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.
GNU Toolchain Options
=====================
Toolchain Configurations
------------------------
The NuttX make system has been modified to support the following different
toolchain options.
1. The CodeSourcery GNU toolchain,
2. The Atollic Toolchain,
3. The devkitARM GNU toolchain,
4. Raisonance GNU toolchain, or
5. The NuttX buildroot Toolchain (see below).
All testing has been conducted using the CodeSourcery toolchain for Linux.
To use the Atollic, 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_ARMV7M_TOOLCHAIN_CODESOURCERYW=n : CodeSourcery under Windows
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux
CONFIG_ARMV7M_TOOLCHAIN_ATOLLIC=y : The Atollic toolchain under Windows
CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=n : devkitARM under Windows
CONFIG_ARMV7M_TOOLCHAIN_RAISONANCE=y : Raisonance RIDE7 under Windows
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=n : NuttX buildroot under Linux or Cygwin (default)
If you change the default toolchain, then you may also have to modify the
PATH environment variable to include the path to the toolchain binaries.
NOTE: 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:
V=1 make clean_context all 2>&1 |tee mout
An alias in your .bashrc file might make that less painful.
The Atollic "Pro" and "Lite" Toolchain
--------------------------------------
One problem that I had with the Atollic toolchains is that the provide a gcc.exe
and g++.exe in the same bin/ file as their ARM binaries. If the Atollic bin/ path
appears in your PATH variable before /usr/bin, then you will get the wrong gcc
when you try to build host executables. This will cause to strange, uninterpretable
errors build some host binaries in tools/ when you first make.
Also, the Atollic toolchains are the only toolchains that have built-in support for
the FPU in these configurations. If you plan to use the Cortex-M4 FPU, you will
need to use the Atollic toolchain for now. See the FPU section below for more
information.
The Atollic "Lite" Toolchain
----------------------------
The free, "Lite" version of the Atollic toolchain does not support C++ nor
does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
toolchain, you will have to set:
CONFIG_HAVE_CXX=n
In order to compile successfully. Otherwise, you will get errors like:
"C++ Compiler only available in TrueSTUDIO Professional"
The make may then fail in some of the post link processing because of some of
the other missing tools. The Make.defs file replaces the ar and nm with
the default system x86 tool versions and these seem to work okay. Disable all
of the following to avoid using objcopy:
CONFIG_RRLOAD_BINARY=n
CONFIG_INTELHEX_BINARY=n
CONFIG_MOTOROLA_SREC=n
CONFIG_RAW_BINARY=n
devkitARM
---------
The devkitARM toolchain includes a version of MSYS make. Make sure that the
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).
Using Sourcery CodeBench from http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/overview
Download and install the latest version (as of this writting it was
sourceryg++-2013.05-64-arm-none-eabi)
Import the project from git.
File->import->Git-URI, then import a Exiting code as a Makefile progject
from the working directory the git clone was done to.
Select the Sourcery CodeBench for ARM EABI. N.B. You must do one command line
build, before the make will work in CodeBench.
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 EABI "buildroot" Toolchain
================================
A GNU GCC-based toolchain is assumed. The PATH environment variable 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
Bitbucket download site (https://bitbucket.org/nuttx/buildroot/downloads/).
This GNU toolchain builds and executes in the Linux or Cygwin environment.
1. You must have already configured Nuttx in <some-dir>/nuttx.
$ tools/configure.sh nucleo-f446re/nsh
$ make qconfig
$ V=1 make context all 2>&1 | tee mout
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. Make sure 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 toolchain; instead use the GCC 4.3.3 EABI 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 Bitbucket download site
(https://bitbucket.org/nuttx/nuttx/downloads/).
This GNU toolchain builds and executes in the Linux or Cygwin environment.
1. You must have already configured Nuttx in <some-dir>/nuttx.
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-nxflat .config
6. make oldconfig
7. make
8. Make sure that the PATH variable includes the path to the newly built
NXFLAT binaries.
mbed
====
The Nucleo-F401RE includes boot loader from mbed:
https://mbed.org/platforms/ST-Nucleo-F401RE/
https://mbed.org/handbook/Homepage
Using the mbed loader:
1. Connect the Nucleo-F4x1RE to the host PC using the USB connector.
2. A new file system will appear called NUCLEO; open it with Windows
Explorer (assuming that you are using Windows).
3. Drag and drop nuttx.bin into the MBED window. This will load the
nuttx.bin binary into the Nucleo-F4x1RE. The NUCLEO window will
close then re-open and the Nucleo-F4x1RE will be running the new code.

Buttons
-------
B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32
microcontroller.
LEDs
----
The Nucleo F446RE provides a single user LED, LD2. LD2
is the green LED connected to Arduino signal D13 corresponding to MCU I/O
PA5 (pin 21) or PB13 (pin 34) depending on the STM32target.
- When the I/O is HIGH value, the LED is on.
- When the I/O is LOW, the LED is off.
