Worked on the rdkcentral/meta-rdk-halif-headers repository to synchronize RDK HAL header versions with the GRT_TV_v8 tag, ensuring the stable2 build incorporated the latest fixes and features from multiple header repositories. Addressed header-version drift by updating version and revision hashes for components such as media-utils, hdmicecheader, deepsleep-manager, power-manager, devicesettings-hal, and tvsettings-hal. Focused on build system configuration using Bitbake, the work enhanced build stability and downstream compatibility. By resolving a key synchronization bug, the developer contributed to a more reliable integration process, supporting consistent header alignment across the ecosystem and improving maintainability for future development cycles.
