Development Environment
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Either Linux, Mac OS X 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 GCC on
|
||||
Mac OS X.
|
||||
|
||||
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. The NuttX buildroot Toolchain (see below).
|
||||
|
||||
To use a specific toolchain, you simply need to add one of the following
|
||||
configuration options to your .config (or defconfig) file:
|
||||
|
||||
CONFIG_LM3S_CODESOURCERYW=y : CodeSourcery under Windows
|
||||
CONFIG_LM3S_CODESOURCERYL=y : CodeSourcery under Linux or on Mac OS X.
|
||||
CONFIG_LM3S_DEVKITARM=y : devkitARM under Windows
|
||||
CONFIG_LM3S_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
||||
|
||||
If you are not using CONFIG_LM3S_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) and devkitARM 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
|
||||
|
||||
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.
|
||||
|
||||
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/lm3s,
|
||||
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/lm3s/lm3s_vectors.S.
|
||||
|
||||
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/project/showfiles.php?group_id=189573).
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
This port was tested with tools built using summon-arm-toolchain; available
|
||||
from https://github.com/esden/summon-arm-toolchain, however the buildroot
|
||||
instructions should apply for other platforms.
|
||||
|
||||
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
||||
|
||||
cd tools
|
||||
./configure.sh lm3s6432-s2e/<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.
|
||||
|
||||
NOTE: This is an OABI toolchain.

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.
|
||||
|
||||
There are configurations for disabling support for interrupts GPIO ports.
|
||||
GPIOH and GPIOJ must be disabled because they do not exist on the LM3S6432.
|
||||
Additional interrupt support can be disabled if desired to reduce memory
|
||||
footprint - GPIOs C-G are not pinned out on the MDL-S2E board.

LM3S6432 specific device driver settings
|
||||
|
||||
CONFIG_UARTn_DISABLE
|
||||
The TX and RX pins for UART1 share I/O pins with the TX and RX pins
|
||||
for SSI0. To avoid conflicts, only one of SSI0 and UART1 should
|
||||
be enabled in a configuration.
|
||||
CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
|
||||
console and ttys0 (default is UART1).
|
||||
CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
|
||||
This specific the size of the receive buffer
|
||||
CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
|
||||
being sent. This specific the size of the transmit buffer
|
||||
CONFIG_UARTn_BAUD - The configure BAUD of the UART. Must be
|
||||
CONFIG_UARTn_BITS - The number of bits. Must be either 7 or 8.
|
||||
CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
|
||||
CONFIG_UARTn_2STOP - Two stop bits
|
||||
|
||||
CONFIG_SSI0_DISABLE - Select to disable support for SSI0
|
||||
The TX and RX pins for SSI0 share I/O pins with the TX and RX pins
|
||||
for UART1. To avoid conflicts, only one of SSI0 and UART1 should
|
||||
be enabled in a configuration.
|
||||
CONFIG_SSI1_DISABLE - Select to disable support for SSI1
|
||||
Note that the LM3S6432 only has one SSI, so SSI1 should always be
|
||||
disabled.
|
||||
CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
|
||||
Poll-waiting is recommended if the interrupt rate would be to
|
||||
high in the interrupt driven case.
|
||||
CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
|
||||
emptying the Rx FIFO. If the SPI frequency is high and this
|
||||
value is large, then larger values of this setting may cause
|
||||
Rx FIFO overrun errors. Default: half of the Tx FIFO size (4).
|
||||
|
||||
CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
|
||||
to build the LM3S Ethernet driver
|
||||
CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
|
||||
CONFIG_LM3S_BOARDMAC - This should be set in order to use the
|
||||
MAC address configured in the flash USER registers.
|
||||
CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
|
||||
CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
|
||||
CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding
|
||||
CONFIG_LM3S_MULTICAST - Set to enable multicast frames
|
||||
CONFIG_LM3S_PROMISCUOUS - Set to enable promiscuous mode
|
||||
CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
|
||||
CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
|

Configurations
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
Each Stellaris MDL-S2E Reference Design configuration is maintained in a
|
||||
sudirectory and can be selected as follow:
|
||||
|
||||
cd tools
|
||||
./configure.sh lm3s6432-s2e/<subdir>
|
||||
cd -
|
||||
. ./setenv.sh
|
||||
|
||||
Where <subdir> is one of the following:
|
||||
|
||||
nsh:
|
||||
Configures the NuttShell (nsh) located at examples/nsh. The
|
||||
Configuration enables both the serial and telnetd NSH interfaces.
|
||||
|
||||
NOTE: As it is configured now, you MUST have a network connected.
|
||||
Otherwise, the NSH prompt will not come up because the Ethernet
|
||||
driver is waiting for the network to come up. That is probably
|
||||
a bug in the Ethernet driver behavior!
|
||||
|
||||
ostest:
|
||||
This configuration directory, performs a simple OS test using
|
||||
examples/ostest.
|
||||
|
||||
NOTE: as the configuration stands, ostest will hang during the
|
||||
semaphore test. This has not been debugged.
