Jan 1, 2026Month: 2026-01 — Summary: Key features delivered include ETL-driven runtime, clocks, and logging improvements across UART, clocks, and logging; introduced common ETL-based clock implementations, explicit clock durations, and etl::print-based startup logging; upgraded ETL to 20.45.0 and refactored to etlImpl with platform-specific interfaces (etl_get_high_resolution_clock, etl_get_system_clock, etl_get_steady_clock, etl_putchar); defined explicit chrono durations to align with OpenBSW; removed redundant StderrLogger. Major bugs fixed: removed unused StderrLogger to fix linker inconsistency and ensure correct logging backend. Documentation and licensing updates: improved build/setup instructions, PR tagging for hardware tests, Windows/Linux build doc alignment, and corrected links in NOTICE.md to reflect accurate versions. Overall impact: improved runtime reliability and maintainability, cross-platform consistency, and licensing compliance. Technologies/skills demonstrated: ETL library usage, platform-specific abstractions, C++ refactoring, cross-platform build/docs hygiene, and logging improvements.

Aug 1, 2025August 2025: Focused on build reliability and cross-compiler compatibility for esrlabs/openbsw. Implemented a targeted bug fix to ensure initializer_list header is included for clang builds when STL is disabled, preventing missing std::initializer_list definitions in etl_profile.h. This reduces CI failures and stabilizes downstream usage.
