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, ok + 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_SAM34_CODESOURCERYW=y : CodeSourcery under Windows + CONFIG_SAM34_CODESOURCERYL=y : CodeSourcery under Linux + CONFIG_SAM34_DEVKITARM=y : devkitARM under Windows + CONFIG_SAM34_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default) + + If you are not using CONFIG_SAM34_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 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 (There is a simple RIDE project + in the RIDE subdirectory). + + 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/sam34, + 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/sam34/sam_vectors.S. You may need to build NuttX + one time from the Cygwin command line in order to obtain the pre-built + startup object needed by RIDE. + +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 /nuttx. + + cd tools + ./configure.shsam4l-xplained/ + + 2. Download the latest buildroot package into + + 3. unpack the buildroot tarball. The resulting directory may + have versioning information on it like buildroot-x.y.z. If so, + rename /buildroot-x.y.z to /buildroot. + + 4. cd /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. Modify the Make.defs file to use the OABI conventions: + + +CROSSDEV = arm-nuttx-elf- + +ARCHCPUFLAGS = -mtune=cortex-m3 -march=armv7-m -mfloat-abi=soft + +NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections + -CROSSDEV = arm-nuttx-eabi- + -ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft + -NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections + +NXFLAT Toolchain +^^^^^^^^^^^^^^^^ + + If you are *not* using the NuttX buildroot toolchain and you want to use + the NXFLAT tools, then you will still have to build a portion of the buildroot + tools -- just the NXFLAT tools. 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 /nuttx. + + cd tools + ./configure.sh lpcxpresso-lpc1768/ + + 2. Download the latest buildroot package into + + 3. unpack the buildroot tarball. The resulting directory may + have versioning information on it like buildroot-x.y.z. If so, + rename /buildroot-x.y.z to /buildroot. + + 4. cd /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 +^^^^ + There are three LEDs on board the SAM4L Xplained Pro board: The EDBG + controls two of the LEDs, a power LED and a status LED. There is only + one user controllable LED, a yellow LED labeled LED0 near the SAM4L USB + connector. + + This LED is controlled by PC07 and LED0 can be activated by driving the + PC07 to GND. + + When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will + control LED0 as follows: + + SYMBOL Meaning LED0 + ------------------- ----------------------- ------ + LED_STARTED NuttX has been started OFF + LED_HEAPALLOCATE Heap has been allocated OFF + LED_IRQSENABLED Interrupts enabled OFF + LED_STACKCREATED Idle stack created ON + LED_INIRQ In an interrupt N/C + LED_SIGNAL In a signal handler N/C + LED_ASSERTION An assertion failed N/C + LED_PANIC The system has crashed FLASH + + Thus is LED0 is statically on, NuttX has successfully booted and is, + apparently, running normmally.
