   You must take care that the correct Cygwin DLL is used.

-^^^^

-  If you use the GCC AVR toolchain from the Atmel Studio, then you can
-  enable suppport for the MEMX storage:
-
-    CONFIG_AVR_HAS_MEMX_PTR=y
-
-  If this support is enabled, then all strings will be saved in FLASH and
-  standard string-oriented interfaces such printf() will change so that
-  they accept memx pointers.
-
-  This means that (1) ALL strings must lie in FLASH, and (2) since the
-  strings are moved from SRAM to FLASH, you will save a LOT of SRAM usage
-  in some configurations that use a lot of string memory (such as the
-  ostest and nsh configurations).

+
+  Console
+  -------
+
+  The LPC4337-ws default console is the USART2.
+
+Status
+======
+
+  This is the current status of the LPC43xx port:
+
+  - The basic OS test configuration and the basic NSH configurations
+    are present and fully verified.  This includes:  SYSTICK system time,
+    pin and GPIO configuration, and serial console support.  A SPIFI
+    MTD driver is also in place but requires further verification.
+
+  - The following drivers have been copied from the LPC17xx port, but
+    require integration into the LPC43xx.  This integration should
+    consist of:
+
+    - Remove LPC17xx power, clocking, and pin configuration logic.
+    - Adding of clock source and frequency to the board.h file.
+    - Adding of LPC43 clock connection and pin configuration logic.
+
+    Within any luck, these drivers should come up very quickly:
+
+    - lpc43_adc.c,
+    - lpc43_dac.c,
+    - lpc43_gpdma.c,
+    - lpc43_i2c.c,
+    - lpc43_spi.c, and
+    - lpc43_ssp.c
+
+    These LPC17xx drivers were not brought into the LPC43xx port because
+    it appears the these peripherals have been completely redesigned:
+
+    - CAN,
+    - Ethernet,
+    - USB device, and
+    - USB host.
+
+    The following LPC43xx peripherals are unsupported.  Some may be
+    compatible with the LPC17xx, but there is no LPC17xx driver to be
+    ported:
+
+    - SD/MMC,
+    - EMC,
+    - USB0,
+    - USB1,
+    - Ethernet,
+    - LCD,
+    - SCT,
+    - Timers 0-3
+    - MCPWM,
+    - QEI,
+    - Alarm timer,
+    - WWDT,
+    - RTC,
+    - Event monitor, and
+    - CAN,
+
+    For the missing drivers some of these can be leveraged from other
+    MCUs that appear to support the same peripheral IP.
+
+    - USB0 appears to be the same as the USB OTG peripheral for the
+      LPC31xx.  It should be possible to drop in the LPC31xx driver
+      with a small porting effort.
+
+    - The Ethernet block looks to be based on the same IP as the
+      STM32 Ethernet and, as a result, it should be possible to leverage
+      the STM32 Ethernet driver with a little more effort.
+
+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 Code Red GNU toolchain,
+  2. The CodeSourcery GNU toolchain,
+  3. The Atollic Toolchain,
+  4. The devkitARM GNU toolchain,
+  5. 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 toolchain, you simply need add one of the
+  following configuration options to your .config (or defconfig) file:
+
+    CONFIG_ARMV7M_TOOLCHAIN_CODEREDW=y       : Code Red "RedSuite" under Windows
+    CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_ARMV7M_TOOLCHAIN_ATOLLIC=y        : The Atollic toolchain under Windows
+    CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the Code Red, CodeSourcery (for Windows), Atollic and devkitARM toolchains
+  are Windows native toolchains.  The CodeSourcery (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.
+
+  The CodeSourcery Toolchain (2009q1)
+  -----------------------------------
+  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.
+
+  The Atollic "Pro" and "Lite" Toolchain
+  --------------------------------------
+  One problem that I had with the Atollic toolchains is that the provide a gcc.exe
+  and g++.exe in the same bin/ file as their ARM binaries.  If the Atollic bin/ path
+  appears in your PATH variable before /usr/bin, then you will get the wrong gcc
+  when you try to build host executables.  This will cause to strange, uninterpretable
+  errors build some host binaries in tools/ when you first make.
+
+  Also, the Atollic toolchains are the only toolchains that have built-in support for
