îmx8 container encryption

anas-8888 — Fri, 03 Apr 2026 22:01:18 GMT

so i read the docs guide to encrypt the container

https://github.com/nxp-imx/uboot-imx/blob/lf_v2025.04/doc/imx/ahab/guides/mx8_mx8x_encrypted_boot.txt

but the problem is with enabling encrypted boot support,the cst tool 4.0.1 provided by nxp dosent have a code folder that contains backend ... so do i need the cst source code to compile the tool and enable encryption support?and if so from where i download the source code since i have only the cst 4.0.1 and it dosent contain container encryption support

Hello,

Seems that the documentation is a bit old, please note that this step is no longer needed in CST after version 3.0.0

Also, this App note is more up to date for encrypt boot:
https://www.nxp.com/webapp/Download?colCode=AN13994

And there is the SPSDK as well:

Best regards/Saludos,
Aldo.
