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_LM3S_CODESOURCERYW=y : CodeSourcery under Windows + CONFIG_LM3S_CODESOURCERYL=y : CodeSourcery under Linux + CONFIG_LM3S_DEVKITARM=y : devkitARM under Windows + CONFIG_LM3S_RAISONANCE=y : Raisonance RIDE7 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), 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 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 (There is a simple RIDE project + in the RIDE subdirectory). 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. 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 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 lm3s6965-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. + +Ethernet-Bootloader +^^^^^^^^^^^^^^^^^^^ + + Here are some notes about using the Luminary Ethernet boot-loader built + into the Stellaris LM3S6965 Evaluation Kit. + + Built-In Application: + + - The board has no fixed IP address but uses DHCP to get an address. + I used a D-link router; I can use a web browser to surf to the D-link + web page to get the address assigned by DHCP. + + - Then you can use this IP address in your browser to surf to the evaluation + board. It presents several interesting pages -- the most important is + the page called "Firmware Update". That page includes instructions on + how to download code to the evaluation board. + + - After you burn the first program, you lose this application. Then you + will probably be better off connected directly to the Stellaris LM3S6965 + Evaluation Kit or through a switch (The router caused problems for me + during downloads). + + Using the Ethernet Bootloader: + + - You will need the "LM Flash Programmer application". You can get that + program from the Luminary web site. There is a link on the LM3S6918 page. + + - Is there any documentation for using the bootloader? Yes and No: There + is an application note covering the bootloader on the Luminary site, but + it is not very informative. + + - Are there any special things I have to do in my code, other than setting + the origin to 0x0000:2000 (APP_START_ADDRESS)? No. The bootloader assumes + that you have a vector table at that address . The bootloader does the + following each time it boots (after you have downloaded the first valid + application): + + o The bootloader sets the vector table register to the APP_START_ADDRESS, + o It sets the stack pointer to the address at APP_START_ADDRESS, and then + o Jumps to the address at APP_START_ADDRESS+4. + + - You can force the bootloader to skip starting the application and stay + in the update mode. You will need to do this in order to download a new + application. You force the update mode by holding the user button on the + Stellaris LM3S6965 Evaluation Kit while resetting the board. The user + button is GPIOA, pin 6 (call FORCED_UPDATE_PIN in the bootloader code). + + - Note 1: I had to remove my D-Link router from the configuration in order + to use the LM Flash Programmer (the Bootloader issues BOOTP requests to + communicate with the LM Flash Programmer, my router was responding to + these BOOTP requests and hosing the download). It is safer to connect + via a switch or via an Ethernet switch. + + - Note 2: You don't need the router's DHCPD server in the download + configuration; the Luminary Flash Programmer has the capability of + temporarily assigning the IP address to the Stellaris LM3S6965 Evaluation + Kit via BOOTP. + +Stellaris LM3S6965 Evaluation Kit Configuration Options +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + + CONFIG_ARCH - Identifies the arch/ subdirectory.
