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:

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.

|
||||||
|
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.

|
||||||
|
|
||||||
|
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.

/* 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.
|

||||||
|
* 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.

|
* 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.
