+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 NuttX buildroot toolchain. However,
+ the make system is setup to default to use the devkitARM toolchain. To use
+ the CodeSourcery, devkitARM or Raisonance GNU 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 are not using CONFIG_STM32_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), 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 (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/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 <some-dir>/nuttx.
+
+ cd tools
+ ./configure.sh stm3210e-eval/<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.
+
+DFU and JTAG
+============
+
+ Enbling Support for the DFU Bootloader
+ --------------------------------------
+ The linker files in these projects can be configured to indicate that you
+ will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
+ loader or via some JTAG emulator. You can specify the DFU bootloader by
+ adding the following line:
+
+ CONFIG_STM32_DFU=y
+
+ to your .config file. Most of the configurations in this directory are set
+ up to use the DFU loader.
+
+ If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
+ of FLASH (0x08000000) but will be offset to 0x08003000. This offset is needed
+ to make space for the DFU loader and 0x08003000 is where the DFU loader expects
+ to find new applications at boot time. If you need to change that origin for some
+ other bootloader, you will need to edit the file(s) ld.script.dfu for each
+ configuration.
+
+ The DFU SE PC-based software is available from the STMicro website,
+ http://www.st.com. General usage instructions:
+
+ 1. Convert the NuttX Intel Hex file (nuttx.ihx) into a special DFU
+ file (nuttx.dfu)... see below for details.
+ 2. Connect the STM3210E-EVAL board to your computer using a USB
+ cable.
+ 3. Start the DFU loader on the STM3210E-EVAL board. You do this by
+ resetting the board while holding the "Key" button. Windows should
+ recognize that the DFU loader has been installed.
+ 3. Run the DFU SE program to load nuttx.dfu into FLASH.
+
+ What if the DFU loader is not in FLASH? The loader code is available
+ inside of the Demo dirctory of the USBLib ZIP file that can be downloaded
+ from the STMicro Website. You can build it using RIDE (or other toolchains);
+ you will need a JTAG emulator to burn it into FLASH the first time.
+
+ In order to use STMicro's built-in DFU loader, you will have to get
+ the NuttX binary into a special format with a .dfu extension. The
+ DFU SE PC_based software installation includes a file "DFU File Manager"
+ conversion program that a file in Intel Hex format to the special DFU
+ format. When you successfully build NuttX, you will find a file called
+ nutt.ihx in the top-level directory. That is the file that you should
+ provide to the DFU File Manager. You will need to rename it to nuttx.hex
+ in order to find it with the DFU File Manager. You will end up with
+ a file called nuttx.dfu that you can use with the STMicro DFU SE program.
+
+ Enabling JTAG
+ -------------
+ If you are not using the DFU, then you will probably also need to enable
+ JTAG support. By default, all JTAG support is disabled but there NuttX
+ configuration options to enable JTAG in various different ways.
+
+ These configurations effect the setting of the SWJ_CFG[2:0] bits in the AFIO
+ MAPR register. These bits are used to configure the SWJ and trace alternate function I/Os. The SWJ (SerialWire JTAG) supports JTAG or SWD access to the
+ Cortex debug port. The default state in this port is for all JTAG support
+ to be disable.
+
+ CONFIG_STM32_JTAG_FULL_ENABLE - sets SWJ_CFG[2:0] to 000 which enables full
+ SWJ (JTAG-DP + SW-DP)
+
+ CONFIG_STM32_JTAG_NOJNTRST_ENABLE - sets SWJ_CFG[2:0] to 001 which enable
+ full SWJ (JTAG-DP + SW-DP) but without JNTRST.
+
+ CONFIG_STM32_JTAG_SW_ENABLE - sets SWJ_CFG[2:0] to 010 which would set JTAG-DP
+ disabled and SW-DP enabled
+
+ The default setting (none of the above defined) is SWJ_CFG[2:0] set to 100
+ which disable JTAG-DP and SW-DP.
+
+OpenOCD
+=======
+
+I have also used OpenOCD with the STM3210E-EVAL. In this case, I used
+the Olimex USB ARM OCD. See the script in configs/stm3210e-eval/tools/oocd.sh
+for more information. Using the script:
+
+1) Start the OpenOCD GDB server
+
+ cd <nuttx-build-directory>
+ configs/stm3210e-eval/tools/oocd.sh $PWD
+
+2) Load Nuttx
+
+ cd <nuttx-built-directory>
+ arm-none-eabi-gdb nuttx
+ gdb> target remote localhost:3333
+ gdb> mon reset
+ gdb> mon halt
+ gdb> load nuttx
+
+3) Running NuttX
+
+ gdb> mon reset
+ gdb> c
+
+LEDs
+====
+
+The STM3210E-EVAL board has four LEDs labeled LD1, LD2, LD3 and LD4 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
+ ---------------- ----------------------- ----- ----- ----- -----
+ 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.
+
+Temperature Sensor
+==================
+
+Support for the on-board LM-75 temperature sensor is available. This supported
+has been verified, but has not been included in any of the available the
+configurations. To set up the temperature sensor, add the following to the
+NuttX configuration file
+
+ CONFIG_I2C=y
+ CONFIG_I2C_LM75=y
+
+Then you can implement logic like the following to use the temperature sensor:
+
+ #include <nuttx/sensors/lm75.h>
+ #include <arch/board/board.h>
+
+ ret = stm32_lm75initialize("/dev/temp"); /* Register the temperature sensor */
+ fd = open("/dev/temp", O_RDONLY); /* Open the temperature sensor device */
+ ret = ioctl(fd, SNIOC_FAHRENHEIT, 0); /* Select Fahrenheit */
+ bytesread = read(fd, buffer, 8*sizeof(b16_t)); /* Read temperature samples */
+
+More complex temperature sensor operations are also available. See the IOCTAL
+commands enumerated in include/nuttx/sensors/lm75.h. Also read the descriptions
+of the stm32_lm75initialize() and stm32_lm75attach() interfaces in the
+arch/board/board.h file (sames as configs/stm3210e-eval/include/board.h).
+
+RTC
+===
+
+ The STM32 RTC may configured using the following settings.
+
+ CONFIG_RTC - Enables general support for a hardware RTC. Specific
+ architectures may require other specific settings.
+ CONFIG_RTC_HIRES - The typical RTC keeps time to resolution of 1
+ second, usually supporting a 32-bit time_t value. In this case,
+ the RTC is used to &quot;seed&quot; the normal NuttX timer and the
+ NuttX timer provides for higher resoution time. If CONFIG_RTC_HIRES
+ is enabled in the NuttX configuration, then the RTC provides higher
+ resolution time and completely replaces the system timer for purpose of
+ date and time.
+ CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the
+ frequency of the high resolution RTC must be provided. If CONFIG_RTC_HIRES
+ is not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
+ CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an alarm.
+ A callback function will be executed when the alarm goes off
+
+ In hi-res mode, the STM32 RTC operates only at 16384Hz. Overflow interrupts
+ are handled when the 32-bit RTC counter overflows every 3 days and 43 minutes.
+ A BKP register is incremented on each overflow interrupt creating, effectively,
+ a 48-bit RTC counter.
+
+ In the lo-res mode, the RTC operates at 1Hz. Overflow interrupts are not handled
+ (because the next overflow is not expected until the year 2106.
+
+ WARNING: Overflow interrupts are lost whenever the STM32 is powered down. The
+ overflow interrupt may be lost even if the STM32 is powered down only momentarily.
+ Therefore hi-res solution is only useful in systems where the power is always on.
+
+STM3210E-EVAL-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
+
+ CONFIG_ARCH_CHIP=stm32
+
+ CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+ chip:
+
+ CONFIG_ARCH_CHIP_STM32F103ZET6
+
+ 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=stm3210e_eval (for the STM3210E-EVAL development board)
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_STM3210E_EVAL=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 STM32F103Z 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.
+

+
+ 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,..,8
+ CONFIG_STM32_TIMn_ADC Reserve timer n for use by ADC, n=1,..,8
+ CONFIG_STM32_TIMn_ADCm Reserve timer n to trigger ADCm, n=1,..,8, m=1,..,3
+ CONFIG_STM32_TIMn_DAC Reserve timer n for use by DAC, n=1,..,8
+ CONFIG_STM32_TIMn_DACm Reserve timer n to trigger DACm, n=1,..,8, 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.
+

+ but without JNTRST.
+ CONFIG_STM32_JTAG_SW_ENABLE - Set JTAG-DP disabled and SW-DP enabled
+
+ STM32F103Z specific device driver settings

+ 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_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_SDIO_WIDTH_D1_ONLY - Select 1-bit transfer mode. Default:
+ 4-bit transfer mode.
+
+ STM3210E-EVAL CAN Configuration
+
+ CONFIG_CAN - Enables CAN support (one or both of CONFIG_STM32_CAN1 or
+ CONFIG_STM32_CAN2 must also be defined)
+ CONFIG_CAN_EXTID - Enables support for the 29-bit extended ID. Default
+ Standard 11-bit IDs.

+ adjustable backlight will be provided using timer 1 to generate
+ various pulse widthes. The granularity of the settings is
+ determined by CONFIG_LCD_MAXPOWER. If CONFIG_LCD_PWM (or
+ CONFIG_STM32_TIM1) is not defined, then a simple on/off backlight
+ is provided.
+ CONFIG_LCD_RDSHIFT - When reading 16-bit gram data, there appears
+ to be a shift in the returned data. This value fixes the offset.
+ Default 5.
+
+ The LCD driver dynamically selects the LCD based on the reported LCD
+ ID value. However, code size can be reduced by suppressing support for
+ individual LCDs using:
+
+ CONFIG_STM32_AM240320_DISABLE
+ CONFIG_STM32_SPFD5408B_DISABLE
+ CONFIG_STM32_R61580_DISABLE
+
+Configurations
+==============
+
+Each STM3210E-EVAL configuration is maintained in a sudirectory and
+can be selected as follow:
+
+ cd tools
+ ./configure.sh stm3210e-eval/<subdir>
+ cd -
+ . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+ buttons:
+ --------
+
+ Uses apps/examples/buttons to exercise STM3210E-EVAL buttons and
+ button interrupts.
+
+ CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows
+
+ composite
+ ---------
+
+ This configuration exercises a composite USB interface consisting
+ of a CDC/ACM device and a USB mass storage device. This configuration
+ uses apps/examples/composite.
+
+ nsh and nsh2:
+ ------------
+ Configure the NuttShell (nsh) located at examples/nsh.
+
+ Differences between the two NSH configurations:
+
+ =========== ======================= ================================
+ nsh nsh2
+ =========== ======================= ================================
+ Toolchain: NuttX buildroot for Codesourcery for Windows (1)
+ Linux or Cygwin (1,2)
+ ----------- ----------------------- --------------------------------
+ Loader: DfuSe DfuSe
+ ----------- ----------------------- --------------------------------
+ Serial Debug output: USART1 Debug output: USART1
+ Console: NSH output: USART1 NSH output: USART1 (3)
+ ----------- ----------------------- --------------------------------
+ microSD Yes Yes

+ =========== ======================= ================================
+
+ (1) You will probably need to modify nsh/setenv.sh or nsh2/setenv.sh
+ to set up the correct PATH variable for whichever toolchain you
+ may use.
+ (2) Since DfuSe is assumed, this configuration may only work under
+ Cygwin without modification.
+ (3) When any other device other than /dev/console is used for a user
+ interface, (1) linefeeds (\n) will not be expanded to carriage return
+ / linefeeds \r\n). You will need to configure your terminal program
+ to account for this. And (2) input is not automatically echoed so
+ you will have to turn local echo on.
+ (4) Microsoft holds several patents related to the design of
+ long file names in the FAT file system. Please refer to the
+ details in the top-level COPYING file. Please do not use FAT
+ long file name unless you are familiar with these patent issues.
