+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.
+
+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. Raisonance GNU toolchain,
+  4. The NuttX buildroot Toolchain (see below), or
+  5. Any generic arm-none-eabi GNU toolchain.
+
+  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, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_ARM_TOOLCHAIN_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_ARM_TOOLCHAIN_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_ARM_TOOLCHAIN_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_ARM_TOOLCHAIN_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+    CONFIG_ARM_TOOLCHAIN_GNU_EABIL        : Generic arm-none-eabi toolchain for Linux
+    CONFIG_ARM_TOOLCHAIN_GNU_EABIW        : Generic arm-none-eabi toolchain for Windows
+
+  If you are not using CONFIG_ARM_TOOLCHAIN_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  The toolchain may also be set using the kconfig-mconf utility (make menuconfig) or by
+  passing CONFIG_ARM_TOOLCHAIN=<toolchain> to make, where <toolchain> is one
+  of CODESOURCERYW, CODESOURCERYL, DEVKITARM, BUILDROOT or GNU_EABI as described
+  above.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains 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.
+
+       MKDEP                = $(TOPDIR)/tools/mknulldeps.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.
+
+  Generic arm-none-eabi GNU Toolchain
+  -----------------------------------
+  There are a number of toolchain projects providing support for ARMv4/v5
+  class processors, including:
+
+    GCC ARM Embedded
+      https://launchpad.net/gcc-arm-embedded
+
+    Summon ARM Toolchain
+      https://github.com/esden/summon-arm-toolchain
+
+    Yagarto
+      http://www.yagarto.de
+
+  Others exist for various Linux distributions, MacPorts, etc.  Any version
+  based on GCC 4.6.3 or later should work.
+
+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 (There is a simple RIDE project
+  in the RIDE subdirectory).
+
+  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/lpc31xx,
+     arch/arm/src/common, arch/arm/src/arm, 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/lpc31xx/lpc31_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+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/projects/nuttx/files/buildroot/).
+  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 olimex-lpc-h3131/<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/arm926t-defconfig-4.2.4 .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.
+
+Boot Sequence
+=============
+
+  LPC313x has on chip bootrom which loads properly formatted images from multiple
+  sources into SRAM.  These sources include including SPI Flash, NOR Flash, UART,
+  USB, SD Card, and NAND Flash.
+
+  In all configurations, NuttX is loaded directly into ISRAM.  NuttX is linked
+  to execute from ISRAM, regardless of the boot source.
+
+Buttons and LEDs
+================
+
+  Buttons
+  -------
+
+  There are not user buttons on the H3131
+
+  LEDs
+  ----
+
+  There are two LEDs on the LPC-H3131 that can be controlled by software:
+
+      LED              GPIO
+      ---------------- -----
+      LED1 Yellow      GPIO17 High output illuminates
+      LED2 Green       GPIO18 High output illuminates
+
+  Both can be illuminated by driving the GPIO output to high.
+
+  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/lpc31_leds.c. The LEDs are used to encode
+  OS-related events as follows:
+
+    SYMBOL                Meaning                     LED state
+                                                    LED2     LED1
+    -------------------  -----------------------  -------- --------
+    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            N/C      N/C
+    LED_SIGNAL           In a signal handler        N/C      N/C
+    LED_ASSERTION        An assertion failed        N/C      N/C
+    LED_PANIC            The system has crashed     N/C      Blinking
+    LED_IDLE             MCU is is sleep mode         Not used
+
+  Thus if LED2 is statically on, NuttX has successfully booted and is,
+  apparently, running normmally.  If LED1 is flashing at approximately
+  2Hz, then a fatal error has been detected and the system has halted.
+
+  NOTE: That LED2 is not used after completion of booting and may
+  be used by other board-specific logic.
+
+Image Format
+============
+
+  In order to use the bootrom bootloader, a special header must be added to the
+  beginning of the binary image that includes information about the binary (things
+  like the entry point, the size, and CRC's to verify the image.
+
+  NXP provides a Windows program to append such a header to the binary image.
+  However, (1) that program won't run under Linux, and (2) when I try it under
+  WinXP, Symantec immediately claims that the program is misbehaving and deletes
+  it!
+
+  To work around both of these issues, I have created a small program under
+  configs/olimex-lpc-h3131/tools to add the header.  This program can be built under
+  either Linux or Cygwin (and probably other tool environments as well).  That
+  tool can be built as follows:
+
+  - cd configs/olimex-lpc-h3131/tools
