+README for NuttX port to the Stellaris LMS36965 Evaluation Kit
+
+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 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 /nuttx.
+
+ cd tools
+ ./configure.sh lm3s6965-ek/
+
+ 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-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. This should
+ be set to:
+
+ CONFIG_ARCH=arm
+
+ CONFIG_ARCH_family - For use in C code:
+
+ CONFIG_ARCH_ARM=y
+
+ CONFIG_ARCH_architecture - For use in C code:
+
+ CONFIG_ARCH_CORTEXM3=y
+
+ CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+ CONFIG_ARCH_CHIP=lm3s
+
+ CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+ chip:
+
+ CONFIG_ARCH_CHIP_LM3S6965
+
+ CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+ hence, the board that supports the particular chip or SoC.
+
+ CONFIG_ARCH_BOARD=lm3s6965-ek (for the Stellaris LM3S6965 Evaluation Kit)
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_LM3S6965EK
+
+ CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+ of delay loops
+
+ CONFIG_ENDIAN_BIG - define if big endian (default is little
+ endian)
+
+ CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+ CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+ CONFIG_DRAM_START - The start address of installed DRAM
+
+ CONFIG_DRAM_START=0x20000000
+
+ CONFIG_DRAM_END - Last address+1 of installed RAM
+
+ CONFIG_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
+
+ CONFIG_ARCH_IRQPRIO - The LM3S6918 supports interrupt prioritization
+
+ CONFIG_ARCH_IRQPRIO=y
+
+ CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+ have LEDs
+
+ CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+ stack. If defined, this symbol is the size of the interrupt
+ stack in bytes. If not defined, the user task stacks will be
+ used during interrupt handling.
+
+ CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+ CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to board architecture.
+
+ CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+ cause a 100 second delay during boot-up. This 100 second delay
+ serves no purpose other than it allows you to calibratre
+ CONFIG_ARCH_LOOPSPERMSEC. You simply use a stop watch to measure
+ the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+ the delay actually is 100 seconds.
+
+ LM3S6818 specific device driver settings
+
+ CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+ console and ttys0 (default is the UART0).
+ CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+ This specific the size of the receive buffer
+ CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+ being sent. This specific the size of the transmit buffer
+ CONFIG_UARTn_BAUD - The configure BAUD of the UART. Must be
+ CONFIG_UARTn_BITS - The number of bits. Must be either 7 or 8.
+ CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity

+
+ CONFIG_SSI0_DISABLE - Select to disable support for SSI0
+ CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+ CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
+ Poll-waiting is recommended if the interrupt rate would be to
+ high in the interrupt driven case.
+ CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
+ emptying the Rx FIFO. If the SPI frequency is high and this
+ value is large, then larger values of this setting may cause
+ Rx FIFO overrun errors. Default: half of the Tx FIFO size (4).
+
+ CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
+ to build the LM3S Ethernet driver
+ CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
+ CONFIG_LM3S_BOARDMAC - If the board-specific logic can provide
+ a MAC address (via lm3s_ethernetmac()), then this should be selected.
+ CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
+ CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
+ CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding
+ CONFIG_LM3S_MULTICAST - Set to enable multicast frames

+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris LM3S6965 Evaluation Kit configuration is maintained in a
+sudirectory and can be selected as follow:
+
+ cd tools
+ ./configure.sh lm3s6965-ek/
+ cd -
+ . ./setenv.sh
+
+Where is one of the following:
+
+ nettest:
+ This configuration directory may be used to enable networking using the
+ LM3S6918's Ethernet controller. It uses examples/nettest to excercise the
+ TCP/IP network.
+
+ httpd:
+ This builds the uIP web server example using the examples/uip application
+ (for execution from FLASH). See examples/README.txt for information
+ about ostest.
+
+ nsh:
+ Configures the NuttShell (nsh) located at examples/nsh. The
+ Configuration enables both the serial and telnetd NSH interfaces.
+
+ ostest:
+ This configuration directory, performs a simple OS test using
+ examples/ostest.
+
+By default, all of these examples are built to be used with the Luminary
+Ethernet Bootloader (you can change the ld.script file in any of these
+sub-directories to change that configuration).

+ * The external functions, lm3s_spiselect and lm3s_spistatus must be provided
+ * by board-specific logic. The are implementations of the select and status
+ * methods SPI interface defined by struct spi_ops_s (see include/nuttx/spi.h).
+ * All othermethods (including up_spiinitialize()) are provided by common
+ * logic. To use this common SPI logic on your board:
+ *
+ * 1. Provide lm3s_spiselect() and lm3s_spistatus() functions in your
+ * board-specific logic. This function will perform chip selection and
+ * status operations using GPIOs in the way your board is configured.
+ * 2. Add a call to up_spiinitialize() in your low level initialization
+ * logic
+ * 3. The handle returned by up_spiinitialize() may then be used to bind the
+ * SPI driver to higher level logic (e.g., calling
+ * mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ * the SPI MMC/SD driver).
