Encrypt Root filesystem in I.MX93

[nileshvyas]

Hi Everyone,

I am using iMX93 EVK board and I want to encrypt rootfs/filesystem for security purpose. Is there any reference document for this to implement in yocto. I have gone through some of the available threads in the community and according to that, to do full disk/filesystem encryption in imx93 we have to go with the software-based DM-Crypt/LUKS, as CAAM hardware support is unavailable in imx93.

Our requirement is that we need to encrypt/decrypt filesystem at boot time, so please share some documents to do so with the imx93.

Regards,

Nilesh.

I'll ask the same: any update on this topic?

We are developing a new board with IMX93 and need filesystem encryption.
But NXP doesn't respond.
We have been waiting for the "i.MX 9 Family Safety Reference Manual" for some months.
