Hello.

I'm using TW2835 in freescale i.mx6q board now, and i get a problem.

I wired TW2835 camera to the CSI0 interface of the i.MX 6Quad

After I ran the camera application,it displayed black screen and got some error like below:

I used oscilloscope to detect the signals of hardware:
1)the CLKVDOX pin outputs 27M waveform
2)the HSYNC, VSYNC output always high
3) VDOX0~VDOX7 always high

I config registers almost like the Recommended Value in datasheet,.

Am i missing something? why the HSYNC, VSYNC, VDOX0~VDOX7 always being high?
