Dear NXP,

Platform: IMX8MNano EVK

OS: Yocto

I needs to enable configuration in yocto source to encrypt and decrypt the EMMC partition.

I unable to find exact guide to encrypt and decrypt EMMC Partition in yocto source itself.

I have FitImage (Kernel, dtb, Initramfs). Is there way for encrpt and decrpt the boot partition from u-boot

source.

I need some document or expert help to proceed further.

It is related to uboot and kernel config.

Here is commands:

bitbake linux-imx -c menuconfig

bitbake uboot-imx -c menuconfig

Thank you @Zhiming_Liu for the quick reply.

Is it possible to add encrypted partition in .wic (.wks) file ?
