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.
|
||||
|
||||
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.
|
||||
|
||||
MKDEP = $(TOPDIR)/tools/mknulldeps.sh
|
||||
|
||||
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.
|
||||
|
||||
$ (cd tools; ./configure.sh nucleo-f4x1re/f401-nsh)
|
||||
$ make qconfig
|
||||
$ V=1 make context all 2>&1 | tee mout
|
||||
|
||||
Use the f411-nsh configuration if you have the Nucleo-F411RE board.
|
||||
|
||||
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.
|
||||
|
||||
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-nxflat .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Make sure that the PATH variable includes the path to the newly built
|
||||
NXFLAT binaries.

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-L432kc. The NUCLEO window will
|
||||
close then re-open and the Nucleo-L432KC will be running the new code.

Hardware
|
||||
========
|
||||
|
||||
Buttons
|
||||
-------
|
||||
B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32
|
||||
microcontroller.
|
||||
|
||||
LEDs
|
||||
----
|
||||
The Nucleo F401RE and Nucleo F411RE provide 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.

|
||||
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_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.
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
nsh:
|
||||
---------
|
||||
Configures the NuttShell (nsh) located at apps/examples/nsh for the
|
||||
Nucleo-F401RE 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:

* The external functions, stm32l4_spi1/2select and stm32l4_spi1/2status must be

* and status methods of the SPI interface defined by struct spi_ops_s (see

* include/nuttx/spi/spi.h). All other methods (including up_spiinitialize())
|

* are provided by common STM32 logic. To use this common SPI logic on your
|
||||
* board:
|
||||
*
|
||||
* 1. Provide logic in stm32l4_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide stm32l4_spi1/2select() and stm32l4_spi1/2status() 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).
