configuration options for SAMA5 external memory regions; add a custom
sam_allocateheap.c to add the various configured memory regions to the

configuration logic for USARTs needs to depend on if the USART is
configured as a UART or not. And this is for all CPUS, not just
SAM3/4 (2013-7-24).

@ -230,16 +286,99 @@ Buttons and LEDs
Buttons
-------
To be provided
There are five push button switches on the SAMA5D3X-EK base board:
1. One Reset, board reset (BP1)
2. One Wake up, push button to bring the processor out of low power mode
(BP2)
3. One User momentary Push Button
4. One Disable CS Push Button
Only the momentary push button is controllable by software (labeled
"PB_USER1" on the board):
- PE27. Pressing the switch connect PE27 to grounded. Therefore, PE27
must be pulled high internally. When the button is pressed the SAMA5
will sense "0" is on PE27.
LEDs
----
To be provided
There are two LEDs on the SAMA5D3 series-CM board that can be controlled
by software. A blue LED is controlled via GPIO pins. A red LED normally
provides an indication that power is supplied to the board but can also
be controlled via software.
PE25. This blue LED is pulled high and is illuminated by pulling PE25
low.
PE24. The red LED is also pulled high but is driven by a transistor so
that it is illuminated when power is applied even if PE24 is not
configured as an output. If PE24 is configured as an output, then the
LCD is illuminated by a low output.
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_leds.c. The LEDs are used to encode OS-related
events as follows:
SYMBOL Meaning LED state
Blue Red
------------------- ----------------------- -------- --------
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 OFF Blinking
LED_IDLE MCU is is sleep mode Not used
Thus if the blue LED is statically on, NuttX has successfully booted and
is, apparently, running normmally. If the red is flashing at
approximately 2Hz, then a fatal error has been detected and the system
has halted.
Serial Consoles
===============
To be provided
USART1
------
By default USART1 is used as the NuttX serial console in all
configurations (unless otherwise noted). USART1 is buffered with an
RS-232 Transceiver (Analog Devices ADM3312EARU) and connected to the DB-9
male socket (J8).

PB29 TXD1 GPIO_USART1_TXD
PB28 RXD1 GPIO_USART1_RXD
PB26 CTS1 GPIO_USART1_CTS
NOTE: Debug TX and RX pins also go the the ADM3312EARU, but I am
uncertain of the functionality.

Hardware UART via CDC
---------------------
"J-Link-OB-ATSAM3U4C comes with an additional hardware UART that is
accessible from a host via CDC which allows terminal communication with
the target device. This feature is enabled only if a certain port (CDC
disabled, PA25, pin 24 on J-Link-OB-ATSAM3U4C) is NOT connected to ground
(open).
- Jumper JP16 not fitted: CDC is enabled
- Jumper JP16 fitted : CDC is disabled"

ostest:
This configuration directory, performs a simple OS test using
examples/ostest.
NOTES:
1. This configuration uses the default USART1 serial console. That
is easily changed by reconfiguring to (1) enable a different
serial peripheral, and (2) selecting that serial peripheral as
the console device.
2. By default, this configuration is set up to build on Windows
under either a Cygwin or MSYS environment using a recent, Windows-
native, generic ARM EABI GCC toolchain (such as the CodeSourcery
toolchain). Both the build environment and the toolchain
selection can easily be changed by reconfiguring:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
3. This configuration executes out of internal SRAM an can only
be loaded via JTAG.
CONFIG_SAMA5_BOOT_ISRAM=y : Boot into internal SRAM
CONFIG_BOOT_RUNFROMISRAM=y : Run from internal SRAM
