OpenOCD + requires a configuration file. I keep the one I used last here: + + configs/lm4f120-launchpad/tools/lm4f120-launchpad.cfg + + However, the "correct" configuration script to use with OpenOCD may + change as the features of OpenOCD evolve. So you should at least + compare that lm4f120-launchpad.cfg file with configuration files in + /usr/share/openocd/scripts. As of this writing, the configuration + files of interest were: + + /usr/share/openocd/scripts/interface/luminary.cfg + /usr/share/openocd/scripts/board/ek-lm3s6965.cfg + /usr/share/openocd/scripts/target/stellaris.cfg + + There is also a script on the tools/ directory that I use to start + the OpenOCD daemon on my system called oocd.sh. That script will + probably require some modifications to work in another environment: + + - Possibly the value of OPENOCD_PATH and TARGET_PATH + - It assumes that the correct script to use is the one at + configs/lm4f120-launchpad/tools/lm4f120-launchpad.cfg + + Starting OpenOCD + + Then you should be able to start the OpenOCD daemon like: + + configs/lm4f120-launchpad/tools/oocd.sh $PWD + + Connecting GDB + + Once the OpenOCD daemon has been started, you can connect to it via + GDB using the following GDB command: + + arm-nuttx-elf-gdb + (gdb) target remote localhost:3333 + + NOTE: The name of your GDB program may differ. For example, with the + CodeSourcery toolchain, the ARM GDB would be called arm-none-eabi-gdb. + + After starting GDB, you can load the NuttX ELF file: + + (gdb) symbol-file nuttx + (gdb) monitor reset + (gdb) monitor halt + (gdb) load nuttx + + NOTES: + 1. Loading the symbol-file is only useful if you have built NuttX to + include debug symbols (by setting CONFIG_DEBUG_SYMBOLS=y in the + .config file). + 2. The MCU must be halted prior to loading code using 'mon reset' + as described below. + + OpenOCD will support several special 'monitor' commands. These + GDB commands will send comments to the OpenOCD monitor. Here + are a couple that you will need to use: + + (gdb) monitor reset + (gdb) monitor halt + + NOTES: + 1. The MCU must be halted using 'mon halt' prior to loading code. + 2. Reset will restart the processor after loading code. + 3. The 'monitor' command can be abbreviated as just 'mon'. + +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 NuttX buildroot Toolchain (default, see below), + 2. The CodeSourcery GNU toolchain, + 3. The devkitARM GNU toolchain, + 4. The Atollic toolchain, or + 5. The Code Red toolchain + + All testing has been conducted using the Buildroot toolchain for Cygwin/Linux. + To use a different toolchain, you simply need to add one of the following + configuration options to your .config (or defconfig) file: + + CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default) + CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows or Cygwin + CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux + CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=y : The Atollic toolchain under Windows or Cygwin + CONFIG_ARMV7M_TOOLCHAIN_CODEREDW=y : The Code Red toolchain under Windows + CONFIG_ARMV7M_TOOLCHAIN_CODEREDL=y : The Code Red toolchain under Linux + + CONFIG_ARMV7M_OABI_TOOLCHAIN=y : If you use an older, OABI buildroot toolchain + + 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 Code Red (for Windows) + 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 + + 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/lm, + 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/lm/lm_vectors.S. + +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 lm4f120-launchpad/<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.

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. + +LEDs +^^^^ + The LM32F120 has a single RGB LED. If CONFIG_ARCH_LEDS is defined, then + support for the LaunchPad LEDs will be included in the build. See: + + - configs/lm4f120-launchpad/include/board.h - Defines LED constants, types and + prototypes the LED interface functions. + + - configs/lm4f120-launchpad/src/lm4f120-launchpad.h - GPIO settings for the LEDs. + + - configs/lm4f120-launchpad/src/up_leds.c - LED control logic. + + OFF: + - OFF means that the OS is still initializing. Initialization is very fast so + if you see this at all, it probably means that the system is hanging up + somewhere in the initialization phases. + + GREEN or GREEN-ish + - This means that the OS completed initialization. + + Bluish: + - Whenever and interrupt or signal handler is entered, the BLUE LED is + illuminated and extinguished when the interrupt or signal handler exits. + This will add a BLUE-ish tinge to the LED. + + Redish: + - If a recovered assertion occurs, the RED component will be illuminated + briefly while the assertion is handled. You will probably never see this. + + Flashing RED: + - In the event of a fatal crash, the BLUE and GREEN components will be + extinguished and the RED component will FLASH at a 2Hz rate. + +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: + + MODE DEBUG FUNCTION USE SELECTED BY + 1 Internal ICDI Debug on-board LM4F120 Default Mode + microcontroller over USB + interface. + 2 ICDI out to JTAG/SWD The EVB is used as a USB Connecting to an external + header to SWD/JTAG interface to target and starting debug + an external target. software.
