+
+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 because the Raisonance R-Link emulatator and some RIDE7 development tools
+ were used and those tools works only under Windows.
+
+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. Raisonance GNU toolchain, or
+ 4. The NuttX buildroot Toolchain (see below).
+
+ All testing has been conducted using the CodeSourcery toolchain for Windows. To use
+ the devkitARM, Raisonance GNU, or NuttX buildroot toolchain, you simply need to
+ add one of the following configuration options to your .config (or defconfig)
+ file:
+
+ CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows
+ CONFIG_STM32_CODESOURCERYL=y : CodeSourcery under Linux
+ CONFIG_STM32_DEVKITARM=y : devkitARM under Windows
+ CONFIG_STM32_RAISONANCE=y : Raisonance RIDE7 under Windows
+ CONFIG_STM32_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
+
+ If you change the default toolchain, 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), devkitARM, and Raisonance toolchains 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 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.
+
+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.
+
+ 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/stm32,
+ 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/stm32/stm32_vectors.S. With RIDE, I have to build NuttX
+ one time from the Cygwin command line in order to obtain the pre-built
+ startup object needed by RIDE.
+
+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 /nuttx.
+
+ cd tools
+ ./configure.sh stm32f4discovery/
+
+ 2. Download the latest buildroot package into
+
+ 3. unpack the buildroot tarball. The resulting directory may
+ have versioning information on it like buildroot-x.y.z. If so,
+ rename /buildroot-x.y.z to /buildroot.
+
+ 4. cd /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.
+
+LEDs
+====
+
+The stm32f4discovery board has four LEDs; green, organge, red and blue on the
+board.. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+defined. In that case, the usage by the board port is defined in
+include/board.h and src/up_leds.c. The LEDs are used to encode OS-related\
+events as follows:
+
+ SYMBOL Meaning LED1* LED2 LED3 LED4
+ green orange red blue
+ ------------------- ----------------------- ------- ------- ------- ------
+ LED_STARTED NuttX has been started ON OFF OFF OFF
+ LED_HEAPALLOCATE Heap has been allocated OFF ON OFF OFF
+ LED_IRQSENABLED Interrupts enabled ON ON OFF OFF
+ LED_STACKCREATED Idle stack created OFF OFF ON OFF
+ LED_INIRQ In an interrupt** ON N/C N/C OFF
+ LED_SIGNAL In a signal handler*** N/C ON N/C OFF
+ LED_ASSERTION An assertion failed ON ON N/C OFF
+ LED_PANIC The system has crashed N/C N/C N/C ON
+ LED_IDLE STM32 is is sleep mode (Optional, not used)
+
+ * If LED1, LED2, LED3 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 LED3 ON and LED1 faintly glowing. This faint glow
+ is because of timer interupts that result in the LED being illuminated
+ on a small proportion of the time.
+*** LED2 may also flicker normally if signals are processed.
+
+PWM
+===
+
+The stm32f4discovery has no real on-board PWM devices, but the board can be
+configured to output a pulse train using TIM4 CH2 on PD3. This pin is
+available next to the audio jack.
+
+stm32f4discovery-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_CORTEXM4=y
+
+ CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+ CONFIG_ARCH_CHIP=stm32
+
+ CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+ chip:
+
+ CONFIG_ARCH_CHIP_STM32F407IG=y
+
+ CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG - Enables special STM32 clock
+ configuration features.
+
+ CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=n
+
+ CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+ hence, the board that supports the particular chip or SoC.
+
+ CONFIG_ARCH_BOARD=stm32f4discovery (for the stm32f4discovery development board)
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_STM32F4_DISCOVERY=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 (SRAM in this case):
+
+ CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+ CONFIG_DRAM_START - The start address of installed DRAM
+
+ CONFIG_DRAM_START=0x20000000
+
+ CONFIG_DRAM_END - Last address+1 of installed RAM
+
+ CONFIG_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
+
+ CONFIG_ARCH_IRQPRIO - The STM3240xxx supports interrupt prioritization
+
+ CONFIG_ARCH_IRQPRIO=y
+
+ CONFIG_ARCH_FPU - The STM3240xxx supports a floating point unit (FPU)
+
+ CONFIG_ARCH_FPU=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.
+
+ Individual subsystems can be enabled:

+
+ Timer and I2C devices may need to the following to force power to be applied
+ unconditionally at power up. (Otherwise, the device is powered when it is
+ initialized).
+
+ CONFIG_STM32_FORCEPOWER
+
+ Timer devices may be used for different purposes. One special purpose is
+ to generate modulated outputs for such things as motor control. If CONFIG_STM32_TIMn
+ is defined (as above) then the following may also be defined to indicate that
+ the timer is intended to be used for pulsed output modulation, ADC conversion,
+ or DAC conversion. Note that ADC/DAC require two definition: Not only do you have
+ to assign the timer (n) for used by the ADC or DAC, but then you also have to
+ configure which ADC or DAC (m) it is assigned to.
