In November 2025, Levizh developed a new board support package for the LXB723ZG-P1 development board based on the STM32H723, contributing to the levizh/rt-thread repository. Leveraging expertise in C programming, embedded systems, and RTOS development, Levizh implemented robust hardware initialization and improved build configuration. The work included refining linker scripts for both IAR and GCC toolchains, enabling environment-variable configuration, and removing redundant options to streamline maintenance. These changes resulted in faster prototyping, more reliable builds, and enhanced cross-team collaboration. The depth of the contribution addressed both immediate hardware needs and long-term maintainability for embedded development workflows.
