+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 can be configured to support the various different
+ toolchain options. All testing has been conducted using the NuttX buildroot
+ toolchain. To use alternative toolchain, you simply need to add change of
+ the following configuration options to your .config (or defconfig) file:
+
+ CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
+ CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux
+ CONFIG_ARMV7M_TOOLCHAIN_ATOLLIC=y : Atollic toolchain for Windos
+ CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=y : devkitARM under Windows
+ CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
+ CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIL=y : Generic GCC ARM EABI toolchain for Linux
+ CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : Generic GCC ARM EABI toolchain for Windows
+
+ You may also have to modify the PATH in the setenv.h file if your
+ make cannot find the tools.
+
+ NOTE about Windows native toolchains
+ ------------------------------------
+
+ There are basically three kinds of GCC toolchains that can be used:
+
+ 1. A Linux native toolchain in a Linux environment,
+ 2. The buildroot Cygwin tool chain built in the Cygwin environment,
+ 3. A Windows native toolchain.
+
+ There are several limitations to using a Windows based toolchain (#3) 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 paths which do
+ not work with the Cygwin make.
+
+ MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+
+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/sam34,
+ 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/sam34/sam_vectors.S. You may need to build NuttX
+ one time from the Cygwin command line in order to obtain the pre-built
+ startup object needed by RIDE.
+
+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
+ 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 sam4e-ek/<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 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 sam4e-ek/<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.

+ You can use AtmelStudio6.1 to load and debug code.
+
+ - To load code:
+
+ Tools -> Device Programming
+
+ Configure the debugger and chip and you are in business.
+
+ - To Debug Code:
+
+ File -> Open -> Open Object File for Debugging
+
+ Select the project name, the full path to the NuttX object (called
+ just nuttx with no extension), and chip. Take the time to resolve
+ all of the source file linkages or else you will not have source
+ level debug!
+
+LEDs
+^^^^
+
+ The SAM4E-EK board has three, user-controllable LEDs labelled D2 (blue),
+ D3 (amber), and D4 (green) on the board. Usage of these LEDs is defined
+ in include/board.h and src/up_leds.c. They are encoded as follows:
+
+ SYMBOL Meaning D3* D2 D4
+ ------------------- ----------------------- ------- ------- -------
+ LED_STARTED NuttX has been started OFF OFF OFF
+ LED_HEAPALLOCATE Heap has been allocated OFF OFF ON
+ LED_IRQSENABLED Interrupts enabled OFF ON OFF
+ LED_STACKCREATED Idle stack created OFF ON ON
+ LED_INIRQ In an interrupt** N/C FLASH N/C
+ LED_SIGNAL In a signal handler*** N/C N/C FLASH
+ LED_ASSERTION An assertion failed FLASH N/C N/C
+ LED_PANIC The system has crashed FLASH N/C N/C
+
+ * If D2 and D4 are statically on, then NuttX probably failed to boot
+ and these LEDs will give you some indication of where the failure was
+ ** The normal state is D3=OFF, D4=ON and D2 faintly glowing. This faint
+ glow is because of timer interrupts that result in the LED being
+ illuminated on a small proportion of the time.
+*** D4 may also flicker normally if signals are processed.
+
+Serial Console
+^^^^^^^^^^^^^^
+
+ By default, all of these configurations use UART0 for the NuttX serial
+ console. UART0 corresponds to the DB-9 connector labelled "UART". This
+ is a male connector and will require a female-to-female, NUL modem cable
+ to connect to a PC.
+
+ An alternate is USART1 which connects to the other DB-9 connector labeled
+ "USART". USART1 is not enabled by default unless specifically noted
+ otherwise in the configuration description. A NUL modem cable must be
+ used with the port as well.
+
+ NOTE: One of the USART1 pins is shared with the audio CODEC. The audio
+ CODEC cannot be used of USART1 is enabled.
+
+ By default serial console is configured for 115000, 8-bit, 1 stop bit, and
+ no parity.
+
+SAM4E-EK-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_CORTEXM3=y
+
+ CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory

+ chip:
+
+ CONFIG_ARCH_CHIP_SAM34
+ CONFIG_ARCH_CHIP_SAM3U
+ CONFIG_ARCH_CHIP_ATSAM3U4
+
+ CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+ hence, the board that supports the particular chip or SoC.
+
+ CONFIG_ARCH_BOARD=sam4e-ek (for the SAM4E-EK development board)
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_SAM4EEK=y