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/sam_leds.c. The LEDs are used to encode OS-related
events as follows when the red LED (PE24) is available:
SYMBOL Meaning LD2
------------------- ----------------------- -----------
LED_STARTED NuttX has been started OFF
LED_HEAPALLOCATE Heap has been allocated OFF
LED_IRQSENABLED Interrupts enabled OFF
LED_STACKCREATED Idle stack created ON
LED_INIRQ In an interrupt No change
LED_SIGNAL In a signal handler No change
LED_ASSERTION An assertion failed No change
LED_PANIC The system has crashed Blinking
LED_IDLE MCU is is sleep mode Not used
Thus if LD2, NuttX has successfully booted and is, apparently, running
normally. If LD2 is flashing at approximately 2Hz, then a fatal error
has been detected and the system has halted.
Serial Consoles
===============
USART1
------
Pins and Connectors:
RXD: PA11 CN10 pin 14
PB7 CN7 pin 21
TXD: PA10 CN9 pin 3, CN10 pin 33
PB6 CN5 pin 3, CN10 pin 17
NOTE: You may need to edit the include/board.h to select different USART1
pin selections.
TTL to RS-232 converter connection:
Nucleo CN10 STM32F4x1RE
----------- ------------
Pin 21 PA9 USART1_RX *Warning you make need to reverse RX/TX on
Pin 33 PA10 USART1_TX some RS-232 converters
Pin 20 GND
Pin 8 U5V
To configure USART1 as the console:
CONFIG_STM32_USART1=y
CONFIG_USART1_SERIALDRIVER=y
CONFIG_USART1_SERIAL_CONSOLE=y
CONFIG_USART1_RXBUFSIZE=256
CONFIG_USART1_TXBUFSIZE=256
CONFIG_USART1_BAUD=115200
CONFIG_USART1_BITS=8
CONFIG_USART1_PARITY=0
CONFIG_USART1_2STOP=0
USART2
-----
Pins and Connectors:
RXD: PA3 CN9 pin 1 (See SB13, 14, 62, 63). CN10 pin 37
PD6
TXD: PA2 CN9 pin 2(See SB13, 14, 62, 63). CN10 pin 35
PD5
UART2 is the default in all of these configurations.
TTL to RS-232 converter connection:
Nucleo CN9 STM32F4x1RE
----------- ------------
Pin 1 PA3 USART2_RX *Warning you make need to reverse RX/TX on
Pin 2 PA2 USART2_TX some RS-232 converters
Solder Bridges. This configuration requires:
- SB62 and SB63 Closed: PA2 and PA3 on STM32 MCU are connected to D1 and D0
(pin 7 and pin 8) on Arduino connector CN9 and ST Morpho connector CN10
as USART signals. Thus SB13 and SB14 should be OFF.
- SB13 and SB14 Open: PA2 and PA3 on STM32F103C8T6 (ST-LINK MCU) are
disconnected to PA3 and PA2 on STM32 MCU.
To configure USART2 as the console:
CONFIG_STM32_USART2=y
CONFIG_USART2_SERIALDRIVER=y
CONFIG_USART2_SERIAL_CONSOLE=y
CONFIG_USART2_RXBUFSIZE=256
CONFIG_USART2_TXBUFSIZE=256
CONFIG_USART2_BAUD=115200
CONFIG_USART2_BITS=8
CONFIG_USART2_PARITY=0
CONFIG_USART2_2STOP=0
USART6
------
Pins and Connectors:
RXD: PC7 CN5 pin2, CN10 pin 19
PA12 CN10, pin 12
TXD: PC6 CN10, pin 4
PA11 CN10, pin 14
To configure USART6 as the console:
CONFIG_STM32_USART6=y
CONFIG_USART6_SERIALDRIVER=y
CONFIG_USART6_SERIAL_CONSOLE=y
CONFIG_USART6_RXBUFSIZE=256
CONFIG_USART6_TXBUFSIZE=256
CONFIG_USART6_BAUD=115200
CONFIG_USART6_BITS=8
CONFIG_USART6_PARITY=0
CONFIG_USART6_2STOP=0
Virtual COM Port
----------------
Yet another option is to use UART2 and the USB virtual COM port. This
option may be more convenient for long term development, but is painful
to use during board bring-up.
Solder Bridges. This configuration requires:
- SB62 and SB63 Open: PA2 and PA3 on STM32 MCU are disconnected to D1
and D0 (pin 7 and pin 8) on Arduino connector CN9 and ST Morpho
connector CN10.
- SB13 and SB14 Closed: PA2 and PA3 on STM32F103C8T6 (ST-LINK MCU) are
connected to PA3 and PA2 on STM32 MCU to have USART communication
between them. Thus SB61, SB62 and SB63 should be OFF.
Configuring USART2 is the same as given above.
Question: What BAUD should be configure to interface with the Virtual
COM port? 115200 8N1?
