Camera for Pine64 in 2019

Ciao dears, I hope this is the correct section. I tried to find a solution in this and other forums, but I found dated post . I try to open one with the hope of solving the problem also for others

I'm having trouble getting the camera module s5k4ec to work for my pine64 running armbian 5.60

#cat /etc/lsb-release

DISTRIB_ID=Ubuntu

DISTRIB_RELEASE=16.04

DISTRIB_CODENAME=xenial

DISTRIB_DESCRIPTION="Ubuntu 16.04.5 LTS"

Here my armbianmonitor -u http://ix.io/1wU9. 

i've activated the module in/boot/armbianEnv.txt

verbosity=1
console=both
disp_mode=720p60
camera_type=s5k4ec
pine64_lcd=off
overlay_prefix=sun50i-a64
rootdev=UUID=97dbd6a3-cb6e-4dd8-a999-76e955b73f0e
rootfstype=ext4
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

I tried to follow https://github.com/avafinger/pine64_camera with no success; i'm stuck here "rename in SD card: [sdcard]/BOOT/pine64/sun50i-a64-pine64-plus.dtb to [sdcard]/BOOT/pine64/sun50i-a64-pine64-plus.dtb_no_camera" 

since i've [sdcard]/boot/dtb instead of [sdcard]/boot/pine64. Iìve tried to copy sun50i-a64-pine64-plus.dtb in /boot/dtb but it seems it no work - I don't have /dev/video0.

I also tried with motion, same results

[1] [NTC] [ALL] [Dec 27 15:24:20] image_ring_resize: Resizing pre_capture buffer to 1 items

surely I'm wrong with something since I'm a noob trying to become -at leats - good. 

someone who wants to give me some advice? 

Many Thanks,

Andi.
