System Clock
============
The SAMD21 MCU is configured to use the 32.768 kHz external oscillator
with the on-chip PLL generating the 48 MHz system clock.
Serial Port
===========
The SAMD21 MCU has six SERCOM based USARTs with three configured as USARTs in
this BSP. SERCOM3 is the default Zephyr console.
- SERCOM0 9600 8n1
- SERCOM1 115200 8n1
- SERCOM3 115200 8n1 connected to the onboard Atmel Embedded Debugger (EDBG)
PWM
===
The SAMD21 MCU has 3 TCC based PWM units with up to 4 outputs each and a period
of 24 bits or 16 bits. If :code:`CONFIG_PWM_SAM0_TCC` is enabled then LED0 is
driven by TCC0 instead of by GPIO.
SPI Port
========
The SAMD21 MCU has 6 SERCOM based SPIs. On the SAM D21 Xplained Pro,
SERCOM5 is connected to an 8 megabit SPI flash.
Programming and Debugging
*************************
The SAM D21 Xplained Pro comes with a Atmel Embedded Debugger (EDBG). This
provides a debug interface to the SAMD21 chip and is supported by
OpenOCD.
Flashing
========
#. Build the Zephyr kernel and the ``hello_world`` sample application:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: samd21_xpro
:goals: build
:compact:
#. Connect the SAM D21 Xplained Pro to your host computer using the USB debug
port.
#. Run your favorite terminal program to listen for output. Under Linux the
terminal should be :code:`/dev/ttyACM0`. For example:
.. code-block:: console
$ minicom -D /dev/ttyACM0 -o
The -o option tells minicom not to send the modem initialization
string. Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
#. To flash an image:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: samd21_xpro
:goals: flash
:compact:
You should see "Hello World! samd21_xpro" in your terminal.

SAM R21 Xplained Pro Evaluation Kit
###################################
Overview
********
The SAM R21 Xplained Pro is a compact evaluation board by Atmel featuring a
SAMR21G18A SoC. The SoC includes a SAMR21 ARM Cortex-M0+ micro-controller
bundled with Atmel's AT86RF233, a 2.4GHz IEEE802.15.4 compatible radio.
The kit includes Atmels Embedded Debugger (EDBG), which provides a full
debug interface without the need for additional hardware.

Supported Features
==================
The samr21_xpro board configuration supports the following hardware
features:
+-----------+------------+--------------------------------------+
| Interface | Controller | Driver/Component |
+===========+============+======================================+
| NVIC | on-chip | nested vector interrupt controller |
+-----------+------------+--------------------------------------+
| SYSTICK | on-chip | systick |
+-----------+------------+--------------------------------------+
| WDT | on-chip | Watchdog |
+-----------+------------+--------------------------------------+
| GPIO | on-chip | I/O ports |
+-----------+------------+--------------------------------------+
| PWM | on-chip | Pulse Width Modulation |
+-----------+------------+--------------------------------------+
| USART | on-chip | Serial ports |
+-----------+------------+--------------------------------------+
| SPI | on-chip | Serial Peripheral Interface ports |
+-----------+------------+--------------------------------------+
| I2C | on-chip | I2C Peripheral Interface ports |
+-----------+------------+--------------------------------------+
Other hardware features are not currently supported by Zephyr.
The default configuration can be found in the Kconfig
:zephyr_file:`boards/atmel/sam0/samr21_xpro/samr21_xpro_defconfig`.
Pin Mapping
===========
The SAM R21 Xplained Pro evaluation kit has 3 GPIO controllers. These
controllers are responsible for pin muxing, input/output, pull-up, etc.
For more details please refer to `SAM R21 Family Datasheet`_ and the `SAM R21
Xplained Pro Schematic`_.
.. image:: img/ATSAMR21-XPRO-pinout.jpg
:align: center
:alt: SAMR21-XPRO-pinout
Default Zephyr Peripheral Mapping:
----------------------------------
- SERCOM0 USART TX : PA5
- SERCOM0 USART RX : PA4
- SERCOM1 I2C SDA : PA16
- SERCOM1 I2C SCL : PA17
- SERCOM5 SPI MISO : PB02
- SERCOM5 SPI MOSI : PB22
- SERCOM5 SPI SCK : PB23
- GPIO SPI CS : PB03
- GPIO/PWM LED0 : PA19
System Clock
============
The SAMR21 MCU is configured to use the 32.768 kHz external oscillator
with the on-chip PLL generating the 48 MHz system clock.
Serial Port
===========
The SAMR21 MCU has six SERCOM based USARTs with two configured as USARTs in
this BSP. SERCOM0 is the default Zephyr console.
- SERCOM0 115200 8n1 connected to the onboard Atmel Embedded Debugger (EDBG)
PWM
===
The SAMR21 MCU has 3 TCC based PWM units with up to 4 outputs each and a
period of 24 bits or 16 bits. If :code:`CONFIG_PWM_SAM0_TCC` is enabled then
LED0 is driven by TCC0 instead of by GPIO.
SPI Port
========
The SAMR21 MCU has 6 SERCOM based SPIs.
- SERCOM5 is exposed via Xplained Pro Standard Extension Header
I2C Port
========
When connecting an I2C device and a logic analyzer to an I2C port at the same
time, the internal pull-up resistors are not sufficient for stable bus
operation. You probably have to connect external pull-ups to both bus lines. 10K
is a good value to start with.
- SERCOM1 is exposed via Xplained Pro Standard Extension Header
Radio
=====
The SAMR21 SoC includes an on-chip AT86RF233 radio. It is internally
connected via SPI and some GPIO pins and behaves the same way as
externally connected SPI devices.

