Raspberry Pi CM4 System Burn-in

Open the DIP Switch

• After opening the DIP switch, connect the Type-C port to the computer to enter burn-in mode.

Notes

1. Do not plug or unplug any devices except USB while powered on
2. The Type C port can be used for power supply or as a USB SLAVE interface to burn images
3. To ensure normal power supply for CM4, do not connect other devices when using the Type C port to burn images.
4. The module has no protection, please do not short-circuit the power supply.
5. The FLY motherboard does not support POE function! Do not use POE power supply

Notes

• Note: EMMC version cannot use SD card
• Note: The version without EMMC uses MICRO SD card to start, and a card reader is needed to burn the image
• The memory card is recommended to have a transfer speed of class10 or higher, it is recommended to use TF cards from brands such as SanDisk

• GOOGLE Drive:System Image

Image Download

• Download the system Click here to download and download the latest released system (or as shown in the picture).
• If the downloaded file is a torrent file, use Thunder or Comet software to download it again

• Image with desktop and recommended software (Raspberry Pi OS with desktop and recommended software), it is recommended to use storage space of EMMC 16G or CM4 lite 16G or above

Notes

The EMMC version needs to switch the dip switch to enter CM4 programming mode when power off, while the Lite version can directly burn the system card

Notes

• The EMMC version needs to enter the programming mode, the following is the method to enter the programming mode
• The Lite version does not need to enter the programming mode, just format and burn the image directly

rpiboot (Bootloader) Download

• Download and open the rpiboot software with administrator privileges Click here to download
• Install the driver and boot tool. After successful installation, there will be an rpiboot.exe application in the installation directory

Enter Programming Mode

• At this time, connect to the computer and power on the motherboard, the computer's device manager will identify a BCMxxx device

  

• Then run rpiboot

  

• Wait for the operation to finish, a USB drive letter will appear on my computer

Notes

Note: If the computer does not recognize the BCMxxx device, there may be a problem with one of the previous steps. It is essential to recognize the BCMxxx device for rpiboot to work, otherwise it will be invalid.

Format EMMC or SD Card

• Use the SDFormatter.exe click here to download software to format the SD card

  

• Or use the built-in disk management of WIN to delete partitions, after deleting the partitions, create a new partition

• The Raspberry Pi Zero2 and Zero2W need to modify the default display device, you can execute the following code directly to modify
• Please note that after execution, you need to restart to use

sudo sed -i 's/\/dev\/fb0/\/dev\/fb1/g' /etc/X11/xorg.conf.d/99-fbdev.conf
