC-V CPU core faster – Using open source tools to improve an open-source core – by Greg Chadwick Ibex implements RISC-V 32-bit I/E MC M-Mode, U-Mode, and PMP. It uses an in-order 2 stage pipe and is best suited for area and power-sensitive rather than high-performance applications. However, there is scope for meaningful performance gains without major impact to power or area. This talk describes work […]

OpenWiFi Open-Source Linux-compatible WiFi Stack Runs on FPGA Hardware


WiFi is omnipresent on most connected hardware, and when it works it’s great, but when there are issues oftentimes they can not be solved because the firmware is a closed-source binary. I understand companies do that either to protect their IP and/or make sure end-users do not break FCC compliance. OpenWiFi project aims to deliver a completely open-source SDR (Software Defined Radio) WiFi implementation compatible with Linux and running on FPGA hardware. OpenWiFi currently supported features: 802.11a/g; 802.11n MCS 0~7; 20MHz Mode tested: Ad-hoc; Station; AP DCF (CSMA/CA) low MAC layer in FPGA Configurable channel access priority parameters: duration of RTS/CTS, CTS-to-self SIFS/DIFS/xIFS/slot-time/CW/etc Time slicing based on MAC address Easy to change bandwidth and frequency: 2MHz for 802.11ah in sub-GHz 10MHz for 802.11p/vehicle in 5.9GHz The developers tested OpenWiFi on Xilinx ZC706 FPGA evaluation kit coupled Analog Devices fmcomms2/fmcomms4 RF board to form an access point, and connected it to […]

FOSDEM 2020 IoT Devroom Call for Proposals

FOSDEM 2020 IoT Devroom

FOSDEM (Free & Open-source Software Developers’ European Meeting) takes place every year in Brussels, Belgium on the first weekend of February.  FOSDEM 2020 is scheduled for February 1-2, and now that developer rooms have already been announced, there are calls for proposals for each topic. Benjamin Henrion (aka Zoobab), a frequent reader and commenter of CNX Software, will be in charge of the IoT devroom and has now initiated a call for proposals for Internet of Things talks. The devroom will take place on Saturday or Sunday between around 10.30 and 18:00. Each talk will last 25 minutes with a 5-minute break between talks. The talks must be about fully open source projects that cover one of the topics below: Machine-to-machine (M2M) communication on small embedded devices Distributed applications in any field of interest for autonomous/self-controlled devices, (e.g. domotics, automotive, etc) Networking: TCP/IP, mesh networking, message queuing, cross-layer solutions Real-life […]