+  the FPU in these configurations.  If you plan to use the Cortex-M4 FPU, you will
+  need to use the Atollic toolchain for now.  See the FPU section below for more
+  information.
+
+  The Atollic "Lite" Toolchain
+  ----------------------------
+  The free, "Lite" version of the Atollic toolchain does not support C++ nor
+  does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
+  toolchain, you will have to set:
+
+    CONFIG_HAVE_CXX=n
+
+  In order to compile successfully.  Otherwise, you will get errors like:
+
+    "C++ Compiler only available in TrueSTUDIO Professional"
+
+  The make may then fail in some of the post link processing because of some of
+  the other missing tools.  The Make.defs file replaces the ar and nm with
+  the default system x86 tool versions and these seem to work okay.  Disable all
+  of the following to avoid using objcopy:
+
+    CONFIG_RRLOAD_BINARY=n
+    CONFIG_INTELHEX_BINARY=n
+    CONFIG_MOTOROLA_SREC=n
+    CONFIG_RAW_BINARY=n
+
+  devkitARM
+  ---------
+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the
+  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/lpc43xx,
+     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/common/up_vectors.S.
+
+Code Red IDE/Tools
+^^^^^^^^^^^^^^^^^^
+
+  Booting the LPCLink
+  -------------------
+
+  The first step is to activate the LPCLink's boot mode.  Some general
+  instructions to do this are provided here:
+
+    http://support.code-red-tech.com/CodeRedWiki/BootingLPCLink
+
+  For my RedSuite installation path, that can be done using the following
+  steps in a Cygwin bash shell:
+
+    $ /cygdrive/c/code_red/RedSuite_4.2.3_379/redsuite/bin/Scripts/bootLPCXpresso.cmd winusb
+    Booting LPC-Link with LPCXpressoWIN.enc
+    Press any key to continue . . .
+
+  The same file logic can be found the less restrictive LPCXpresso package at:
+
+    /cygdrive/c/nxp/LPCXpresso_4.2.3_292/lpcxpresso/bin
+
+  (The "free" RedSuite version has a download limit of 8K; the "free" LPCXpresso
+  version has a download limit of 128K).
+
+  NOTE that the following alias is defined in the setenv.sh file and
+  can be used to enter the boot mode with a simpler command:
+
+    alias lpc43xx='${SCRIPT_BIN}/Scripts/bootLPCXpresso.cmd winusb'
+
+  Be default, the setenv.sh scripts uses the LPCXpresso path shown above.
+  Once setenv.sh has been sources, then entering boot mode becomes simply:
+
+    $ lpc43xx
+    Booting LPC-Link with LPCXpressoWIN.enc
+    Press any key to continue . . .
+
+  Using GDB
+  ---------
+
+  The underlying debugger within Red Suite/LPCXpresso is GDB.  That GDB
+  used from the command line.  The GDB configuration details for command
+  line use are on Code Red Wiki:
+
+    http://support.code-red-tech.com/CodeRedWiki/UsingGDB
+
+  and is also summarized here (see the full Wiki for additional details
+  and options).
+
+  The Code Red Debug Driver implements the GDB "remote" protocol to allow
+  connection to debug targets.  To start a debug session using GDB, use
+  following steps:
+
+    arm-none-eabi-gdb executable.axf                  : Start GDB and name the debug image
+    target extended-remote | <debug driver> <options> : Start debug driver, connect to target
+    load                                              : Load image and download to target
+
+  The where <debug driver> is crt_emu_lpc18_43_nxp for LPC18xx and LPC43xx.
+  Your PATH variable should be set up so that the debug driver executable
+  can be found.  For my installation, the driver for the LPC18xx and LPC43xx
+  is located at:
+
+    /cygdrive/c/code_red/RedSuite_4.2.3_379/redsuite/bin/crt_emu_lpc18_43_nxp.exe, OR
+    /cygdrive/c/nxp/LPCXpresso_4.2.3_292/lpcxpresso/bin/crt_emu_lpc18_43_nxp.exe
+
+  And <options> are:
+
+    -n set information level for the debug driver. n should be 2, 3 or 4.
+        2 should be sufficient in most circumstances
+
+    -p<part> is the target device to connect to and you should use
+        <part>=LPC4337.
+
+    -wire=<probe> specifies the debug probe.  For LPCLink on Windows 7 use
+        <probe>=winusb.  The 128K free version only supports the LPC-Link
+        and RedProbe debug probes. Other JTAG interfaces are supported in
