Image Burning Steps

Note: The EMMC version cannot use the SD card.

rpiboot (Bootloader) Download​

WINDOWS​

Other Platforms​

Installation​

  • Disable antivirus software.
  • Install the drivers and boot tool. After installation, there will be a rpiboot.exe application in the installation directory.

Download the Burning Software​

Enter Burn Mode​

  • Connect BOOT to GND, or set the BOOT switch to ON. You can check the BOOT pin position on the product's WIKI page.
  • First, connect the Type-C interface (SLAVE interface) to USB and then connect the power. Some boards may require additional power.
  • At this point, when the board is connected to the computer and powered, the device manager on the computer will recognize a BCMxxx device.
  • Then, run rpiboot and select the corresponding executable program or script.
  • For example, if you are connecting CM5, the following will appear.
If you encounter the error "Failed to write correct length, returned -9" and it freezes, try updating `rpiboot.exe`.
  • Wait for the process to finish. A USB drive will appear in "My Computer".
Note: If the BCMxxx device is not recognized by the computer, it may indicate a problem with one of the steps above. It is essential that the BCMxxx device be recognized before running `rpiboot` for it to work.

  • If you are unable to burn the image correctly, try the following troubleshooting steps:

    • Ensure that your Compute Module version is correct. The eMMC version will have an additional IC. Only eMMC versions can be burned in this way.
      CM5
    • Try using a different USB data cable.
    • Try using a different USB port on your PC.
    • Try restarting the PC.
    • Try reinserting the CM5.
    • Try burning the image on another computer.
  • Note: If you are prompted to format, do NOT format the device.

Burn the Image​

  • Open Raspberry Pi Imager.
  1. Choose the hardware to burn (from step 1). For CM5, select PI5.
  2. Choose the image version. You can select the appropriate one for your needs (you can also choose to format or select your backup system).
  3. Select the drive letter to burn to. Only removable drives (USB extended drives) are supported.
  4. Once everything is selected, click NEXT. If Raspberry Pi OS is chosen, it will appear. If not needed, click "No". If you’ve saved configurations before, click "Yes". For first-time use, set up the username and password under "Edit Settings".
  5. A fresh system does not have a default username and password. You can configure them directly in the configuration interface. If you don’t configure them, you will need to connect a keyboard and mouse after boot to set them up.
  • Note:
    • CM4: If using the latest Raspberry Pi OS, USB2.0 is in OTG mode by default. On some baseboards with an added HUB chip, if CM4 reports the error:
      config failed, hub doesn't have any ports! (err -19)
    • USB will still work. If you want to remove this error, remove otg_mode=1 in the [cm4] section of config.txt and add dtoverlay=dwc2,dr_mode=host. If the system does not show this error, you can ignore it.

Burn Complete and Restart​

  • After the burning process is complete, disconnect the power, unplug the cable from the computer, disconnect BOOT, or set the switch to OFF. Power it on again.
