Contributed to the AMDESE/linux-aspeed repository by enhancing ARM64 watchdog support for the ASPEED G7 platform and improving SPI controller reliability on the AST2700. Developed and integrated new watchdog device nodes in the device tree, laying the foundation for future enablement and improved remote management in embedded systems. Addressed a user-mode initialization bug in the SPI driver by implementing a targeted dummy read, ensuring stable operation for devices dependent on user-mode access while maintaining compatibility with other platforms. Demonstrated expertise in C, embedded systems, and driver development, focusing on robust, maintainable solutions for hardware integration and platform stability.
