Overview

This is the 2/3 chapter of the Getting Started with IGEP AQUILA EXPANSION Tutorial Guide.

In this second chapter, we will learn some basics tasks. Upon completion, you will be ready to continue with chapter 3/3 that explains more advanced tasks.


What can I do

You must logged in the board.

Remote connection via Ethernet

Information.jpg If you aren't using a Linux operating system, use IGEP SDK Virtual Machine to connect to the board

In your Host Machine, open a terminal sessions set up an Ethernet alias for your network interface,

$ sudo ifconfig eth0:0 192.168.5.10

Connect to the board using the SSH protocol

$ ssh root@192.168.5.1

An empty password for root user should work to access to the shell prompt.

How to use audio HDMI

  • Download a WAV sample:
wget http://www-mmsp.ece.mcgill.ca/Documents../AudioFormats/WAVE/Samples/AFsp/M1F1-float32WE-AFsp.wav
  • Play the WAV sample:
aplay M1F1-float32WE-AFsp.wav

How to use LEDs

The board has three user leds available that can be controlled. In its simplest form, you can control of LEDs from userspace. LEDs appear in /sys/class/leds/ and you can turn on and off with following commands:

A detailed guide on how use GPIO-LEDS can be found by following this link: How to handle the gpio-LED

Control AQUILA COM Green LED

echo "1" > /sys/class/leds/com\:green\:user/brightness

You can turn them down using the same command and write '0' instead of '1'.

Control AQUILA EXPANSION Bicolor LED

echo "1" > /sys/class/leds/base\:green\:user/brightness
echo "1" > /sys/class/leds/base\:red\:user/brightness

You can turn them down using the same command and write '0' instead of '1'.

How to use EEPROM

IGEP AQUILA EXPANSION contains a 32 Kb EEPROM. EEPROM can be read and write via /sys/devices/ocp.2/44e0b000.i2c/i2c-0/0-0050/eeprom:

  • Write EEPROM:
echo "data" > /sys/devices/ocp.2/44e0b000.i2c/i2c-0/0-0050/eeprom 
  • Read EEPROM:
cat  /sys/devices/ocp.2/44e0b000.i2c/i2c-0/0-0050/eeprom

How to use USB OTG

The base can be powered though USB OTG connector. It's recomended use an external USB hub. Connect the USB Standard-A to Mini-B type cable between the base and the USB hub.
