Worked on enhancing debugging reliability for the Zephyr4Microchip/zephyr repository by addressing a stability issue in the probe-rs GDB server startup process. Focused on Python scripting and embedded systems, the developer implemented a targeted fix to improve SIGINT signal handling, ensuring the server no longer exited prematurely and that proper cleanup occurred at session termination. This adjustment, made within the scripts/runners directory, reduced debugging downtime and improved the robustness of developer workflows. The work demonstrated strong debugging and process control skills, contributing to more stable and reliable debug sessions for embedded development environments using Python and signal management techniques.
