CC6SBC parallel camera v4l2 slave not found.

0 votes
Now I try to evaluate CSI parallel camera interface with OV5642 camera module.
This module does not connect PWDN and RESET pin.

VCC, SCL/SDA, VSYNC/HREF, PCLK/XCLK and D0-7 is activated.

In my environment, Gstreamer and imxv4l2src show video streaming with only green.

I can not understand, why v4l2 can not found slave.

Please help..
