Query on CSI Lanes in i.MX6Q

[kenyung]

May I ask a question?  I'd like to use 2 1080p MIPI cameras  to i.MX6Q, is it possible to use it as follow:

1.  two cameras use the same CLK LANE;
2. two cameras work at the same time;
3.   camera No.1 use the data lane 0~1, Camera No.2 use the data lane 2~3.

If it is feasiable， how to use the the same CLK LANE? is there a special chip to seperate one clk lane to two?

Hi Ken

in general one can connect up to 4 cameras to the MIPI CSI-2 interface.
For this you have to either use a MIPI CSI-2 hub (if anything
like this already exists) or multiplex the four streams in an FPGA.
Each camera in this case should use a different stream identifier (stream 0-3).

I am afraid there is no way for camera No.1 to use the data lane 0~1, camera No.2

use the data lane 2~3.

Best regards
igor
