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.
Contents
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.
Flash USB memory
uSD firmware contains the roofs available to write the firmware to the flash memory.
- Enter to the /opt/firmware and run the igep-flash script :
igep-flash --image /opt/firmware/core-image-validation-igep0033-20130916081322.rootfs.tar.bz2
When finish, power off your board, unplug the micro-SD card and power on the board. That's all, enjoy the new firmware running from the flash memory.
- NOTE: You can speed up flash procedure. By default the flash script runs the nandtest command to mark bad blocks, this can take a long time and in most cases is not necessary, you can speed up the flash procedure running the script as follows:
igep-flash --image /opt/firmware/core-image-validation-igep0033-20130916081322.rootfs.tar.bz2 --skip-nandtest
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'.
