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 be connected to the board using serial interface.

How to use Ethernet

IGEP COM AQUILA uses lightweight SSH server dropbear to accept SSH remote connections.

In your open serial interface connection, find the private IP assigned via DHCP:

root@igep0033:~# ifconfig eth0 | grep "inet addr"
          inet addr:192.168.2.173  Bcast:192.168.2.255  Mask:255.255.255.0

In my case was 192.168.2.173. 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'.
