The MCUXpresso Secure Provisioning Tool is a GUI-based application provided to simplify generation and provisioning of bootable executables on NXP MCU devices. It is built upon the existing security enablement utilities and takes advantage of the breadth of programming interfaces available on security-focused devices. The graphical interface provides a streamlined development flow, making it simpler to prepare, flash, and fuse images while leveraging and providing access to existing utilities. Advanced scripting can be achieved using the command-line interface, while even more advanced secure provisioning flows can be accomplished by modifying scripts generated by the tool. The MCUXpresso Secure Provisioning Tool currently includes support for devices within the i.MX RT crossover MCU series and the LPC5500 MCU series.
