During November 2024, Mihir Vari worked on the CURocketEngineering/Avionics repository, focusing on enhancing the FlashDriver component within the avionics firmware. He implemented robust control mechanisms and new command support to improve flash memory write, erase, and read operations, addressing reliability and data integrity concerns. His approach included optimizing SPI communication, managing status registers, supporting page programming, and introducing unlock command sequences, all in C++ for embedded systems. These changes increased the reliability and maintainability of flash operations, reduced field risk, and improved traceability through structured driver-level updates and clear commit history, demonstrating depth in firmware and SPI protocol development.
