It used to work, and I'll try to piece together what happened... Oh. Never mind. For me at least, the error messages about missing slaves are meaningless, and the mxc_v4l2_capture module continues to load: root@nitrogen6x:~# lsmod Module Size Used by mxc_v4l2_capture 21077 1 ipu_bg_overlay_sdc 3929 1 mxc_v4l2_capture ipu_still 1707 1 mxc_v4l2_capture ipu_prp_enc 4685 1 mxc_v4l2_capture ipu_csi_enc 2941 1 mxc_v4l2_capture ipu_fg_overlay_sdc 4760 1 mxc_v4l2_capture ov5642_camera 74186 0 camera_sensor_clock 721 1 ov5642_camera vivante 943 1 drm 140600 2 vivante I can also verify camera preview using the trivial gst-launch command: root@nitrogen6x:~# gst-launch mfw_v4lsrc ! mfw_v4lsink Which branch are you using?