Default
-------
As shipped, SB62 and SB63 are open and SB13 and SB14 closed, so the
virtual COM port is enabled.
Shields
=======
RS-232 from Cutedigi.com
------------------------
Supports a single RS-232 connected via
Nucleo CN9 STM32F4x1RE Cutedigi
----------- ------------ --------
Pin 1 PA3 USART2_RX RXD
Pin 2 PA2 USART2_TX TXD
Support for this shield is enabled by selecting USART2 and configuring
SB13, 14, 62, and 63 as described above under "Serial Consoles"
Itead Joystick Shield
---------------------
See http://imall.iteadstudio.com/im120417014.html for more information
about this joystick.
Itead Joystick Connection:
--------- ----------------- ---------------------------------
ARDUINO ITEAD NUCLEO-F4x1
PIN NAME SIGNAL SIGNAL
--------- ----------------- ---------------------------------
D3 Button E Output PB3
D4 Button D Output PB5
D5 Button C Output PB4
D6 Button B Output PB10
D7 Button A Output PA8
D8 Button F Output PA9
D9 Button G Output PC7
A0 Joystick Y Output PA0 ADC1_0
A1 Joystick X Output PA1 ADC1_1
--------- ----------------- ---------------------------------
All buttons are pulled on the shield. A sensed low value indicates
when the button is pressed.
NOTE: Button F cannot be used with the default USART1 configuration
because PA9 is configured for USART1_RX by default. Use select
different USART1 pins in the board.h file or select a different
USART or select CONFIG_NUCLEO_F401RE_AJOY_MINBUTTONS which will
eliminate all but buttons A, B, and C.
Itead Joystick Signal interpretation:
--------- ----------------------- ---------------------------
BUTTON TYPE NUTTX ALIAS
--------- ----------------------- ---------------------------
Button A Large button A JUMP/BUTTON 3
Button B Large button B FIRE/BUTTON 2
Button C Joystick select button SELECT/BUTTON 1
Button D Tiny Button D BUTTON 6
Button E Tiny Button E BUTTON 7
Button F Large Button F BUTTON 4
Button G Large Button G BUTTON 5
--------- ----------------------- ---------------------------
Itead Joystick configuration settings:
System Type -> STM32 Peripheral Support
CONFIG_STM32_ADC1=y : Enable ADC1 driver support
Drivers
CONFIG_ANALOG=y : Should be automatically selected
CONFIG_ADC=y : Should be automatically selected
CONFIG_INPUT=y : Select input device support
CONFIG_AJOYSTICK=y : Select analog joystick support
There is nothing in the configuration that currently uses the joystick.
For testing, you can add the following configuration options to enable the
analog joystick example at apps/examples/ajoystick:
CONFIG_NSH_ARCHINIT=y
CONFIG_EXAMPLES_AJOYSTICK=y
CONFIG_EXAMPLES_AJOYSTICK_DEVNAME="/dev/ajoy0"
CONFIG_EXAMPLES_AJOYSTICK_SIGNO=13
STATUS:
2014-12-04:
- Without ADC DMA support, it is not possible to sample both X and Y
with a single ADC. Right now, only one axis is being converted.
- There is conflicts with some of the Arduino data pins and the
default USART1 configuration. I am currently running with USART1
but with CONFIG_NUCLEO_F401RE_AJOY_MINBUTTONS to eliminate the
conflict.
- Current showstopper: I appear to be getting infinite interrupts as
soon as joystick button interrupts are enabled.
Configurations
==============
nsh:
----
Configures the NuttShell (nsh) located at apps/examples/nsh for the
Nucleo-F446RE board. The Configuration enables the serial interfaces
on UART2. Support for builtin applications is enabled, but in the base
configuration no builtin applications are selected (see NOTES below).
NOTES:
1. This configuration uses the mconf-based configuration tool. To
change this configuration using that tool, you should:
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
see additional README.txt files in the NuttX tools repository.
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
2. By default, this configuration uses the CodeSourcery toolchain
for Linux. That can easily be reconfigured, of course.
CONFIG_HOST_LINUX=y : Builds under Linux
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery for Linux
3. Although the default console is USART2 (which would correspond to
the Virtual COM port) I have done all testing with the console
device configured for USART1 (see instruction above under "Serial
Consoles). I have been using a TTL-to-RS-232 converter connected
as shown below:

* Input Parameters:

* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initalization logic and the
* matching application logic. The value cold be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.

*
* Description:
* The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status
* must be provided by board-specific logic. They are implementations of
* the select and status methods of the SPI interface defined by struct
* spi_ops_s (see include/nuttx/spi/spi.h). All other methods (including
* stm32_spibus_initialize()) are provided by common STM32 logic. To use
* this common SPI logic on your board:
*
* 1. Provide logic in stm32_boardinitialize() to configure SPI chip
* select pins.
* 2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() 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 stm32_spibus_initialize() in your low level application
* initialization logic
* 4. The handle returned by stm32_spibus_initialize() 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).
