Hi Mike, NuttX + Espressif's SoCs are intended to be built with optimization enabled. Otherwise, few practical applications would be possible and you'd need to reconsider stack sizes, for instance. So, please don't disable optimization while building practical applications.
Usually, it isn't needed to disable optimization to debug the code, but If you really need to turn it off to debug a specific function, consider using the attribute `__attribute__((optimize(0)))`.
