+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.

+	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

+	    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.

+  LPC17xx specific device driver settings

+

+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the

+	   console and ttys0 (default is the UART0).

+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.

+	   This specific the size of the receive buffer

+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before

+	   being sent.  This specific the size of the transmit buffer

+	CONFIG_UARTn_2STOP - Two stop bits

+

+  LPC17xx specific PHY/Ethernet device driver settings.  These setting

+  also require CONFIG_NET and CONFIG_LPC17_ETHERNET.

+

+	CONFIG_PHY_KS8721 - Selects Micrel KS8721 PHY

+	CONFIG_PHY_AUTONEG - Enable auto-negotion

+	CONFIG_PHY_SPEED100 - Select 100Mbit vs. 10Mbit speed.

+	CONFIG_PHY_FDUPLEX - Select full (vs. half) duplex

+

+    CONFIG_NET_EMACRAM_SIZE - Size of EMAC RAM.  Default: 16Kb

+	CONFIG_NET_NTXDESC - Configured number of Tx descriptors. Default: 18

+	CONFIG_NET_NRXDESC - Configured number of Rx descriptors. Default: 18

+	CONFIG_NET_PRIORITY - Ethernet interrupt priority.  The is default is

+	  the higest priority.

+	CONFIG_NET_WOL - Enable Wake-up on Lan (not fully implemented).

+	CONFIG_NET_REGDEBUG - Enabled low level register debug.  Also needs

+	  CONFIG_DEBUG.

+	CONFIG_NET_DUMPPACKET - Dump all received and transmitted packets.

+	  Also needs CONFIG_DEBUG.

+

+  LPC17xx USB Device Configuration

+

+	CONFIG_LPC17_USBDEV_FRAME_INTERRUPT

+	  Handle USB Start-Of-Frame events. 

+	  Enable reading SOF from interrupt handler vs. simply reading on demand.

+	  Probably a bad idea... Unless there is some issue with sampling the SOF

+	  from hardware asynchronously.

+	CONFIG_LPC17_USBDEV_EPFAST_INTERRUPT

+	  Enable high priority interrupts.  I have no idea why you might want to

+	  do that

+	CONFIG_LPC17_USBDEV_NDMADESCRIPTORS

+	  Number of DMA descriptors to allocate in SRAM.

+	CONFIG_LPC17_USBDEV_DMA

+	  Enable lpc17xx-specific DMA support

+

+  LPC17xx USB Host Configuration (the LPCXpresso does not support USB Host)

+

+    CONFIG_USBHOST_OHCIRAM_SIZE

+      Total size of OHCI RAM (in AHB SRAM Bank 1)

+    CONFIG_USBHOST_NEDS

+    CONFIG_USBHOST_TDBUFSIZE

+      Size of one transfer descriptor buffer

+    CONFIG_USBHOST_IOBUFSIZE

+      Size of one end-user I/O buffer.  This can be zero if the

+      application can guarantee that all end-user I/O buffers

+      reside in AHB SRAM.

+

+Configurations

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

+

+Each LPCXpresso configuration is maintained in a sudirectory and can be

+selected as follow:

+

+	cd tools

+	./configure.sh lpcxpresso-lpc1768/<subdir>

+	cd -

+	. ./setenv.sh

+

+Where <subdir> is one of the following:

+

+  ostest:

+    This configuration directory, performs a simple OS test using

+    examples/ostest.

+# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
+#   inheritance on mutexes and semaphores. 
+# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
+#   inheritance is enabled.  It defines the maximum number of
+#   different threads (minus one) that can take counts on a
+#   semaphore with priority inheritance support.  This may be 
+#   set to zero if priority inheritance is disabled OR if you
+#   are only using semaphores as mutexes (only one holder) OR
+#   if no more than two threads participate using a counting
+#   semaphore.
+# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
+#   then this setting is the maximum number of higher priority
+#   threads (minus 1) than can be waiting for another thread
+#   to release a count on a semaphore.  This value may be set
+#   to zero if no more than one thread is expected to wait for
+#   a semaphore.
+# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
+#   by task_create() when a new task is started.  If set, all
+#   files/drivers will appear to be closed in the new task.
+# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
+#   three file descriptors (stdin, stdout, stderr) by task_create()
+#   when a new task is started. If set, all files/drivers will
+#   appear to be closed in the new task except for stdin, stdout,
+#   and stderr.
+# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
+#   desciptors by task_create() when a new task is started. If
+#   set, all sockets will appear to be closed in the new task.
+# CONFIG_NXFLAT. Enable support for the NXFLAT binary format.
+#  This format will support execution of NuttX binaries located
+#  in a ROMFS filesystem (see examples/nxflat).
+# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
+#  handle delayed processing from interrupt handlers.  This feature
+#  is required for some drivers but, if there are not complaints,
+#  can be safely disabled.  The worker thread also performs
+#  garbage collection -- completing any delayed memory deallocations
+#  from interrupt handlers.  If the worker thread is disabled,
+#  then that clean will be performed by the IDLE thread instead
+#  (which runs at the lowest of priority and may not be appropriate
+#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
+#  is enabled, then the following options can also be used:
+# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
+#  thread.  Default: 50
+# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
+#  work in units of microseconds.  Default: 50*1000 (50 MS).
+# CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
+#  thread.  Default: CONFIG_IDLETHREAD_STACKSIZE.
+# CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
+#  the worker thread.  Default: 4

+ *

+ *      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).
