2 Quick Start Guide
This section is a summary of the quick start guide is found at www.parallella.org/quick-start
Step1: Ensure that you have the required accessories
A high quality 2000mA rated 5V DC power supply with 5.5mm OD / 2.1mm ID center positive
polarity plug.
An ethernet cable
A fan (required for boards sold before July 10th, 2014, recommended for all others)
A micro HDMI to HDMI cable (not needed for headless option)
A USB male Micro-B to female Standard-A cable (not needed for headless option)
Step 2: Create a bootable micro-SD card
Burn a fresh Micro-SD card using the latest distribution.
Instructions for creating an SD card
Note: Burn a fresh SD card even if you were shipped a pre-programmed micro-SD card!
Step 3: Familiarize yourself with known issues
The board does get hot so you have to take precautions to cool the board properly. Before
letting the board run for hours, you must ensure that the board doesn’t overheat. (preferably by
using the xtemp utility.)
Boards used without a fan must be placed vertically.
The Parallella is sensitive to static discharge and must be handled appropriately.
If you were shipped a board before March 1st, 2014, then you must use a conforming powered
USB hub.
If you were shipped a board before July 10th, 2014 then you must use a fan with the board. (we
do still recommend a fan for all customers, especially if you are going to push the performance
of the board)
REV 14.09.09 13
Step 4. Connect peripherals, fit the heat-sink and apply power
Connect the cables as indicated by #1-4 in the picture above
Attach a heatsink to the Zynq device (#5 in right hand picture) OR install the new large heatsink
onto the Parallella board
Make sure a fan is directed at the board if required. A fan is required when using the small
heatsink (right hand picture above). With the large heatsink (left hand picture above) the board
will function in normal conditions without requiring a fan, depending on your usage. Monitor
the temperature using a utility such as xtemp, and keep the chip temp below 70 degrees Celsius.
Apply power (#6 in picture)
Step 5: Build and run a program
The system will boot and a login screen will appear.
Login with the username linaro and password linaro.

All four voltage rail outputs on the ISL9305 can be set by programming the appropriate registers within
the chip using the I2C interface. The Parallella on-board flash contains the appropriate programming
sequence to set the VDD_DSP rail to 1.0V and the VDD_GPIO rail to 2.5V automatically at boot time.
3.18 Parallella Supply Outputs
The Parallella can power expansion/daughter cards directly using the PEC_POWER connector.
The following voltages are available at the PEC_POWER connector:
5V
3.3V
2.5V
VADJ
VAD_GPIO
1.8V
1.35V
1.0V (Zynq)
1.0V (Epiphany)
The two on-board PMICs can deliver 1.5A on each step-down converter output and 300MA on each
general purpose LDO output. The amount of current drawn by the Parallella board will depend on the
level of activity on the board and the amount of current left over for the expansion card is yet to be
characterized.
NOTE: At this time, the PEC_POWER feature should be considered experimental. The safest power
solution for expansion cards is to: 1.) Have a completely independent power sub system or 2.) To use the
5V PEC_POWER rail.
Each one of the Parallella rails can also be powered directly from the PEC_POWER connector instead of
from the on board power management ICs. Each rail to be driven from an external connector would first
need to be powered down appropriately to avoid damaging the circuitry. To disable one of the ISL7307
outputs, pull down the corresponding REG_EN* signal available on the PEC_POWER connector. To disable
one of the ISL9305 outputs, program the appropriate registers using the I2C interface.
NOTE: There WILL be permanent damage to the board the power rails are driven incorrectly. Please
exercise extreme caution!
3.19 Parallella Expansion Connectors
The Parallella board has four expansions connectors placed on the opposite edges of the bottom side of
the board shown in Figure 2. For exact connector and placement information, please refer to the Parallella
mechanical drawings. The following figure shows the expansion connector placements as seen from the
bottom side of the board.
REV 14.09.09 20
Figure 6: PEC Placement Diagram
The Parallella Expansion Connectors uses the 60 pin BSH-030-01-FDA high speed connector from Samtec.
The corresponding mating connector to be placed on the expansion card is BTH-030-01-FDA. The

3.20 Mounting Holes
The board has four symmetrically placed mounting holes, one in each corner. The mounting holes have a
diameter of 0.125”.
Three of the mounting holes are connected to ground while the fourth mounting hole is floating by
default. This floating mounting hole can be connected to the 5V supply as a build or solder option, allowing
power to be easily applied to a stack of Parallella boards without the need for extensive 5V DC cabling.

