## Summary

Elecia White and Christopher White discuss their experiences with the Zephyr RTOS, highlighting its powerful ecosystem but steep learning curve, particularly regarding the complex build system, Kconfig, and device tree (DTS) configurations. They share specific debugging stories, including a hardware noise issue caused by a jumper cable and a Zephyr driver integration problem where a missing ST module caused build failures. The conversation also covers debugging techniques like rubber-ducking, the limitations of AI tools for embedded code, and career reflections on becoming a senior engineer.
