SCINTIX P4 ESP32-P4 Compute Module works with (some) Raspberry Pi CM4/CM5 carrier boards (Crowdfunding)

SCINTIX P4 is an ESP32-P4 RISC-V Compute Module with an ESP32-C6 for wireless connectivity that's compatible with Raspberry Pi CM4/CM5 carrier boards, at least partially. It should be the first MCU-based system-on-module in Raspberry Pi CM4/CM5 form factor, and RELOC says the SCINTIX P4 gives access to displays, cameras, Ethernet, USB, and all the peripherals the ESP32-P4 exposes when connected to a carrier board. It can also be programmed in standalone mode through its built-in USB Type-C port. SCINTIX P4 (RM-CMP4) specifications: SoC - Espressif Systems ESP32-P4NRW32X  CPU Dual-core RISC-V @ 400 MHz with AI instruction extensions and single-precision FPU Single-core RISC-V LP (low-power) MCU @ 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 - 128 KB HP ROM, 16 KB LP ROM Storage

🌘 Rust 與 C/C++ 在記憶體安全 CVE（常見漏洞與披露）上的差異解析
➤ 為什麼 Rust 的 CVE 比 C/C++ 看起來更「嚴苛」？
✤ https://kobzol.github.io/rust/2026/06/15/how-memory-safety-cves-differ-between-rust-and-c-cpp.html
本文探討了 Rust 與 C/C++ 在處理記憶體安全漏洞時的根本差異。作者指出，由於 C 與 C++ 語言本身的特性，許多因「使用不當」導致的記憶體錯誤（如傳入 NULL 指標）通常不被視為漏洞，僅被視為呼叫端的使用錯誤；反之，在 Rust 中，任何能透過「安全代碼（Safe Rust）」觸發記憶體錯誤的 API，都會被定義為該函式庫的「健全性漏洞（Soundness Bug）」。因此，Rust 的 CVE 標準遠比 C/C++ 嚴格，這也解釋了為何在比較兩者漏洞數量時，必須考量其背後截然不同的安全責任歸屬。
+ 這篇文章很好地釐清了為什麼 Rust 生態系對「安全性」的要求

How memory safety CVEs differ between Rust and C/C++

CVE is a database used for categorizing and reporting security vulnerabilities in software. There are various kinds of vulnerabilities that can be reported. Some of them are caused simply by bugs in the program logic (like a recent CVE reported in Cargo), but some of the most nasty ones are caused by memory unsafety, which can easily lead to exploits. In this post I want to focus on the latter kind of CVEs, how they are reported, especially in libraries, and how it differs between Rust and C or C++.

Fortior FU75xx dual-core motor control MCU family combines 32-bit RISC-V core with 2nd-gen Motor Engine (ME2) core

Motor driver IC specialist Fortior Technology has recently introduced the FU75xx dual-core motor control MCU family, pairing a 32-bit RISC-V core and the company’s proprietary 2nd-generation Motor Engine (ME2) core. The RISC-V core is used for parameter configuration and routine processing, while the ME core integrates FOC and CORDIC modules that enable fast calculation of FOC (as quick as 5µs)  or square-wave control for sensored/sensorless BLDC/PMSM motors. The chips have an impressive list of peripherals (see specs below) and target high-speed computing and real-time control for robotics and motion systems, such as industrial servo drives, robotic joints, smart home appliances, and new energy vehicle systems. FU75xx MCU specifications: Dual-core CPU RISC-V core @ 48 MHz ME2 motor engine core @ 48 MHz with FOC module and CORDIC module Memory - 12kB SRAM, 4kB PRAM for program execution Storage - 64kB Flash with ECC and CRC, self-program and code protection I/Os

Bare-metal MSX2+ Emulator for ESP32-S3 offers custom LCD_CAM VGA implementation & Z80 optimizations

https://fed.brid.gy/r/https://www.cnx-software.com/2026/06/11/bare-metal-msx2-emulator-for-esp32-s3-offers-custom-lcd_cam-vga-implementation-z80-optimizations/

Bare-metal MSX2+ Emulator for ESP32-S3 offers custom LCD_CAM VGA implementation & Z80 optimizations

Ivan Svarkovsky's S3-MSX-PC open-source project implements a bare-metal MSX2+ emulator running on an ESP32-S3 microcontroller and outputting 64-color VGA via a simple R-2R resistor ladder. It's a fork of the Retro-Go emulator for ODROID-GO and other ESP32 devices, but with various optimizations. It was tested on an off-the-shelf ESP32-S3 board with one core handling the game logic and the other video and audio output. VGA is implemented through a clever resistor network that converts digital data into an analog signal that any old monitor understands, while audio relies on Sigma-Delta modulation with a multi-stage PDM filter. The USB host port on the board allows for the connection of a keyboard. S3-MSX-PC firmware highlights: Emulation Core - fMSX 6.0 — Full MSX1 / MSX2 / MSX2+ support Video Output VGA 640×480@60Hz, 16-bit parallel RGB via LCD_CAM Color Depth - 64 colors (2 bits per channel: R, G, B) Audio - PDM Stereo

OpenCV 5 release – New DNN engine with enhanced ONNX and LLM/VLM support, Intel, Arm, and RISC-V hardware optimizations

https://fed.brid.gy/r/https://www.cnx-software.com/2026/06/10/opencv-5-release-new-dnn-engine-with-enhanced-onnx-and-llm-vlm-support-intel-arm-and-risc-v-hardware-optimizations/

OpenCV 5 release – New DNN engine with enhanced ONNX and LLM/VLM support, Intel, Arm, and RISC-V hardware optimizations

OpenCV 5 open-source computer vision library has recently been released with a brand-new DNN (Deep Neural Network) engine that provides better ONNX coverage and enables LLM/VLM support. The fifth version of the popular CV library also adds support for Intel, Arm, Qualcomm, and RISC-V hardware acceleration, improved 3D vision, and various new core features such as new data types, real N-dimensional and scalar support, and performance improvements. OpenCV 5's DNN Engine OpenCV 4.x supports about 22% of ONNX operators, and the new DNN engine in OpenCV 5 brings coverage to over 80%.  That means models with dynamic shapes that used to fail on OpenCV 4.x, should now work, as the 5.x engine was rebuilt around a typed operation graph with proper shape inference, constant folding, and operator fusion. The table below shows the main difference between OpenCV 4.x and OpenCV 5 Since it's quite a big change, to make sure