Figure 9: Zynq Memory Map
The ARM communicates with programmable logic, GPIO connected to the programmable logic, and the
Epiphany by accessing the memory ranges shown in the table.
The Epiphany 32-bit memory space is mapped into the Zynq memory space allowing for easy sharing of
data and resources between the ARM and the Epiphany. The Epiphany address range is a matter of
convention and depends on the appropriate AXI master and slave interfaces being implemented within
the programmable logic on the Zynq.
REV 14.09.09 23
4.2 Epiphany Memory Map
The Epiphany chip is situated within a 1GB section within the Zynq host processor memory map. The offset
within the 1GB space occupied by an Epiphany coprocessor is set by the ROWID and COLID pins on the
Epiphany chip. The ROWID and COLID can be individually set on boards through the PEC_POWER
connector enabling direct board to board connection through the PEC_NORTH and PEC_SOUTH
connectors. By default the address locations of the Epiphany cores on Parallella-16 are as shown in the
Table below.

These design materials referred to in this document are *NOT SUPPORTED* and DO NOT constitute a
reference design. Only “community” support is allowed via resources at http://forums.parallella.org
THERE IS NO WARRANTY FOR THE DESIGN MATERIALS DESCRIBED IN THIS REFERENCE MANUAL, TO THE
EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE DESIGN MATERIALS “AS IS” WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY
AND PERFORMANCE OF THE DESIGN MATERIALS IS WITH YOU. SHOULD THE DESIGN MATERIALS PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION
This Parallella board was designed as an evaluation and development tool. It was not designed with any
other application in mind. As such, these design materials may or may not be suitable for any other
purposes. If used, the design material becomes your responsibility as to whether or not it meets your
specific needs or your specific applications and may require changes to meet your requirements.
For Feasibility Evaluation Only, in Laboratory/Development Environments: The Parallella Board is not a
complete product. It is intended solely for use for preliminary feasibility evaluation in
laboratory/development environments by technically qualified electronics experts who are familiar with
the dangers and application risks associated with handling electrical mechanical components, systems
and subsystems. It should not be used as all or part of a finished end product.
Your Sole Responsibility and Risk you acknowledge, represent, and agree that:
1. You have unique knowledge concerning Federal, State and local regulatory requirements (including but
not limited to Food and Drug Administration regulations, if applicable) which relate to your products and
which relate to your use (and/or that of your employees, affiliates, contractors or designees) of the
Parallella for evaluation, testing and other purposes.
2. You have full and exclusive responsibility to assure the safety and compliance of your products with all
such laws and other applicable regulatory requirements, and also to assure the safety of any activities to
be conducted by you and/or your employees, affiliates, contractors or designees, using the Parallella.
Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between
the\Parallella and any human body are designed with suitable isolation and means to safely limit
accessible leakage currents to minimize the risk of electrical shock hazard.
3. Since the Parallella is not a completed product, it may not meet all applicable regulatory and safety
compliance standards which may normally be associated with similar items. You assume full responsibility
to determine and/or assure compliance with any such standards and related certifications as may be
applicable. You will employ reasonable safeguards to ensure that your use of the Parallella will not result
in any property damage, injury or death, even if the Parallella should fail to perform as described or
expected.
REV 14.09.09 48
Certain Instructions: It is important to operate the Parallella within Supplier’s recommended
specifications and environmental considerations per the user guidelines. Exceeding the specified Parallella
ratings (including but not limited to input and output voltage, current, power, and environmental ranges)
may cause property damage, personal injury or death. If there are questions concerning these ratings
please contact the Supplier representative prior to connecting interface electronics including input power
and intended loads. Any loads applied outside of the specified output range may result in unintended
and/or inaccurate operation and/or possible permanent damage to the Parallella and/or interface
electronics. Please consult the System Reference Manual prior to connecting any load to the Parallella
output. If there is uncertainty as to the load specification, please contact the Supplier representative.
During normal operation, some circuit components may have case temperatures greater than 60 C as long
as the input and output are maintained at a normal ambient operating temperature. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense
resistors which can be identified using the Parallella schematic located at the link in the Parallella System
Reference Manual. When placing measurement probes near these devices during normal operation,
please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools,
only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in
development environments should use the Parallella.
Agreement to Defend, Indemnify and Hold Harmless: You agree to defend, indemnify and hold the
Suppliers, its licensors and their representatives harmless from and against any and all claims, damages,
losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in connection with any use
of the Parallella that is not in accordance with the terms of the agreement. This obligation shall apply
whether Claims arise under law of tort or contract or any other legal theory, and even if the Parallella fails
to perform as described or expected.
Safety-Critical or Life-Critical Applications: If you intend to evaluate the components for possible use in
safety critical applications (such as life support) where a failure of the Supplier’s product would reasonably
be expected to cause severe personal injury or death, such as devices which are classified as FDA Class III
or similar classification, then you must specifically notify Suppliers of such intent and enter into a separate
Assurance and Indemnity Agreement.
