Worked on the oe-alliance/build-enviroment repository to enhance build stability by updating the Meta-oe-alliance submodule to its latest revision, ensuring alignment with upstream dependencies. Focused on submodule management using Git and shell scripting, the approach emphasized reproducible builds and clear commit traceability. By maintaining current dependencies and reducing submodule drift, the work supported ongoing compatibility and laid a foundation for future CI improvements. No major bugs were reported during this period, reflecting a stable build environment. The technical effort centered on dependency alignment and process reliability, enabling faster iteration and supporting the long-term maintainability of the build system.
