Transciever ON + B7 PB5 Transciever #OFF + +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. + + +Stellaris MDL-S2E Reference Design Configuration Options +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + + CONFIG_ARCH - Identifies the arch/ subdirectory.

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.