Zephyr provide several samples that can use this technology. You can check
:zephyr:code-sample:`wpan-serial` example as starting points.
Another good test can be done with IPv6 by using the server/client
echo demo. More information at :zephyr:code-sample:`sockets-echo-server` and
:zephyr:code-sample:`sockets-echo-client`.
Programming and Debugging
*************************
The SAM R21 Xplained Pro comes with a Atmel Embedded Debugger (EDBG). This
provides a debug interface to the SAMR21 chip and is supported by
OpenOCD.
Flashing
========
#. Build the Zephyr kernel and the :ref:`hello_world` sample application:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: samr21_xpro
:goals: build
:compact:
#. Connect the SAM R21 Xplained Pro to your host computer using the USB debug
port.
#. Run your favorite terminal program to listen for output. Under Linux the
terminal should be :code:`/dev/ttyACM0`. For example:
.. code-block:: console
$ minicom -D /dev/ttyACM0 -o
The -o option tells minicom not to send the modem initialization
string. Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
#. To flash an image:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: samr21_xpro
:goals: flash
:compact:
You should see "Hello World! samr21_xpro" in your terminal.

- SERCOM0 - connected to EXT1
- SERCOM5 - connected to EXT2 and EXT3
Programming and Debugging
*************************
The SAM L21 Xplained Pro comes with a Atmel Embedded Debugger (EDBG). This
provides a debug interface to the SAML21 chip and is supported by
OpenOCD.
Flashing
========
#. Build the Zephyr kernel and the ``hello_world`` sample application:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: saml21_xpro
:goals: build
:compact:
#. Connect the SAM L21 Xplained Pro to your host computer using the USB debug
port.
#. Run your favorite terminal program to listen for output. Under Linux the
terminal should be :code:`/dev/ttyACM0`. For example:
.. code-block:: console
$ picocom -b 115200 /dev/ttyACM0
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
#. To flash an image:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: saml21_xpro
:goals: flash
:compact:
You should see "Hello World! saml21_xpro" in your terminal.

with the on-chip PLL generating the 48 MHz system clock.
Serial Port
===========
The SAMD20 MCU has 6 SERCOM based USARTs. One of the USARTs
(SERCOM3) is connected to the onboard Atmel Embedded Debugger (EDBG).
SERCOM4 is available on the EXT1 connector.
SPI Port
========
The SAMD20 MCU has 6 SERCOM based SPIs. On the SAM D20 Xplained Pro,
SERCOM0 is available on the EXT1 connector.
Programming and Debugging
*************************
The SAM D20 Xplained Pro comes with a Atmel Embedded Debugger (EDBG). This
provides a debug interface to the SAMD20 chip and is supported by
OpenOCD.
Flashing
========
#. Build the Zephyr kernel and the :ref:`hello_world` sample application:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: samd20_xpro
:goals: build
:compact:
#. Connect the SAM D20 Xplained Pro to your host computer using the USB debug
port.
#. Run your favorite terminal program to listen for output. Under Linux the
terminal should be :code:`/dev/ttyACM0`. For example:
.. code-block:: console
$ minicom -D /dev/ttyACM0 -o
The -o option tells minicom not to send the modem initialization
string. Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
#. To flash an image:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: samd20_xpro
:goals: flash
:compact:
You should see "Hello World! samd20_xpro" in your terminal.

