Introducing Ember Development Kits
2.1
Overview
The EM35x Development Kit is used for application design and development. The Development Kit contains a
variety of hardware for quickly creating a prototype of the customer’s hardware, EmberZNet PRO, Silicon Labs'
implementation of the ZigBee Pro stack software specification, and various development tools which enable the
development of the customer’s application software.
EmberZNet PRO runs on top of an IEEE 802.15.4-compliant radio and link layer software. EmberZNet PRO is a
self-organizing, self-healing mesh networking protocol stack. Combined with the powerful IEEE 802.15.4
compliant Ember radios, the EmberZNet network stack provides complete networking services from the physical
layer up to a reliable application profile support layer. The stack produces networks that are reliable, flexible,
secure, and easy to use.
EmberZNet PRO 1 provides a common Application Programming Interface (API) that utilizes the underlying layers.
This API provides support for the following layers of the Open System Interconnection Reference Model (OSI
Model):
•
PHY: radio control
•
MAC: medium access
•
LINK: route discovery
•
NETWORK: routing, association
•
APPLICATION: Application Profile Support for reliable message delivery
The EmberZNet PRO stack can be used to build ZigBee-based applications. Applications that are built on this
stack benefit from the following features:
•
PHY and MAC layers comply with the IEEE 802.15.4-2003 standard
•
LINK and NETWORK layers comply with the latest ZigBee specification
•
The APS layer provides the interface to the application for data transfer and management, including
reliable transport and binding.
The Development Kit includes InSight Desktop which facilitates application development and debugging. InSight
Adapters (ISA3s) incorporate Power-over-Ethernet (PoE) capability, which can simplify node deployment in the
test environment. Breakout Boards provide a direct connection for debugging customer-designed hardware. For
detailed information about the Ember customer hardware debug interface, see document 120-2009-000, the
EM35x Breakout Board Technical Specification.

Hardware
•
Breakout Boards serve as test beds for network hardware and applications. Each Breakout Board has
an associated EM35x Module, which can be deployed as a node within a network application. Each
Breakout Board connects with an InSight Adapter (ISA3) through two communication links: the InSight
Port (ISP) and the DEI Port. This allows the Breakout Board’s EM35x Module to interface with InSight
Desktop (ISD) through the ISA’s InSight Port and its wired Ethernet connection. These interconnections
are described later in this chapter. The Breakout Boards also have a prototype breadboard area for
application-specific hardware development.
•
EM35x modules contain the Ember EM35x System-on-Chip (SoC) solution providing a complete radio
and microcontroller solution. All modules are pin-compatible, and they can be directly attached to a
Breakout Board.
•
InSight Adapters (ISA3s) each connect a Breakout Board to the Ethernet. Each adapter transmits
network data collected via its InSight Port and conveys it over its Ethernet connection to InSight
Desktop. It also picks up any messages or new software that is addressed to this Breakout Board.
The InSight Port is a cabled communication link between the ISA3 and the EM35x Module mounted on the
Breakout Board.
•
InSight Port Cables connect each ISA3 to a Breakout Board.
•
AAA Battery Packs that attach to a Breakout Board enable deployment of battery-operated nodes.
•
USB Power Supply with Adapters power Breakout Boards and / or ISA3s from wall sockets.
•
Ethernet Cables connect ISA3s to an Ethernet subnet.
•
Data Emulation Interface (DEI) cables provide a peripheral interface connection between the ISA3 and
Breakout Board. The DEI cable supports UART functionality.

Software
The EM35x Series Development Kit contains the following software components:
•
Network Stack
•
Hardware Abstraction Layer
•
Sample Applications
•
InSight Desktop
3.4.1 Network Stack
The EmberZNet PRO network stack is an advanced implementation of the ZigBee Pro wireless protocol stack
which provides mesh routing algorithms for creating reliable, flexible, and secure networks. The stack’s APS
layer provides interfaces for delivering messages reliably. The network stack API is documented in documents
120-3009-000, Advanced Application Programming with the Stack and HAL APIs, and 120-3009-000, the EZSP
Reference Guide, as well as 120-3022-000, EmberZNet API Reference: For the EM35x SoC Platform, also
available in HTML.
The network stack is delivered as a collection of libraries that you can link to your applications. The libraries
are available in both release and debug build versions:
•
Debug build implements features that facilitate application debugging, such as error checking and an
interface to InSight Desktop, which provides information about traffic flow, API traces, error
conditions, and more.
•
Release build omits debugging functionality, so it is smaller and runs more efficiently. Use this build in
your application after it is fully debugged and ready for product release.
EM35x Development Kit User Guide
120-4030-000E
3-8
•
Stub library is a library used for resolving references but which has no functionality. For those libraries
which are not needed by the application, the stub library must be linked in order for the stack to build
properly.
Table 3-2 lists the EmberZNet PRO stack and associated libraries.
Note:
Table 3-2 shows the base library name, but it does not duplicate entries for the debug and stub
libraries because they are self explanatory.