+  - make
+
+  Then, to build the NuttX binary ready to load with the bootloader, just
+  following these steps:
+
+  - cd tools/                     # Configure Nuttx
+  - ./configure.sh olimex-lpc-h3131/ostest  # (using the ostest configuration for this example)
+  - cd ..                         # Set up environment
+  - . ./setenv.sh                 # (see notes below)
+  - make                          # Make NuttX.  This will produce nuttx.bin
+  - mklpc.sh                      # Make the bootloader binary (nuttx.lpc)
+
+  NOTES:
+  
+    1. setenv.sh just sets up pathes to the toolchain and also to
+       configs/olimex-lpc-h3131/tools where mklpc.sh resides. Use of setenv.sh is optional.
+       If you don't use setenv.sh, then just set your PATH variable appropriately or
+       use the full path to mklpc.sh in the final step.
+    2. You can instruct Symantec to ignore the errors and it will stop quarantining
+       the NXP program.
+    3. The CRC32 logic in configs/olimex-lpc-h3131/tools doesn't seem to work.  As a result,
+       the CRC is currently disabled in the header:
+
+       RCS file: /cvsroot/nuttx/nuttx/configs/olimex-lpc-h3131/tools/lpchdr.c,v
+       retrieving revision 1.2
+       diff -r1.2 lpchdr.c
+       264c264
+       <   g_hdr.imageType       = 0x0000000b;
+       ---
+       >   g_hdr.imageType       = 0x0000000a;
+
+Image Download to ISRAM
+=======================
+
+Assuming that you already have the FTDI driver installed*, then here is the
+are the steps that I use for loading new code into the LPC-H3131:
+
+- Create the bootloader binary, nuttx.lpc, as described above.
+- Connected the LPC-H3131 using the FTDI USB port (not the lpc3131 USB port)
+  This will power up the LPC-H3131 and start the bootloader.
+- Start a terminal emulator (such as TeraTerm) at 115200 8NI.
+- Reset the LPC-H3131 and you should see:
+  LPC31xx READY FOR PLAIN IMAGE>
+- Send the nuttx.lpc file and you should see:
+  Download finished
+
+That will load the NuttX binary into ISRAM and attempt to execute it.
+
+*See the LPC313x documentation if you do not have the FTDI driver installed.
+
+Using OpenOCD and GDB
+=====================
+  [NOTE:  As of this writing, my OpenOCD script does NOT work.  It fails
+   because it is unable to halt the LPC3131.  So, unfortunately, OpenOCD
+   is not a option right now.]
+
+  I have been using the Olimex ARM-USB-OCD JTAG debugger with the LPC-H3131
+  (http://www.olimex.com).  The OpenOCD configuration file is here:
+  tools/armusbocb.cfg.  There is also a script on the tools directory that
+  I used to start the OpenOCD daemon on my system called oocd.sh.  That
+  script would probably require some modifications to work in another
+  environment:
+  
+    - possibly the value of OPENOCD_PATH
+    - If you are working under Linux you will need to change any
+      occurances of `cygpath -w blablabla` to just blablabla
+
+  Then you should be able to start the OpenOCD daemon like:
+
+    configs/olimex-lpc-h3131/tools/oocd.sh $PWD
+
+  Where it is assumed that you are executing oocd.sh from the top level
+  directory where NuttX is installed.
+
+  Once the OpenOCD daemon has been started, you can connect to it via
+  GDB using the following GDB command:
+
+   arm-nuttx-elf-gdb
+   (gdb) target remote localhost:3333
+
+  And you can load the NuttX ELF file:
+
+   (gdb) symbol-file nuttx
+   (gdb) load nuttx
+
+ARM/LPC-H3131-specific 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_ARM926EJS=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=lpc313x
+
+    CONFIG_ARCH_CHIP_name - For use in C code
+
+       CONFIG_ARCH_CHIP_LPC3131
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD="olimex-lpc-h3131"
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_OLIMEX_LPC_H3131
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_RAM_SIZE - For most ARM9 architectures, this describes the
+      size of installed DRAM.  For the LPC313X, it is used only to
+      deterimine how to map the executable regions.  It is SDRAM size
+      only if you are executing out of the external SDRAM; or it could
+      be NOR FLASH size, external SRAM size, or internal SRAM size.
+
+    CONFIG_RAM_START - The start address of installed DRAM (physical)
+
+    CONFIG_RAM_VSTART - The startaddress of DRAM (virtual)
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_IRQPRIO - The LPC313x supports interrupt prioritization
+
+    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_BOOTLOADER - Set if you are using a bootloader.
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_BUTTONS -  Enable support for buttons. 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.
+    CONFIG_ARCH_DMA - Support DMA initialization
+    CONFIG_ARCH_LOWVECTORS - define if vectors reside at address 0x0000:00000
+      Undefine if vectors reside at address 0xffff:0000
+    CONFIG_ARCH_ROMPGTABLE - A pre-initialized, read-only page table is available.
+      If defined, then board-specific logic must also define PGTABLE_BASE_PADDR,
+      PGTABLE_BASE_VADDR, and all memory section mapping in a file named
+      board_memorymap.h.
+
+  Individual subsystems can be enabled:
+

