A developer has successfully run Linux on the RISC-V cores of the Raspberry Pi Pico 2's RP2350 microcontroller, despite the challenges posed by its limited memory and lack of a memory management unit (MMU). The project required using a Linux version compatible with these constraints and additional memory from alternative boards like the SparkFun Pro Micro RP2350 or the Pimoroni Pico Plus 2 W. The installation process involves setting up a RISC-V build environment, cloning a GitHub repository, and compiling the necessary components. Although Linux can boot on the RP2350, its usability is currently restricted due to bugs, particularly with UART functionality, which only allows single-character input. This limitation hinders direct command entry in the shell. Despite these issues, the project serves as a proof of concept, indicating potential for future enhancements and applications in Raspberry Pi Pico projects.