3.4.2 Hardware Abstraction Layer
The hardware abstraction layer (HAL) acts as a conduit between the network stack and the node processor and
radio. Separating network stack functionality from the specific hardware implementation enables easy
portability. HAL code is provided as a library that you can alter in order to customize, extend, or reduce device
functionality across various hardware platforms. The HAL API is documented in document 120-3022-000, the
EmberZNet API Reference: For the EM35x SoC Platform.
3.4.3 Sample Applications
The EM35x Series Development Kit contains sample applications. These demonstrate aspects of the network
stack that show the breadth of stack functionality. Silicon Labs provides an IAR project and workspace file for
each application. Table 3-3 lists the sample applications that are in the current distribution. All applications are
in the app directory.

Breakout Board Power Configurations
The Breakout Board may be powered in one of four ways:
•
Breakout Board Power Supplied by ISA3 (Figure 4-2): The default configuration is to supply power via
the InSight Adapter and InSight Port cable. Ensure the power switch on the InSight Adapter is in the
INT (Internal) position. The power supply of the InSight Adapter is also controlled via the admin
interface. You may need to connect to the admin port of the ISA and issue the “power on” command.
No external power supply should be connected to the Breakout Board when supplying power from the
ISA. The power supply jumper on the Breakout Board should be in the horizontal position, connecting
V_ISA to the center pin. The V_ISA LED will illuminate when power is applied.
Figure 4-2. Breakout Board Power Supplied by ISA3
•
Breakout Board Power Supplied by USB (Figure 4-3): The Breakout Board may also be powered via the
USB connector, either using a USB cable plugged in to the USB power adapter included in the
development kit, or by connecting it to your PC. The power supply jumper on the Breakout Board
should be in the lower vertical position, connecting V_REG to the center pin. The V_USB LED will
illuminate when power is applied. When powering the Breakout Board in this way, ensure the power
switch on the InSight Adapter is in the EXT (External) position.

Breakout Board Serial Configurations
Serial connectivity to the Breakout Board can be made in a number of ways. The default configuration of your
development kit will match your expected usage scenario.
1.
To use the pass-through UART feature of the ISA: plug the larger 12-pin DEI cable into the DEI header on
the Breakout Board and the connector on the ISA. Ensure that jumpers are installed across the 8th (PB2) and
10th (PB1) rows of headers next to the DEI port on the Breakout Board to pass the UART RX and TX signals
through. The serial port selection jumpers between the USB and DB-9 connectors should be removed, or
placed on their center pins. Connection to the UART pass-through port can then be made using either of
the two options below:
a.
b.
Connect to the ISA using InSight Desktop. Launch the console. Choose the Serial 1 tab.
Run a terminal application (for example, Microsoft Telnet Client, HyperTerminal, PuTTY). Connect
to port 4901 on the ISA.
2.
To use the RS-232 interface: connect a serial cable to the DB-9 connector on the Breakout Board. Ensure
the 4 jumpers above the DB-9 connector are positioned towards the DB-9 connector to send the UART
signals to the RS-232 transceiver, and remove the jumpers from the row of headers next to the DEI port or
make sure the DEI cable is disconnected.
3.
To use the USB interface: install the FTDI USB drivers as described in Section 5.5, “Installing FTDI USB
Drivers”, and connect a USB cable to the Breakout Board and your PC. Ensure the four jumpers above the
DB-9 connector are positioned towards the USB connector to send the UART signals to the FTDI chip, and
remove the jumpers from the row of headers next to the DEI port or make sure the DEI cable is
disconnected.

