I am trying to follow various tutorials on full disk LUKS root encryption for Odroid C2 with a emmc. Every tutorial I have found makes use of a separate partition for boot. Something like /dev/sdx1 (vfat) 100Mb. Mostly raspi tutorials but a few others that are step by step instructions out there as well.

 

The armbian.img file does not have a separate boot partition when I use dd to transfer to emmc or sdcard. Do I just make a vfat partition on /dev/mmcblk0  (the emmc) and copy the /boot folder over to /dev/mmcblk0p1, and run dd again to put the arbian.img on /dev/mmcblk0p2?

 

Anybody know of a what I need to do to make that partition so I can try some tutorials and get initramfs to boot LUKS?

There is one great tutorial on this topic: 

 

Hi Igor, I did see that among the tutorials out there, and I did try to follow it but I didn't get very far...

root@odroidc2:~# lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
mmcblk0     179:0    0 116.5G  0 disk
`-mmcblk0p1 179:1    0 115.3G  0 part /

 

On your tutorial you have a boot partition. I used dd to write the img to the emmc. Armbian_5.30_Odroidc2_Debian_jessie_default_3.14.79.img

I have also tried a sdcard.
