Running UNIX on Raspberry Pi Pico: A $5 Microcontroller's UNIX Journey

Tech enthusiasts successfully ran the Fuzix operating system, a lightweight version of UNIX, on the Raspberry Pi Pico microcontroller. The article details the entire process from environment setup and system compilation to installation and usage. The author created a compilation environment using Docker, modified the source code to adapt to the Pico hardware, and experienced this UNIX-like system through a serial connection. The system includes 122 basic command tools, supports GPIO operations and script execution, demonstrating the possibility of running traditional operating systems on low-cost hardware. This practice not only showcases technical depth but also provides new insights for embedded system development.
