How can I get the CMOS image sensor access to the EVM8168?

If you are using Parrellel interface for CMOS snesor, yes you can.

The VIN port can be used.

Firstly,thanks for your reply.

Is the VIN port you said the external interface in the picture in the evm816xiodc_Schematics_RevC.pdf?

The EVM8168 has the external interface as follows named JP1.If it is not the VIN port ,which is it? 

Looking forward to your reply.Thank you very much.
