FOSDEM 2025 will take place on February 1-2 with over 8000 developers meeting in Brussels to discuss open-source software & hardware projects. The free-to-attend (and participate) “Free and Open Source Software Developers’ European Meeting” grows every year, and in 2025 there will be 968 speakers, 930 events, and 74 tracks. Like every year since FOSDEM 2015 which had (only) 551 events, I’ll create a virtual schedule with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “RISC-V”, “FOSS Mobile Devices”, “Low-level AI Engineering and Hacking”, among others. FOSDEM 2025 Day 1 – Saturday 1 10:30 – 11:10 – RISC-V Hardware – Where are we? by Emil Renner Berthing I’ll talk about the current landscape of available RISC-V hardware powerful enough to run Linux and hopefully give a better overview of what to […]
Sonata v1.0 RISC-V platform combines AMD Artix-7 FPGA and Raspberry Pi RP2040 MCU, features CHERIoT technology for secure embedded systems
lowRISC has released Sonata v1.0, a stable platform developed under the Sunburst project. Designed for embedded systems engineers, Sonata supports CHERIoT technology, enabling features like compartmentalization and enhanced memory safety. It provides a reliable foundation for building secure embedded systems. CHERIoT is a security-focused technology built on lowRISC’s RISC-V Ibex core, based on CHERI research from the University of Cambridge and SRI International. It addresses memory safety issues like buffer overflows and use-after-free errors using CHERI’s capability-based architecture. The CHERIoT capability format includes permissions for memory access, object types for compartmentalization, and bounds to restrict accessible memory regions. These features enable scalable and efficient compartmentalization, making it suitable for securely running untrusted software in embedded systems. Sonata v1.0 leverages this architecture to isolate components like network stacks and kernels within the CHERIoT RTOS. The lowRISC Sonata v1.0 specifications: FPGA – AMD Xilinx Artix-7 (XC7A35T-1CSG324C) CPU – AMD MicroBlaze soft-core based on […]
SignalSDR Pro is a high-performance software-defined radio (SDR) in Raspberry Pi form factor (Crowdfunding)
The SignalSDR Pro is a Raspberry Pi-sized SDR that brings a credit-card-sized twist to software-defined radios (SDRs). It is a compact, streamlined device suitable for tasks ranging “from signal processing and spectrum analysis to communication systems and beyond.” The SignalSDR Pro builds on the Analog Devices AD9361 radio transceiver and the AMD Zync 7020 SoC into a credit-card format reminiscent of Raspberry Pi single-board computers. The Raspberry Pi-sized SDR also features a 40-pin GPIO header for expansion with other hardware components and added functionality. The device offers a 70MHz – 6GHz tuning range, 12-bit sample rate, 61.44MHz RF bandwidth, and two full-duplex TX/RX channels via four I-PEX antenna connectors. It is also capable of emulating other SDR hardware such as the ADALM-PLUTO and USRP B210, making it easier to integrate into pre-existing workflows. The SignalSDR Pro is a mid-range alternative to entry-level SDR options such as the AntSDR E200, KrakenSDR, […]
AMD Versal RF Series adaptive SoCs target 6G wireless, aerospace, and electronics test equipment
AMD Versal RF series adaptive system-on-chips (SoCs) combines Arm Cortex-A72 and Cortex-R5F hard cores with FPGA fabric and direct radio frequency (RF)-sampling data converters for pre-6G systems, wireless 6G testers, aerospace and defense applications like radars, and electronics test equipment such as multi-channel testers, oscilloscopes, and wideband spectrum analyzers. Built upon the Xilinx Zynq RFSoC devices, the AMD Versal RF Series supports wideband-spectrum with high-resolution thanks to up to sixteen 18 GHz, 14-bit RF ADCs with up to 32 GSPS and sixteen 14-bit RFV DACs up to 16 GSPS, and delivers 80 TOPS of DSP performance in a size, weight, and power (SWaP)-optimized design. The chips also integrate hard IP such as DDR5 memory controllers, 600 Gbps Ethernet, PCIe Gen5 x4, and various high-speed transceivers. AMD Versal RF Series adaptive SoCs key features and specifications: Processing System Application Processing Unit (APU) – Dual-core Arm Cortex-A72 with 48 KB/32 KB L1 […]

$20 ATOMIC Display Base is a low-cost HDMI display driver for M5Stack’s ESP32-based Atom IoT controllers
M5Stack has recently launched the M5Stack ATOMIC Display Base, an HDMI display driver designed to emulate traditional SPI TFT-LCD data output using Gowin GW1NR-9C FPGA and a built-in LT8618SX RGB-to-HDMI chip and designed to work with the company’s Atom IoT controller family based on ESP32 wireless microcontrollers. The module supports up to 720p (1280×720) image output with a 24-bit color depth and has an average frame rate of 12–16 FPS. Additionally, it can be paired with ATOM series hosts for various memory and application needs. These features make this compact device suitable for industrial control displays, smart home information screens, educational and conference presentations, and remote monitoring displays. The only downside of this device is that it requires a display with adaptive resolution scaling to avoid compatibility issues.

High-speed data acquisition with Raspberry Pi Pico 2’s HSTX interface and HDMI to USB 3.0 video capture dongle
We previously explained the HSTX high-speed serial transmit interface of the Raspberry Pi RP2350 microcontroller was mostly useful for video outputs and display interfaces since it can only transmit, and not receive data. But Steve Markgraf found another use case for the HSTX interface – high-speed data acquisition – combining a Raspberry Pi Pico 2 board with the DVI Sock board for Pico and one of those cheap MS2130-based HDMI to USB 3.0 video capture dongles. He managed to stream out up to 75 MB/s of real-time data from an overclocked RP2350 to a host computer with a USB 3.0 port. The Adafruit Feather RP2350 HSTX board should also work, but also not been tested. Steve’s “hsdaoh-rp2350” data acquisition over HDMI firmware is based on the dvi_out_hstx_encoder example from Raspberry Pi using the HSTX interface for DVI output and code by Shuichi Takano implementing the HDMI data island encoding required […]
