Ubuntu 25.10 release to mandate RVA23 profile, obsoleting most RISC-V hardware

Orange Pi RV2 No Ubuntu 25.10 26.04

RISC-V is an open architecture standard that provides flexibility, and chip designers can add or remove instructions as they please to match their application requirements. That’s all great until complex software designed to run on multiple platforms is involved. That’s why for Linux and Android support, the RVA (RISC-V Application) profiles were created, so that every RISC-V SoC designed for those systems meets some minimal requirements and shared instructions, to which you would also add more if needed, as long as they don’t break the standard. The RISC-V association ratified the latest RVA23 profile for 64-bit RISC-V in October 2024, which notably mandates support for the vector and hypervisor extensions. OMGUbuntu also reports that Canonical has decided to raise the required RISC-V ISA profile family to RVA23, or more exactly RVA23U64, from RVA20 for the upcoming Ubuntu 25.10 release. In other words, going forward, Ubuntu will only be supported on […]

$3.50 nanoCH57x CH570/CH572 RISC-V development board offers USB-C port, 2.4GHz radio/BLE, and GPIO pins

MuseLab nanoCH57x development board

Designed by MuseLab, the nanoCH57x is a WCH CH570/CH572 development board with a 2.4 GHz proprietary radio (CH570) or Bluetooth LE (CH572) that only costs $3.50 and is more compact than the official CH570 Basic Evaluation Board. We first came across this low-cost MCU back in March this year, and saw that the official development board became available for purchase as early as April. The nanoCH57x development board currently features the 100 MHz  CH572D RISC-V microcontroller (the CH570D version is coming later), which includes 256KB of flash memory, 12KB of SRAM, and an onboard 32 MHz crystal. The board also includes a USB 2.0 Type-C Host/Device port and PCB antenna for BLE/RF communication. MuseLab nanoCH57x development board specifications: MCU (one or the other) – WCH CH570D or CH572D CPU – QingKe 32-bit RISC-V3C core @ up to 100 MHz Memory – 12KB SRAM Storage – 256KB non-volatile memory 240KB code […]

ALIENTEK DNESP32P4M – An ESP32-P4 board without network connectivity

ESP32P4M MINI board

Most ESP32-P4 boards and development platforms we’ve covered so far include an ESP32-C6 or ESP32-C5 wireless module, and in case you don’t want any WiFi and Bluetooth module, the Olimex ESP32-P4-DevKit is one option that comes with Ethernet instead. The ALIENTEK DNESP32P4M board, also called ESP32P4M MINI, adds another option with a form factor similar to Espressif Systems Devkit-C boards. The board does not have network connectivity at all, and exposes all I/Os from the ESP32-P4 through headers, MIPI DSI and MIPI CSI connectors, and two USB-C ports. ALIENTEK DNESP32P4M specifications: Microcontroller – ESP32-P4 (ESP32-P4NRW32) MCU Dual-core RISC-V microcontroller @ 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz GPU – 2D Pixel Processing Accelerator (PPA) VPU – H.264 and JPEG codecs support Memory – 768 KB HP L2MEM, 32 KB LP SRAM, 8 KB TCM, 32MB PSRAM Storage – […]

XIAO Vision AI Camera combines ESP32-C3 and WiseEye2 HX6538 AI MCU with 5MP camera, supports SenseCraft no-code platform

Seeed Studio XIAO Vision AI Camera

Seeed Studio has recently released the XIAO Vision AI Camera, a compact, open-source smart ESP32-C3 AI Camera that integrates the Grove Vision AI Module V2, a XIAO ESP32C3 module, and an OV5647 5MP camera in a custom 3D-printed PLA case. One of the key components of the camera module is the WiseEye2 HX6538 chip, which features dual-core Arm Cortex-M55 processors and an Ethos-U55 NPU for edge AI computing. It also comes with Wi-Fi connectivity, turning it into an intelligent IP camera that easily integrates with Home Assistant for closed-loop automation (e.g., object detection triggering lights or alerts). Its 5MP OV5647 camera can record 1080p@30fps video and has adjustable focus. These features make this camera useful for industrial automation, smart cities, transportation monitoring, intelligent agriculture, and mobile IoT devices.

Linux 6.15 Release – Main changes, Arm, RISC-V and MIPS architectures

Linux 6.15 release

Linus Torvalds has just announced the release of Linux 6.15: So this was delayed by a couple of hours because of a last-minute bug report resulting in one new feature being disabled at the eleventh hour, but 6.15 is out there now. Apart from that final scramble, things looked pretty normal last week. Various random small fixes all over, with drivers as usual accounting for most of it. But we’ve got some bcachefs fixes, some core networking, and some mm fixes in there too. Nothing looks particularly scary. And this obviously means that the merge window opens tomorrow as usual, and I see the usual people being proactive and having sent me their pull requests. It’s memorial day tomorrow here in the US, but like the USPS, “neither snow nor rain nor heat nor gloom of night” – nor memorial day – stops the merge window. [ Actually, thinking back […]
