In April 2026, delivered cross-repo enhancements to watchdog timer test coverage for the Numaker_pfm_m487 board across Zephyr OS and NRF Connect SDK Zephyr. No major bug fixes were required this month; the focus was on expanding hardware validation and test automation. These changes improve hardware QA coverage and reduce integration risk for Numaker_pfm_m487 on watchdog timers.

March 2026 monthly summary: Delivered initial Nuvoton NuMaker M48x hardware support in Zephyr, including watchdog timer peripheral implementation and clock controller bindings with device-tree integration. Implemented the necessary devicetree bindings and clock node support, and added parsing/application of clock configurations in the SoC code to enable robust boot-time clock setup. This work establishes a solid foundation for M48x platform bring-up, improves system reliability through watchdog integration, and accelerates future hardware support and customer deployments.
