====Overview====
====Overview====
RPI CM and Zero have a different MIPI CSI-2 port with standard RPI. And CM has can support dual cameras. Here I use a VEYE-MIPI-290/327 and a RPI CM3 as an example.
RPI CM and Zero have a different MIPI CSI-2 port with standard RPI. And CM has can support dual cameras.
For CM3, I use a Computer Module IO Board Plus designed by [http://www.waveshare.net/ WAVESHARE ELECTRONICS]. The official CMIO Board is similar.
For CM4，I use official CMIO board.
====Hardware Setup====
====Hardware Setup====
*Connect the VEYE Camera Module the CSI-2 port using FFC Cable（'''type A''').

Downloading dt-blob.bin file from [https://www.raspberrypi.org/documentation/hardware/computemodule/dt-blob-dualcam.bin link],rename to dt-blob.bin and upload it to /boot/,reboot RPI.
===== CM3 =====
CM3 use I2C-1 to control 2 cameras，It is time-sharing multiplexing.

===== CM4 =====
The CM4 module uses two I2C to communicate with two cameras respectively.
