Delphixi worked on licensing compliance and reliability improvements across embedded systems projects, focusing on OpenSiFli/SiFli-SDK and 78/xiaozhi-sf32. For OpenSiFli/SiFli-SDK, Delphixi standardized license file naming and updated external dependency license texts, enhancing audit readiness and laying the foundation for automated license checks. In 78/xiaozhi-sf32, Delphixi addressed a timer thread crash under GCC by increasing stack size, stabilizing runtime behavior. Additionally, onboarding documentation was improved by updating the README with submodule cloning instructions, streamlining developer setup. The work demonstrated proficiency in C, Markdown, and license management, with a focus on maintainability and compliance in embedded RTOS environments.
