=== Notes for CM4 ===
 +
Cm4 supports the use of two cameras at the same time. Following above steps will only be able to use CAM1. To use two cameras, follow the following steps:
 +
 +
==== Upgrade dt-blob.bin ====
 +
<code>wget <nowiki>https://www.raspberrypi.org/documentation/hardware/computemodule/dt-blob-dualcam.bin</nowiki></code>
 +
 +
<code>sudo cp dt-blob-dualcam.bin /boot/dt-blob.bin</code>
 +
 +
==== Upgrade dual camera version dtbo file ====
 +
Use csimx307,5.10.17-v7l+ kernel as an example：
 +
 +
<code>sudo cp raspberrypi_v4l2/release/driver_bin/5.10.17-v7l+/csimx307-dual-cm4.dtbo /boot/overlays/csimx307.dtbo</code>
 +
 +
<code>sudo reboot</code>
 +
 +
==== Device node description ====
 +
The CM4 module uses two I2C channels to communicate with the two cameras respectively.
