RPi Compute Module Instructions

Raspberry Pi Compute Module Flash Instructions

- Download and run the Windows installer to install the drivers and boot tool.

- Insert your Compute Module into the SODIMM connector of the Compute Module IO Board (CMIO).

- Plug your host PC USB into the CMIO USB SLAVE port, making sure J4 is set to the ‘USB Slave’ position.

- After a few seconds, the Compute Module eMMC will pop up under Windows as a disk (USB mass storage device).

Flash the Linux image File

Flash the device using Balena Etcher – download the install or portable version. Run the Balena Etcher program.

Select the installation image by clicking on the 'Select image' button;

Select the drive to write to by clicking on the 'Select Drive' button;

Start the flash process by clicking on the 'Flash' button;

This install procedure is a guide on how to install the minimum necessary to run a basic Raspberry Pi Lite install with

everything needed to run Desktop and command line, without all the extra software that gets installed with a standard

desktop install. This is mainly for use with Raspberry Pi (RPi) Compute Modules, but will also work on a standard

Raspberry Pi.

If you want to work with the Compute Module connected to the Compute Module IO Board (CMIO), or a Temco Controls

T3 Router as a standalone system, a HDMI display must be connected to the HDMI output on either board. For the

CMIO board use a USB Hub to connect either a Wi-fi dongle or USB > Lan adapter, and to connect a keyboard and

mouse. The T3 Router provides 3 USB ports so a USB hub is usually not needed. After the system has booted and you are

logged in (default user name for RPi is ‘pi’ and password is ‘raspberry’) access the RPi Software configuration tool by

The Raspi-config GUI appears. Select ‘Network Options’ from the list, then Wi-Fi from the options list.

The first time this is run on a new installation it will ask for Country to set the available Wi-fi channels according to your

Country.

Then it will prompt for Wi-fi SSID and Password.

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Using either a Linux or Windows System - add (or edit) the following;

network={

ssid="testing"

psk="testingPassword"

}

Replace “testing” with the SSID of your Wifi router, and “testingPassword” with your Wi-fi password. Save the file and

disconnect the IO Board from the computer.

sudo raspi-config

Select Interfacing Options.

Enable SSH (and SPI for use with the T3 Router).

To enable SSH on a ‘headless’ system you need to create a file named ssh on the boot partition of the Compute Module

using a Linux/Windows computer.

sudo apt update

sudo apt upgrade

sudo apt dist-upgrade

Then clean the installed packages to free up space, and reboot before installing the Desktop Environment.

sudo apt clean

sudo apt install --no-install-recommends xinit

sudo apt install lxde-core lxappearance

sudo apt install lightdm

sudo reboot

The System will boot into the Desktop Environment.
