Worked on Zephyr4Microchip/zephyr to deliver dual-bank flash support for STM32H7 boards, enabling reliable flashing of firmware images larger than 1 MB. Addressed the risk of image truncation by configuring DUAL_BANK in OpenOCD, allowing access to both flash banks and ensuring full-image write and verification, particularly validated with a 1.3 MB image on the nucleo_h7a3zi_q board. Demonstrated expertise in embedded systems and firmware development, focusing on OpenOCD configuration and STM32H7 hardware topology. Maintained clear documentation and commit hygiene, including Signed-off-by tags and descriptive messages, supporting maintainability and reproducibility for future development and deployment workflows.
