Can't capture data from adv7611 with CSI0 on MX6Q

I'm currently working with two sensor inputs on i.mx6q/linux platform.

One is adv7180 in PAL mode connected to CSI1 IPU2.

It works fairly well.


The other one is adv7611 connected to CSI0 IPU1.

We cannot get any data from CSI0 port by now.

The 'mxc_v4l2_capture.out' application gives

'ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0'.

It means that no data arrive CSI0.


We have setting adv7611 to work in free run mode,

which produces a 8Bit BT656 bit stream for 576i video mode.

The output Vsync, Hsync, Pixclk signals seem good.


And the register settings for CSI0 is basically the same as the settings of CSI1.


Any idea?