Connections and IOs
===================
The `SAM4E Xplained Pro User Guide`_ has detailed information about board
connections. Download the `SAM4E Xplained Pro documentation`_ for more detail.
System Clock
============
The SAM4E MCU is configured to use the 12 MHz internal oscillator on the board
with the on-chip PLL to generate an 120 MHz system clock.
Serial Port
===========
The ATSAM4E16E MCU has 2 UARTs and 2 USARTs. One of the UARTs (UART0) is
configured for the console and is available as a Virtual COM Port by EDBG USB
chip.
Programming and Debugging
*************************
Flashing the Zephyr project onto SAM4E MCU requires the `OpenOCD tool`_.
By default a factory new SAM4E chip will boot SAM-BA boot loader located in
the ROM, not the flashed image. This is determined by the value of GPNVM1
(General-Purpose NVM bit 1). The flash procedure will ensure that GPNVM1 is
set to 1 changing the default behavior to boot from Flash.
If your chip has a security bit GPNVM0 set you will be unable to program flash
memory or connect to it via a debug interface. The only way to clear GPNVM0
is to perform a chip erase procedure that will erase all GPNVM bits and the full
contents of the SAM4E flash memory:
- With the board power off, set a jumper on the J304 header.
- Turn the board power on. The jumper can be removed soon after the power is on
(flash erasing procedure is started when the erase line is asserted for at
least 230ms)
Flashing
========
For flash the board Zephyr provides two paths. One uses the default OpenOCD
tool and the second one uses :ref:`atmel_sam_ba_bootloader`.
Using OpenOCD
-------------
#. Connect the SAM4E Xplained Pro board to your host computer using the USB
debug port. Then build and flash the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam4e_xpro
:goals: build flash
Using SAM-BA bootloader
-----------------------
#. Close the ``ERASE`` jumper on the SAM4E Xplained Pro board. Power on the
board for 10s.
#. Open the ``ERASE`` jumper.
#. Connect the SAM4E Xplained Pro board to your host computer using the SoC
USB port. Then build and flash the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam4e_xpro
:goals: build
.. code-block:: console
$ west flash -r bossac
Visualizing the message
-----------------------
#. Run your favorite terminal program to listen for output. Under Linux the
terminal should be :code:`/dev/ttyACM0`. For example:
.. code-block:: console
$ minicom -D /dev/ttyACM0 -o
The -o option tells minicom not to send the modem initialization string.
Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
#. Press reset button
You should see "Hello World! sam4e_xpro" in your terminal.
Debugging
=========
You can debug an application in the usual way. Here is an example for the
:ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam4e_xpro
:maybe-skip-config:
:goals: debug

Other hardware features are not currently supported by Zephyr.
The default configuration can be found in the Kconfig
:zephyr_file:`boards/atmel/sam/sam_v71_xult/sam_v71_xult_samv71q21_defconfig`.
Connections and IOs
===================
The `SAMV71-XULT User Guide`_ has detailed information about board
connections.
System Clock
============
The SAM V71 MCU is configured to use the 12 MHz external oscillator on the
board with the on-chip PLL to generate a 300 MHz system clock.
Serial Port
===========
The ATSAMV71Q21 MCU has five UARTs and three USARTs. USART1 is configured
for the console and is available as a Virtual COM Port via EDBG USB chip.
Programming and Debugging
*************************
Flashing the Zephyr project onto SAM V71 MCU requires the `OpenOCD tool`_.
By default a factory new SAM V71 chip will boot the `SAM-BA`_ boot loader
located in the ROM, not the flashed image. This is determined by the value
of GPNVM1 (General-Purpose NVM bit 1). The flash procedure will ensure that
GPNVM1 is set to 1 changing the default behavior to boot from Flash.
If your chip has a security bit GPNVM0 set you will be unable to program flash
memory or connect to it via a debug interface. The only way to clear GPNVM0
is to perform a chip erase procedure that will erase all GPNVM bits and the
full contents of the SAM V71 flash memory:
- With the board power off, set a jumper on the J200 header.
- Turn the board power on. The jumper can be removed soon after the power is
on (flash erasing procedure is started when the erase line is asserted for
at least 230ms)
Flashing
========
#. Run your favorite terminal program to listen for output. Under Linux the
terminal should be :code:`/dev/ttyACM0`. For example:
.. code-block:: console
$ minicom -D /dev/ttyACM0 -o
The -o option tells minicom not to send the modem initialization
string. Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
#. Connect the SAM V71 Xplained Ultra board to your host computer using the
USB debug port. Then build and flash the :ref:`hello_world`
application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam_v71_xult/samv71q21
:goals: build flash
You should see "Hello World! sam_v71_xult" in your terminal.
#. To use the SoC variation B IC, you need type "sam_v71_xult/samv71q21b".
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam_v71_xult/samv71q21b
:goals: build flash
You should see "Hello World! sam_v71_xult" in your terminal.
You can flash the image using an external debug adapter such as J-Link
or ULINK, connected to the 20-pin JTAG header. Supply the name of the
debug adapter (e.g., ``jlink``) via an OPENOCD_INTERFACE environment
variable. OpenOCD will look for the appropriate interface
configuration in an ``interface/$(OPENOCD_INTERFACE).cfg`` file on its
internal search path.
Debugging
=========
You can debug an application in the usual way. Here is an example for the
:ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam_v71_xult/samv71q21
:maybe-skip-config:
:goals: debug

