See the Atmel webite for further information about this board:
- http://www.atmel.com/tools/atsamv71-xult.aspx
Serial Console
==============
The SAMV71-XULT has no on-board RS-232 drivers so it will be necessary to
use either the VCOM or an external RS-232 driver. Here are some options.
- Arduino Serial Shield: One option is to use an Arduino-compatible
serial shield. This will use the RXD and TXD signals available at pins
0 an 1, respectively, of the Arduino "Digital Low" connector. On the
SAMV71-XULT board, this corresponds to UART3:
------ ------ ------- ------- --------
Pin on SAMV71 Arduino Arduino SAMV71
J503 PIO Name Pin Function
------ ------ ------- ------- --------
1 PD28 RX0 0 URXD3
2 PD30 TX0 1 UTXD3
------ ------ ------- ------- --------
- SAMV7-XULT EXTn connectors. USART pins are also available the EXTn
connectors. The following are labelled in the User Guide for USART
functionality:
---- -------- ------ --------
EXT1 EXTI1 SAMV71 SAMV71
Pin Name PIO Function
---- -------- ------ --------
13 USART_RX PB00 RXD0
14 USART_TX PB01 TXD0
---- -------- ------ --------
EXT2 EXTI2 SAMV71 SAMV71
Pin Name PIO Function
---- -------- ------ --------
13 USART_RX PA21 RXD1
14 USART_TX PB04 TXD1
- VCOM. The Virtual Com Port gateway is available on USART1:
------ --------
SAMV71 SAMV71
PIO Function
------ --------
PB04 TXD1
PA21 RXD1
------ --------
Any of these options can be selected as the serial console by:
1. Enabling the UART/USART peripheral in the
"System Type -> Peripheral Selection" menu, then
2. Configuring the peripheral in the "Drivers -> Serial Configuration"
menu.
LEDs and Buttons
================
LEDs
----
There are two yellow LED available on the SAM V71 Xplained Ultra board that
can be turned on and off. The LEDs can be activated by driving the
connected I/O line to GND.
------ ----------- ---------------------
SAMV71 Function Shared functionality
PIO
------ ----------- ---------------------
PA23 Yellow LED0 EDBG GPIO
PC09 Yellow LED1 LCD, and Shield
------ ----------- ---------------------
These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
include/board.h and src/sam_autoleds.c. The LEDs are used to encode
OS-related events as follows:
------------------- ----------------------- -------- --------
SYMBOL Meaning LED state
LED0 LED1
------------------- ----------------------- -------- --------
LED_STARTED NuttX has been started OFF OFF
LED_HEAPALLOCATE Heap has been allocated OFF OFF
LED_IRQSENABLED Interrupts enabled OFF OFF
LED_STACKCREATED Idle stack created ON OFF
LED_INIRQ In an interrupt No change
LED_SIGNAL In a signal handler No change
LED_ASSERTION An assertion failed No change
LED_PANIC The system has crashed N/C Blinking
LED_IDLE MCU is is sleep mode Not used
------------------- ----------------------- -------- --------
Thus if LED0 is statically on, NuttX has successfully booted and is,
apparently, running normally. If LED1 is flashing at approximately
2Hz, then a fatal error has been detected and the system has halted.
NOTE: That LED0 is not used after completion of booting and may
be used by other board-specific logic.
Buttons
-------
SAM V71 Xplained Ultra contains three mechanical buttons. One button is the
RESET button connected to the SAM V71 reset line and the others are generic
user configurable buttons. When a button is pressed it will drive the I/O
line to GND.
------ ----------- ---------------------
SAMV71 Function Shared functionality
PIO
------ ----------- ---------------------
RESET RESET Trace, Shield, and EDBG
PA09 SW0 EDBG GPIO and Camera
PB12 SW1 EDBG SWD and Chip Erase
------ ----------- ---------------------
NOTES:
- There are no pull-up resistors connected to the generic user buttons so
it is necessary to enable the internal pull-up in the SAM V71 to use the
button.
- PB12 is set up as a system flash ERASE pin when the firmware boots. To
use the SW1, PB12 has to be configured as a normal regular I/O pin in
the MATRIX module. For more information see the SAM V71 datasheet.

/* Buttons
* To be provided
*
* SAM V71 Xplained Ultra contains three mechanical buttons. One button is the
* RESET button connected to the SAM V71 reset line and the others are generic
* user configurable buttons. When a button is pressed it will drive the I/O
* line to GND.

* PB12 SW1 EDBG SWD and Chip Erase
* ------ ----------- ---------------------
*
* NOTES:
*
* - There are no pull-up resistors connected to the generic user buttons so
* it is necessary to enable the internal pull-up in the SAM V71 to use the
* button.
* - PB12 is set up as a system flash ERASE pin when the firmware boots. To
* use the SW1, PB12 has to be configured as a normal regular I/O pin in
* the MATRIX module. For more information see the SAM V71 datasheet.
