PROFILE

Chunlei Xu

During May 2026, contributed to the Zephyr4Microchip/zephyr repository by enabling hardware PWM support for the imx95_evk platform, focusing on device driver development and embedded systems. The work involved configuring pinctrl to mux GPIO_IO02 to the FlexIO1 peripheral and introducing a reusable overlay for the PWM API, allowing for cross-board compatibility with other NXP-based boards. All changes were documented and linked to a traceable commit, supporting future review and hardware bring-up. The implementation, written in C, established a foundation for PWM-driven applications such as motor control and LED dimming, with an emphasis on hardware interfacing and maintainability.