Using the InSight Adapter
6.1
Overview
The InSight Adapter (ISA3) provides an Ethernet connection to EM35x devices. You can use the InSight Adapter to
perform the following tasks:
•
Program and debug using Serial Wire or JTAG.
•
Monitor packets sent and received by the radio.
•
Send and receive serial port data.
•
Send and receive debugging data.
•
Turn power on and off.
•
Control reset, bootloader and GPIO signals.
6.2
Connectivity and Power
All the features of the InSight Adapter are available via the Ethernet connection. The ISA3 can also be
connected to a PC via USB to change the Ethernet settings.
When connected via USB, the InSight Adapter will also be powered via USB. It should be connected to a powered
USB hub, or port on your PC that is capable of supplying full power to connected devices.
When connected via Ethernet, the InSight Adapter may be powered in one of two ways:
•
Using an Ethernet switch that supplies Power Over Ethernet (PoE).
•
Using a USB power supply.
The ISA3 will also supply power to the connected EM35x device when the power switch is in the INT (Internal)
position. If the connected EM35x device has its own power supply, ensure the power switch is kept in the EXT
(External) position.
You can connect via Ethernet to the ports listed in Table 6-1 using either InSight Desktop or a terminal
application (for example, Microsoft Telnet Client, HyperTerminal, or PuTTY).

6.3
Ethernet Settings
By default, InSight Adapters are configured to get an IP address via DHCP. They are assigned hostnames of EMISA3-00, EM-ISA3-01, etc. You can use InSight Desktop to discover the ISA3s on the network and see their IP
addresses.
EM35x Development Kit User Guide
120-4030-000E
6-2
If you are unable to use DHCP, the Ethernet configuration may be changed using the admin interface over USB
as described in “Using the admin interface over USB.” The following example changes the settings to a static IP
address of 192.168.1.100 with a netmask of 255.255.255.0 and a gateway of 192.168.1.1.
>em3xx_isa.exe --admin "ip static 192.168.1.100 255.255.255.0 192.168.1.1"
em3xx_isa version 1.0.9
DLL version 1.0.13, compiled Aug 19 2009 19:42:00
Success: ip: (after reboot) Static 192.168.1.100 255.255.255.0 192.168.1.1
>em3xx_isa.exe --admin "ip dhcp off"
em3xx_isa version 1.0.9
DLL version 1.0.13, compiled Aug 19 2009 19:42:00
Success: ip: (after reboot) DHCP off
You can change the hostname to make it more descriptive or to avoid conflicts if ISA3s from multiple
development kits are connected to the same network. To change the hostname, use the admin command
hostname set <hostname>.
6.4
Using the Admin Interface over USB
1.
Connect the ISA3 to the PC using USB. Only connect one ISA at a time by USB.
2.
Run em3xx_isa.exe with the --admin option.
3.
Configure the ISA3 using the commands described in Chapter 7, InSight Adapter Commands.
6.5
Using the Admin Interface over Ethernet
1.
Connect the ISA3 to the network using Ethernet.
2.

•
Connect to the ISA3 using InSight Desktop. Launch the console. Choose the Admin tab
OR
•
3.
6.6
Run a terminal application (e.g. Microsoft Telnet Client, HyperTerminal, PuTTY). Connect to port
4902 or 23 on the ISA3.
Configure the ISA3 using the commands described in Chapter 7, InSight Adapter Commands.
Using the Serial Ports
Connect to port 4900 or 4901 on the InSight Adapter using either InSight Desktop or a terminal application.
Port 4900 connects to the virtual serial port on the EM35x via the InSight Port cable. The virtual serial port has
no baud rate or other settings.
Port 4901 connects to the physical serial port on the EM35x via the Data Emulation Interface (DEI) cable. The
default settings are 115200 baud, 8-n-1 (8 data bits, no parity bit, 1 stop bit). To change the default settings,
use the port admin command. For example, for 19200 baud, 8-n-1, use the command port 1 19200 8-n-1.
6.7
Updating the Firmware
Periodically, Silicon Labs provides updated firmware for the InSight Adapter. You can perform the update using
em3xx_isa.exe or em3xx_load.exe. Both utilities automatically update the firmware to the latest version each
time they run.

