A Tutorial for Students

ABOUT PARALLELLA:
The goal of this tutorial is to allow you to set up your Parallella board for use in this
class. Be sure to follow these instructions closely, as you will need your Parallella
board for daily use in class.
These instructions are adapted from the original SD-card guide provided on the
Parallella website, which are slightly flawed.
Are you ready? Let’s get started!
THINGS YOU WILL NEED BEFORE-HAND:








A windows laptop (with SD card reader)
A Parallella board (desktop edition) with power cable
A 8GB+ microSD card w/adapter
1 micro USB to female USB adapter B cable
1 micro HDMI to female HDMI adapter cable
1 2port USB splitter
Keyboard, mouse, monitor w/HDMI connector.
1 set of parts for case assembly
This is what your
Parallela board should
look like when fully
assembled!
Connect the microUSB
and microHDMI cables.
Keep the microSD card
aside for now.

Note that the microUSB port next to the power cable is not used. Do not plug
anything into this port!
FORMATTING THE SD CARD:
The SD card will be used to house the operating system of our Parallella board. To
set up our system for initial use, we must first install an image of our desired
operating system on it. In essence, an image allows us to get a set of desired
software onto our system quickly and relatively painlessly. We provide the image
and all other requisite files for you in the par-master.7z file that you can download
from the course website.
1. From the Web: Download & Install Win32 Disk Imager (you may need to use
admin privileges).
2. Also Download/Install SDFormatter (you may need to use admin privileges)
3. Insert an SD card into SD card reader slot. Use the SD card adapter that came
with the microSD card.
4. Open the SDFormatter program. Select the drive the SD card is in (usually
the F drive). Be absolutely sure that the selected drive is the one associated
with the SD card!
Click “Option”. Set The format type to “FULL (Erase)” and Format size
adjustment to “ON”. Click “OK”, and then click “Format”. Wait until the
Formatting procedure is complete. Close the SDFormatter application.
5. Next open the Win32 Disk Imager program. Select the drive the SD card is in
(usually the F drive). Be absolutely sure that the selected drive is the one
associated with the SD card!
6. Download the zip file containing the Parallella image from the course
webpage to your Desktop and extract the files . Using the folder icon in the
Win32 Disk Imager program, navigate to where you downloaded the image.
Click on the “Write” button to begin writing the image to the SD card.
7. Once the process is done, it will appear that there is nothing on the SD card.
This is fine! Now, copy the remaining files in the parallella-files folder to the
SD card: devicetree.dtb, parallella.bit.bin and uImage. Do NOT copy
my_backup.img!
8. Once you are done, safely eject the SD card and remove the microSD card
from the adapter. Place the microSD card into the microSD card reader on
your parallela board. Connect the microUSB adapter to the USB splitter, and
attach the keyboard and mouse to the splitter. Connect the monitor’s HDMI
cable to the microHDMI cable.
9. Boot up the board. Eventually, a login screen should appear. Login in with
username linaro and password linaro.
TROUBLESHOOTING
If the board does not boot up:
 Ensure that when you attempt to boot the board, you see two LED green
lights. These should be constantly lit when the board is on. If the LEDs are
not green or if they are flashing, you may have a power issue. Please see your
instructor for next steps.

Ensure that cables are properly plugged in. Make sure that the microUSB
cable is plugged in as shown in the image on the front of this tutorial. It is
absolutely crucial that you do NOT plug anything in to the microUSB port
next to the power port. This microUSB port also acts like a conduit for power!

Next, try and hit the numlock key on the keyboard. Does it light up? If so, the
keyboard is registering. If your screen remains blank, there may be an issue
with the monitor. Make sure it supports HDMI.
EXPANDING THE FILE SYSTEM TO FIT THE DISK
The first thing we are going to do is resize the partition table.
On the command line:
dmesg | grep “root”
root=/dev/mmcblk0p2  this is your root partition
fdisk /dev/mmcblk0
puts you in its own special prompt. Type p for menu
type m for help (menu)
we need to change the partition table
delete partition 2 (this is the root partition) (d followed by 2)
create a new partition 2 (n followed by p (primary) value 2)
first sector: choose default
last sector: choose default
type p again to confirm
now write it to disk (w)
this should be all that you need
reboot immediately (if it doesn’t come up, you screwed up. Start over)
Now its time to resize
Use command: resize2fs /dev/mmcblk0p2
(wait)
reboot
BUILDING THE CASE
The 3D printed case is designed specifically for your Parallella board. Assembling
the case is very simple.
USMA students: You will be given a bag of parts to build the case for your
single node cluster. Ensure your bag of parts contains:
 2 base boards
 4 end connectors
 4 small screws
 4 little rubber feet (LRFs)
Place the 4 end connectors into one of the base boards. Carefully place the Parallella
board onto the base board (align on the pins). Using a non-magnetic screwdriver,
carefully attach the Parallella board to the first baseboard. The other base board is
the cover. Place the LRFs underneath the bottom baseboard. We do not recommend
that you place the LRFs under the connector positions if you plan to use it as part of
a larger cluster.
