====CM4的补充说明====
+
cm4支持两路摄像头同时使用,采用上面的步骤安装的dtbo将只能使用CAM1。如需使用两路摄像头,请按如下步骤:
+
=====更新dt-blob.bin=====
+
<code>sudo wget <nowiki>https://datasheets.raspberrypi.com/cmio/dt-blob-dualcam.bin</nowiki> -O /boot/dt-blob.bin</code>
+
=====更新双摄像头的dtbo=====
+
以csimx307为例:
+
+
<code>sudo cp raspberrypi_v4l2/release/driver_bin/$(uname -r)/veye_mvcam-cm4.dtbo /boot/overlays/veye_mvcam.dtbo</code>
+
+
<code>sudo reboot</code>
+
=====设备文件说明=====
+
CM4模块采用两路I2C分别与两个摄像头通信。
