Disk encryption

Hi!

Is there a guide for how to use disk encryption with Jetpack 4.5? I’ve read https://docs.nvidia.com/jetson/l4t/#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/bootloader_disk_encryption.html# but it’s a bit hard to follow.

What I want to do specifically is have my Xavier NX storage sd card or emmc encrypted at rest and automatically decrypted at boot.

We are building an IoT device so credentials need to be stored on the device (I understand there is a hw secure key store on the xavier) and automatically applied without user input.

Thanks!

hello oscar.thorn,

disk encryption is only support with eMMC, it doesn’t support with external storage for r32.5 release.
