Worked on the zephyrproject-rtos/hal_rpi_pico repository to deliver a targeted dependency update, upgrading TinyUSB to version 0.18 across both the main and Bazel build systems. This effort focused on improving USB stack reliability for Raspberry Pi Pico hardware by integrating upstream bug fixes, performance enhancements, and new features from the TinyUSB library. The update involved careful dependency management and build system adjustments using Bazel, ensuring consistent behavior and reproducibility across configurations. By aligning submodules and Bazel dependencies, the work reduced future maintenance risk and stabilized USB functionality, demonstrating a methodical approach to build systems and dependency management in embedded environments.
