Worked on the Wiwynn/OpenBIC repository to enhance boot drive handling reliability and diagnostics within embedded systems. Addressed a bug in bootdrive error logging and presence detection by refining the logic to reduce unnecessary log noise and improve diagnostic accuracy. Migrated bootdrive detection to a CPLD IO Expander on a separate bus, which helped prevent multi-master conflicts during hardware interaction. Integrated bootdrive detection into the platform initialization process using C, ensuring early and consistent boot state across different boards. This work focused on system debugging and platform initialization, resulting in more robust and predictable hardware startup behavior for the project.
