Dhivya Dilangovan focused on enhancing the reliability of HDMI video initialization within the rdk-halif-device_settings repository during February 2025. She addressed a critical bug by enforcing the correct sequence of function calls, ensuring dsHdmiInSelectPort() is invoked before dsHdmiInScaleVideo() and dsHdmiInGetCurrentVideoMode(). This adjustment resolved issues stemming from misordered calls, leading to more stable video mode operations. Dhivya updated the associated test coverage to validate the new initialization logic, contributing to improved code stability. Her work leveraged expertise in C, API development, and embedded systems, demonstrating careful attention to system-level reliability and maintainability in driver development.