+
+ CONFIG_RAM_SIZE=0x00020000 (128Kb)
+
+ CONFIG_RAM_START - The start address of installed DRAM
+
+ CONFIG_RAM_START=0x20000000
+
+ CONFIG_ARCH_IRQPRIO - The SAM3U supports interrupt prioritization
+
+ CONFIG_ARCH_IRQPRIO=n
+
+ CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that

+
+Configurations
+^^^^^^^^^^^^^^
+
+ Information Common to All Configurations
+ ----------------------------------------
+ Each SAM4E-EK configuration is maintained in a sub-directory and
+ can be selected as follow:
+
+ cd tools
+ ./configure.sh sam4e-ek/<subdir>
+ cd -
+ . ./setenv.sh
+
+ Before sourcing the setenv.sh file above, you should examine it and perform
+ edits as necessary so that BUILDROOT_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 UART0 (J3).
+
+ 3. Unless otherwise stated, the configurations are setup for
+ Linux (or any other POSIX environment like Cygwin under Windows):
+
+ Build Setup:
+ CONFIG_HOST_LINUX=y : Linux or other POSIX environment
+
+ 4. All of these configurations use the older, OABI, buildroot 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_LINUX=y : Linux or other pure POSIX invironment
+ : (including Cygwin)
+ System Type -> Toolchain:
+ CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot toolchain
+ CONFIG_ARMV7M_OABI_TOOLCHAIN=y : Older, OABI toolchain
+
+ If you want to use the Atmel GCC toolchain, for example, here are the
+ steps to do so:
+
+ Build Setup:
+ CONFIG_HOST_WINDOWS=y : Windows
+ CONFIG_HOST_CYGWIN=y : Using Cygwin or other POSIX environment
+
+ System Type -> Toolchain:
+ CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : General GCC EABI toolchain under windows
+
+ Library Routines ->
+ CONFIG_CXX_NEWLONG=n : size_t is an unsigned int, not long
+
+ This re-configuration should be done before making NuttX or else the
+ subsequent 'make' will fail. If you have already attempted building
+ NuttX then you will have to 1) 'make distclean' to remove the old
+ configuration, 2) 'cd tools; ./configure.sh sam4e-ek/ksnh' to start
+ with a fresh configuration, and 3) perform the configuration changes
+ above.
+
+ Also, make sure that your PATH variable has the new path to your
+ Atmel tools. Try 'which arm-none-eabi-gcc' to make sure that you
+ are selecting the right tool. setenv.sh is available for you to
+ use to set or PATH variable. The path in the that file may not,
+ however, be correct for your installation.
+
+ See also the "NOTE about Windows native toolchains" in the section call
+ "GNU Toolchain Options" above.
+
+ Configuration sub-directories
+ -----------------------------
+
+ nsh:
+ Configures the NuttShell (nsh) located at examples/nsh. The
+ Configuration enables both the serial and telnetd NSH interfaces.
+
+ NOTES:
+
+ 1. NSH built-in applications are supported. However, there are
+ no built-in applications built with the default configuration.
+
+ Binary Formats:
+ CONFIG_BUILTIN=y : Enable support for built-in programs
+
+ Applicaton Configuration:
+ CONFIG_NSH_BUILTIN_APPS=y : Enable starting apps from NSH command line
+
+ 2. This configuration has been used for verifying the touchscreen on
+ on the SAM4E-EK LCD. With these modifications, you can include the
+ touchscreen test program at apps/examples/touchscreen as an NSH built-in
+ application. You can enable the touchscreen and test by modifying the
+ default configuration in the following ways:
+
+ Device Drivers
+ CONFIG_SPI=y : Enable SPI support
+ CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
+ CONFIG_SPI_OWNBUS=y : Smaller code if this is the only SPI device
+
+ CONFIG_INPUT=y : Enable support for input devices
+ CONFIG_INPUT_ADS7843E=y : Enable support for the XPT2046
