Developed the foundational integration of LittleFS-based persistent storage for Pico MRAM within the scsd-cdh/OBC repository, focusing on embedded systems and file system reliability. The work involved integrating the core LittleFS library, configuring SPI communication, and establishing MRAM setup alongside mounting and formatting logic. To streamline development, a temporary cleanup disabled LittleFS initialization, enabling faster iteration and debugging. Test code was implemented to verify SPI operation on the Pico platform, supporting ongoing LittleFS development and future persistence features. The project utilized C and C++ programming, emphasizing microcontroller interfacing and robust storage groundwork to support future enhancements and maintainability.
