+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.
+
+Code Red IDE
+^^^^^^^^^^^^
+
+ 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 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-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.
+
+LEDs
+^^^^
+
+ If CONFIG_ARCH_LEDS is defined, then support for the LPCXpresso LEDs will be
+ included in the build. See:
+
+ - configs/lpcxpresso-lpc1768/include/board.h - Defines LED constants, types and
+ prototypes the LED interface functions.
+
+ - configs/lpcxpresso-lpc1768/src/lpcxpresso_internal.h - GPIO settings for the LEDs.
+
+ - configs/lpcxpresso-lpc1768/src/up_leds.c - LED control logic.
+
+ The LPCXpresso has 3 LEDs... two on the Babel CAN board and a "heartbeat" LED."
+ The LEDs on the Babel CAN board are capabl of OFF/GREEN/RED/AMBER status.
+ In normal usage, the two LEDs on the Babel CAN board would show CAN status, but if
+ CONFIG_ARCH_LEDS is defined, these LEDs will be controlled as follows for NuttX
+ debug functionality (where NC means "No Change").
+
+ During the boot phases. LED1 and LED2 will show boot status.
+
+ /* LED1 LED2 HEARTBEAT */
+ #define LED_STARTED 0 /* OFF OFF OFF */
+ #define LED_HEAPALLOCATE 1 /* GREEN OFF OFF */
+ #define LED_IRQSENABLED 2 /* OFF GREEN OFF */
+ #define LED_STACKCREATED 3 /* OFF OFF OFF */
+
+ #define LED_INIRQ 4 /* NC NC ON (momentary) */
+ #define LED_SIGNAL 5 /* NC NC ON (momentary) */
+ #define LED_ASSERTION 6 /* NC NC ON (momentary) */
+ #define LED_PANIC 7 /* NC NC ON (0.5Hz flashing) */
+ #undef LED_IDLE /* Sleep mode indication not supported */
+
+ After the system is booted, this logic will no longer use LEDs 1 and 2. They
+ are then available for use the application software using lpc17_led1() and
+ lpc17_led2():
+
+ enum lpc17_ledstate_e
+ {
+ LPC17_LEDSTATE_OFF = 0,
+ LPC17_LEDSTATE_GREEN = 1,
+ LPC17_LEDSTATE_RED = 2,
+ LPC17_LEDSTATE_AMBER = (LPC17_LEDSTATE_GREEN|LPC17_LEDSTATE_RED),
+ };
+
+ EXTERN void lpc17_led1(enum lpc17_ledstate_e state);
+ EXTERN void lpc17_led2(enum lpc17_ledstate_e state);
+
+ The heartbeat LED is illuminated during all interrupt and signal procressing.
+ Normally, it will glow dimly to inicate that the LPC17xx is taking interrupts.
+ On an assertion PANIC, it will flash at 1Hz.
+
+LPCXpresso 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=lpcxpresso-lpc1768
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_LPCEXPRESSO=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
+ stack. If defined, this symbol is the size of the interrupt

+ 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.

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