Connections and IOs
===================
Download the `SAM4S Xplained Design Files`_ for more information. It has
full schematic and gerbers files.
System Clock
============
The SAM4S MCU is configured to use the 12 MHz internal oscillator on the board
with the on-chip PLL to generate an 84 MHz system clock.
Serial Port
===========
The ATSAM4S16C MCU has 2 UARTs and 2 USARTs. One of the UARTs (UART0) is
connected to the Segger J-Link OB chip (the AT91SAM3U4 is programmed to be
Segger J-Link OB). Segger J-Link OB brings the UART out as a virtual COM port.
The section flashing uses the UART from the Segger USB debug connection.
Programming and Debugging
*************************
The SAM4S Xplained board comes with Segger
`J-Link OB <path_to_url`_. This provides a debug
interface to the SAM4S16C chip. You can use Ozone or JLink to communicate with
the SAM4S16C.
Flashing
========
For flash the board Zephyr provides two paths. One uses the default JLink
tool and the second one uses :ref:`atmel_sam_ba_bootloader`.
Using JLink
-------------
#. Download JLink from the Segger `JLink Downloads Page`_. Go to the section
"J-Link Software and Documentation Pack" and install the "J-Link Software
and Documentation pack for Linux". The application JLinkExe needs to be
accessible from your path.
#. Connect the SAM4S Xplained board to your host computer using the USB debug
port. Then build and flash the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam4s_xplained
:goals: build flash
Using SAM-BA bootloader
-----------------------
#. Close the ``J25`` jumper on the SAM4S Xplained board. Power on the board
for 10s.
#. Open the ``J25`` jumper.
#. Connect the SAM4S Xplained board to your host computer using the SoC USB
port. Then build and flash the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam4s_xplained
:goals: build
.. code-block:: console
$ west flash -r bossac
Visualizing the message
-----------------------
#. Run your favorite terminal program to listen for output. Under Linux the
terminal should be :code:`/dev/ttyACM0`. For example:
.. code-block:: console
$ minicom -D /dev/ttyACM0 -o
The -o option tells minicom not to send the modem initialization string.
Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
#. Press reset button
You should see "Hello World! sam4s_xplained" in your terminal.
Debugging
=========
You can debug an application in the usual way. Here is an example for the
:ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: sam4s_xplained
:maybe-skip-config:
:goals: debug

SAM4L-EK
########
Overview
********
The SAM4L series embeds picoPower technology for ultra-low power consumption.
Combined power control techniques are used to bring active current consumption
down to 90A/MHz. The device allows a wide range of configurations giving the
user the ability to balance between the lowest possible power consumption and
the feature set selected for the application. The WAIT and RETENTION modes
provide full logic and RAM retention, associated with fast wake-up capability
(<1.5s) and a very low consumption of, respectively, 3 A and 1.5 A. In
addition, WAIT mode supports SleepWalking features. In BACKUP mode, CPU,
peripherals and RAM are powered off consuming less than 0.9A with external
interrupt wake-up support.
The SAM4L-EK is a full featured design to develop for Atmel SAM4L SoC series.
The kit is equipped with a rich set of peripherals that make the ATSAM4L-EK a
perfect evaluation platform. Download the `SAM4L-EK Online User Guide`_ for
more details.
