Hi, I am debugging a image sensor module called imx586, the resolution is 8000X6000, the sensor’s register has been configured successfully, 4 lanes of sensor hardware MIPI signaling are all outputting normally, but when I ran the command:
v4l2-ctl --set-fmt-video=width=8000,height=6000,pixelformat=RG10 --stream-mmap --stream-count=1 -d /dev/video0 --stream-to=imx586.raw
there was the following mistake:
