Does the IMX8MP platform have a complete trusted startup document or link for the TPM?

Hello NXP community technicians:

I currently implemented TPM chip configuration under uboot and kernel, and I can also perform crypto metrics under system via TPM tool, PCR metrics on kernel files via uboot simulated TPM, and check accuracy under system, but the complete trusted boot process as well as automated checking operation is not known how to perform further;

Is there any documentation or links to refer to, and not sure of the legality of the current operation, looking forward to your suggestions and replies! Thanks!

Environment:

kernel: 6.6.52

rootfs: yoct5.0

Hello,

To implement HAB on i.MX8MP, you need to follow our secure boot guidelines. The key resources are:

i.MX 8M Plus Security Reference Manual .
i.MX 8M Plus Reference Manual.
i.MX Secure Boot on HABv4 Supported Devices (AN4581).
High Assurance Boot Version 4 Application Programming Interface Reference Manual (HABv4 API).
HABv4 RVT Guidelines and Recommendations (AN12263).
Code Signing Tool (CST).

Best regards.
