April 2026: Delivered documentation and multi-SoC support improvements for Zephyr AM243x/AM64x series, enabling reuse of generic docs across boards and simplifying onboarding. Also performed codebase organization improvements (K3 family structure, per-SoC Kconfig) and applied clang-format to ensure consistency. Unified AM243x AM64x documentation for the am243_evm, reducing duplication. Fixed AM64x Cortex-R interrupt count from 512 to 256 to align with hardware specs, eliminating potential build/configuration issues. These changes improve maintainability, reduce maintenance overhead, and accelerate multi-SoC integration.

March 2026: Delivered Main GPIO Domain - Full Pin Access (gpio-nexus) for nxp-upstream/zephyr, enabling access to all MAIN-domain GPIO pins beyond the first 32. MCU domain remains unchanged due to pin count. This feature unlocks richer peripheral configurations, simplifies hardware bring-up, and improves future expandability for AM64x-based platforms. Implemented via a gpio-nexus integration and corresponding device-tree adjustments, aligned with Zephyr conventions. Patch committed with 1d4501249f5766cd83ec58606081e3169d7d88a0.

February 2026: Delivered kernel/board-level TI K3 platform improvements in zephyrproject-rtos/zephyr, focusing on OpenAMP integration and timing accuracy. Implemented TI K3 OpenAMP resource table support enabling remoteproc booting from Linux with board-level enablement based on documented boot methods, enhancing cross-OS interoperability and system initialization management. Corrected Cortex-R clock speeds to reflect external crystal configurations for reliable timing and reduced boot-time clock sensitivity.

June 2025 monthly summary for zephyrproject-rtos/mcuboot: Delivered Cortex-R bootloader support and robustness enhancements to broaden platform coverage and improve startup reliability. Implemented Cortex-R cleanup routines, ensured interrupts are disabled/acknowledged, and reset processor state before final jump to the application. This work is traceable to commits 5a728be97ae032b19845b5351acea577c8cee917 and 83e2f9345e29f2f1ae487e5dca5f5cab9227f5e8.

Monthly summary for 2025-04 focusing on the Zephyr Project mcuboot repository. Delivered documentation-driven Cortex-R booting support updates and prepared the feature for customer adoption with release notes. No explicit major bug fixes documented in this period. The work aligns with Cortex-R boot roadmap and reduces integration risk for users deploying Cortex-R5 images.
