A BIOS For Your ESP32-C6

Rompass đã phát triển một firmware tương tự BIOS cho vi điều khiển ESP32-C6, cung cấp bootloader và lớp API hỗ trợ tải động các chương trình từ RAM, thậm chí qua mạng. Dự án thể hiện xu hướng xóa nhòa ranh giới giữa vi điều khiển và bộ vi xử lý, xu hướng này sẽ tiếp tục khi các bộ xử lý ứng dụng mạnh mẽ như ESP32-P4 trở nên phổ biến.

Lập trình viên ESP32-C6 nên đọc để khám phá cách mở rộng khả năng quản lý khởi động và chạy ứng dụng động từ RAM hoặc mạng, giúp tối ưu hóa hiệu suất và linh hoạt cho các dự án yêu cầu tính linh hoạt cao hơn.

OpenC6 BIOS project brings PC-like firmware to ESP32-C6 MCU with network boot and OTA update support

OpenC6 BIOS is an open-source project that brings PC BIOS-like architecture to the ESP32-C6 microcontroller. Instead of combining hardware setup and application code into a single firmware image, it separates the base system from application payloads (2–10 KB). Key features include dynamic CPU frequency scaling, a System Call Interface (ABI) for Wi-Fi/crypto/math access without full ESP-IDF, PXE-like network boot over Wi-Fi, A/B OTA updates with rollback, a web-based BIOS setup interface, LP-Core health monitoring using the ESP32-C6's low-power RISC-V core, and Aura Sync RGB support. The project targets ESP32-C6 boards with at least 8MB flash and is available on GitHub under the MIT license.

Someone built a BIOS for the ESP32-C6, bringing a PC-like architecture to the $2 chip

OpenC6 is an open-source BIOS-like firmware for the ESP32-C6 microcontroller that reimagines the $2 chip with a PC-style architecture. Rather than monolithic firmware, it acts as a host platform that initializes hardware, provides out-of-band management via an LP-Core coprocessor, and exposes a standardized System Call Interface (ABI). This lets developers hot-swap, download, and execute tiny bare-metal payloads directly into RAM or Execute-In-Place (XIP) Flash. The project is still in progress, with open bounties for features like a fully open-source file system and execution security measures.

Fwupd 2.0.21 Brings Fixes For More Than 250 Potential Security Issues Found Via AI

Fwupd 2.0.21 has been released as a backport release for the 2.0.x stable series, incorporating fixes for over 250 potential security issues discovered using AI security scanners including Anthropic's Mythos over the past three months. The release targets conservative Linux distributions that don't adopt new feature releases in their stable archives. Users on the 2.1.x series already have these fixes plus additional hardening work.
