4 Preparing and running the tools to program the

Compute Module

The following steps explain how to use a Windows PC as a host system to program the Compute Module.

These steps will make the Compute Module appear as a mass storage device to the host PC so it can be

programmed with an OS image. Similar steps can be used for macOS and Linux based systems also –

please consult the Raspberry Pi documentation and website for the appropriate tools and steps.

4.1 Using a Windows PC as a host

1. Download and install either the official Raspberry Pi Imager application (recommended),

balenaEtcher or Win32DiskImager tool from the following locations. This will be used to write the

OS .img file to the Compute Module.

https://www.raspberrypi.org/software/

https://etcher.io/

https://sourceforge.net/projects/win32diskimager/

2. Download and install the Compute Module boot installer. This will install Windows drivers for

accessing the Compute Module as a mass storage device.

https://github.com/raspberrypi/usbboot/blob/master/win32/rpiboot_setup.exe

3. Download the OS image to be programmed to the Compute Module. The download may need to be

unzipped to reveal the .img file. Refer to the following section and the Raspberry Pi website for a list

of supported OSs:

https://www.raspberrypi.org/downloads/

4. A text editor that is compatible with UNIX type line endings, such as Notepad++, is highly

recommended for making boot configuration file changes from Windows. Notepad++ is available

from:

https://notepad-plus-plus.org/

5. Set the Compute Module to boot mode for programming.

To set programming boot mode:

a. Turn off the display’s AC power switch.

b. Connect a USB cable from the USB Micro-B connector on the Interface Board to the host PC.

c. Move the BOOT MODE switch on the Compute Module Interface Board terminal panel to

the programming boot mode position.