Software Tools Overview
8.1
Using the EM357 Nodetest Application
The Nodetest Application replaces the Rangetest Application provided with earlier releases. This new
application supports a more advanced command parser and provides results in a more consistent, easy to parse
format.
The Nodetest application is pre-programmed on to the Radio Communication Modules (RCMs) included with your
EM35x Development Kit. The pre-built application image is also located at {stack installation
directory}\app\nodetest\nodetest.s37.
You may communicate with the serial interface of the Nodetest application using the methods described in
Chapter 6. Ensure that the serial port is configured for 115200 baud, 8 data bits, No parity, and 1 stop bit. By
default the InSight Adapter (ISA3) is configured in this way, but it can be adjusted in this manner:
•
Connect to the admin interface of the ISA3.
•
Issue the baud rate configuration comment for the pass-through UART (port 1): port 1 115200
The Nodetest application provides on-line help about the available commands that can be viewed by executing
the command “help”. All input parameters to Nodetest are specified in hexadecimal.
8.2
Running a Packet Error Test
A typical usage scenario for the Nodetest application is measurement of Packet Error Rate (PER). PER is defined
in 802.15.4 as the percentage of transmitted packets that are not detected correctly. The Nodetest application
provides two commands "rx" and "tx" that are designed to interoperate with the "receive" and "transmit"
commands from the EM250 Rangetest application.
PER measurement procedure:
1.
Load the Nodetest application on two EM357 nodes.
2.
Set the radio to the desired channel on both nodes with the "setchannel n" command where "n" is the
desired channel number in hex.
3.
Issue the "rx" command on the first node.
4.
Issue the "tx a" command on the second node. (This command will transmit 10 (hex a) packets of the
form required for PER analysis. For actual PER analysis, send 1000 or more packets.)
5.
Observe the PER result in the third column of the "rx" command output, for example 1:
> rx
{{(rx)} test start ('e'nd)}
#{{(rx)}

To end the rx test, press the 'e' key. To reset the rx test statistics, end and restart the rx test.
The test may also be run between an EM357 and an EM250 using the Rangetest application on the EM250. When
using Rangetest, the commands names are "receive" and "transmit."

Testing Deep Sleep Current
•
Deep sleep current can be easily measured using the Nodetest application running on a Breakout Board.
Deep sleep current can only be measured when power is supplied to the board from a source other than the
ISA3. The buffer logic on the ISA3 consumes extra current which will not allow for accurate measurements.
•
If an ISA3 is connected to the Breakout Board, then the ISA3's Target Power Select Switch should be
switched to EXT (External) so that the ISA3 is not supplying power.
•
Supply power through the USB jack, the DC jack, or the AAA Battery Pack. (The USB jack is recommended
and reviewed in these test steps because it is the simplest.)
•
Rotate the VIN_SELECTOR jumper (J2/J3) on the Breakout Board to the V_REG position (pins 2 and 3). If
power is supplied properly and all four power/LED jumpers (J2/J3, J4, J6, and J7) in the upper left corner
of the board are installed, then only the red V_USB LED and the green V_MOD LED will be illuminated.
•
To properly measure current, remove the V_MOD jumper (J6) from the Breakout Board. This ensures that
the green V_MOD LED is not being driven. If supplying voltage through the J8 battery connector, also
remove J7 so the V_BATT LED DS5 is not driven.
•
Remove the V_MOD_EN jumper (J4) from the Breakout Board to take current measurements. Then, connect
an ammeter in place of the jumper.
•
If using EM35x Breakout Board revision B0 or later, remove the DataFlash jumpers at J33 to isolate the
DataFlash IC from the rest of the circuit.

•
Once the node is asleep, disconnect the InSight Port cable, the DEI cable, the RS232 cable, and remove all
four UART jumpers (J22, J24, J25, and J26) from the Breakout Board between the USB and RS232
connectors to obtain the lowest current settings. All other jumpers may remain installed.
•
Waking up is accomplished via either activity on the SerialWire debugger or pressing BUTTON0 or BUTTON1.
To measure deep sleep while the InSight Port cable is still attached, issue the "swjdisable 1" command in
Nodetest to disable the SerialWire/JTAG port, and place the SWJ pins in a low current state. While the SWJ is
disabled, the InSight Port/debugger will not be functional until either the command "swjdisable 0" is issued or
the chip resets.

