Krescue + VIM3 + MIPI camera not working

The camera is now available on /dev/camera0

I can run guvcview and see a 4K image at 1fps from the desktop.

So the camera/driver can capture 4K resolution, but at an unacceptable low fps.

I have also stopped the desktop and run the cli test app mentioned by @CodeLogist here:

v4l2_test -c 1 -p 0 -F 0 -f 0 -D 0 -R 1 -r 2 -d 2 -N 1000 -n 800 -w 0 -e 1 -I 0 -b /dev/fb0 -v /dev/video0

This can start the camera and show a decent framerate. But its only 1920x1080.

If I choose a higher resolution I get a segmentation fault:
v4l2_test -c 1 -p 0 -F 0 -f 0 -D 0 -R 0 -r 2 -d 2 -N 1000 -n 800 -w 0 -e 1 -I 0 -b /dev/fb0 -v /dev/video0

I need to prove that the sensor / driver can retrieve 4K at higher than 30fps.

I do not need to encode the image so I dont need encoder capability, bust 30fps access to the input image for further processin.

Can anyone help?