+        the full version.
+
+  Thus the correct invocation for the LPC4337 under Windows7 would be:
+
+    target extended-remote | crt_emu_lpc18_43_nxp -2 -pLPC4337 -wire=winusb
+
+  DDD.  This command can be used to start GDB under the graphics front-end
+  DDD:
+
+    $ ddd --debugger arm-none-eabi-gdb nuttx &
+
+  NOTE 1:  Don't forget to put the LPCLink in boot mode as described above
+  before starting GDB.  So a typical session might look like this:
+
+    $ lpc43xx
+    Booting LPC-Link with LPCXpressoWIN.enc
+    Press any key to continue . . .
+
+    $ arm-none-eabi-gdb nuttx
+    (gdb) target extended-remote | crt_emu_lpc18_43_nxp -2 -pLPC4337 -wire=winusb
+    (gdb) load
+    (gdb) r
+    (gdb) c
+
+  NOTE 2:  Don't forget to enable CONFIG_DEBUG_SYMBOLS=y in your NuttX
+  configuration file when you build NuttX.  That option is necessary to build
+  in debugging symbols.
+
+  NOTE 3:  There are few things that NuttX has to do differently if you
+  are using a debugger.  Make sure that you also set CONFIG_DEBUG=y.  Nothing
+  also is needed and no debug output will be generated; but NuttX will
+  use CONFIG_DEBUG=y to mean that a debugger is attached and will deal
+  with certain resets and debug controls appropriately.
+
+  So you should have:
+
+    CONFIG_DEBUG=y
+    CONFIG_DEBUG_SYMBOLS=y
+
+  NOTE 4: Every time that you control-C out of the command line GDB, you
+  leave a copy of the Code Red debugger (crt_emu_lpc18_43_nxp) running.  I
+  have found that if you have these old copies of the debugger running,
+  hen strange things can happen when start yet another copy of the
+  debugger (I suspect that GDB may be talking with the wrong debugger).
+
+  If you exit GDB with quit (not control-C), it seems to clean-up okay.
+  But I have taken to keeping a Process Explorer window open all of the
+  time to keep track of how many of these bad processes have been created.
+
+  NOTE 5: There is also a certain function that is causing some problems.
+  The very first thing that the start-up logic does is call a function
+  called lpc43_softreset() which resets most of the peripherals.  But it
+  also causes some crashes... I think because the resets are causing some
+  interrupts.
+
+  I put a big delay in the soft reset logic between resetting and clearing
+  pending interrupts  and that seems to help some but I am not confident
+  that that is a fix.  I think that the real fix might be to just eliminated
+  this lpc43_softreset() function if we determine that it is not needed.
+
+  If you step over lpc43_softreset() after loading the coding (using the 'n'
+  command), then everything seems work okay.
+
+  Troubleshooting
+  ---------------
+
+  This page provides some troubleshooting information that you can use to
+  verify that the LPCLink is working correctly:
+
+    http://support.code-red-tech.com/CodeRedWiki/LPCLinkDiagnostics
+
+  Command Line Flash Programming
+  ------------------------------
+
+  The LPC18xx/LPC43xx debug driver can also be used to program the LPC43xx
+  flash directly from the command line.  The script flash.sh that may be
+  found in the configs/LPC4337-ws/scripts directory can do that with
+  a single command line command.
+
+  Executing from SPIFI
+  --------------------
+
+  By default, the configurations here assume that you are executing directly
+  from SRAM.
+
+    CONFIG_LPC43_BOOT_SRAM=y           : Executing in SRAM
+    CONFIG_ARMV7M_TOOLCHAIN_CODEREDW=y : Code Red under Windows
+
+  To execute from SPIFI, you would need to set:
+
+    CONFIG_LPC43_BOOT_SPIFI=y          : Executing from SPIFI
+    CONFIG_RAM_SIZE=(128*1024)         : SRAM Bank0 size
+    CONFIG_RAM_START=0x10000000        : SRAM Bank0 base address
+    CONFIG_SPIFI_OFFSET=(512*1024)     : SPIFI file system offset
+
+  To boot the LPC4337-ws from SPIFI the DIP switches should be 1-OFF,
+  2-ON, 3-ON, 4-ON (LOW LOW LOW HIGH in Table 19, MSB to LSB).
+
+  If the code in flash hard faults after reset and crt_emu_lpc18_43_nxp
+  can't reset the MCU, an alternative is to temporarily change switch 1
+  to  ON and press the reset button so it enters UART boot mode. Then
+  change it back to OFF and reset to boot again from flash.

