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
|
|
=====================
|
|
|
|
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 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
|
|
|
|
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 EABI "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 stm3220g-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-eabi-defconfig-4.6.3 .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
|
|
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 toochain; instead use the GCC 4.3.3 OABI toolchain.
|
|
See instructions below.
|
|
|
|
NuttX OABI "buildroot" Toolchain
|
|
================================
|
|
|
|
The older, OABI buildroot toolchain is also available. To use the OABI
|
|
toolchain:
|
|
|
|
1. When building the buildroot toolchain, either (1) modify the cortexm3-eabi-defconfig-4.6.3
|
|
configuration to use EABI (using 'make menuconfig'), or (2) use an exising OABI
|
|
configuration such as cortexm3-defconfig-4.3.3
|
|
|
|
2. Modify the Make.defs file to use the OABI conventions:
|
|
|
|
+CROSSDEV = arm-nuttx-elf-
|
|
+ARCHCPUFLAGS = -mtune=cortex-m3 -march=armv7-m -mfloat-abi=soft
|
|
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections
|
|
-CROSSDEV = arm-nuttx-eabi-
|
|
-ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
|
|
-NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
|
|
|
|
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 SourceForge download site
|
|
(https://sourceforge.net/projects/nuttx/files/).
|
|
|
|
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. Edit setenv.h, if necessary, so that the PATH variable includes
|
|
the path to the newly builtNXFLAT binaries.
|
|
|
|
Ethernet
|
|
========
|
|
|
|
The Ethernet driver is configured to use the MII interface:
|
|
|
|
Board Jumper Settings:
|
|
|
|
Jumper Description
|
|
JP8 To enable MII, JP8 should not be fitted.
|
|
JP6 2-3: Enable MII interface mode
|
|
JP5 2-3: Provide 25 MHz clock for MII or 50 MHz clock for RMII by MCO at PA8
|
|
SB1 Not used with MII
|
|
|
|
LEDs
|
|
====
|
|
|
|
The STM3220G-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.
|
|
|
|
PWM
|
|
===
|
|
|
|
The STM3220G-Eval has no real on-board PWM devices, but the board can be
|
|
configured to output a pulse train using timer output pins. The following
|
|
pins have been use to generate PWM output (see board.h for some other
|
|
candidates):
|
|
|
|
TIM4 CH2. Pin PD13 is used by the FSMC (FSMC_A18) and is also connected
|
|
to the Motor Control Connector (CN5) just for this purpose. If FSMC is
|
|
not enabled, then FSMC_A18 will not be used (and will be tri-stated from
|
|
the LCD).
|
|
|
|
CONFIGURATION:
|
|
|
|
CONFIG_STM32_TIM4=y
|
|
CONFIG_PWM=n
|
|
CONFIG_PWM_PULSECOUNT=n
|
|
CONFIG_STM32_TIM4_PWM=y
|
|
CONFIG_STM32_TIM4_CHANNEL=2
|
|
|
|
ACCESS:
|
|
|
|
Daughterboard Extension Connector, CN3, pin 32
|
|
Ground is available on CN3, pin1
|
|
|
|
NOTE: TIM4 hardware will not support pulse counting.
|
|
|
|
TIM8 CH4: Pin PC9 is used by the microSD card (MicroSDCard_D1) and I2S
|
|
(I2S_CKIN) but can be completely disconnected from both by opening JP16.
|
|
|
|
CONFIGURATION:
|
|
|
|
CONFIG_STM32_TIM8=y
|
|
CONFIG_PWM=n
|
|
CONFIG_PWM_PULSECOUNT=y
|
|
