Delphi Xi contributed to embedded systems projects by enhancing licensing compliance and improving reliability in C-based codebases. For the OpenSiFli/SiFli-SDK repository, Delphi standardized license file naming and updated external dependency license texts, reducing audit risk and laying the foundation for automated compliance checks. In the 78/xiaozhi-sf32 repository, Delphi addressed a timer thread crash under GCC by increasing stack size, stabilizing runtime behavior in RTOS environments. Additionally, Delphi improved onboarding documentation using Markdown, streamlining submodule setup for new developers. The work demonstrated attention to both code quality and process reliability, with a focus on maintainability and risk reduction across the projects.
