Worked on the bazel-central-registry repository to upgrade the Pico SDK to version 2.2.2, focusing on enhancing build stability and preparing the platform for pre-release testing. The approach involved updating the MODULE.bazel file to reference the latest pre-release revision, refreshing dependencies, and introducing new toolchains to align with evolving build and test pipelines. Leveraged expertise in Bazel, dependency management, and version control to ensure compatibility with current toolchains and improve overall platform readiness. No critical bugs were addressed during this period, as the primary focus was on foundational improvements to support future development and streamline the upcoming release cycle.
