+^^^^^^^^^^^^^^^^^^^

+GPIO Usage -- To be provided
+
+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 toolchain, you simply need add one of the
+  following configuration options to your .config (or defconfig) file:
+
+    CONFIG_LPC17_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LPC17_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LPC17_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LPC17_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC17_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 (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/lpc17xx,
+     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/lpc17x/lpc17_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 detron/<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.

+
+Detron 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=lpc17xx
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_LPC1768=y
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=detron (for the Detron board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_DETRON=y
+
+	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 (CPU SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+	   There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x10000000
+
+	CONFIG_DRAM_END - Last address+1 of installed RAM
+
+	   CONFIG_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
+
+	CONFIG_ARCH_IRQPRIO - The LPC17xx 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

+
+USB Host Configuration
+^^^^^^^^^^^^^^^^^^^^^^
+
+The NuttShell (NSH) Detron configuration can be modified in order
+to support USB host operations.  To make these modifications, do the
+following:
+
+1. First configure to build the NSH configuration from the top-level
+   NuttX directory:
+
+   cd tools
+   ./configure detron/nsh
+   cd ..
+
+2. Then edit the top-level .config file to enable USB host.  Make the
+   following changes:
+
+   CONFIG_LPC17_USBHOST=n
+   CONFIG_USBHOST=n
+   CONFIG_SCHED_WORKQUEUE=y
+
+When this change is made, NSH should be extended to support USB flash
+devices.  When a FLASH device is inserted, you should see a device
+appear in the /dev (psuedo) directory.  The device name should be
+like /dev/sda, /dev/sdb, etc.  The USB mass storage device, is present
+it can be mounted from the NSH command line like:
+
+   ls /dev
+   mount -t vfat /dev/sda /mnt/flash
+
+Files on the connect USB flash device should then be accessible under
+the mountpoint /mnt/flash.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Detron configuration is maintained in a sudirectory and can be
+selected as follow:
+
+	cd tools
+	./configure.sh detron/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  hidkbd:
+    This configuration directory, performs a simple test of the USB host
+    HID keyboard class driver using the test logic in examples/hidkbd.
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables only the serial  NSH interfaces.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.
+
+  usbserial:
+    This configuration directory exercises the USB serial class
+    driver at examples/usbserial.  See examples/README.txt for
+    more information.
+
+  usbstorage:
+    This configuration directory exercises the USB mass storage
+    class driver at examples/usbstorage.  See examples/README.txt for
+    more information.

+ *   must be provided by board-specific logic.  They are implementations of the select
+ *   and status methods of the SPI interface defined by struct spi_ops_s (see
+ *   include/nuttx/spi.h). All other methods (including up_spiinitialize())
+ *   are provided by common LPC17xx logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in lpc17_boardinitialize() to configure SPI/SSP chip select
+ *      pins.
+ *   2. Provide lpc17_ssp0/ssp1select() and lpc17_ssp0/ssp1status() functions
+ *      in your board-specific logic.  These functions will perform chip selection
+ *      and status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. 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).