CONFIG_STM32_TIM8_PWM=y
|
|
CONFIG_STM32_TIM8_CHANNEL=4
|
|
|
|
ACCESS:
|
|
|
|
Daughterboard Extension Connector, CN3, pin 17
|
|
Ground is available on CN3, pin1
|
|
|
|
CAN
|
|
===
|
|
|
|
Connector 10 (CN10) is DB-9 male connector that can be used with CAN1 or CAN2.
|
|
|
|
JP10 connects CAN1_RX or CAN2_RX to the CAN transceiver
|
|
JP3 connects CAN1_TX or CAN2_TX to the CAN transceiver
|
|
|
|
CAN signals are then available on CN10 pins:
|
|
|
|
CN10 Pin 7 = CANH
|
|
CN10 Pin 2 = CANL
|
|
|
|
Mapping to STM32 GPIO pins:
|
|
|
|
PD0 = FSMC_D2 & CAN1_RX
|
|
PD1 = FSMC_D3 & CAN1_TX
|
|
PB13 = ULPI_D6 & CAN2_TX
|
|
PB5 = ULPI_D7 & CAN2_RX
|
|
|
|
Configuration Options:
|
|
|
|
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.
|
|
CONFIG_CAN_FIFOSIZE - The size of the circular buffer of CAN messages.
|
|
Default: 8
|
|
CONFIG_CAN_NPENDINGRTR - The size of the list of pending RTR requests.
|
|
Default: 4
|
|
|
|
CONFIG_STM32_CAN1 - Enable support for CAN1
|
|
CONFIG_CAN1_BAUD - CAN1 BAUD rate. Required if CONFIG_STM32_CAN1 is defined.
|
|
CONFIG_STM32_CAN2 - Enable support for CAN2
|
|
CONFIG_CAN2_BAUD - CAN1 BAUD rate. Required if CONFIG_STM32_CAN2 is defined.
|
|
CONFIG_CAN_TSEG1 - The number of CAN time quanta in segment 1. Default: 6
|
|
CONFIG_CAN_TSEG2 - the number of CAN time quanta in segment 2. Default: 7
|
|
CONFIG_CAN_REGDEBUG - If CONFIG_DEBUG is set, this will generate an
|
|
dump of all CAN registers.
|
|
|
|
FSMC SRAM
|
|
=========
|
|
|
|
On-board SRAM
|
|
-------------
|
|
|
|
A 16 Mbit SRAM is connected to the STM32F407IGH6 FSMC bus which shares the same
|
|
I/Os with the CAN1 bus. Jumper settings:
|
|
|
|
JP1: Connect PE4 to SRAM as A20
|
|
JP2: onnect PE3 to SRAM as A19
|
|
|
|
JP3 and JP10 must not be fitted for SRAM and LCD application. JP3 and JP10
|
|
select CAN1 or CAN2 if fitted; neither if not fitted.
|
|
|
|
The on-board SRAM can be configured by setting
|
|
|
|
CONFIG_STM32_FSMC=y
|
|
CONFIG_STM32_FSMC_SRAM=y
|
|
CONFIG_HEAP2_BASE=0x64000000
|
|
CONFIG_HEAP2_SIZE=2097152
|
|
CONFIG_MM_REGIONS=2
|
|
|
|
Configuration Options
|
|
---------------------
|
|
|
|
Internal SRAM is available in all members of the STM32 family. In addition
|
|
to internal SRAM, SRAM may also be available through the FSMC. In order to
|
|
use FSMC SRAM, the following additional things need to be present in the
|
|
NuttX configuration file:
|
|
|
|
CONFIG_STM32_FSMC=y : Enables the FSMC
|
|
CONFIG_STM32_FSMC_SRAM=y : Indicates that SRAM is available via the
|
|
FSMC (as opposed to an LCD or FLASH).
|
|
CONFIG_HEAP2_BASE : The base address of the SRAM in the FSMC
|
|
address space
|
|
CONFIG_HEAP2_SIZE : The size of the SRAM in the FSMC
|
|
address space
|
|
CONFIG_MM_REGIONS : Must be set to a large enough value to
|
|
include the FSMC SRAM
|
|
|
|
SRAM Configurations
|
|
-------------------
|
|
There are 2 possible SRAM configurations:
|
|
|
|
Configuration 1. System SRAM (only)
|
|
CONFIG_MM_REGIONS == 1
|
|
Configuration 2. System SRAM and FSMC SRAM
|
|
CONFIG_MM_REGIONS == 2
|
|
CONFIG_STM32_FSMC_SRAM defined
|
|
|
|
I/O Expanders
|
|
=============
|
|
|
|
The STM3220G-EVAL has two STMPE811QTR I/O expanders on board both connected to
|
|
the STM32 via I2C1. They share a common interrupt line: PI2.