+
+NuttX EABI "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
+  Bitbucket download site (https://bitbucket.org/nuttx/buildroot/downloads/).
+  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 LPC4337-ws/<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-eabi-defconfig-4.6.3 .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
+  details PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE:  Unfortunately, the 4.6.3 EABI toolchain is not compatible with the
+  the NXFLAT tools.  See the top-level TODO file (under "Binary loaders") for
+  more information about this problem. If you plan to use NXFLAT, please do not
+  use the GCC 4.6.3 EABI toochain; instead use the GCC 4.3.3 OABI toolchain.
+  See instructions below.
+
+NuttX OABI "buildroot" Toolchain
+================================
+
+  The older, OABI buildroot toolchain is also available.  To use the OABI
+  toolchain:
+
+  1. When building the buildroot toolchain, either (1) modify the cortexm3-eabi-defconfig-4.6.3
+     configuration to use EABI (using 'make menuconfig'), or (2) use an exising OABI
+     configuration such as cortexm3-defconfig-4.3.3
+
+  2. Modify the Make.defs file to use the OABI conventions:
+
+    +CROSSDEV = arm-nuttx-elf-
+    +ARCHCPUFLAGS = -mtune=cortex-m3 -march=armv7-m -mfloat-abi=soft
+    +NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections
+    -CROSSDEV = arm-nuttx-eabi-
+    -ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
+    -NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
+
+NXFLAT Toolchain
+================
+
+  If you are *not* using the NuttX buildroot toolchain and you want to use
+  the NXFLAT tools, then you will still have to build a portion of the buildroot
+  tools -- just the NXFLAT tools.  The buildroot with the NXFLAT tools can
+  be downloaded from the NuttX Bitbucket download site
+  (https://bitbucket.org/patacongo/nuttx/downloads/).
+
+  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 lpcxpresso-lpc1768/<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-nxflat .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly builtNXFLAT binaries.
+
+LED and Pushbuttons
+===================
+
+  LED
+  ---
+  The LPC4337-ws has one user-controllable LED labelled D6 controlled
+  by the signal LED_3V3:
+
+    LED SIGNAL  MCU
+    D6 LED_3V3 PE_& GPIO7[7]
+
+  A low output illuminates the LED.
+
+  If CONFIG_ARCH_LEDS is defined, the LED will be controlled as follows
+  for NuttX debug functionality (where NC means "No Change").
+
+    -------------------------- ---------
+                               LED
+    -------------------------- ---------
+    LED_STARTED                OFF
+    LED_HEAPALLOCATE           OFF
+    LED_IRQSENABLED            OFF
+    LED_STACKCREATED           ON
+    LED_INIRQ                  NC
+    LED_SIGNAL                 NC
+    LED_ASSERTION              NC
+    LED_PANIC                  Flashing
+    -------------------------- ---------
+
+  If CONFIG_ARCH_LEDS is not defined, then the LEDs are completely under
+  control of the application.  The following interfaces are then available
+  for application control of the LEDs:
+
+    void board_userled_initialize(void);
+    void board_userled(int led, bool ledon);
+    void board_userled_all(uint8_t ledset);
+
+  Pushbuttons
+  -----------
+  To be provided
+
+Serial Console
+==============
+
+The LPC4337-ws does not have RS-232 drivers or serial connectors on board.
+USART, USART2 and USART3 are available on J12 as follows:
+
+  ------ ------ -----------------------
+  SIGNAL J12 PIN  LPC4337FET256 PIN
+                  (TFBGA256 package)

