Worked on stabilizing Wi-Fi functionality within the Samsung/TizenRT repository by reverting previous updates to the Wi-Fi firmware and RA table, restoring the system to a known stable state. This involved careful rollback of changes in build systems and firmware development, with particular attention to the integration of RA table logic in build/tools/amebasmart. Assembly language was used to ensure low-level compatibility and reliability across wireless components. Release notes were updated to accurately document the rollback, maintaining traceability for future development. The work focused on system reliability, addressing a critical bug and preserving stability without introducing new features during the period.
