Xplained Pro
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The
platform consists of a series of Microcontroller (MCU) boards and extension boards, which are integrated
with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data
streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards,
which are connected through a set of standardized headers and connectors. Each extension board has
an identification (ID) chip to uniquely identify which boards are connected to an Xplained Pro MCU board.
This information is used to present relevant user guides, application notes, datasheets, and example
code through Atmel Studio.
3.1.
Embedded Debugger
The SAM G55 Xplained Pro contains the Atmel Embedded Debugger (EDBG) for on-board debugging.
The EDBG is a composite USB device of three interfaces; a debugger, Virtual COM Port, and a Data
Gateway Interface (DGI).
Together with Atmel Studio, the EDBG debugger interface can program and debug the ATSAMG55J19.
On SAM G55 Xplained Pro, the SWD interface is connected between the EDBG and the ATSAMG55J19.
The Virtual COM Port is connected to a UART on the ATSAMG55J19 and provides an easy way to
communicate with the target application through terminal software. It offers variable baud rate, parity, and
stop bit settings. Note that the settings on the ATSAMG55J19 must match the settings given in the
terminal software.
Info:ꢀ The virtual COM port in the EDBG requires the terminal software to set the data terminal
ready (DTR) signal to enable the UART pins connected to the ATSAMG55J19. If the DTR signal
is not enabled the UART pins on the EDBG is kept in high-z (tristate) rendering the COM port
unusable. The DTR signal is set automatically by some terminal software, but it may have to be
manually enabled in your terminal.
The DGI consists of several physical interfaces for communication with the host computer.
Communication over the interfaces is bidirectional. It can be used to send events and values from the
ATSAMG55J19 or as a generic printf-style data channel. Traffic over the interfaces can be timestamped
on the EDBG for more accurate tracing of events. Note that timestamping imposes an overhead that
reduces maximal throughput. Atmel Data Visualizer is used to send and receive data through DGI.
The EDBG controls two LEDs on SAM G55 Xplained Pro; a power LED and a status LED. The table
below shows how the LEDs are controlled in different operation modes.

For further documentation on the EDBG, see the EDBG User Guide.
3.2.
Hardware Identification System
All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication™ chip
mounted. This chip contains information that identifies the extension with its name and some extra data.
When an Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and
sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information,
code examples, and links to relevant documents. The table below shows the data fields stored in the ID
chip with example content.

Four GPIO lines are connected to the Embedded Debugger. The EDBG can monitor these lines and time
stamp pin value changes. This enables to accurately time stamp events in the SAM G55 application code.
For further information about configuring and using the GPIO monitoring features see the EDBG user
guide.

Chip Erase Jumper
When this jumper is placed on the CHIPERASE header the SAM G55 performs a chip erase after the
next power toggle of the board. For normal operation, this jumper should be placed such that only one of
the pins of the CHIPERASE header is connected and no contact is made between the two pins.

Getting Started with IAR
IAR Embedded Workbench® for ARM® is a proprietary high efficiency compiler not based on GCC.
Programming and debugging of Xplained Pro kits are supported in IAR™ Embedded Workbench for ARM
using the common CMSIS-DAP interface. Some initial settings have to be set up in the project to get the
programming and debugging to work.
The following steps will explain how to get your project ready for programming and debugging:
1. Make sure you have opened the project you want to configure. Open the OPTIONS dialog for the
project.
2. In the category General Options, select the Target tab. Select the device for the project or, if not
listed, the core of the device.
3. In the category Debugger, select the Setup tab. Select CMSIS DAP as the driver.
4. In the category Debugger, select the Download tab. Check the check box for Use flash loader(s)
option.
5. In the category Debugger > CMSIS DAP, select the Setup tab. Select System (default) as the
reset method.
6. In the category Debugger > CMSIS DAP, select the JTAG/SWD tab. Select SWD as the interface
and optionally select the SWD speed.

Connecting a SAM-ICE to an Xplained Pro Board
Xplained Pro kits featuring a 10-pin 50mil debug connector can use external debug tools like SAM-ICE™
or Atmel-ICE instead of the built-in EDBG. Devices using SWD interface on-board will have a connector
with the pinout compatible with the Cortex Debug Connector.
You can connect the SAM-ICE to the debug connector on an Xplained Pro using either an Atmel-ICE
adapter, SAM-ICE adapter, or a 10-pin 50-mil header to squid cable. When using a squid cable, see the
table and figures below for how to connect the SAM-ICE to the Xplained Pro board.

Important:ꢀ
If contention with the on-board EDBG occur, power the Xplained Pro board from another input
like the external power header or from the target USB. Physically removing the connection
between the EDBG and the debug header by removing 0Ω resistors, where available, or cutting
the tracks to the EDBG can also be done.

Hardware Revision History and Known Issues
6.1.
Identifying Product ID and Revision
The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel
Studio or by looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information
window will pop up. The first six digits of the serial number, which is listed under kit details, contain the
product identifier and revision. Information about connected Xplained Pro extension boards will also
appear in the Atmel Kit's window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the
identifier and revision in plain text as A09-nnnn\rr, where nnnn is the identifier and rr is the revision.
Boards with limited space have a sticker with only a QR-code, which contains a serial number string.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The product identifier for SAM G55 Xplained Pro is A09-2393.
6.2.
Revision 3
Revision 3 of SAM G55 Xplained Pro is the initial released version, there are no known issues.
