Image Flashing

USB2.0

The USB port is disabled by default on the CM4 to save power. If it needs to be enabled, you need to add the following to the config.txt file:

dtoverlay=dwc2,dr_mode=host

Then reboot it.

If you use the latest Raspberry Pi OS (image after October 30, 2021), USB2.0 defaults to OTG mode, and CM4 will report an error:

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

However, USB can still be used. If you want to remove this error, remove otg_mode=1 in [cm4] of config.txt, and add dtoverlay=dwc2, dr_mode=host (if you don't add it, USB can not be recognized).

1. Install Raspberry Pi Image

1) Write the Raspberry Pi image to the TF card, create a blank file named SSH in the root directory of the TF card to enable SSH, and edit the config.txt file in the root directory of the TF card to set the screen resolution. *Add at the end of config.txt file:

hdmi_group=2
hdmi_mode=82
hdmi_cvt 1920 1080 60 6 0 0 0

Make sure there are no spaces on either side of the equal sign.

2) Save and insert the TF card into the Raspberry Pi. Connect Magic Mirror to the network with an Ethernet cable. After powering on the Raspberry Pi, it will normally display after a few seconds.

3) After the Raspberry Pi starts normally, you can operate it with the mouse and keyboard, or through SSH or VNC.

Detect the sound card

Check playback: aplay -l

Check recording: arecord -l

2. Disable Power Saving

You can choose not to set it, depending on your personal needs
Open lightdm.conf

sudo vi /etc/lightdm/lightdm.conf

Modify lightdm.conf Find the [SeatDefaults] option and uncomment the line 'xserver-command', modify it as below:

#xserver-command=X

Modify it into:

xserver-command=X -s 0 -dpms

-s # –Disable the screen protection.
dpms Disable power saving.

Reboot.

sudo reboot