+
+  External memory available on the board (see also CONFIG_MM_REGIONS)
+
+    CONFIG_LPC31_EXTSRAM0 - Select if external SRAM0 is present
+    CONFIG_LPC31_EXTSRAM0HEAP - Select if external SRAM0 should be
+      configured as part of the NuttX heap.

+
+  Information Common to All Configurations
+  ----------------------------------------
+  Each LPC-H3131 configuration is maintained in a sub-directory and can be
+  selected as follow:
+
+    cd tools
+    ./configure.sh olimex-lpc-h3131/<subdir>
+    cd -
+    . ./setenv.sh
+
+  Before sourcing the setenv.sh file above, you should examine it and perform
+  edits as necessary so that TOOLCHAIN_BIN is the correct path to the directory
+  than holds your toolchain binaries.
+
+  And then build NuttX by simply typing the following.  At the conclusion of
+  the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
+
+    make
+
+  The <subdir> that is provided above as an argument to the tools/configure.sh
+  must be is one of the following.
+
+  NOTES:
+
+  1. These configurations use the mconf-based configuration tool.  To
+    change any of these configurations using that tool, you should:
+
+    a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+       and misc/tools/
+
+    b. Execute 'make menuconfig' in nuttx/ in order to start the
+       reconfiguration process.
+
+  2. Unless stated otherwise, all configurations generate console
+     output on the UART0 associated with the FT232RL USB-to UART
+     converter.
+
+  3. Unless otherwise stated, the configurations are setup for
+     Windows undery Cygwin.  This can, however, be easilty reconfigured.
+
+  4. All of these configurations use the Code Sourcery for Windows toolchain
+     (unless stated otherwise in the description of the configuration).  That
+     toolchain selection can easily be reconfigured using 'make menuconfig'.
+     Here are the relevant current settings:
+
+     Build Setup:
+       CONFIG_HOST_WINDOS=y                : Microsoft Windows
+       CONFIG_WINDOWS_CYGWIN=y             : Using Cygwin or other POSIX environment
+
+     System Type -> Toolchain:
+       CONFIG_ARM_TOOLCHAIN_GNU_EABIW=y : GNU EABI toolchain for windows
+
+     The setenv.sh file is available for you to use to set the PATH
+     variable.  The path in the that file may not, however, be correct
+     for your installation.
+
+  Configuration sub-directories
+  -----------------------------
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables only the serial NSH interface.

+ *      board-specific logic.  These functions will perform chip selection and

+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the

+ * This file is a part of NuttX:
+ *
+ *   Copyright (C) 2013 Gregory Nutt. All rights reserved.
+ *
+ * The logic in this file was developed by Gary S. Brown:
+ *
+ *   COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or code or tables
+ *   extracted from it, as desired without restriction.
+ *
+ * First, the polynomial itself and its table of feedback terms.  The polynomial is:
+ *
+ *    X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ * Note that we take it "backwards" and put the highest-order term in the lowest-order bit.
+ * The X^32 term is "implied"; the LSB is the X^31 term, etc.  The X^0 term (usually shown
+ * as "+1") results in the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which is what we're using
+ * (we're merely optimizing it by doing eight-bit chunks at a time) shifts bits into the
+ * lowest-order term.  In our implementation, that means shifting towards the right.  Why
+ * do we do it this way?  Because the calculated CRC must be transmitted in order from
+ * highest-order term to lowest-order term.  UARTs transmit characters in order from LSB
+ * to MSB.  By storing the CRC this way we hand it to the UART in the order low-byte to
+ * high-byte; the UART sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit shuffling on our
+ * part.  Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ * - The table can be generated at runtime if desired; code to do so is shown later.  It
+ *   might not be obvious, but the feedback terms simply represent the results of eight
+ *   shift/xor operations for all combinations of data and CRC register values
+ *
+ * - The values must be right-shifted by eight bits by the updcrc logic; the shift must
+ *   be u_(bring in zeroes).  On some hardware you could probably optimize the shift in
+ *   assembler by using byte-swap instructions polynomial $edb88320

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).
