This README file discusses the port of NuttX to the Atmel SAM E70 Xplained
Evaluation Kit (SAME70-XPLD). This board features the ATSAMV70Q21 Cortex-M7
Evaluation Kit (ATSAME70-XPLD). This board features the ATSAME70Q21 Cortex-M7

LEDs

There are two yellow LED available on the SAM E70 Xplained board that can be
turned on and off. The LEDs can be activated by driving the connected I/O
line to GND.

------ ----------- ---------------------
A single LED is available driven by PC8.
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:

LED_HEAPALLOCATE Heap has been allocated OFF OFF

be used by other board-specific logic.
Buttons
-------
SAM E70 Xplained contains three mechanical buttons. One button is the RESET
button connected to the SAM E70 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 E70 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 E70 datasheet.

so it is necessary to enable the internal pull-up in the SAM E70 to use the
