We provide a series of scripts to implement this functionality, saved in the rpi5_scripts directory.

* ./find_entity.sh
<code>$ ./find_entity.sh</code>
<code>Found mvcam @ i2c-4 entity on /dev/media3</code>
<code>Plese get frame from /dev/video0 and use /dev/v4l-subdev2 for camera setting.</code>
<code>Found mvcam @ i2c-6 entity on /dev/media0</code>
<code>Plese get frame from /dev/video8 and use /dev/v4l-subdev5 for camera setting.</code><br />After a reboot of Raspberry Pi 5, the media node and video node of the camera may change. Therefore, it is recommended to execute <code>./find_entity.sh</code> before performing subsequent operations to identify the device nodes.
The above prompt shows that the system has detected two cameras and their corresponding device nodes.
<code>i2c-4</code> corresponds to the CAM1 port on the board, and <code>i2c-6</code> corresponds to the CAM0 port on the board.
* media_setting_rpi5.sh
<code>./media_setting_rpi5.sh</code>
<code>Usage: ./media_setting_rpi5.sh veyecam2m/csimx307/cssc132/mvcam -fmt [UYVY/RAW8/RAW10/RAW12] -w [width] -h [height]</code>
<code>This shell script is designed to detect the connection of a camera on Raspberry Pi 5.</code>
<code> It utilizes media-ctl and v4l2-ctl commands to configure the linking relationships and data formats of the media pad.</code>
<code> Once completed, you can directly use /dev/video0 or /dev/video8 to obtain image data</code>
Before proceeding with further operations, it is '''necessary''' to execute this script to complete the configuration of parameters.
For instance，RAW-MIPI-AR0234M:
<code>./media_setting_rpi5.sh mvcam -fmt RAW8 -w 1920 -h 1200</code>
