February 2026 monthly work summary focusing on key accomplishments and business value across Zephyr Microchip contributions.

December 2025 monthly summary for nrfconnect/sdk-zephyr development focusing on expanding hardware test coverage and testability across Microchip PIC32CX-SG and SAM E54 platforms. Primary work concentrated on enabling DMA, ADC, and comparator test workflows via device-tree and overlay updates, with commit-backed investigations and minimal regression risk. No major bugs fixed this month; improvements centered on feature enablement, testing overlays, and grid-aligned validation across boards.

November 2025 monthly summary for nrfconnect/sdk-zephyr: Delivered core Microchip G1 peripheral support (ADC, DAC, and comparator) for SAM E54-based targets, plus DMA G1 support for PIC32CX-SG. Implemented drivers, device-tree bindings, and pinctrl definitions, along with board metadata updates, test overlays, and build-time bindings to accelerate integration and validation. These contributions extend Microchip peripheral coverage, enabling higher performance data acquisition and signal processing pipelines, while maintaining alignment with Zephyr DT principles and Microchip platform consistency.

October 2025 monthly summary for zephyrproject-rtos/zephyr. This period focused on expanding hardware support and enabling flexible flashing workflows to accelerate development and testing cycles.

September 2025 monthly summary for zephyr project contributions. Focused on two key areas: (1) bug fix for header include style normalization in Microchip pinctrl for SAM D5x/E5x, and (2) reorganization of Microchip modules with Kconfig updates to improve structure, device family grouping, and consistency of external module references. These changes enhance build reliability, maintainability, and onboarding for Microchip-related work, with potential downstream improvements in CI stability and developer productivity.

August 2025 monthly summary for zephyr-testing repository. Focus this month was expanding Microchip PIC32 support in Zephyr to enable hardware bring-up and future expansion of the PIC32C family. Delivered initial board support scaffolding and configuration groundwork, readying the project for broader Microchip hardware integration.

July 2025 performance summary for nrfconnect/sdk-zephyr: Implemented initial Microchip SAM D5x/E5x support in Zephyr (SOC layer, DTSI integration) and updated the Device Family Pack; added SAM E54 Xplained Pro board support (board config, DTS, docs); adjusted build tooling (west.yml) to align with the new dfp; overall milestone enabling development and debugging for Microchip SAM MCUs.