In addition to internal SRAM, SRAM may also be available through the FSMC.
|
|
In order to use FSMC SRAM, the following additional things need to be
|
|
present in the NuttX configuration file:
|
|

CONFIG_STM32_FSMC_SRAM - Indicates that SRAM is available via the
|
|
FSMC (as opposed to an LCD or FLASH).

|
|
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)
|
|
CONFIG_STM32_JTAG_NOJNTRST_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)

Configurations
|
|
==============
|
|
|
|
Each STM3220G-EVAL configuration is maintained in a sudirectory and
|
|
can be selected as follow:
|
|
|
|
cd tools
|
|
./configure.sh stm3220g-eval/<subdir>
|
|
cd -
|
|
. ./setenv.sh
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
dhcpd:
|
|
-----
|
|
|
|
This builds the DCHP server using the apps/examples/dhcpd application
|
|
(for execution from FLASH.) See apps/examples/README.txt for information
|
|
about the dhcpd example. The server address is 10.0.0.1 and it serves
|
|
IP addresses in the range 10.0.0.2 through 10.0.0.17 (all of which, of
|
|
course, are configurable).
|
|
|
|
CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows

|
using the STM32's Ethernet controller. It uses apps/examples/nettest to excercise the
|
|
TCP/IP network.
|
|
|
|
CONFIG_EXAMPLES_NETTEST_SERVER=n : Target is configured as the client
|
|
CONFIG_EXAMPLES_NETTEST_PERFORMANCE=y : Only network performance is verified.
|
|
CONFIG_EXAMPLES_NETTEST_IPADDR=(10<<24|0<<16|0<<8|2) : Target side is IP: 10.0.0.2
|
|
CONFIG_EXAMPLES_NETTEST_DRIPADDR=(10<<24|0<<16|0<<8|1) : Host side is IP: 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.
|
|
|
|
2. This example supports the ADC test (apps/examples/adc) but this must
|
|
be manually enabled by selecting:

|
|
support simply uncomment the following lines in the appconfig file (before
|
|
configuring) or in the apps/.config file (after configuring):
|
|
|
|
#CONFIGURED_APPS += netutils/ftpc
|
|
#CONFIGURED_APPS += examples/ftpc
|
|
|
|
6. This example can support an FTP server. In order to build in FTP server
|
|
support simply uncomment the following lines in the appconfig file (before
|
|
configuring) or in the apps/.config file (after configuring):
|
|
|
|
#CONFIGURED_APPS += netutils/ftpd
|
|
#CONFIGURED_APPS += examples/ftpd
|
|
|
|
And enable poll() support in the NuttX configuration file:
|
|
|
|
CONFIG_DISABLE_POLL=n
|
|
|
|
7. This example supports the watchdog timer test (apps/examples/watchdog)
|
|
but this must be manually enabled by selecting:
|
|
|
|
CONFIG_WATCHDOG=y : Enables watchdog timer driver support
|
|
CONFIG_STM32_WWDG=y : Enables the WWDG timer facility, OR
|
|
CONFIG_STM32_IWDG=y : Enables the IWDG timer facility (but not both)
|
|
|
|
The WWDG watchdog is driven off the (fast) 42MHz PCLK1 and, as result,
|
|
has a maximum timeout value of 49 milliseconds. For WWDG watchdog, you
|
|
should also add the fillowing to the configuration file:
|
|
|
|
CONFIG_EXAMPLES_WATCHDOG_PINGDELAY=20
|
|
CONFIG_EXAMPLES_WATCHDOG_TIMEOUT=49
|
|
|
|
The IWDG timer has a range of about 35 seconds and should not be an issue.
|
|
|
|
7. Adding LCD and graphics support:
|

