This document provides information on writing software to the nRF5340 devices and is intended for developers of flash programming tools.
It serves as a starting point for the nRF5340 device support in production tools and accelerates the engineering process of supporting the nRF5340 devices. This document describes a robust method for programming devices. You might not need to follow every step in some cases, for example, if the device has never been programmed before and its flash is completely erased, or if the device is unprotected.
