PROFILE
Valentin Caron
Worked on low-level firmware and driver reliability, focusing on embedded systems using C and Device Tree. In zephyrproject-rtos/trusted-firmware-a, restored RTC timekeeping on STM32MP15 ST boards by reconfiguring the RTC to use the LSE clock source and updating device tree parameters, ensuring system timers and security features remained stable during boot even when OPTEE RTC configuration was unavailable. In flipperdevices/u-boot, delivered a compatibility patch for the SCMI clock driver, implementing version-aware message length handling to support Clock Protocol 2.0. This reduced protocol errors and improved interoperability, demonstrating expertise in protocol implementation and embedded driver development.

Dec 1, 2024December 2024 monthly summary for zephyrproject-rtos/trusted-firmware-a focused on restoring reliable RTC timekeeping on STM32MP15 ST boards through clock-source reconfiguration and DTS updates. The change preserves time-based security features and system timers during boot and runtime by ensuring the RTC clock remains functional even when OPTEE RTC configuration is not ready.
