Got Rock 5B working by following the guide (keyboard unlock only, without SSH - as desired). Thank you very much!
 
However, at least with the following images:
 
* Armbian_24.8.1_Rock-5b_bookworm_current_6.10.6_cinnamon-backported-mesa_desktop.img.xz
 
* Armbian_24.8.1_Rock-5b_jammy_current_6.10.6_kde-neon-kisak_desktop.img.xz
 
# cat /etc/resolv.conf > etc/resolv.conf  
does absolutely nothing, have to create the file manually and set desired DNS server there.
 

The tutorial and automated script have been updated for Debian bookworm and Ubuntu noble images. Here's a summary of the changes required to make everything work:
replace eth0 with end0 replace cryptsetup-bin with cryptsetup replace lsinitramfs /boot/initrd.img* with lsinitramfs /boot/initrd.img-* replace etc/dropbear-initramfs with etc/dropbear/initramfs replace etc/dropbear-initramfs/config with etc/dropbear/initramfs/dropbear.conf before exiting the chroot, execute ssh-keygen -A

@DIYprojectz: It should be possible to put the encrypted root filesystem on a different device than the boot partition, though I've never tried it with an SoC or Armbian. Thanks for the idea. I promise to look into it, but don't expect immediate results as I'm busy with other things at the moment.

It depends whether you want to add expansion board someday or not. If you do, 14x14x6 heatsink is the better choice, otherwise choose 14x14xsomething according to your desire and budget. I would recommend a fan regardless, those things get hot. You can read about mounting a fan here (SBC is very similar Orange Pi R1, fan mounts the same). Here you can buy the heatsinks, check Aliexpress too maybe they are cheaper there. I also strongly suggest cutting one of the heatsinks to fit on the RAM module, it benefits too.
