March 2026 monthly summary for renesas/zephyr: Delivered CAN FD support for FlexCAN across MCXA156, MCXE31x, and MCXW71/72, enabling higher data rates and improved automotive communications. Implemented device-tree updates to expose CAN FD on the affected MCX platforms and consolidated changes into a cohesive patch set with clear commit messages and sign-offs for maintainability. No major bugs reported this month; this work establishes a robust foundation for higher-throughput CAN networks and accelerates automotive feature integration.

February 2026 — Zephyr4Microchip/zephyr: Delivered Automated CAN Testing Across Bitrates. Removed redundant board-specific CAN test configs for frdm_mcxe247, frdm_mcxe31b, and mimxrt1180_evk, enabling automatic bitrate exploration due to uniform 80 MHz CAN clocks. Streamlined CI tests, reduced maintenance, and improved cross-board coverage. Key commit: 3172a6ab6175f47f4344ecb9e08ce53b10b731fc.

January 2026: Delivered targeted CAN driver reliability improvements for zephyrproject-rtos/zephyr, and established formal CAN driver collaboration for ongoing maintenance. Implemented a focused interrupt handling fix to prevent unnecessary error handler execution and added a named collaborator to ensure sustained driver quality.

December 2025 performance highlights: Delivered critical hardware clock fix for GAU to ensure ADC accuracy, streamlined CAN/FlexCAN reliability, and improved maintainability through updated documentation and robust IRQ handling. Demonstrated strong cross-repo collaboration across Zephyr and NFC/NXP platforms, with measurable improvements in stability and code quality.

November 2025 monthly summary: Delivered robust FlexCAN driver enhancements and CAN timing/clock optimizations in the nrfconnect/sdk-zephyr, focusing on per-instance message buffers, device-tree driven resource allocation, and cross-SoC portability. Implemented compile-time MB allocation based on hardware capabilities, updated DT properties, expanded test coverage for CAN timing, and aligned clock configurations for stable performance. Also performed targeted maintenance to reflect hardware capabilities (e.g., removing CAN FD where unsupported) and refreshed header attribution. Business value centers on reliable, scalable CAN messaging, improved memory efficiency, and faster time-to-market for diverse SoCs.

October 2025: Targeted reliability improvement in the MCUX FlexCAN driver for the renesas/zephyr repository. Implemented a fix to allow loopback mode and CAN FD modes to be enabled simultaneously by clearing the Transceiver Delay Compensation ETDCEN bit when loopback is active. Validated on development boards with CAN FD and loopback configurations, reducing intermittent communication failures and improving developer confidence in testing CAN FD with loopback. This work enhances driver stability and testing coverage for CAN-related features, contributing to a more robust developer experience and customer reliability.
