May 2026 monthly summary for Zephyr4Microchip/zephyr. Focused on stabilizing device-tree power-domain addressing and eliminating build warnings. Delivered a targeted fix for the main_timer0_pd unit address formatting in the Device Tree, removing a leading zero to satisfy the Device Tree Compiler and prevent potential boot-time issues. This work reduces noise in builds, improves hardware initialization reliability, and enhances maintainability for future Power Domain changes.

In 2026-04, delivered ARM64 SMP translation tables capacity enhancement to support 36-bit virtual addressing on modern SoCs, enabling more peripherals and improving scalability on TI K3 platforms.

For 2026-03, delivered end-to-end SCMI integration on the AM62L platform by consolidating transport, memory, and clock/power management under a unified SCMI framework. Implemented an SMC-based transport layer with shared memory and polling mode, expanded the SCMI message memory to support larger payloads, and wired clock/power domain management across UART, I2C, and SPI peripherals with corresponding device configuration options. Enabled AM62L EVM SCMI configurations to exercise centralized resource control, aligning with SCMI specifications and setting the stage for deterministic power/clock management and easier future peripheral support.

February 2026 monthly summary for Zephyr project contributions (2026-02). Focused on hardware platform support updates and cross-core UART consistency. Key achievements include: 1) AM6254/AM62x board configuration updates across SK-AM62 and SK-AM62B-P1, correcting SoC variant references to AM6254 and updating M4/A53 core board identifiers; 2) AM62L EVM documentation links refreshed to point to correct TRM and Linux SDK WIC image resources; 3) TI K3 UART driver enablement across AM6X A53 cores to align UART configuration with M4/R5 cores. Overall, these changes improve hardware compatibility, reduce onboarding time, and streamline debugging and support for AM6x platforms. Business value: clearer docs, consistent UART behavior, faster integration. Technologies/skills: kernel/board configuration, driver enablement, cross-repo collaboration, and documentation hygiene.

Monthly summary for 2026-01 focused on Zephyr AM6254 multi-core boot enablement and related documentation updates. The work delivered a concrete feature enabling all Cortex-A53 cores in the AM6254 device tree, along with documentation changes to reflect the boot sequence. This work improves multi-core performance capabilities and provides clear traceability for the change.
