+OLED
+^^^^
+
+  The Evaluation Kit includes an OLED graphics display. Features:
+
+  - RiT P14201 series display
+  - 128 columns by 96 rows
+  - 4-bit, 16-level gray scale.
+  - High-contrast (typ. 500:1)
+  - Excellent brightness (120 cd/m2)
+  - Fast 10 us response.
+
+  The OLED display has a built-in controller IC with synchronous serial and
+  parallel interfaces (SSD1329). Synchronous serial (SSI) is used on the EVB.
+  The SSI port is shared with the microSD card slot.
+
+  - PC7: OLED display data/control select (D/Cn)
+  - PA3: OLED display chip select (CSn)
+
+  NOTE:  Newer versions of the LM3S8962 Evaluation Kit has an OSAM 128x64x4 OLED
+  display.  Some tweaks to drivers/lcd/p14201.c would be required to support that
+  LCD.
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM, you simply need to add one of the following
+  configuration options to your .config (or defconfig) file:
+
+    CONFIG_LM3S_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LM3S_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LM3S_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LM3S_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LM3S_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows) and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or Linux
+  native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had not effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.  Here are a few tip before you
+  start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lm3s,
+     arch/arm/src/common, arch/arm/src/cortexm3, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lm3s/lm3s_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lm3s8962-ek/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+USB Device Controller Functions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  Device Overview
+
+    An FT2232 device from Future Technology Devices International Ltd manages
+    USB-to-serial conversion. The FT2232 is factory configured by Luminary
+    Micro to implement a JTAG/SWD port (synchronous serial) on channel A and
+    a Virtual COM Port (VCP) on channel B. This feature allows two simultaneous
+    communications links between the host computer and the target device using
+    a single USB cable. Separate Windows drivers for each function are provided
+    on the Documentation and Software CD.
+
+  Debugging with JTAG/SWD
+
+    The FT2232 USB device performs JTAG/SWD serial operations under the control 
+    of the debugger or the Luminary Flash Programmer.  It also operate as an
+    In-Circuit Debugger Interface (ICDI), allowing debugging of any external
+    target board.  Debugging modes:
+
+    MODE DEBUG FUNCTION       USE                         SELECTED BY
+    1    Internal ICDI        Debug on-board LM3S8962     Default Mode
+                              microcontroller over USB

+    2    ICDI out to JTAG/SWD The EVB is used as a USB    Connecting to an external
+         header               to SWD/JTAG interface to    target and starting debug
+                              an external target.         software. The red Debug Out
+                                                          LED will be ON.
+    3    In from JTAG/SWD     For users who prefer an     Connecting an external
+         header               external debug interface    debugger to the JTAG/SWD
+                              (ULINK, JLINK, etc.) with   header.
+                              the EVB.
+
+  Virtual COM Port
+
+    The Virtual COM Port (VCP) allows Windows applications (such as HyperTerminal)
+    to communicate with UART0 on the LM3S8962 over USB. Once the FT2232 VCP
+    driver is installed, Windows assigns a COM port number to the VCP channel.

+Stellaris LM3S8962 Evaluation Kit Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM3=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lm3s
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_LM3S8962
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=lm3s8962-ek (for the Stellaris LM3S8962 Evaluation Kit)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_LM3S8962EK
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_DRAM_END - Last address+1 of installed RAM
+
+	   CONFIG_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
+
+	CONFIG_ARCH_IRQPRIO - The LM3S6918 supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  There are configurations for disabling support for interrupts GPIO ports.
+  GPIOJ must be disabled because it does not exist on the LM3S6918.
+  Additional interrupt support can be disabled if desired to reduce memory
+  footprint.
+
+	CONFIG_LM3S_DISABLE_GPIOA_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOB_IRQS=n

+
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is the UART0).
+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UARTn_BAUD - The configure BAUD of the UART.  Must be

+	CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UARTn_2STOP - Two stop bits
+
+	CONFIG_SSI0_DISABLE - Select to disable support for SSI0
+	CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+	CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
+	  Poll-waiting is recommended if the interrupt rate would be to
+	  high in the interrupt driven case.
+	CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
+	  emptying the Rx FIFO.  If the SPI frequency is high and this
+	  value is large, then larger values of this setting may cause
+	  Rx FIFO overrun errors.  Default: half of the Tx FIFO size (4).
+
+	CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
+	  to build the LM3S Ethernet driver
+	CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
+	CONFIG_LM3S_BOARDMAC - If the board-specific logic can provide
+	  a MAC address (via lm3s_ethernetmac()), then this should be selected.
+	CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
+	CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
+	CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding

+	CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
+	CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris LM3S8962 Evaluation Kit configuration is maintained in a
+sudirectory and can be selected as follow:
+
+	cd tools
+	./configure.sh lm3s8962-ek/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+    NOTE: As it is configured now, you MUST have a network connected.
+    Otherwise, the NSH prompt will not come up because the Ethernet
+    driver is waiting for the network to come up.  That is probably
+    a bug in the Ethernet driver behavior!
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.

+ * The external functions, lm3s_spiselect and lm3s_spistatus must be provided

+ * by board-specific logic.  The are implementations of the select and status

+ * methods SPI interface defined by struct spi_ops_s (see include/nuttx/spi.h).

+ * All othermethods (including up_spiinitialize()) are provided by common

+ * logic.  To use this common SPI logic on your board:

+ *

+ *   1. Provide lm3s_spiselect() and lm3s_spistatus() functions in your

+ *      board-specific logic.  This function will perform chip selection and

+ *      status operations using GPIOs in the way your board is configured.

+ *   2. Add a call to up_spiinitialize() in your low level initialization

+ *      logic

+ *   3. The handle returned by up_spiinitialize() may then be used to bind the

+ *      SPI driver to higher level logic (e.g., calling 

+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to

+ *      the SPI MMC/SD driver).
