During April 2025, Brule focused on improving hardware compatibility for Raspberry Pi 5 within the flipperdevices/u-boot repository. He addressed UART reliability by implementing a fix that synchronizes the UART clock frequency between the firmware Device Tree and the main Device Tree, ensuring the correct clock is applied during boot and runtime. Working primarily in C and leveraging expertise in Device Tree and embedded systems, Brule validated the solution to reduce UART misconfiguration issues. He also documented the changes to support future maintenance and onboarding. The work demonstrated a targeted, in-depth approach to firmware development and hardware-software integration challenges.
