Multi camera system using OV7670  and BF561

I would like to know if anyone has implemented more than two cameras on the same PPI lines.

I have developed a system in which 4 cameras are connected to PPI0 of BF561. At a time only one camera is turned on

this is done by the use of a port exapnder which accepts I2C commands.


The system works fine but sometimes when more than one camera is connected, I get green and pink lines in the image, sometimes it works

perfectly. I have tested and ensured connectivity and ensured that only one camera is on whereas the rest are powered down, but I still face the

same problem.


Can anyone suggest if they faced similar problem with a multi camera system on the same PPI bus with BF561?