+
+  GND  is available on J12 pins 29 and 30
+  5V   is available on J12 pin 2
+  3.3v id available on J12 pin 1
+
+FPU
+===
+
+FPU Configuration Options
+-------------------------
+
+There are two version of the FPU support built into the most NuttX Cortex-M4
+ports.  The current LPC43xx port support only one of these options, the "Non-
+Lazy Floating Point Register Save".  As a consequence, CONFIG_ARMV7M_CMNVECTOR
+must be defined in *all* LPC43xx configuration files.
+
+1. Lazy Floating Point Register Save.
+
+   This is an untested implementation that saves and restores FPU registers
+   only on context switches.  This means: (1) floating point registers are
+   not stored on each context switch and, hence, possibly better interrupt
+   performance.  But, (2) since floating point registers are not saved,
+   you cannot use floating point operations within interrupt handlers.
+
+   This logic can be enabled by simply adding the following to your .config
+   file:
+
+   CONFIG_ARCH_FPU=y
+
+2. Non-Lazy Floating Point Register Save
+
+   Mike Smith has contributed an extensive re-write of the ARMv7-M exception
+   handling logic. This includes verified support for the FPU.  These changes
+   have not yet been incorporated into the mainline and are still considered
+   experimental.  These FPU logic can be enabled with:
+
+   CONFIG_ARCH_FPU=y
+   CONFIG_ARMV7M_CMNVECTOR=y
+
+   You will probably also changes to the ld.script in if this option is selected.
+   This should work:
+
+   -ENTRY(_stext)
+   +ENTRY(__start)         /* Treat __start as the anchor for dead code stripping */
+   +EXTERN(_vectors)       /* Force the vectors to be included in the output */
+
+CFLAGS
+------
+
+Only the recent toolchains have built-in support for the Cortex-M4 FPU.  You will see
+the following lines in each Make.defs file:
+
+  ifeq ($(CONFIG_ARCH_FPU),y)
+    ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
+  else
+    ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
+  endif
+
+Configuration Changes
+---------------------
+
+Below are all of the configuration changes that I had to make to configs/stm3240g-eval/nsh2
+in order to successfully build NuttX using the Atollic toolchain WITH FPU support:
+
+  -CONFIG_ARCH_FPU=n                       : Enable FPU support
+  +CONFIG_ARCH_FPU=y
+
+  -CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : Disable the CodeSourcery toolchain
+  +CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=n
+
+  -CONFIG_ARMV7M_TOOLCHAIN_ATOLLIC=n       : Enable the Atollic toolchains
+  +CONFIG_ARMV7M_TOOLCHAIN_ATOLLIC=y       :
+
+  -CONFIG_INTELHEX_BINARY=y                : Suppress generation FLASH download formats
+  +CONFIG_INTELHEX_BINARY=n                : (Only necessary with the "Lite" version)
+
+  -CONFIG_HAVE_CXX=y                       : Suppress generation of C++ code
+  +CONFIG_HAVE_CXX=n                       : (Only necessary with the "Lite" version)
+
+See the section above on Toolchains, NOTE 2, for explanations for some of
+the configuration settings.  Some of the usual settings are just not supported
+by the "Lite" version of the Atollic toolchain.
+
+LPC4337-ws 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=lpc43xx
+

