PROFILE
Kathleen Capella
Worked on the zephyrproject-rtos/trusted-firmware-a repository to enhance firmware reliability and portability by implementing explicit endianness handling for HOB binary packing. Developed Python utilities and Makefile logic to introduce a global endianness variable and helper functions, ensuring consistent byte order across architectures. Integrated a memory region descriptor for StandaloneMM compatibility, enabling overlap checks with Hafnium SPMC during HOB generation. Improved build system robustness by conditionally leveraging Poetry for dependency management, reducing CI fragility and ensuring reproducible builds. Focused on embedded systems, binary packing, and build systems, the work addressed cross-architecture challenges and stabilized the development pipeline for contributors.
