Hi all,
I have a problem for camera that can't find in /dev
I ever try to modify dtb about csi  parameters but no solved.
=======================================
main board : orange Pi PC 2
image : Raspbian_desktop_lxde_For_PC2_H5_V0_1.img.xz
camera board : gc2035

I had checked module using lsmod and plug-in gc2035,vfe_v4l2,...etc(see attached file)
and list boot log message also show can not find v4l2 device
  • [   15.851084] [VFE]Sub device register "gc2035" i2c_addr = 0x78 start!
  • [   15.851091] [VFE_ERR]Error registering v4l2 subdevice No such device!
  • [   15.865946] [VFE_ERR]vfe sensor register check error at input_num = 0
  • [   15.878249] [VFE]V4L2 device registered as (null)


I doubt it maybe hardware problem. Is any one have a idea?
THanks

I updated my process.
According to last issue for no find device video.
If you type
#modprobe -r -v vfe_v4l2
#modprobe vfe_v4l2
you will find a video device in your board and
also can run motion api.
But right now, I still got a problem for read
streaming by openCV. You can see as bleow image