Example of Opening, Building, and Programming a Sample
Application
Follow these steps to open, build, and program the sink example application from the standard Ember installer
directory.
8.5
1.
Open the sink.eww file (sink workspace) in IAR Embedded Workbench for ARM (IAR). This can be done
by either double clicking the file C:\Program
Files\Ember\EmberZNet4.0.0\em35x\app\sensor\ewb\sink.eww or from inside of IAR using File > Open >
Workspace and navigating to the sink.eww file.
2.
Select Project > Make (F7) from inside of IAR.
3.
After making the project, the s37 file used for programming is found at C:\Program
Files\Ember\EmberZNet4.0.0\em35x\build\sink-cortexm3-iar-em357-em350-dev0680\sink.s37
4.
To program this file to the node, connect your ISA3 to the chip and your computer (this example
assumes the ISA3 is connected via USB. See the next section for how to program if the ISA3 is
connected via Ethernet.)
5.
Open a command line of your choice (such as DOS or cygwin).
6.
Navigate to the directory C:\Program Files\Ember\EmberZNet4.0.0\em35x.
7.
Invoke the command "em3xx_load.exe" without any build options. This will ensure that
em3xx_load.exe can be found in your path and will cause em3xx_load.exe to print its on-line help
menu.
8.
To download the s37 file to the EM357 chip, from the tool directory invoke the command
"em3xx_load.exe ../build/sink-cortexm3-iar-em357-em350-dev0680/sink.s37".
9.
Download will complete when em3xx_load prints the string "Run (by toggling nRESET)".
Programming your Application on the EM357
Programming EM357 flash is accomplished with the em3xx_load.exe utility. The em3xx_load utility is included as
part of the ISA3 Utilities Installer, in the “bin” subdirectory. Note that em3xx_load is not directly compatible
with the options used by em2xx_load for the EM250 platform.
A complete summary of em3xx_load functionality with brief descriptions of each option can be found in
em3xx_load's own help menu. Invoking "em3xx_load.exe" without options or invoking "em3xx_load.exe --help"
will print this help menu.
The most common usage of em3xx_load is to simply program flash. em3xx_load takes the S37 specific version of
Motorola S-record file formats; which are files with the .s37 extension. If you are using a bootloader,
em3xx_load can also load an .ebl file.
Given an S37 file called "file.s37", the most basic command for programming flash is simply:
em3xx_load.exe file.s37
Em3xx_load will then print out the versions it is using, the devices it is connected to, the steps it is performing,
and programming progress. By default, the last step em3xx_load performs is to run the chip by toggling the
nRESET pin.
By default, em3xx_load.exe assumes the InSight Adapter is connected via USB when no other options are given.
If the ISA3 is connected via Ethernet, use the --ip option to specify the ip address or hostname of the ISA3 to be
used. Given an ISA3 with an IP address of 123.123.123.123, programming can be accomplished with the
command:
em3XX_load.exe --ip 123.123.123.123 file.s37

Programming Manufacturing Tokens
The em3xx_load utility has the ability to program manufacturing tokens much like the em2xx_patch tool did. In
the case of the EM357, these tokens are contained in the Customer Information Block(CIB). For more
information on using the em3xx_load utility, refer to document 120-4032-000, EM3xx Utilities Guide.
8.6.1 Programming Certificates & Installation Codes
Certificates and installation codes can be programmed using the same em3xx_load tool that is used to program
other tokens. There is a separate application note which describes the process in detail. For more information,
see document 120-5058-000, Setting Manufacturing Certificates and Installation Codes.
8.7
Using the Debugger in IAR Embedded Workbench with an Ember
InSight Adapter
1.
Start IAR Embedded Workbench. Open the workspace (*.eww).
2.
Select Project > Options. Select the Debugger > J-Link/J-Trace category. Select the Connection tab.
3.
Select TCP/IP Communication and enter the IP address of the ISA3. Click OK.
4.
Embedded Workbench is not able to program the flash on the EM357. Every time the project is rebuilt, you must manually load it onto the EM357 (using em3xx_load.exe) before starting a debug
session.
5.
Once the correct image has been loaded onto the EM357, select Project > Debug without Downloading
to start the debug session.
