Interface OV5647 with IMX-7 on MIPI CSI

Hi,

 

We are working on IMX7 based custom board. We are trying to interface OV5647 camera module on MIPI CSI interace. 

 

The kernel boot log file is attached. Once  the board is started we can see below video node.

 

root@imx7dea-ucom:~# v4l2-ctl --list-devices

i.MX6S_CSI (platform:30710000.csi):

        /dev/video0

pxp (pxp_v4l2_out.13):

        /dev/video1

root@imx7dea-ucom:~#

 

It seems link with IMX6. We have downloaded  a test application from :

https://linuxtv.org/downloads/v4l-dvb-apis/capture-example.html

We have changed  pixel format to V4L2_PIX_FMT_UYVY and cross compiled the application. On running the application,

we are getting  "timeout " as it is not getting any data.

 

root@imx7dea-ucom:~# ./capture_raw_frames_YUV422 -d /dev/video0 -o  test                                                                      

select timeout

root@imx7dea-ucom:~#

However, in on kernel message we are not getting any error message related to this.

So can anyone help us to add missing support for this interface ? Any help will be appreciated to narrow down the our problem.
