Overview

This is the 1/3 chapter of IGEPv2 Tutorial Guide.

In this first chapter, we will learn how to connect some peripherals, how to boot IGEPv2 and how to log into IGEPv2 via Ethernet.

Requirements

In this tutorial we are going to use the following peripherals:

• IGEPv2 with its power supply
• a monitor compatible with DVI-D
• a network cable.
• a USB keyboard and a mouse
• a PC with Linux or Windows

Getting started

Connect a DVI monitor

Basic

IGEPv2 has a HDMI connector with a DVI-D interface

Connect IGEPv2 to a DVI-D compatible monitor.

Know more

The Digital Visual Interface (DVI) is a video standard interface designed to provide very high visual quality on digital display devices such as flat panel LCD computer displays and digital projectors. It is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A).

Note that your monitor should be able to support 1024 x 768 @ 60 Hz, which is the default resolution in the preinstalled software.

Connect an Ethernet Network cable

Basic

Plug an Ethernet cable between IGEPv2 and your client machine (or any other network device with ethernet connectivity).

Know more

IGEPv2 comes with one 10/100BASE-TX Ethernet ports.

In the following chapters we will use ethernet to access IGEPv2 with IP configuration, send files, etc.

Connect USB devices (keyboard and mouse)

Basic

Connect a USB hub to the USB type-A connector (USB Host) in IGEPv2.

Then plug a USB keyboard and USB mouse to the USB hub.

Know more

Only USB 2.0 devices will work in IGEPv2, so if you connect any USB mouse 1.0 into the USB host connector without using a USB hub 2.0, it will not work.

Power up IGEPv2 (5V DC)

Basic

Once you have connected the peripherals you can apply power to your IGEPv2 (5V DCC).

Know more

Led's sequence

When you power up your board, you will also see how two red LED's light up while the system boots (the sequence will be different based on software version). After a few seconds, there is a fixed green led on.

Boot priority

IGEPv2 can boot from many other devices (listed by priority):

1. from USB
2. from UART3
3. from a MMC/MicroSD card
4. from OneNAND memory

Test the Demo software distribution

Basic

When IGEPv2 powers up, the desktop of the preinstalled software will appear on the screen.

You can use the mouse and the keyboard to test the demo applications.

Know more

All IGEP Processor Boards, including IGEPv2, have a pre-installed software in its flash memory which consists of a minimal Linux-based distribution with a lite X Window System and GNOME Mobile based applications created with Poky Platform Builder.

In the next chapter of this tutorial guide, we will learn how to update the pre-installed software of your board.

Log into IGEPv2 via Ethernet interface

Basic

You can log into IGEPv2 via many interfaces, such Serial, Wifi, USB-Ethernet Gadget, etc.

In this tutorial we are going to connect to the board via its Ethernet interface.

By default, all IGEP Processor boards have a static IP in their Ethernet interface which is 192.168.5.1

First of all, adjust the IP of your PC in order to be in the right subnet of IGEPv2, for example: 192.168.5.10

Linux:

If you are running Linux in your PC, open a Terminal session and set the IP of the Ethernet interface in which IGEPv2 is connected (for example eth0):

Run the following commands:

sudo ifconfig eth0 192.168.5.10 up

Windows:

If you are running Windows in your PC, depending of your OS version and your configuration the steps might be slightly different:

1. Click the Start button and select the Control Panel
2. Go to Network configuration
3. Right click the interface where IGEPv2 is connected (for example: Local Network) and select Propierties
4. Select the TCP/IP Internet Protocol configuration and click the Propierties button
5. Set a static IP (192.168.5.10) and 255.255.255.0 as network submask
6. Close all the dialogs

Now you are ready to log into IGEPv2 via its Ethernet interface. You just need a program with a SSH client.

In this tutorial we are going to use Putty, as it is a multi-platform program.

You can download it from its official page at:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Install and run Putty. It will look like this:

Follow these steps to connect to IGEPv2:

1. Select the SSH at connection type.
2. Insert the IP address of the target (IGEPv2 default IP: 192.168.5.1)
3. Ensure that the port is set to 22, the default for SSH communications.
4. Finally, press the Open button to start the SSH session.

If everything goes right, you will be able to access to an IGEPv2 console from your PC via Ethernet.

To login IGEPv2 use:

user:root
password: (no password for this user: press return)

Know more

In the pre-installed software, the default configuration for all the network interfaces is:

• eth0 - 192.168.5.1
• eth0:0 - via dhcp
• wlan0 - 192.168.6.1
• usb0 - 192.168.7.1

By default, the IP of the Ethernet interface is 192.168.5.1

Once you are logged in, you can see which interfaces are up in IGEPv2.

In the SSH console, run:

ifconfig

It will list all the active network interfaces.

If you want to change, for example, eth0 you can use the following commands (if you do it now, it will close the SSH session, as it will change the Ethernet IP):

ifconfig eth0 < new IP >

In order to make permanent changes (save the configuration upon next start), you will have to edit the /etc/network/interfaces file in your IGEPv2.
