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 development tools that I used only work under Windows.
|
|
|
|
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).
|
|
|
|
Most testing has been conducted using the CodeSourcery toolchain for Windows and
|
|
that is the default toolchain in most configurations. 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_STM32_CODESOURCERYW=y : CodeSourcery under Windows
|
|
CONFIG_STM32_CODESOURCERYL=y : CodeSourcery under Linux
|
|
CONFIG_STM32_ATOLLIC_LITE=y : The free, "Lite" version of Atollic toolchain under Windows
|
|
CONFIG_STM32_ATOLLIC_PRO=y : The paid, "Pro" version of Atollic toolchain under Windows
|
|
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), Atollic, devkitARM, and Raisonance toolchains are
|
|
Windows native toolchains. The CodeSourcery (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
|
|
|
|
The CodeSourcery Toolchain (2009q1)
|
|
-----------------------------------
|
|
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.
|
|
|
|
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.
|
|
|
|
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).
|
|
|
|
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/projects/nuttx/files/buildroot/).
|
|
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 shenzhou/<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.
|
|
|
|
LEDs
|
|
====
|
|
|
|
The Shenzhou board has four LEDs labeled LED1, LED2, LED3 and LED4 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 LED1 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.
|
|
**** LED4 may not be available if RS-485 is also used. For RS-485, it will
|
|
then indicate the RS-485 direction.
|
|
|
|

CONFIG_STM32_CCMEXCLUDE - Exclude CCM SRAM from the HEAP
|
|
|

CONFIG_ARCH_IRQPRIO - The STM32107xxx 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 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 JTAG-DP and SW-DP are disabled):
|
|
|
|
CONFIG_STM32_JTAG_FULL_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)

Shenzhou LCD Hardware Configuration
|
|
|
|
The LCD driver supports the following LCDs on the STM324xG_EVAL board:
|
|
|
|
AM-240320L8TNQW00H (LCD_ILI9320 or LCD_ILI9321) OR
|
|
AM-240320D5TOQW01H (LCD_ILI9325)
|
|
|
|
Configuration options.
|
|
|
|
CONFIG_LCD_LANDSCAPE - Define for 320x240 display "landscape"
|
|
support. Default is this 320x240 "landscape" orientation
|
|
For the Shenzhou board, the edge opposite from the row of buttons
|
|
is used as the top of the display in this orientation.
|
|
CONFIG_LCD_RLANDSCAPE - Define for 320x240 display "reverse
|
|
landscape" support. Default is this 320x240 "landscape"
|
|
orientation

|
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_ILI9320_DISABLE (includes ILI9321)

Configurations
|
|
==============
|
|
|
|
Each Shenzhou configuration is maintained in a sudirectory and
|
|
can be selected as follow:
|
|
|
|
cd tools
|
|
./configure.sh shenzhou/<subdir>
|
|
cd -
|
|
. ./setenv.sh
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
nsh:
|
|
---
|
|
Configures the NuttShell (nsh) located at apps/examples/nsh. The
|
|
Configuration enables both the serial and telnet NSH interfaces.
|
|
|
|
CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows
|
|
CONFIG_NSH_DHCPC=n : DHCP is disabled
|
|
CONFIG_NSH_IPADDR=0x0a000002 : Target IP address 10.0.0.2
|
|
CONFIG_NSH_DRIPADDR=0x0a000001 : Host IP address 10.0.0.1
|
|
|
|
NOTES:
|
|
1. This example assumes that a network is connected. During its
|
|
initialization, it will try to negotiate the link speed. If you have
|
|
no network connected when you reset the board, there will be a long
|
|
delay (maybe 30 seconds?) before anything happens. That is the timeout
|
|
before the networking finally gives up and decides that no network is
|
|
available.

nxwm
|
|
----
|
|
This is a special configuration setup for the NxWM window manager
|
|
UnitTest. The NxWM window manager can be found here:
|
|
|
|
nuttx-code/NxWidgets/nxwm
|
|
|
|
The NxWM unit test can be found at:
|
|
|
|
nuttx-code/NxWidgets/UnitTests/nxwm
|
|
|
|
NOTE: JP6 selects between the touchscreen interrupt and the MII
|
|
interrupt. It should be positioned 1-2 to enable the touchscreen
|
|
interrupt.
|
|
|
|
Documentation for installing the NxWM unit test can be found here:
|
|
|
|
nuttx-code/NxWidgets/UnitTests/README.txt
|
|
|
|
Here is the quick summary of the build steps (Assuming that all of
|
|
the required packages are available in a directory ~/nuttx-code):
|
|
|
|
1. Intall the nxwm configuration
|
|
|
|
$ cd ~/nuttx-code/tools
|
|
$ ./configure.sh shenzhou/nxwm
|
|
|
|
2. Make the build context (only)
|
|
|
|
$ cd ..
|
|
$ . ./setenv.sh
|
|
$ make context
|
|
...
|
|
|
|
3. Install the nxwm unit test
|
|
|
|
$ cd ~/nuttx-code/NxWidgets
|
|
$ tools/install.sh ~/nuttx-code/apps nxwm
|
|
Creating symbolic link
|
|
- To ~/nuttx-code/NxWidgets/UnitTests/nxwm
|
|
- At ~/nuttx-code/apps/external
|
|
|
|
4. Build the NxWidgets library
|
|
|
|
$ cd ~/nuttx-code/NxWidgets/libnxwidgets
|
|
$ make TOPDIR=~/nuttx-code
|
|
...
|
|
|
|
5. Build the NxWM library
|
|
|
|
$ cd ~/nuttx-code/NxWidgets/nxwm
|
|
$ make TOPDIR=~/nuttx-code
|
|
...
|
|
|
|
6. Built NuttX with the installed unit test as the application
|
|
|
|
$ cd ~/nuttx-code
|
|
$ make
|
|
|
|
NOTE: Reading from the LCD is not currently supported by this
|
|
configuration. The hardware will support reading from the LCD
|
|
and drivers/lcd/ssd1289.c also supports reading from the LCD.
|
|
This limits some graphics capabilities.
|
|
|
|
Reading from the LCD is not supported only because it has not
|
|
been test. If you get inspired to test this feature, you can
|
|
turn the LCD read functionality on by setting:
|
|
|
|
-CONFIG_LCD_NOGETRUN=y
|
|
+# CONFIG_LCD_NOGETRUN is not set
|
|
|
|
-CONFIG_NX_WRITEONLY=y
|
|
+# CONFIG_NX_WRITEONLY is not set
|
|
|
