  • Save and insert the micro SD card into Raspberry Pi.
  • Connect the Magic mirror to the network and power on Raspberry Pi.
  • After booting, you can access Raspberry Pi via SSH/VNC, or directly connect the keyboard and mouse.

Check the USB Audio Card

  • Test the sound output device:
aplay -l
  • Test the sound input device:
arecord -l

USB2.0

To reduce consumption, USB interfaces are disabled in CM4 by default. If you need to use USB ports, please add the following line to the config.txt file.

dtoverlay=dwc2,dr_mode=host

Then reboot the CM4. If you use the newest Bullseye image, the USB2.0 is set to OTG mode by default, and occurs the error in CM4: 

config failed, hub doesn't have any ports! (err -19)

To remove the errors, you can remove the line otg_mode=1 from the config.txt file and add the line: 

dtoverlay=dwc2,dr_mode=host

Kepp Display Always On

  • Modify lightdm.conf.
sudo nano /etc/lightdm/lightdm.conf
  • Find the line "Xserver-command" below the [SeatDefaults] section and change it from:
#xserver-command=X

to 

xserver-command=X -s 0 -dpms
  • -s # – set screen saver not enabled.
  • dpms turn off power saving management.
  • Then save and reboot:
sudo reboot

RS232

In /boot/config.txt, add dtoverlay=uart3.

sudo nano  /boot/config.txt
dtoverlay=uart3
#device name /dev/ttyAMA1

RS485

Open the Raspberry Pi terminal and enter the following command to access the configuration screen.

sudo raspi-config
