PROFILE
Gregory Planchon
Gregory Planchon developed unified SPI support for STM32MP13 and STM32MP135F boards in the Zephyr4Microchip/zephyr repository, focusing on robust hardware interoperability and automated testing. He enabled board-level SPI functionality by wiring device-tree nodes and extending the clock driver to support SPI clock-rate readback, using C and DTS for low-level configuration. Gregory also created an overlay for SPI loopback testing, allowing validation across multiple speeds and improving test coverage for STM32MP135F DK boards. His work addressed integration gaps in SPI support, resulting in faster peripheral validation and enhanced platform readiness, demonstrating depth in device driver development and embedded systems engineering.

Feb 1, 2026February 2026 monthly summary for Zephyr4Microchip/zephyr: Delivered unified SPI support for STM32MP13/135F boards, including board-level enablement, device-tree SPI node wiring, clock-rate readback in the clock driver, and an overlay for SPI loopback testing across speeds. Implemented across four commits, improving hardware interoperability and enabling automated testing for SPI peripherals on STM32MP135F DK boards. Major bugs fixed include closing integration gaps in SPI by adding missing DT nodes and clock readback, enabling reliable loopback validation. Overall impact: strengthened platform readiness, faster validation of SPI peripherals, and more robust testing coverage. Technologies demonstrated include Zephyr SPI subsystem, device-tree bindings, STM32 clock controller integration, overlay-based testing, and West-based builds for STM32 targets.
