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 […]

Hornet Nest Alarm Panel – An Home Assistant-compatible, ESP32 home security automation platform with PoE and 42-zone support (Crowdfunding)

Hornet Nest home security panel in operation

The Hornet Nest Alarm Panel is a customizable, ESP32-based alarm control system designed and produced by US-based Technology Automation Consulting for home security automation. The device is powered by the wESP32 Ethernet board with PoE support and is compatible with Home Assistant through the ESPHome firmware. It features up to forty-two optoisolated zones, six MOSFET-controlled outputs, and six additional trigger outputs for 3.3V devices. It integrates a piezo buzzer and supports add-ons like a Wiegand keypad and water leak sensors. The Hornet Nest Alarm ESP32-based home security platform “aims to bridge the gap between traditional wired security systems and the flexibility of modern smart home automation.” Christopher Greenless of Technology Automation Consulting says the project was born from his need for a robust and smart security system to integrate with his Home Assistant setup. Proprietary solutions were inadequate and limited while DIY options were inefficient and often unreliable. He created […]

u-blox MAYA-W4 tri-radio IoT module features NXP IW610 chipset with Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios

Last year, we covered the u-blox MAYA-W3 module, which was based on the Infineon AIROC CYW5551x chipset and utilized separate chipsets for 2.4 GHz, 5 GHz, and 6 GHz frequencies. Now, u-blox has introduced the MAYA-W4 series, a host-based Wi-Fi 6, Bluetooth 5.4, and 802.15.4 module built on the NXP IW610 chipset. Designed for industrial and commercial applications such as building automation, energy management, smart homes, and healthcare, the MAYA-W4 series supports SISO Wi-Fi 6 with a 20 MHz channel width, ensuring reliable performance in dense network environments. These modules can function as access points, stations, P2P devices, or in mixed modes. The MAYA-W4 modules are compatible with the Matter protocol over Thread and Wi-Fi, facilitating seamless integration across ecosystems. With a compact size of 10.4 x 14.3 mm, these modules rank among the smallest Wi-Fi 6 SMD modules and are available with integrated antennas or U.FL connectors. Rigorous testing […]

Mitigating a DoS attack with GoAccess and Cloudflare

In this off-topic post, I’m going to discuss some behind-the-scenes “fun” that may happen when managing the web server used to host the CNX Software website. From time to time, the server becomes unreachable, but I can still access its console, and notice a very high CPU load (over 100) on a VPS with four cores, while the CPU load is typically 0.5 to 2 under normal circumstances. That’s usually due to a DoS (denial of service), DDoS (distributed denial of service), or some bug I can’t identify. An easy way to solve this issue is to log in to Cloudflare and set the “Under Attack Mode” to on. It will show all visitors a JavaScript challenge the first time they visit the website, and the CPU usage typically drops back to normal level within a minute or so. That means I can access my website and so do regular […]

The first Android 16 developer preview is out (much) earlier than expected

Google releases a new Android version every year, and while the first Android 15 developer preview was released this year in February, the company has already announced the first Android 16 developer preview just a couple of months after the official release of Android 15 on AOSP in an “effort to drive faster innovation in apps and devices”. More specifically, Google plans to release two Android APIs next year: a major SDK release in Q2 2025 instead of Q3 followed by a minor SDK release in Q4 2025 that won’t include behavior changes that may require changes in apps, but only pick up feature updates, optimizations, and bug fixes. The change was mostly made to better accommodate the device launch schedule of smartphone manufacturers. That almost means many more changes are expected between the preview and the beta release. As of now, Google has only announced a few new features […]