+
+       CONFIG_ARCH_CHIP_LPC4337=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.

+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_RAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_RAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_RAM_START - The start address of installed DRAM
+
+       CONFIG_RAM_START=0x10000000
+
+    CONFIG_ARCH_FPU - The LPC43xxx supports a floating point unit (FPU)
+
+       CONFIG_ARCH_FPU=y
+
+    CONFIG_LPC43_BOOT_xxx - The startup code needs to know if the code is running
+       from internal FLASH, external FLASH, SPIFI, or SRAM in order to
+       initialize properly.  Note that a boot device is not specified for
+       cases where the code is copied into SRAM; those cases are all covered
+       by CONFIG_LPC43_BOOT_SRAM.
+
+       CONFIG_LPC43_BOOT_SRAM=y      : Running from SRAM             (0x1000:0000)
+       CONFIG_LPC43_BOOT_SPIFI=y     : Running from QuadFLASH        (0x1400:0000)

+       CONFIG_LPC43_BOOT_CS3FLASH=y  : Running in external FLASH CS3 (0x1f00:0000)
+
+    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.

+
+  LPC43xx specific CAN device driver settings.  These settings all

+    CONFIG_LPC43_USBDEV_FRAME_INTERRUPT
+      Handle USB Start-Of-Frame events.
+      Enable reading SOF from interrupt handler vs. simply reading on demand.

+
+Configurations
+==============
+
+Each LPC4337-ws configuration is maintained in a sub-directory and can be selected
+as follow:
+
+    cd tools
+    ./configure.sh LPC4337-ws/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+  ----
+    This configuration is the NuttShell (NSH) example at examples/nsh/.
+
+    NOTES:
+
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configurations using that tool, you should:
+
+       a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+          see additional README.txt files in the NuttX tools repository.
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. The project can exucute directly from SRAM with NuttX loaded by a debugger
+       by setting the following configuration options.
+
+         CONFIG_LPC43_BOOT_SRAM=y           : Executing in SRAM
+         CONFIG_ARMV7M_TOOLCHAIN_CODEREDW=y : Code Red under Windows
+
+    3. To execute from SPIFI, you would need to set:
+
+         CONFIG_LPC43_BOOT_SPIFI=y      : Executing from SPIFI
+         CONFIG_RAM_SIZE=(128*1024)     : SRAM Bank0 size
+         CONFIG_RAM_START=0x10000000    : SRAM Bank0 base address
+         CONFIG_SPIFI_OFFSET=(512*1024) : SPIFI file system offset
+
+       CONFIG_MM_REGIONS should also be increased if you want to other SRAM banks
+       to the memory pool.
+
+    4. This configuration an also be used create a block device on the SPIFI
+       FLASH.  CONFIG_LPC43_SPIFI=y must also be defined to enable SPIFI setup
+       support:
+
+       SPIFI device geometry:
+
+         CONFIG_SPIFI_OFFSET - Offset the beginning of the block driver this many
+           bytes into the device address space.  This offset must be an exact
+           multiple of the erase block size (CONFIG_SPIFI_BLKSIZE). Default 0.
+         CONFIG_SPIFI_BLKSIZE - The size of one device erase block.  If not defined
+           then the driver will try to determine the correct erase block size by
+           examining that data returned from spifi_initialize (which sometimes
+           seems bad).
+
+       Other SPIFI options
+
+         CONFIG_SPIFI_SECTOR512 - If defined, then the driver will report a more
+           FAT friendly 512 byte sector size and will manage the read-modify-write
+           operations on the larger erase block.
+         CONFIG_SPIFI_READONLY - Define to support only read-only operations.
+         CONFIG_SPIFI_LIBRARY - Don't use the LPC43xx ROM routines but, instead,
+           use an external library implementation of the SPIFI interface.
+         CONFIG_SPIFI_VERIFY - Verify all spifi_program() operations by reading
+           from the SPI address space after each write.
+         CONFIG_DEBUG_SPIFI_DUMP - Debug option to dump read/write buffers.  You
+           probably do not want to enable this unless you want to dig through a
+           *lot* of debug output!  Also required CONFIG_DEBUG, CONFIG_DEBUG_VERBOSE,
+           and CONFIG_DEBUG_FS,
+
+    5. In my experience, there were some missing function pointers in the LPC43xx
+       SPIFI ROM routines and the SPIFI configuration could only be built with
+       CONFIG_SPIFI_LIBRARY=y.  The SPIFI library is proprietary and cannot be
+       provided within NuttX open source repository; SPIFI library binaries can
+       be found on the lpcware.com website.  In this build sceneario, you must
+       also provide the patch to the external SPIFI library be defining the make
+       variable EXTRA_LIBS in the top-level Make.defs file.  Good luck!
+
+   6. By default the LPC4337-ws port is configured to run from the onboard flash
+      bank A at 0x1a000000. In order to achieve this, the resulting NuttX binary
+      will need to have a checksum computed over the vector table and then be
+      converted to a hex file which can then be flashed using a debugger such as
+      the Uws through Keil.
+
+      The checksum can be computed using the checksum binary provided with the
+      LPCXpresso IDE software suite as follows:
+
+      ./checksum nuttx.bin -p LPC4337 -v
+
+      This will modify the binary file, appending the checksum to the correct place
+      at the end of the vector table.
+
+      The binary must now be converted to a hex file, which can be achieved using
+      the srec_cat utility, which is part of the SRecord package (srecord.sourceforge.net)
+      as follows:
+
+      srec_cat nuttx.bin -binary -offset 0x1a000000 -o nuttx.hex -intel --line-length=44
+
+      Now the hex file can be loaded using a debugger, and the code will execute from
+      flash.

