OpenC6 BIOS brings PC-like architecture to ESP32-C6

Rompass built OpenC6, an open-source BIOS for the ESP32-C6 chip that enables a PC-like architecture on the $2 microcontroller. The firmware initializes hardware, provides out-of-band management via an LP-Core coprocessor, and hosts bare-metal payloads that can be hot-swapped into RAM or XIP. The project remains incomplete, with missing features including an open file system and execution security.
