Worked on the zephyrproject-rtos/trusted-firmware-a repository to address build stability and cross-compiler compatibility issues affecting embedded systems. Focused on resolving a bug where newer compiler toolchains flagged floating-point instructions on architectures lacking FP support, the solution involved implementing safe, temporary enablement of floating-point operations during context save and restore. This approach ensured builds completed successfully across diverse toolchains while maintaining portability and reducing CI failures. Demonstrated expertise in build systems, compiler toolchains, and low-level debugging using Assembly, resulting in improved reliability and maintainability of the trusted firmware stack for the January 2025 development cycle without introducing new features.
