PROFILE

Greg Leach

Greg Leach developed and integrated hardware support for Ezurio boards within the Zephyr RTOS ecosystem, focusing on repositories such as AmbiqMicro/ambiqzephyr and nrfconnect/sdk-zephyr. He enabled new board variants, refined bootloader partition layouts, and resolved IRQ conflicts to improve test reliability and device interoperability. Using C, CMake, and device tree configuration, Greg delivered maintainable build systems and streamlined debugging workflows for platforms like the BL654 USB and Lyra DVK. His work included updating technical documentation and onboarding resources, demonstrating depth in embedded systems, Bluetooth Low Energy enablement, and cross-repository hardware integration to support robust customer deployments.
