February 2026 monthly summary for TF-M and Zephyr work across two repos. Key focus areas include delivering MCXA577 platform support for FRDM-MCXA577 and integrating MCXA577 TF-M across the Renesas Zephyr repository, along with testing enhancements, documentation, and coding-style alignment. The work tightens security model, improves platform reuse, and accelerates readiness for MCXA577 deployments.

January 2026: Implemented TF-M BL2 support for MCXN947 across multiple repos (trusted-firmware-m, Zephyr, and NRF Zephyr SDK wrapper), including partitions/flash base adjustments, updated tests, and broader sample support. Delivered FRDM-MCXN947 bootloader BL2 enablement with memory alignment checks, ensuring secure boot readiness and build configurability. Expanded PSA-based samples and PSA-Arch-tests coverage for MCXN947, plus IPC sample updates to reflect TF-M BL2 readiness. Across-repo alignment and testing improvements provide a solid secure boot foundation and streamlined certification readiness.

December 2025: Expanded TF-M platform coverage with mcxn947 as a non-secure target and integrated it into the Zephyr testing framework. Implemented cross-repo updates to TF-M samples and manifests to ensure IPC and regression tests run on mcxn947, enabling broader hardware validation and faster test cycles. No major bug fixes this month; primary contributions were feature delivery and configuration for new hardware support. Demonstrated impact by increasing platform compatibility and CI readiness, reducing manual testing effort.

2025-10 monthly summary: Focused on cross-platform driver management improvements and new board support in Trusted Firmware-M (TF-M).