+ * Power-Up Reset Overview
+ * -----------------------
+ *
+ * The ARM core starts executing code on reset with the program counter set
+ * to 0x0000 0000.  The LPC43xx contains a shadow pointer register that
+ * allows areas of memory to be mapped to address 0x0000 0000. The default,
+ * reset value of the shadow pointer is 0x1040 0000 so that on reset code in
+ * the boot ROM is always executed first.
+ *
+ * The boot starts after reset is released.  The IRC is selected as CPU clock
+ * and the Cortex-M4 starts the boot loader. By default the JTAG access to the
+ * chip is disabled at reset.  The boot ROM determines the boot mode based on
+ * the OTP BOOT_SRC value or reset state pins.  For flash-based parts, the part
+ * boots from internal flash by default.  Otherwse, the boot ROM copies the
+ * image to internal SRAM at location 0x1000 0000, sets the ARM's shadow
+ * pointer to 0x1000 0000, and jumps to that location.
+ *
+ * However, using JTAG the executable image can be also loaded directly into
+ * and executed from SRAM.
+ */

-MEMX
-^^^^
-
-  If you use the GCC AVR toolchain from the Atmel Studio, then you can
-  enable suppport for the MEMX storage:
-
-    CONFIG_AVR_HAS_MEMX_PTR=y
-
-  If this support is enabled, then all strings will be saved in FLASH and
-  standard string-oriented interfaces such printf() will change so that
-  they accept memx pointers.
-
-  This means that (1) ALL strings must lie in FLASH, and (2) since the
-  strings are moved from SRAM to FLASH, you will save a LOT of SRAM usage
-  in some configurations that use a lot of string memory (such as the
-  ostest and nsh configurations).
-
-  UPDATE 2016-01-07:  Unfortunately, there is an issue.  When I enable
-  CONFIG_AVR_HAS_MEMX_PTR=y in the nsh/ configuration, I get a number
-  of link time errors of this form:
-
-    FILENAME.c:(.text+0xOFFSET): warning: internal error: out of range error
-
-  This same build configuration works for the arduino-mega2560 so I am
-  suspecting some issue with the toolchain support for the AT90USB (avr:5)
-  vs the Atmega2560 (avr:6).