+ (5) When built as an NSH add-on command (CONFIG_EXAMPLES_USBMSC_BUILTIN=y),
+ Caution should be used to assure that the SD drive is not in use when
+ the USB storage device is configured. Specifically, the SD driver
+ should be unmounted like:
+
+ nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Card is mounted in NSH
+ ...
+ nsh> umount /mnd/sdcard # Unmount before connecting USB!!!
+ nsh> msconn # Connect the USB storage device
+ ...
+ nsh> msdis # Disconnect USB storate device
+ nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Restore the mount
+
+ Failure to do this could result in corruption of the SD card format.
+
+ nx:
+ ---
+ An example using the NuttX graphics system (NX). This example
+ focuses on general window controls, movement, mouse and keyboard
+ input.
+
+ CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows
+ CONFIG_LCD_RPORTRAIT=y : 240x320 reverse portrait
+
+ nxlines:
+ ------
+ Another example using the NuttX graphics system (NX). This
+ example focuses on placing lines on the background in various
+ orientations.
+
+ CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows
+ CONFIG_LCD_RPORTRAIT=y : 240x320 reverse portrait
+
+ nxtext:
+ ------
+ Another example using the NuttX graphics system (NX). This
+ example focuses on placing text on the background while pop-up
+ windows occur. Text should continue to update normally with
+ or without the popup windows present.
+
+ CONFIG_STM32_BUILDROOT=y : NuttX buildroot under Linux or Cygwin
+ CONFIG_LCD_RPORTRAIT=y : 240x320 reverse portrait
+
+ NOTE: When I tried building this example with the CodeSourcery
+ tools, I got a hardfault inside of its libgcc. I haven't
+ retested since then, but beware if you choose to change the
+ toolchain.
+
+ 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_BUILDROOT=y : NuttX buildroot under Linux or Cygwin
+
+ RIDE
+ ----
+ This configuration builds a trivial bring-up binary. It is
+ useful only because it words with the RIDE7 IDE and R-Link debugger.
+
+ CONFIG_STM32_RAISONANCE=y : Raisonance RIDE7 under Windows
+
+ usbserial:
+ ---------
+ This configuration directory exercises the USB serial class
+ driver at examples/usbserial. See examples/README.txt for
+ more information.
+
+ CONFIG_STM32_BUILDROOT=y : NuttX buildroot under Linux or Cygwin
+
+ USB debug output can be enabled as by changing the following
+ settings in the configuration file:
+
+ -CONFIG_DEBUG=n
+ -CONFIG_DEBUG_VERBOSE=n
+ -CONFIG_DEBUG_USB=n
+ +CONFIG_DEBUG=y
+ +CONFIG_DEBUG_VERBOSE=y
+ +CONFIG_DEBUG_USB=y
+
+ -CONFIG_EXAMPLES_USBSERIAL_TRACEINIT=n
+ -CONFIG_EXAMPLES_USBSERIAL_TRACECLASS=n

+ +CONFIG_EXAMPLES_USBSERIAL_TRACECLASS=y
+ +CONFIG_EXAMPLES_USBSERIAL_TRACETRANSFERS=y
+ +CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER=y
+ +CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS=y
+
+ By default, the usbserial example uses the Prolific PL2303
+ serial/USB converter emulation. The example can be modified
+ to use the CDC/ACM serial class by making the following changes
+ to the configuration file:
+
+ -CONFIG_PL2303=y
+ +CONFIG_PL2303=n
+
+ -CONFIG_CDCACM=n
+ +CONFIG_CDCACM=y
+
+ The example can also be converted to use the alternative
+ USB serial example at apps/examples/usbterm by changing the
+ following:
+
+ -CONFIGURED_APPS += examples/usbserial
+ +CONFIGURED_APPS += examples/usbterm
+
+ In either the original appconfig file (before configuring)
+ or in the final apps/.config file (after configuring).
+
+ usbstorage:
+ ----------
+ This configuration directory exercises the USB mass storage
+ class driver at examples/usbstorage. See examples/README.txt for
+ more information.