|
board is that you cannot have both a UART-based NSH console and SDIO support.
|
|
The nsh2 differs from the nsh configuration in the following ways:
|
|
|
|
-CONFIG_STM32_USART3=y : USART3 is disabled
|
|
+ CONFIG_STM32_USART3=n
|
|
|
|
-CONFIG_STM32_SDIO=n : SDIO is enabled
|
|
+CONFIG_STM32_SDIO=y
|
|
|
|
Logically, these are the only differences: This configuration has SDIO (and
|
|
the SD card) enabled and the serial console disabled. There is ONLY a
|
|
Telnet console!.
|
|
|
|
There are some special settings to make life with only a Telnet
|
|
|
|
CONFIG_SYSLOG=y - Enables the System Logging feature.
|
|
CONFIG_RAMLOG=y - Enable the RAM-based logging feature.
|
|
CONFIG_RAMLOG_CONSOLE=y - Use the RAM logger as the default console.
|
|
This means that any console output from non-Telnet threads will
|
|
go into the circular buffer in RAM.
|
|
CONFIG_RAMLOG_SYSLOG - This enables the RAM-based logger as the
|
|
system logger. This means that (1) in addition to the console
|
|
output from other tasks, ALL of the debug output will also to
|
|
to the circular buffer in RAM, and (2) NSH will now support a
|
|
command called 'dmesg' that can be used to dump the RAM log.
|
|
|
|
There are a few other configuration differences as necessary to support
|
|
this different device configuration. Just the do the 'diff' if you are
|
|
curious.
|
|
|
|
NOTES:
|
|
1. See the notes for the nsh configuration. Most also apply to the nsh2
|
|
configuration.
|
|
|
|
2. RS-232 is disabled, but Telnet is still available for use as a console.
|
|
Since RS-232 and SDIO use the same pins (one controlled by JP22), RS232
|
|
and SDIO cannot be used concurrently.
|
|
|
|
3. This configuration requires that jumper JP22 be set to enable SDIO
|
|
operation. To enable MicroSD Card, which shares same I/Os with RS-232,
|
|
JP22 is not fitted.
|
|
|
|
4. In order to use SDIO without overruns, DMA must be used.
|
|
|
|
5. Another SDIO/DMA issue. This one is probably a software bug. This is
|
|
the bug as stated in the TODO list:
|
|
|
|
"If you use a large I/O buffer to access the file system, then the
|
|
MMCSD driver will perform multiple block SD transfers. With DMA
|
|
ON, this seems to result in CRC errors detected by the hardware
|
|
during the transfer. Workaround: CONFIG_MMCSD_MULTIBLOCK_DISABLE=y"
|
|
|
|
For this reason, CONFIG_MMCSD_MULTIBLOCK_DISABLE=y appears in the defconfig
|
|
file.
|
|
|
|
6. Another DMA-related concern. I see this statement in the reference
|
|
manual: "The burst configuration has to be selected in order to respect
|
|
the AHB protocol, where bursts must not cross the 1 KB address boundary
|
|
because the minimum address space that can be allocated to a single slave
|
|
is 1 KB. This means that the 1 KB address boundary should not be crossed
|
|
by a burst block transfer, otherwise an AHB error would be generated,
|
|
that is not reported by the DMA registers."
|
|
|
|
There is nothing in the DMA driver to prevent this now.

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
|
|
|
|
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/nuttx/tools
|
|
$ ./configure.sh stm3220g-eval/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/nuttx
|
|
...
|
|
|
|
5. Build the NxWM library
|
|
|
|
$ cd ~/nuttx-code/NxWidgets/nxwm
|
|
$ make TOPDIR=~/nuttx-code/nuttx
|
|
...
|
|
|
|
6. Built NuttX with the installed unit test as the application
|
|
|
|
$ cd ~/nuttx-code/nuttx
|
|
$ make
|
|
|
|
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
|
|
|
|
telnetd:
|
|
--------
|
|
|
|
A simple test of the Telnet daemon(see apps/netutils/README.txt,
|
|
apps/examples/README.txt, and apps/examples/telnetd). This is
|
|
the same daemon that is used in the nsh configuration so if you
|
|
use NSH, then you don't care about this. This test is good for
|
|
testing the Telnet daemon only because it works in a simpler
|
|
environment than does the nsh configuration.
