+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux, Mac OS X 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 GCC on
+  Mac OS X.
+
+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).
+
+  To use a specific toolchain, 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 or on Mac OS X.
+    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 no 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.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips 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/armv7-m, 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.
+
+  This port was tested with tools built using summon-arm-toolchain; available
+  from https://github.com/esden/summon-arm-toolchain, however the buildroot
+  instructions should apply for other platforms.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lm3s6432-s2e/<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.

+
+Stellaris MDL-S2E Reference Design 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_LM3S6432
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=lm3s6432-s2e (for the Stellaris MDL-S2E Reference Design)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_LM3S6432S2E
+
+	CONFIG_ARCH_LOOPSPERMSEC - As supplied, calibrated for correct operation
+	   of delay loops assuming 50MHz CPU frequency.
+
+	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.
+  GPIOH and GPIOJ must be disabled because they do not exist on the LM3S6432.
+  Additional interrupt support can be disabled if desired to reduce memory
+  footprint - GPIOs C-G are not pinned out on the MDL-S2E board.
+
+	CONFIG_LM3S_DISABLE_GPIOA_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOB_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOC_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOD_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOE_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOF_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOG_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOH_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOJ_IRQS=y
+ 
+  LM3S6432 specific device driver settings
+
+	CONFIG_UARTn_DISABLE
+	   The TX and RX pins for UART1 share I/O pins with the TX and RX pins
+	   for SSI0.  To avoid conflicts, only one of SSI0 and UART1 should
+	   be enabled in a configuration.
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is UART1).
+	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_BITS - The number of bits.  Must be either 7 or 8.
+	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
+	  The TX and RX pins for SSI0 share I/O pins with the TX and RX pins
+	  for UART1.  To avoid conflicts, only one of SSI0 and UART1 should
+	  be enabled in a configuration.
+	CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+	  Note that the LM3S6432 only has one SSI, so SSI1 should always be
+	  disabled.
+	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 - This should be set in order to use the
+	  MAC address configured in the flash USER registers.
+	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_MULTICAST - Set to enable multicast frames
+	CONFIG_LM3S_PROMISCUOUS - Set to enable promiscuous mode
+	CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
+	CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris MDL-S2E Reference Design configuration is maintained in a
+sudirectory and can be selected as follow:
+
+	cd tools
+	./configure.sh lm3s6432-s2e/<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.
+
+    NOTE: as the configuration stands, ostest will hang during the 
+    semaphore test.  This has not been debugged.

+ * 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).
