Basic MIPI-CSI OV5640 support is provided through the ov5640_mipi_nv.c driver (located in drivers/media/platform/mxc/capture/). The Kconfig symbol CONFIG_MXC_CAMERA_OV5640_MIPI_NV enables the driver. The bring-up BSP has the driver enabled by default.
Once the camera is hooked up, the following GStreamer pipelines can be used to use the camera:
export DISPLAY=:0.0
gst-launch-1.0 v4l2src device='/dev/video4' ! video/x-raw,format=RGB16,width=1920,height=1080,framerate=30/1 ! glimagesink
As noted in the BSP README the current GStreamer and driver combination does not provide a fluid video stream. This will be resolved in a future version of the BSP.
