May 2026: Implemented OpenThread-aligned RX failure handling in the IEEE 802.15.4 driver for Zephyr (Zephyr4Microchip/zephyr). Expanded RX failure reasons and mapped them to OT errors, updating otPlatRadioReceiveDone semantics per the spec. Commit 6fbd02b6828eb494d88b24a90a5c36dd6469f9c9 captured the changes. This work enhances error visibility, improves interoperability with OpenThread, and strengthens the reliability of the RX path.

March 2026 monthly summary for nxp-upstream/zephyr focusing on OpenThread alarm timing improvements via counter-driver integration, with added tests and docs to enable higher-precision scheduling and broader platform support.

February 2026 monthly summary for nxp-upstream/zephyr focused on delivering embedded driver support and hardware compatibility. Key feature delivered this month: Silicon Labs PROTIMER counter driver support for xg24 boards. The work integrates PROTIMER APIs with Zephyr's Kconfig and device tree to enable the driver and ensure hardware compatibility, establishing a stable foundation for timer-based functionality on xg24. Overall impact: Enables accurate timer operations on xg24 with the PROTIMER backend, improving real-time timing capabilities and expanding Zephyr support for Silicon Labs hardware. The change prepares for future enhancements in timer-driven features and related components across the project. - Commit 12136b4eda96cc9db06b059b7afe3ebefef4f4b1 added driver support and Kconfig integration for the Silabs xg24 counter driver (drivers: counter: silabs).
