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
|
2012-10-06 19:29:36 +02:00
|
|
|
CONFIG_STM32_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
2011-12-17 21:07:22 +01:00
|
|
|
|
|
|
|
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.
|
|
|

MKDEP = $(TOPDIR)/tools/mknulldeps.sh
|
2011-12-17 21:07:22 +01:00
|
|
|
|
|
|
|
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 EABI "buildroot" Toolchain
|
|
|
|
================================
|
2011-12-17 21:07:22 +01:00
|
|
|
|
|
|
|
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
|
2012-09-17 21:33:42 +02:00
|
|
|
SourceForge download site (https://sourceforge.net/projects/nuttx/files/buildroot/).
|
2011-12-17 21:07:22 +01:00
|
|
|
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 hymini-stm32v/<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
|
|
|
|
|
2012-10-06 19:29:36 +02:00
|
|
|
5. cp configs/cortexm3-eabi-defconfig-4.6.3 .config
|
2011-12-17 21:07:22 +01:00
|
|
|
|
|
|
|
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
|
2012-10-06 19:29:36 +02:00
|
|
|
details PLUS some special instructions that you will need to follow if you are
|
2011-12-17 21:07:22 +01:00
|
|
|
building a Cortex-M3 toolchain for Cygwin under Windows.
|
|
|
|
|
2012-10-10 21:58:57 +02:00
|
|
|
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
|
|
|
|
|
2012-10-10 19:01:23 +02:00
|
|
|
2. Modify the Make.defs file to use the OABI conventions:
|
2012-10-06 19:29:36 +02:00
|
|
|
|
|
|
|
+CROSSDEV = arm-nuttx-elf-
|
|
|
|
+ARCHCPUFLAGS = -mtune=cortex-m3 -march=armv7-m -mfloat-abi=soft
|
2012-10-10 19:01:23 +02:00
|
|
|
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections
|
2012-10-06 19:29:36 +02:00
|
|
|
-CROSSDEV = arm-nuttx-eabi-
|
|
|
|
-ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
|
2012-10-10 19:01:23 +02:00
|
|
|
-NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
|
2012-10-06 19:29:36 +02:00

|
|
|
|
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/).

ST Bootloader
|
|
|
|
=============
|
|
|
|
|
|
|
|
A bootloader code is available in an internal boot ROM memory (called
|
|
|
|
'system memory' in STM documentation) in all STM32 MCUs. For the F103xx
|
|
|
|
this bootloader can be used to upload & flash a firmware image through
|
|
|
|
the USART1.
|

|
|
|
|
2013-05-14 16:39:03 +02:00
|
|
|
Notes:
|
|
|
|
|
|
|
|
- The bootloader is activated by the BOOT0 / BOOT1 pins after a MCU reset.
|
|
|
|
See STM application note 2606 for more details.
|
|
|
|
- On the hymini-stm32 board the USART1 is connected to a PL2303
|
|
|
|
USB<->serial converter.
|
|
|
|
|
|
|
|
To enter bootloader mode in the hymini-stm32 board:
|
|
|
|
|
|
|
|
- Press the 'boot0' button (located next to 'reset' button)
|
|
|
|
- While boot0 button is pressed, reset the board through the reset button.
|
|
|
|
- Once you pressed / released the 'reset' button, the MCU has (re)started
|
|
|
|
in bootloader mode (and you can then release the boot0 button).
|
|
|
|
|
|
|
|
A flash utility must be used on your development workstation to upload / flash
|
|
|
|
a firmware image. (The 'stm32flash' open source tool, available at
|
|
|
|
http://stm32flash.googlecode.com/ has been used sucessfully).

LEDs
|
|
|
|
====
|
|
|
|
|
|
|
|
The HY-MiniSTM32 board provides only two controlable LEDs labeled LED1 and LED2.
|
|
|
|
Usage of these LEDs is defined in include/board.h and src/up_leds.c.
|
|
|
|
They are encoded as follows:
|
|
|
|
|
2013-05-14 16:39:03 +02:00

|
|
|
|
|
|
|
|

|
|
|
|
** LED1 is turned off during interrrupt.

|
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 "seed" 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.
|
2013-05-14 16:39:03 +02:00
|
|
|
CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an alarm.
|
2011-12-17 21:07:22 +01:00
|
|
|
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.

configuration tool. To change their configuration using that tool, you
|
|
|
|
should:
|
|
|
|
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
|
|
and misc/tools/
|
|
|
|
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
|
|
reconfiguration process.
|
|
|
|
|
|
|
|
- All configurations use a generic GNU EABI toolchain for Linux by
|
|
|
|
default.
|
|
|
|
|
|
|
|
- They are all configured to generate a binary image that can be flashed
|
|
|
|
through the STM32 internal bootloader.

