Developed the initial board support package (BSP) for the DM-MC02 development board based on the STM32H723VGT6, focusing on enabling core hardware features within the levizh/rt-thread repository. The work established GPIO functionality using RT_USING_PIN and integrated UART1 to support the FinSH console, providing a foundation for further peripheral expansion. The BSP README was updated to document new board support, ensuring clear guidance for future development. This effort demonstrated proficiency in embedded C, STM32 microcontroller programming, and RT-Thread BSP patterns, delivering a production-ready starting point for DM-MC02 adoption and facilitating planning for subsequent hardware integration stages.
