Platform Setup

This section of the guide covers platform assembly and electromechanical connections required to perform basic tasks.

The following items are noted as required, or highly recommended, to have on-hand before beginning to assemble the development platform.

Material List

Item Description

BIOS and Boot

During boot time it is possible to enter the BIOS menu.

This is most easily done using the expansion board’s HDMI output to a monitor and having a USB keyboard and mouse attached via a USB HUB to the USB Type-A connector on the expansion board.

Alternatively, this can be done using only the serial communication interface to a PC running a shell session manager, or in combination with the HDMI output as described below.

Camera Power Optimization

A few options are available to reduce the power consumption of camera use cases.

Exercise caution when applying these BIOS settings since they can have an undesired influence on other use cases by effectively restraining the CPU clock frequency management.

BIOS Settings

In the BIOS system, navigate to the following menu:

Device Manager -> System Setup -> CPU Configuration -> CPU Power Management

Making a Wi-Fi Connection

Connman

Connman is a connection manager daemon that lets you manage network connections over Wi-Fi* and is designed for use with embedded devices.

Starting connman

When the connman service starts, wpa_supplicant automatically starts. By default, connman starts at boot time. To prevent automatic start at boot time issue

Module Connectors

The Intel® Joule™ module utilizes two separate, connectors, (J6 & J7) to break out system buses, power and GPIO signals, while two additional connectors (JCAM1 & JCAM2) are dedicated to MIPI* CSI imaging devices.

Module Board-to-Board Connectors

The Intel® Joule™ module uses two board-to-board connectors to separate communication buses, power, and GPIO signals to the expansion board. Module connectors J6 and J7 mate with Hirose* Electric Co LTD part number DF40C-100DS-0.4V or other compatible hardware.

To properly interface with the module, keep the board-to-board connectors parallel, and maintain 19 mm between long-edge centerlines and 15.5 mm between short-edge centerlines, as shown in the figure below.
