Hello Forum Members

I have a NanoPi Duo 2 and an OV5640 camera I would like to work together.
The duo2 is running the following image: nanopi-duo2_sd_friendlycore-focal_4.14_armhf_20210618.img
The OV5640 camera is connected as it supposed be, same as here: http://wiki.friendlyarm.com/wiki/index. ... era_OV5640
On the system I see the camera connected, i get the following result for 'v4l2-ctl -d /dev/video0 -D':
pi@NanoPi-Duo2:~$ v4l2-ctl -d /dev/video0 -D
Driver Info:
Driver name : sun6i-video
Card type : sun6i-csi
Bus info : platform:camera
Driver version : 4.14.111
Capabilities : 0x84200001
Video Capture

Extended Pix Format
Device Capabilities
Device Caps : 0x04200001

Extended Pix Format

Running mjpg-streamer return this:
root@NanoPi-Duo2:~/C/mjpg-streamer# ./start.sh
MJPG Streamer Version.: 2.0
i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 640 x 480
i: Frames Per Second.: 30
i: Format............: YUV
i: Display framebuffer: /dev/fb0
i: JPEG Quality......: 90
Unable to set format: 1448695129 res: 640x480
Init v4L2 failed !! exit fatal
i: init_VideoIn failed

I cannot make the camera work. How can I proceed?
Compared to other RasPi systems, npi-config has no option for enabling the camera. How can I enable it on this system?
I tried to install another driver as 'sudo modprobe bcm2835-v4l2'
but returns modprobe: FATAL: Module bcm2835-v4l2 not found in directory /lib/modules/4.14.111

under 'ls /dev' I have video0 always, when the camera is connected and I have it too when the camera is disconnected.
Any help is welcomed.

Thanks!
