Worked on hardware bring-up and platform expansion for Zephyr on Microchip-based boards, focusing on adding Board Revision E support in the Zephyr4Microchip/zephyr repository. Developed a feature enabling configurable D14 and D15 pins for STM32U3 boards through solder bridges, allowing flexible pin mapping and improved compatibility with Revision E hardware. The implementation preserved support for previous board revisions, ensuring broad hardware compatibility without disruption. Utilized C programming and embedded systems expertise to deliver the update, with changes documented in a single, signed-off commit. The work strengthened Zephyr’s readiness for future hardware revisions and enhanced device driver development practices.
