Secure Boot on i.MX 8 and i.MX 8X Families using AHAB

This document serves as a comprehensive guide to implementing secure boot on NXP's i.MX 8 and i.MX 8X applications processors. It focuses on the Advanced High Assurance Boot (AHAB) component, which ensures the execution of trusted and authentic code from the initial boot stages.

The application note details the secure boot architecture, the implementation process, and key features of the Security Controller (SECO) firmware. It is intended for developers and system designers who need to understand the procedures for signing boot images and designing software for AHAB-enabled processors.

Key topics covered include the secure boot flow, container authentication, the role of the Code Signing Tool (CST), and SECO functionalities such as lifecycle management and event verification. For detailed technical guidance and examples, refer to the U-Boot project documentation.
