Worked on the ArduPilot/ardupilot repository, focusing on embedded systems and firmware development using C++. Addressed a critical issue in the video transmitter subsystem by ensuring the configuration completion flag in AP_VideoTX is correctly set by AP_Tramp.cpp. This fix resolved a persistent problem where the OSD VTX_PWR indicator would blink indefinitely, improving both runtime reliability and user interface stability across video paths. The approach emphasized targeted debugging and clear, maintainable code changes, contributing to overall code health. No new features were introduced during this period, with efforts concentrated on maintenance and stability improvements within the existing firmware infrastructure.
