V4L2 mode for Raspberry Pi (view source)
Revision as of 10:20, 7 September 2021
, 10:20, 7 September 2021→Confirm the piOS version of your raspberry Pi
<code>sudo ./install_driver.sh [camera module]</code>
<code>sudo ./install_driver.sh [camera module]</code>
camera module：could be veye327,csimx307,cssc132.
camera module：could be veye327,csimx307,cssc132,veyecam2m.
'''Note: veyecam2m is a new version driver that can replace veye327 and supports all modules of the VEYE series with 200W resolution.'''
Note: For VEYE-MIPI-IMX327S or VEYE-MIPI-IMX462, please make sure '''hdver''' must >= 0x5.

=== 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.

Note: If there is only one camera, video node is always video0.
