Worked on the rdk-halif-device_settings repository to improve HDMI video initialization reliability within embedded systems. Addressed a bug by enforcing the correct sequence of function calls, ensuring dsHdmiInSelectPort() is invoked before dsHdmiInScaleVideo() and dsHdmiInGetCurrentVideoMode(). This adjustment resolved issues caused by misordered calls, leading to more consistent video mode operations and reducing runtime errors during HDMI setup. Updated the test suite to validate the new initialization order, enhancing code stability. Utilized C for driver and API development, focusing on robust integration with hardware interfaces. The work contributed to smoother video experiences and improved maintainability of the codebase.
