February 2026 monthly summary for zephyrproject-rtos/zephyr. Key feature delivered: NRF54H20DK debugging support via West Attach, enabling debugging of the NRF54H20DK board across specific CPU variants and improving development workflow. Major bugs fixed: none reported this month. Overall impact: accelerated hardware bring-up and debugging cycles for NRF54 family, reducing time-to-insight and enabling more reliable software integration on Nordic hardware. Technologies/skills demonstrated: West-based debugging, board runners, cross-CPU variant support, Nordic NRF54 platform tooling, and Git-based contribution practices.

Month: 2025-11 — For repo nrfconnect/sdk-nrf, the month focused on stabilizing the linker and ensuring upstream compatibility. No new features were delivered this month; major effort centered on a critical linker-script bug fix that aligns with upstream Zephyr standards. The changes reduce build failures, simplify downstream maintenance, and position the project for smoother upstream integration.

May 2025: Key clock/RF reliability fixes across AmbiqZephyr and Nordic SDK. Delivered LFXO load capacitance corrections for nRF54L15-DK (ambiqzephyr) and RF load capacitance corrections for nRF54LV10-DK and nRF54LM20-PDK, plus a Bluetooth DTM errata 117 check fix to prevent hard faults. These changes improve clock accuracy, RF performance, and test robustness, with clear, traceable commits enabling rapid review and rollback if needed. Technologies demonstrated include embedded C, device-tree configuration, Zephyr, Nordic SDK, Bluetooth DTM testing, and strong version-control discipline. Business value: reduces field/QA failures due to clock/RF issues and strengthens release confidence.

March 2025: Focused on enhancing testing workflow and stability of the Radio Test tooling in the nrfconnect/sdk-nrf repository. Delivered a targeted RX buffer enhancement for the Radio Test Shell back-end to enable sequential command execution and easier pasting of multiple configuration lines, accelerating test setup and reducing configuration errors. This work improves developer productivity and reliability of radio feature validation, with clear commit traceability.
