Worked on enhancing coverage reporting and build reliability in Espressif’s embedded systems ecosystem. In the espressif/idf-extra-components repository, extended the idf_create_coverage_report() function to support flexible coverage analysis by accepting custom source directories and gcov options, and updated esp_gcov to version 1.0.5 for improved tooling compatibility. Addressed CI build failures in espressif/esp-usb by resolving const qualifier violations in USB Host code, converting string arrays to const char * to comply with stricter compiler warnings. Leveraged C, CMake, and YAML configuration management to improve CI workflows, reduce manual intervention, and ensure ongoing development stability across both projects.
