In May 2026, delivered NVMEM-based MAC address retrieval and exposure of factory settings for Zephyr MCXW7x, enabling independent access via NVMEM and IFR0. This work decouples critical device identifiers and factory settings from flash, improving provisioning reliability, configurability, and security.

Month 2025-11: Delivered ZigBee connectivity enablement for NXP via IEEE802154 MAC in MCUX SDK within nrfconnect/sdk-zephyr. Implemented configuration to pull up MCUX components for NBU and integrated ieee-802.15.4 MAC with MCUX SDK 25.09.00 BLE controller support (MCXW71/MCXW72). Updated connectivity framework and HAL integration to align with MCUXSDK 25.09.00 release. This work extends NBU device connectivity options to ZigBee and improves interoperability for MCUX BLE controllers, reducing time-to-market for ZigBee-enabled products. Demonstrated proficiency with C drivers, Zephyr, MCUX SDK, West tooling, and cross-repo integration.

Month 2025-10 — Key features delivered: Merged the IEEE 802.15.4 MAC middleware 25.09 release with ZigBee support into the HAL NXP integration; added MCXW71/MCXW72 BLE controller and host libraries for ZigBee; introduced a new CONFIG_NXP_IEEE802154_MAC option; updated CMake to include MAC functionality. Major bugs fixed: None reported for this scope. Overall impact and accomplishments: Enables ZigBee-capable 802.15.4 MAC on NXP hardware, improving interoperability and time-to-market; aligns Zephyr HAL with MCUXSDK 25.09. Technologies/skills demonstrated: MAC middleware integration, ZigBee/IEEE 802.15.4, MCUXSDK 25.09, BLE controller libraries, ZigBee support, CMake/build system changes, and new configuration option CONFIG_NXP_IEEE802154_MAC.
