Worked on embedded systems development, focusing on hardware interfacing and device tree configuration for Zephyr-based projects. In the kholia/zephyr repository, addressed a critical MAX32666 flash issue by correcting device tree overlay configurations, aligning memory regions for code and storage, and ensuring reliable flash driver tests. Later, in Zephyr4Microchip/zephyr, enabled real-time clock (RTC) counter functionality on MAX78000EVKIT and MAX78000FTHR boards, enhancing timekeeping for time-sensitive applications. Utilized device tree, dts, and yaml to implement these changes, demonstrating a methodical approach to hardware bring-up, cross-board consistency, and robust driver development within the Zephyr embedded ecosystem over a two-month period.
