Rootfs encryption with iMX8MM

PMSTony — Mon, 06 Sep 2021 07:14:43 GMT

Hi,
I'm using imx8mm for project development and I've already signed and encrypt the uboot with HABv4 successfully. Now I'm trying to do the rootfs encryption but all I can found is related to storage encryption. (Section 10.5 of IMX Linux User Guide https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf And AN12714 "i.MX Encrypted Storage Using CAAM Secure Keys")

I'm using Yocto Zeus with BSP 5.4.70_2.3.0. Is there any further document I can reference to do the rootfs encryption?

Thanks in advance
