I want to use the ipu2 csi1 for adv7180 camera,but i fail.

I have use the tips :

iMX6DQ ISL79985/79987 MIPI CSI2 CVBS camera surround view solution for Linux BSP 

and the boundarydevice's kernel.

the adv7180 driver is ok,but when i open the camera app,it send:

ERROR: v4l2 capture: mxc_v4l2_prepare_bufs buffers not allocated,index=0, length=622080
ERROR: v4l2 capture: mxc_streamon buffer has not been queued yet


the OS is the android4.4.2 android android5.1.1, the errors is the same. 


what's the problem?