(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.
|
2013-05-14 16:39:03 +02:00
|
|
|
(2) When any other device other than /dev/console is used for a user
|
2011-12-17 21:07:22 +01:00
|
|
|
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.

(3) Microsoft holds several patents related to the design of
|
2011-12-17 21:07:22 +01:00
|
|
|
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.

(4) When built as an NSH add-on command (CONFIG_NSH_BUILTIN_APPS=y),
|
2011-12-17 21:07:22 +01:00
|
|
|
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.
|

(5) Option CONFIG_NSH_ARCHINIT must be enabled in order to call the SDIO slot
|
|
|
|
initialization code.

usbnsh:

-------
|
|
|

|
|
|
|
This is another NSH example. If differs from other 'nsh' configurations
|
|
|
|
in that this configurations uses a USB serial device for console I/O.
|
|
|
|
|
|
|
|
NOTES:
|
|
|
|
|
|
|
|
1. This configuration does have UART2 output enabled and set up as
|
|
|
|
the system logging device:
|
|
|
|
|
|
|
|
CONFIG_SYSLOG=y : Enable output to syslog, not console
|
|
|
|
CONFIG_SYSLOG_CHAR=y : Use a character device for system logging
|
|
|
|
CONFIG_SYSLOG_DEVPATH="/dev/ttyS0" : UART2 will be /dev/ttyS0
|
|
|
|
|
|
|
|
However, there is nothing to generate SYLOG output in the default
|
|
|
|
configuration so nothing should appear on UART2 unless you enable
|
|
|
|
some debug output or enable the USB monitor.
|
|
|
|
|
|
|
|
2. Enabling USB monitor SYSLOG output. If tracing is enabled, the USB
|
|
|
|
device will save encoded trace output in in-memory buffer; if the
|
|
|
|
USB monitor is enabled, that trace buffer will be periodically
|
|
|
|
emptied and dumped to the system loggin device (UART2 in this
|
|
|
|
configuraion):
|
|
|
|
|
|
|
|
CONFIG_USBDEV_TRACE=y : Enable USB trace feature
|
|
|
|
CONFIG_USBDEV_TRACE_NRECORDS=128 : Buffer 128 records in memory
|
|
|
|
CONFIG_NSH_USBDEV_TRACE=n : No builtin tracing from NSH
|
|
|
|
CONFIG_NSH_ARCHINIT=y : Automatically start the USB monitor
|
|
|
|
CONFIG_SYSTEM_USBMONITOR=y : Enable the USB monitor daemon
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_STACKSIZE=2048 : USB monitor daemon stack size
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_PRIORITY=50 : USB monitor daemon priority
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_INTERVAL=2 : Dump trace data every 2 seconds
|
|
|
|
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_TRACEINIT=y : Enable TRACE output
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_TRACECLASS=y
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_TRACETRANSFERS=y
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_TRACECONTROLLER=y
|
|
|
|
CONFIG_SYSTEM_USBMONITOR_TRACEINTERRUPTS=y
|
|
|
|
|
|
|
|
|
|
|
|
Using the Prolifics PL2303 Emulation
|
|
|
|
------------------------------------
|
|
|
|
You could also use the non-standard PL2303 serial device instead of
|
|
|
|
the standard CDC/ACM serial device by changing:
|
|
|
|
|
|
|
|
CONFIG_CDCACM=y : Disable the CDC/ACM serial device class
|
|
|
|
CONFIG_CDCACM_CONSOLE=y : The CDC/ACM serial device is NOT the console
|
|
|
|
CONFIG_PL2303=y : The Prolifics PL2303 emulation is enabled
|
|
|
|
CONFIG_PL2303_CONSOLE=y : The PL2303 serial device is the console
|