+ CONFIG_ADS7843E_SPIDEV=2 : Use SPI CS 2 for communication
+ CONFIG_ADS7843E_SPIMODE=0 : Use SPI mode 0
+ CONFIG_ADS7843E_FREQUENCY=1000000 : SPI BAUD 1MHz
+ CONFIG_ADS7843E_SWAPXY=y : If landscpe orientation
+ CONFIG_ADS7843E_THRESHX=51 : These will probably need to be tuned
+ CONFIG_ADS7843E_THRESHY=39
+
+ System Type -> Peripherals:
+ CONFIG_SAM34_SPI0=y : Enable support for SPI
+
+ System Type:
+ CONFIG_GPIO_IRQ=y : GPIO interrupt support
+ CONFIG_GPIOA_IRQ=y : Enable GPIO interrupts from port A
+
+ RTOS Features:
+ CONFIG_DISABLE_SIGNALS=n : Signals are required
+
+ Library Support:
+ CONFIG_SCHED_WORKQUEUE=y : Work queue support required
+
+ Applicaton Configuration:
+ CONFIG_EXAMPLES_TOUCHSCREEN=y : Enable the touchscreen built-int test
+
+ Defaults should be okay for related touchscreen settings. Touchscreen
+ debug output on UART0 can be enabled with:
+
+ Build Setup:
+ CONFIG_DEBUG=y : Enable debug features
+ CONFIG_DEBUG_VERBOSE=y : Enable verbose debug output
+ CONFIG_DEBUG_INPUT=y : Enable debug output from input devices
+
+ 3. Enabling HSMCI support. The SAM3U-KE provides a an SD memory card
+ slot. Support for the SD slot can be enabled with the following
+ settings:
+
+ System Type->ATSAM3/4 Peripheral Support
+ CONFIG_SAM34_HSMCI=y : Enable HSMCI support
+ CONFIG_SAM34_DMAC=y : DMAC support is needed by HSMCI
+
+ System Type
+ CONFIG_SAM34_GPIO_IRQ=y : PIO interrupts needed
+ CONFIG_SAM34_GPIOA_IRQ=y : Card detect pin is on PIOA
+
+ Device Drivers -> MMC/SD Driver Support
+ CONFIG_MMCSD=y : Enable MMC/SD support
+ CONFIG_MMSCD_NSLOTS=1 : One slot per driver instance
+ CONFIG_MMCSD_HAVECARDDETECT=y : Supports card-detect PIOs
+ CONFIG_MMCSD_SDIO=y : SDIO-based MMC/SD support
+ CONFIG_SDIO_DMA=y : Use SDIO DMA
+ CONFIG_SDIO_BLOCKSETUP=y : Needs to know block sizes
+
+ Library Routines
+ CONFIG_SCHED_WORKQUEUE=y : Driver needs work queue support
+
+ Application Configuration -> NSH Library
+ CONFIG_NSH_ARCHINIT=y : NSH board-initialization
+
+ STATUS:
+ 2013-6-28: The touchscreen is functional.
+ 2013-6-29: Hmmm... but there appear to be conditions when the
+ touchscreen driver locks up. Looks like some issue with
+ managing the interrupts.
+ 2013-6-30: Those lock-ups appear to be due to poorly placed
+ debug output statements. If you do not enable debug output,
+ the touchscreen is rock-solid.
+ 2013-8-10: Added the comments above above enabling HSMCI memory
+ card support and verified that the configuration builds without
+ error. However, that configuration has not yet been tested (and
+ is may even be incomplete).

+ * The LCD module gets its reset from NRST. As explained previously, this NRST is
+ * shared with the JTAG port and the push button BP1. The LCD chip select signal is
+ * connected to NCS2 (a dedicated jumper can disable it, making NCS2 available for
+ * other custom usage).
+ *
+ * The SAM3U4E communicates with the LCD through PIOB where a 16-bit parallel
+ * 8080-like protocol data bus has to be implemented by software.
+ *
+ * LCD backlight is made of 4 white chip LEDs in parallel, driven by an AAT3194
+ * charge pump, MN4. The AAT3194 is controlled by the SAM3U4E through a single line
+ * Simple Serial Control (S2Cwire) interface, which permits to enable, disable, and
+ * set the LED drive current (LED brightness control) from a 32-level logarithmic
+ * scale. Four resistors R93/R94/R95/R96 are implemented for optional current
+ * limitation.
+ *
+ * The LCD module integrates a 4-wire touch screen panel controlled by
+ * MN5, ADS7843, which is a slave device on the SAM3U4E SPI bus. The ADS7843 touch
+ * ADC auxiliary inputs IN3/IN4 are connected to test points for optional function
+ * extension.
