Show HN: OpenC6 v2.0 – Bare-metal BIOS and RISC-V microkernel for ESP32-C6

Category: infrastructure

Tags: risc-v, microkernel, embedded, esp32, bios, firmware

Score: 6.5/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 4)

OpenC6 is a bare-metal BIOS and microkernel for the ESP32-C6 RISC-V microcontroller, bringing PC-style architecture with hardware memory protection, a process manager, and a shell to microcontrollers. It decouples hardware initialization from user-space execution, allowing dynamic loading of unprivileged payloads and featuring innovative systems like an out-of-band supervisor on the low-power core.

Target audience: embedded developers, firmware engineers, RISC-V enthusiasts