+
+ CONFIG_STM32_TIMn_PWM Reserve timer n for use by PWM, n=1,..,14
+ CONFIG_STM32_TIMn_ADC Reserve timer n for use by ADC, n=1,..,14
+ CONFIG_STM32_TIMn_ADCm Reserve timer n to trigger ADCm, n=1,..,14, m=1,..,3
+ CONFIG_STM32_TIMn_DAC Reserve timer n for use by DAC, n=1,..,14
+ CONFIG_STM32_TIMn_DACm Reserve timer n to trigger DACm, n=1,..,14, m=1,..,2
+
+ For each timer that is enabled for PWM usage, we need the following additional
+ configuration settings:
+
+ CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
+
+ NOTE: The STM32 timers are each capable of generating different signals on
+ each of the four channels with different duty cycles. That capability is
+ not supported by this driver: Only one output channel per timer.
+
+ JTAG Enable settings (by default only SW-DP is enabled):
+
+ CONFIG_STM32_JTAG_FULL_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)
+ CONFIG_STM32_JTAG_NOJNTRST_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)
+ but without JNTRST.
+ CONFIG_STM32_JTAG_SW_ENABLE - Set JTAG-DP disabled and SW-DP enabled
+
+ STM3240xxx specific device driver settings
+
+ CONFIG_U[S]ARTn_SERIAL_CONSOLE - selects the USARTn (n=1,2,3) or UART
+ m (m=4,5) for the console and ttys0 (default is the USART1).
+ CONFIG_U[S]ARTn_RXBUFSIZE - Characters are buffered as received.
+ This specific the size of the receive buffer
+ CONFIG_U[S]ARTn_TXBUFSIZE - Characters are buffered before
+ being sent. This specific the size of the transmit buffer
+ CONFIG_U[S]ARTn_BAUD - The configure BAUD of the UART. Must be
+ CONFIG_U[S]ARTn_BITS - The number of bits. Must be either 7 or 8.
+ CONFIG_U[S]ARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+ CONFIG_U[S]ARTn_2STOP - Two stop bits
+
+ CONFIG_STM32_SPI_INTERRUPTS - Select to enable interrupt driven SPI
+ support. Non-interrupt-driven, poll-waiting is recommended if the
+ interrupt rate would be to high in the interrupt driven case.
+ CONFIG_STM32_SPI_DMA - Use DMA to improve SPI transfer performance.
+ Cannot be used with CONFIG_STM32_SPI_INTERRUPT.
+
+ CONFIG_SDIO_DMA - Support DMA data transfers. Requires CONFIG_STM32_SDIO
+ and CONFIG_STM32_DMA2.
+ CONFIG_SDIO_PRI - Select SDIO interrupt prority. Default: 128
+ CONFIG_SDIO_DMAPRIO - Select SDIO DMA interrupt priority.
+ Default: Medium
+ CONFIG_SDIO_WIDTH_D1_ONLY - Select 1-bit transfer mode. Default:
+ 4-bit transfer mode.
+
+Configurations
+==============
+
+Each stm32f4discovery configuration is maintained in a sudirectory and
+can be selected as follow:
+
+ cd tools
+ ./configure.sh stm32f4discovery/
+ cd -
+ . ./setenv.sh
+
+Where is one of the following:
+
+ ostest:
+ ------
+ This configuration directory, performs a simple OS test using
+ examples/ostest. By default, this project assumes that you are
+ using the DFU bootloader.
+
+ CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows
+
+ nsh:
+ ---
+ Configures the NuttShell (nsh) located at apps/examples/nsh. The
+ Configuration enables both the serial and telnet NSH interfaces.
+
+ CONFIG_STM32_CODESOURCERYL=y : CodeSourcery under Linux / Mac OS X
+
+ NOTES:
+ 1. This example supports the PWM test (apps/examples/pwm) but this must
+ be manually enabled by selecting:
+
+ CONFIG_PWM=y : Enable the generic PWM infrastructure
+ CONFIG_STM32_TIM4_PWM=y : Use TIM4 to generate PWM output
+
+ See also apps/examples/README.txt
+
+ Special PWM-only debug options:
+
+ CONFIG_DEBUG_PWM

+# CONFIG_ARCH_BOARD_name - for use in C code
+# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
+# CONFIG_BOARD_LOOPSPERMSEC - for delay loops
+# CONFIG_DRAM_SIZE - Describes the installed DRAM.
+# CONFIG_DRAM_START - The start address of DRAM (physical)
+# CONFIG_DRAM_END - Last address+1 of installed RAM
+# CONFIG_ARCH_IRQPRIO - The STM3240xxx supports interrupt prioritization
+# CONFIG_ARCH_FPU - The STM3240xxx supports a floating point unit (FPU)
+# (But, unfortunately, GCC does not support it).
+# 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
