Hello,
I am trying to use a Raspberry cam V2 on the CSI port with the RockPi 4 on Debian Buster.
I activated the overlay imx219, but cant get it to work.
using test_camera-rkisp1.sh in console fails (command unknown)
I also cant find the camera using OpenCV.
What am I missing here? The documentation in https://wiki.radxa.com/Rockpi4/hardware/camera/ is unfortunately not very detailed. Please help.
Is there a linux kernel/distrib version/status when the imx/ov camera really worked as radxa wiki says?
Read this post and ask the guy. He got the camera working, does not mention which one but i think the sensor is imx219, and that just needs the libcamera for AWB and 3A for a good image.
If you cannot find test_camera-rkisp1.sh, it is probably not installed. Here at the bottom they give a version with linaro which already includes that script -> https://wiki.radxa.com/Rockpi4/MIPI_Camera
Also, you can run it on a different OS installation, here is the content of test_camera-rkisp1.sh file:
bash$ cat test_camera-rkisp1.sh
#!/bin/sh
export DISPLAY=:0.0
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/aarch64-linux-gnu/gstreamer-1.0
#export GST_DEBUG=ispsrc:5
#export GST_DEBUG_FILE=/tmp/2.txt
echo "Start RKISP Camera Preview!"
su linaro -c " \
gst-launch-1.0 rkv4l2src device=/dev/video0 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=30/1 ! videoconvert ! autovideosink"
Command gst-launch-1.0 rkv4l2src device=/dev/video0 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=30/1 ! videoconvert ! autovideosink works after installing gstreamer.
I’ve been struggling with it for 1 week, I’ve downloaded all the referenced versions, none of them work.
And from that gstreamer example, only a gray blob comes out.
Look at the forum here, it doesn’t work for anyone. There are several years’ worth of error tickets, and 0 of them have been closed.
Have you tried it? No one has seen it in action yet 
From official rockchip documentation:
v4l2-ctl -d /dev/video0 --set-fmt-video=width= 1920 ,height= 1080 ,pixelformat=NV12 --stream-mmap= 3 --stream-skip= 3 --stream-to=/tmp/cif.out --stream-count= 1 --stream-poll
and
W= 1920 ; H= 1080 ; mplayer /tmp/cif.out -loop 0 -demuxer rawvideo -fps 25 \-rawvideo w=${W}:h=${H}:size=$((${W}*${H}* 3 / 2 )):format=NV12
Result: Black screen or gray noise.
Or
streamer -o 5 .jpeg -c /dev/video0
Black screen
“Best” result:
gst-launch-1.0 rkv4l2src device=/dev/video0 io-mode=4 isp-mode=2A ! videoconvert ! video/x-raw,format=NV12,width=1920,height=1080 ! jpegenc ! multifilesink location=%d.jpg
Dark green thing, barely recognized pictures.
Have you tried set example exposure?
v4l2-ctl -d /dev/video0 --set-ctrl 'exposure=1216,analogue_gain=10' or video1-2-3
Return error 
But if you think I can continue, I have several hundred pages of logs, commands, kernel versions, distribes and hardware.

Full raspberry camera documentations https://www.raspberrypi.com/documentation/accessories/camera.htmlWhen I first tried it, it was a sunny day and I was outside, and thought the camera worked because I could see the objects but they were white/greenish. With low light, nothing can be seen, I think the problem is something to do with the camera drivers
Hehehe, jeah “working” he got this nice pic:
Hahaha I meant I could take a picture(sorry if misunderstood), I’ve been still struggling to solve this lighting thing 
Btw I have the exact configuration you mentioned…
I think the camera is working. What you see is a ‘raw’ image from the sensor, which needs to adjust exposure and gain. This is done by libcamera or rockchip camera engine. Someone pointed out where rockchip prebuilt deb packages are in github. Try to install it, if there is an iqfile for your sensor, it will auto adjust when you grab the frame. You can also try collabora kernel which has support for imx219 and rockpi 4, also, see if this can help: https://lists.libcamera.org/pipermail/libcamera-devel/2020-February/006771.html
