Worked on the microsoft/mu_plus repository to enhance boot sequence reliability in embedded systems using C for firmware development and system programming. Addressed a critical issue where the boot process could deadlock if the Simple Rendering Engine was unavailable by implementing a retry mechanism that resets the Graphics Output Protocol pointer, ensuring successful SWM initialization. Validated the end-to-end boot flow on ARM64 hardware across various timing scenarios, confirming that system startup and user interface rendering remained stable regardless of component availability. Documented integration notes and test results to support ongoing maintenance, focusing on robust system availability and smoother user experiences.
