+
+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 devkitARM GNU toolchain,
+ 4. The NuttX buildroot Toolchain (see below).
+
+ All testing has been conducted using the Code Red toolchain and the
+ make system is setup to default to use the Code Red Linux toolchain. To use
+ the other 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)
+ CONFIG_LPC17_CODEREDW=n : Code Red toolchain under Windows
+ CONFIG_LPC17_CODEREDL=y : Code Red toolchain under Linux
+
+ 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), devkitARM, and Code Red (for Windoes)
+ are Windows native toolchains. The CodeSourcey (for Linux), Code Red (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.
+
+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/).
+ 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 zkit-arm-1769/<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: The cortexm3-defconfig-4.3.3 produces an older-style is OABI toolchain.
+ There is another configuration, cortexm3-eabi-defconfig-4.6.3, that will
+ build a newer, EABI, toolchain. Unfortunately, the 4.6.3 EABI toolchain is
+ not compatible with 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.
+
+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 SourceForge download site
+ (https://sourceforge.net/projects/nuttx/files/).
+
+ 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 zkit-arm-1769/<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.
+
+LEDs
+^^^^
+
+ If CONFIG_ARCH_LEDS is defined, then support for the ZKit-ARM LEDs will be
+ included in the build. See:
+
+ - configs/zkit-arm-1769/include/board.h - Defines LED constants, types and
+ prototypes the LED interface functions.
+
+ - configs/zkit-arm-1769/src/zkitarm_internal.h - GPIO settings for the LEDs.
+
+ - configs/zkit-arm-1769/src/up_leds.c - LED control logic.
+
+ The ZKit-ARM LPC1768 has a single LEDs (there are more on the Embedded Artists
+ base board, but those are not controlled by NuttX). Usage this single LED by NuttX
+ is as follows:
+
+ - The LED is not illuminated until the ZKit-ARM completes initialization.
+
+ If the LED is stuck in the OFF state, this means that the ZKit-ARM did not
+ complete intialization.
+
+ - Each time the OS enters an interrupt (or a signal) it will turn the LED OFF and
+ restores its previous stated upon return from the interrupt (or signal).
+
+ The normal state, after initialization will be a dull glow. The brightness of
+ the glow will be inversely related to the proportion of time spent within interrupt
+ handling logic. The glow may decrease in brightness when the system is very
+ busy handling device interrupts and increase in brightness as the system becomes
+ idle.
+
+ Stuck in the OFF state suggests that that the system never completed
+ initialization; Stuck in the ON state would indicated that the system
+ intialialized, but is not takint interrupts.
+
+ - If a fatal assertion or a fatal unhandled exception occurs, the LED will flash
+ strongly as a slow, 2Hz rate.
+
+ZKit-ARM Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ General Architecture Settings:
+
+ 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=zkit-arm-1769
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_ZKITARM=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_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
+ 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.

+ cd tools
+ ./configure.sh zkit-arm-1769/<subdir>
+ cd -
+ . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+ hello:
+ This builds an example application using apps/examples/hello. See
+ apps/examples/README.txt for information about the examples.
+
+ thttpd:
+ This builds the THTTPD web server example using the THTTPD and

+ * 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
