March 2026 monthly review for nxp-upstream/zephyr. Delivered Thread Stack Management Enhancements for Native Simulator, including thread stack information retrieval and POSIX stack bounds integration to improve thread management, stack overflow detection, and recovery in the native simulator. Implemented upstream synchronization by pulling latest changes and adding CONFIG_ARCH_POSIX_UPDATE_STACK_INFO to expose real stack bounds to thread info, ensuring CMSIS v1 compatibility. These changes reduce crash risk, improve reliability in simulation, and align with upstream main for easier maintenance.

February 2026 monthly summary for renesas/zephyr: Delivered a feature enhancement to the AT24 emulator by enabling address scanning through acknowledgment of zero-length writes. Implemented the zero-length write ACK in the emulator to align with hardware behavior and support address scanning workflows. This work was validated against a real device to ensure correctness. No major bugs fixed this month for this repository; the focus was feature delivery and reliability improvements. Impact: improved emulator fidelity, enabling faster hardware validation, simpler test patterns for I2C EEPROM address discovery, and stronger alignment between emulator and real hardware. Technologies/skills: kernel-style driver development, embedded emulation, hardware testing with real devices, code review and sign-off practices.
