I develop a board (base K230 CanMV).
I connect Gc2093 with CSI-2. I detect GC2093 with "i2cdetect -y 0" I get -> 0x37.
But, i can't get frame from CSI
When i run cmd: "ffmpeg -f v4l2 -input_format nv12 -s 1920x1080 -i /dev/video1 -vframes 10 -vf format=nv12 -c:v mjpeg_v4l2m2m -vsync passthrough -y output_%03d.jpg"
I get log:
