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 toolchain, you simply need add one of the + following configuration options to your .config (or defconfig) file: + + CONFIG_LPC43_CODESOURCERYW=y : CodeSourcery under Windows + CONFIG_LPC43_CODESOURCERYL=y : CodeSourcery under Linux + CONFIG_LPC43_DEVKITARM=y : devkitARM under Windows + CONFIG_LPC43_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default) + + If you are not using CONFIG_LPC43_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 (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/lpc17xx, + 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/lpc17x/lpc17_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 lpc4330-xplorer/<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. + +LPC4330-Xplorer Configuration Options +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + + CONFIG_ARCH - Identifies the arch/ subdirectory.

The hidkbd +example can be used to test this interface. + +The NuttShell (NSH) lpc4330-xplorer can also be modified in order to support USB +host operations. To make these modifications, do the following: + +1. First configure to build the NSH configuration from the top-level + NuttX directory: + + cd tools + ./configure lpc4330-xplorer/nsh + cd .. + +2. Then edit the top-level .config file to enable USB host. Make the + following changes: + + CONFIG_LPC43_USBHOST=n + CONFIG_USBHOST=n + CONFIG_SCHED_WORKQUEUE=y + +When this change is made, NSH should be extended to support USB flash +devices. When a FLASH device is inserted, you should see a device +appear in the /dev (psuedo) directory. The device name should be +like /dev/sda, /dev/sdb, etc. The USB mass storage device, is present +it can be mounted from the NSH command line like: + + ls /dev + mount -t vfat /dev/sda /mnt/flash + +Files on the connect USB flash device should then be accessible under +the mountpoint /mnt/flash. + +Configurations +^^^^^^^^^^^^^^ + +Each LPC4330-Xplorer configuration is maintained in a sudirectory and can be selected +as follow: + + cd tools + ./configure.sh lpc4330-xplorer/<subdir> + cd - + . ./setenv.sh + +Where <subdir> is one of the following: + + hidkbd: + This configuration directory, performs a simple test of the USB host + HID keyboard class driver using the test logic in examples/hidkbd. + + nsh: + Configures the NuttShell (nsh) located at examples/nsh. The + Configuration enables only the serial NSH interfaces. See notes + above for enabling USB host support in this configuration. diff --git a/nuttx/configs/lpc4330-xplorer/include/board.h b/nuttx/configs/lpc4330-xplorer/include/board.h new file mode 100644 index 000000000..ce455630d --- /dev/null +++ b/nuttx/configs/lpc4330-xplorer/include/board.h @@ -0,0 +1,222 @@ +/**************************************************************************** + * configs/lpc4330-xplorer/include/board.h + * include/arch/board/board.h + * + * Copyright (C) 2012 Gregory Nutt.
