Worked on enhancing the stability of the zephyrproject-rtos/trusted-firmware-a repository by addressing a runtime error related to MECID platform hooks. Focused on embedded systems and firmware development using C, the developer implemented a conditional check to ensure the MECID update hook is only invoked when the FEAT_MEC capability is present. This approach prevented errors on platforms lacking FEAT_MEC support, thereby improving runtime stability and cross-platform compatibility for MEC updates. The contribution aligned with platform-agnostic maintenance goals, resulting in a safer and more robust update path for MEC-related features across supported hardware environments within the firmware codebase.
