Feb 1, 2025February 2025 performance summary for NordicBuilder/sdk-nrf focusing on business value, reliability, and engineering execution. The month delivered a set of high-impact features, critical stability fixes, and platform optimizations across Edge Impulse integration, power management, release readiness, profiling, and quarantine hygiene. Key features delivered: - Edge Impulse: suppress build warnings, fix wrapper build warning, and adjust tests to use float constants to ensure consistent builds and test results. - CAF power management: introduce power_off event, improve shutdown flow, and use sys_poweroff API on nRF54H20 for reliable power-down behavior. - nRF Desktop release readiness: add dongle_small config for nRF52833 DK, enable LTO, enable LTO for sysbuild images, include a release note for LTO, fix MCUboot DFU image path, and adopt Fast Pair PSA crypto on nRF54L to strengthen crypto trust in provisioning flows. - Quarantine work: add nrf52810dmouse release from nRF Desktop and update quarantine integration; remove obsolete targets related to NCSDK-31675 to avoid stale references. - Platform optimizations: nRF Desktop platform optimizations for nRF52810/52820, including increased sys work queue and loader stack sizes to boost performance and stability. - nrf_profiler enhancements: improved stats calculation, interval plotting, test presets, and larger plots; updated logger names and related scripts for clearer diagnostics; fixed profiling for hid_report_subscriber_event. - Maintenance fixes: Kconfig warning fix for SW Split LL; removal of MPSL flash sync timeout workaround in nrf_desktop and Bluetooth fast_pair sample; and management of a revert for high Global Domain frequency on nRF54H20 when issues were observed. Major bugs fixed: - Quarantine cleanup: removal of NCSDK-31675-related targets to clean quarantine targets and avoid stale references. - Kconfig warning: resolved warning for SW Split LL to improve build cleanliness. - nRF54H20 frequency handling: reverted the high Global Domain frequency change due to observed issues, restoring stability. - Profiling: corrected hid_report_subscriber_event profiling to remove performance anomalies. - MPSL timeout workaround: dropped obsolete MPSL flash sync timeout workaround across nRF Desktop and fast_pair sample to align with updated MPSL behavior. Overall impact and accomplishments: - Strengthened release readiness with build-time optimizations and reliable DFU paths. - Improved device reliability and power efficiency via robust power-off handling. - Enhanced developer productivity through cleaner quarantine hygiene, better profiling visibility, and reduced build noise. - Demonstrated proficiency in embedded architectures, C/C++, build systems, security crypto integration, and performance instrumentation. Technologies/skills demonstrated: - Embedded C/C++, nRF SDK, and MCUs (nRF52810/52820/52833/54L/54H20) - Build optimizations (LTO), test adjustments, and DFU tooling (MCUboot) - Power management APIs (sys_poweroff), and Edge Impulse SDK integration - PSA Crypto usage for Fast Pair, firmware release engineering, and quarantine management - Profiling tooling and scripting enhancements for NordicProfiler - Quarantine management and clean-up practices
