Worked on the DragonBluep/openwrt repository, focusing on enhancing driver stability and reliability within embedded systems. Addressed four critical bugs in C, targeting thermal, UART, and PCS drivers to improve hardware correctness and maintainability. Solutions included correcting low-temperature threshold configuration, safeguarding UART baud rate calculations against out-of-bounds access, refining error handling in the thermal driver, and aligning bit-field mappings in the PCS driver with hardware specifications. These targeted fixes reduced misconfigurations and potential runtime errors, contributing to more robust kernel-level code. The work demonstrated a methodical approach to driver development and kernel maintenance using C and embedded systems expertise.
