Hello,
I’m using an arducam multi camera adapter v2.2. For the moment, I’ve two camera connected. Before I start the camera, I write these commands:
sudo apt-get install python3-pyqt5
sudo apt-get install python3-opencv
sudo apt-get upgrade
sudo apt install -y python3-kms++ python3-libcamera
sudo apt install -y python3-pyqt5 python3-prctl libatlas-base-dev ffmpeg
sudo pip3 install numpy --upgrade
sudo pip3 install picamera2
cd /tmp
wget https://project-downloads.drogon.net/wiringpi-latest.deb
sudo dpkg -i wiringpi-latest.deb
Then I update the kernel:
sudo rpi-update
And modify:
/boot/config.txt
# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details
# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16
# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720
# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2
# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4
# uncomment for composite PAL
#sdtv_mode=2
#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
# Uncomment some or all of these to enable the optional hardware interfaces
dtparam=i2c_arm=on
dtparam=i2c_vc=on
dtparam=i2s=on
dtparam=spi=on
# Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18
# Additional overlays and parameters are documented /boot/overlays/README
# Enable audio (loads snd_bcm2835)
dtparam=audio=on
# Automatically load overlays for detected cameras
camera_auto_detect=0
dtoverlay=camera-mux-4port,cam0-imx477,cam1-imx477
# Automatically load overlays for detected DSI displays
display_auto_detect=1
# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d
max_framebuffers=2
# Disable compensation for displays with overscan
disable_overscan=1
[cm4]
# Enable host mode on the 2711 built-in XHCI USB controller.
# This line should be removed if the legacy DWC2 controller is required
# (e.g. for USB device mode) or if USB support is not required.
otg_mode=1
[all]
[pi4]
# Run as fast as firmware / board allows
arm_boost=1
[all]
When I try to execute
init_camera.sh

And If i do
libcamera-hello --camera 0
Made X/EGL preview window

The hardware connection is correct. Should I modify something in the config.txt file? My kernel version is:
Linux raspberrypi 5.15.74-v7l+ #1595 SMP Wed Oct 26 11:05:08 BST 2022 armv7l GNU/Linux
