Worked on stabilizing boot-time behavior in the zephyrproject-rtos/mcuboot repository, focusing on embedded systems and bootloader development using C. Addressed a critical issue in the serial recovery console by ensuring it initializes only once during the DFU wait phase, which preserved buffered data and prevented re-initialization errors that previously led to boot failures. This fix reduced the risk of field failures during OTA updates and improved device recoverability in DFU workflows. The solution aligned with Zephyr project requirements and resolved a root cause of serial recovery panics, demonstrating careful attention to reliability and robustness in embedded firmware workflows.
