Worked on the zephyrproject-rtos/trusted-firmware-m repository, delivering two targeted feature enhancements focused on embedded systems and firmware development. Expanded the RSE-Comms payload capacity from 2KB to 4KB by updating configuration headers, enabling support for larger data transfers such as attestation requests. Improved observability in the RD-V3 system by enabling pretty-printed logging for the NI-Tower component, introducing a compile-time macro to control this feature and enhance log readability. Leveraged C and CMake to implement configuration-driven controls, allowing safer rollouts and easier future enhancements. The work emphasized maintainability, reliability, and debugging efficiency without introducing new bugs during the period.
