Which BSP are you using?

Can you verify your driver is loaded or not?

Thanks

Hi,

Can you just confirm that OV5640 camera is enabled in your kernel configuration?

if OV5640 is configured as a module than you need to first modprobe it.

Thank

i run the modprobe command:

modprobe ov5640_camera_mipi

then i get:

mxc_v4l2_master_attach: 0

mxc_v4l2_master_attach: ipu1:/csi1 attached ov5640_mipi:mxc_v4l2_cap2

camera ov5640_mipi is found
