Raspberry Pi CM4 System Imaging

DIP Switch Introduction​

  • Please note the DIP switch status
  • TF Card Slot Usage Instructions

Precautions​

  1. Do not plug or unplug any device except USB while powered on.
  2. The Type C interface can be used for power supply or as a USB SLAVE interface to burn images.
  3. To ensure normal CM4 power supply, do not connect other devices when burning images using the Type C interface.
  4. The module has no protection, please do not short circuit the power.
  5. FLY motherboard does not support POE function! Please do not use POE power supply.
Notice
  • Note: EMMC version cannot use SD card.
  • Note: For non-EMMC versions, use MICRO SD card to boot, you need to use a card reader to burn the image.
  • Memory cards are recommended to have a transmission speed of class10 or higher, it is suggested to use TF cards from brands like SanDisk.
  • System image suitable for Raspberry Pi 3B/3B+/4B/CM4/5B.
  • This image comes pre-installed with Klipper, Moonraker, Mainsail, Fulidd, Klipper-Screen, etc.

Image Download​

  • Download the system by clicking here to download the latest released system (or as shown in the figure).
  • If downloading a torrent file, use software like Thunder or Comet to download.
  • The image with desktop and recommended software (Raspberry Pi OS with desktop and recommended software) is recommended for use with EMMC 16G or higher storage capacity for CM4 lite 16G memory card or above.
Notice

EMMC version needs to switch the DIP switch into CM4 burning mode while powered off, Lite version can directly burn the image to the system card.

Notice
  • EMMC version needs to enter burning mode before entering, see below for instructions on how to enter burning mode.
  • Lite version does not need to enter burning mode, just format and burn the image.

Download rpiboot (Boot Loader)​

  • Download and run the rpiboot software with administrator privileges by clicking here.
  • Install the driver and start tool. After installation, there will be an rpiboot.exe application in the installation directory.

Enter Burning Mode​

  • Connect the computer and power the motherboard. In the computer's Device Manager, a BCMxxx device should be recognized.

  • Then run rpiboot.

  • Wait until the process ends, a U drive icon should appear on your computer.

Notice

Note: If the BCMxxx device is not recognized, one of the steps above may have gone wrong. It is essential to recognize the BCMxxx device to run rpiboot effectively; otherwise, it will be ineffective.

Format EMMC or SD Card​

  • Use SDFormatter.exe software to format the SD card by clicking here.

  • Alternatively, use the built-in disk management tool in Windows to delete partitions and then recreate them.

  • Right-click on This PC -> Manage -> Disk Management -> Find the newly added drive (choosing the wrong one could lead to problems) -> Delete all partitions -> Create a partition (any file system). If the drive has been used for system installation, there might be two drive icons, ignore them and proceed with formatting or deleting partitions.

Burn Image​

  1. Use Raspberry Pi Imager by clicking here to burn the image.

  2. Before burning, configure username, password, and enable SSH.

  3. After burning, a U drive icon should appear on your computer.

Complete Burning and Restart​

  • After burning, disconnect the power, disconnect the connection to the computer, and set the BOOT switch back. Power up again.

Precautions for Raspberry Pi Zero2 and Zero2W​

  • These precautions are for using FLY-TFT screen with G2T.
  • For Raspberry Pi Zero2 and Zero2W, modify the default display device by executing the following code:
sudo sed -i 's/\/dev\/fb0/\/dev\/fb1/g' /etc/X11/xorg.conf.d/99-fbdev.conf
  • Please note that a restart is required after execution to take effect.
