I try to boot from an encrypted sd card but it's not possible. What have I missed?
Main setup was done as shown here: Installing Ubuntu Rootfs on NXP i.MX6 boards
The first partition is vfat and the second one ext4 with LUKS.
On boot I get "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block"
What's necessary for booting? Unfortunately I found hundreds of tutorial how to sign uboot but nothing related encrypting root fs of Linux and booting into it.
Storing the key will be a separate question. For the moment I would be happy if key file is stored on vfat partition (partition one on sd card)
Thx in advance!
