|
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.
|
||||||
|
|
||||||
|
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).
|
||||||
|
|
||||||
|
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 or devkitARM, 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
|
||||||
|
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 not 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. Here are a few tip 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/cortexm3, 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.
|
||||||
|
|
||||||
|
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
||||||
|
|
||||||
|
cd tools
|
||||||
|
./configure.sh lm3s8962-ek/<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.

USB Device Controller Functions
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
Device Overview
|
||||||
|
|
||||||
|
An FT2232 device from Future Technology Devices International Ltd manages
|
||||||
|
USB-to-serial conversion. The FT2232 is factory configured by Luminary
|
||||||
|
Micro to implement a JTAG/SWD port (synchronous serial) on channel A and
|
||||||
|
a Virtual COM Port (VCP) on channel B. This feature allows two simultaneous
|
||||||
|
communications links between the host computer and the target device using
|
||||||
|
a single USB cable. Separate Windows drivers for each function are provided
|
||||||
|
on the Documentation and Software CD.
|
||||||
|
|
||||||
|
Debugging with JTAG/SWD
|
||||||
|
|
||||||
|
The FT2232 USB device performs JTAG/SWD serial operations under the control
|
||||||
|
of the debugger or the Luminary Flash Programmer. It also operate as an
|
||||||
|
In-Circuit Debugger Interface (ICDI), allowing debugging of any external
|
||||||
|
target board. Debugging modes:
|
||||||
|
|
||||||
|

|
||||||
|
the EVB.
|
||||||
|
|
||||||
|
Virtual COM Port
|
||||||
|
|
||||||
|
The Virtual COM Port (VCP) allows Windows applications (such as HyperTerminal)
|
||||||
|
to communicate with UART0 on the LM3S8962 over USB. Once the FT2232 VCP
|
||||||
|
driver is installed, Windows assigns a COM port number to the VCP channel.

Rx FIFO overrun errors. Default: half of the Tx FIFO size (4).
|
||||||
|
|
||||||
|
CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
|

|
CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
|
||||||
|
CONFIG_LM3S_BOARDMAC - If the board-specific logic can provide
|
||||||
|
a MAC address (via lm3s_ethernetmac()), then this should be selected.
|
||||||
|
CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
|

Configurations
|
||||||
|
^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
Each Stellaris LM3S8962 Evaluation Kit configuration is maintained in a
|
||||||
|
sudirectory and can be selected as follow:
|
||||||
|
|
||||||
|
cd tools
|
||||||
|
./configure.sh lm3s8962-ek/<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.

|
*
|

|
* 1. Provide lm3s_spiselect() and lm3s_spistatus() functions in your
|
||||||
|
* board-specific logic. This function will perform chip selection and
|
||||||
|
* status operations using GPIOs in the way your board is configured.
|

|
* 2. Add a call to up_spiinitialize() in your low level initialization
|
||||||
|
* logic
|
||||||
|
* 3. 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
