+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.
+
+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_LPC31XX_CODESOURCERYW=y : CodeSourcery under Windows
+ CONFIG_LPC31XX_CODESOURCERYL=y : CodeSourcery under Linux
+ CONFIG_LPC31XX_DEVKITARM=y : devkitARM under Windows
+ CONFIG_LPC31XX_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
+
+ If you are not using CONFIG_LPC31XX_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.
+
+ 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/lpc31xx,
+ arch/arm/src/common, arch/arm/src/arm, 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/lpc31xx/lpc31_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 ea3152/<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/arm926t-defconfig-4.2.4 .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.
+
+Boot Sequence
+^^^^^^^^^^^^^
+ LPC313x has on chip bootrom which loads properly formatted images from multiple
+ sources into SRAM. These sources include including SPI Flash, NOR Flash, UART,
+ USB, SD Card, and NAND Flash.
+
+ In all configurations, NuttX is loaded directly into ISRAM. NuttX is linked
+ to execute from ISRAM, regardless of the boot source.
+
+Image Format
+^^^^^^^^^^^^
+
+ In order to use the bootrom bootloader, a special header must be added to the
+ beginning of the binary image that includes information about the binary (things
+ like the entry point, the size, and CRC's to verify the image.
+
+ NXP provides a Windows program to append such a header to the binary image.
+ However, (1) that program won't run under Linux, and (2) when I try it under
+ WinXP, Symantec immediately claims that the program is misbehaving and deletes
+ it!
+
+ To work around both of these issues, I have created a small program under
+ configs/ea3152/tools to add the header. This program can be built under
+ either Linux or Cygwin (and probably other tool environments as well). That
+ tool can be built as follows:
+
+ - cd configs/ea3152/tools
+ - make
+
+ Then, to build the NuttX binary ready to load with the bootloader, just
+ following these steps:
+
+ - cd tools/ # Configure Nuttx
+ - ./configure.sh ea3152/ostest # (using the ostest configuration for this example)
+ - cd .. # Set up environment
+ - . ./setenv.sh # (see notes below)
+ - make # Make NuttX. This will produce nuttx.bin
+ - mklpc.sh # Make the bootloader binary (nuttx.lpc)
+
+ NOTES:
+
+ 1. setenv.sh just sets up pathes to the toolchain and also to
+ configs/ea3152/tools where mklpc.sh resides. Use of setenv.sh is optional.
+ If you don't use setenv.sh, then just set your PATH variable appropriately or
+ use the full path to mklpc.sh in the final step.
+ 2. You can instruct Symantec to ignore the errors and it will stop quarantining
+ the NXP program.
+ 3. The CRC32 logic in configs/ea3152/tools doesn't seem to work. As a result,
+ the CRC is currently disabled in the header:
+
+ RCS file: /cvsroot/nuttx/nuttx/configs/ea3152/tools/lpchdr.c,v
+ retrieving revision 1.2
+ diff -r1.2 lpchdr.c
+ 264c264
+ < g_hdr.imageType = 0x0000000b;
+ ---
+ > g_hdr.imageType = 0x0000000a;
+
+Image Download to ISRAM
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Assuming that you already have the FTDI driver installed*, then here is the
+are the steps that I use for loading new code into the EA3152:
+
+- Create the bootloader binary, nuttx.lpc, as described above.
+- Connected the EA3152 using the FTDI USB port (not the lpc3152 USB port)
+ This will power up the EA3152 and start the bootloader.
+- Start a terminal emulator (such as TeraTerm) at 115200 8NI.
+- Reset the EA3152 and you should see:
+ LPC31xx READY FOR PLAIN IMAGE>
+- Send the nuttx.lpc file and you should see:
+ Download finished
+
+That will load the NuttX binary into ISRAM and attempt to execute it.
+
+*See the LPC313x documentation if you do not have the FTDI driver installed.
+
+Using OpenOCD and GDB
+^^^^^^^^^^^^^^^^^^^^^
+
+ I have been using the Olimex ARM-USB-OCD JTAG debugger with the EA3152
+ (http://www.olimex.com). The OpenOCD configuration file is here:
+ tools/armusbocb.cfg. There is also a script on the tools directory that
+ I used to start the OpenOCD daemon on my system called oocd.sh. That
+ script would probably require some modifications to work in another
+ environment:
+
+ - possibly the value of OPENOCD_PATH
+ - If you are working under Linux you will need to change any
+ occurances of `cygpath -w blablabla` to just blablabla
+
+ Then you should be able to start the OpenOCD daemon like:
+
+ configs/ea3152/tools/oocd.sh $PWD
+
+ Where it is assumed that you are executing oocd.sh from the top level
+ directory where NuttX is installed.
+
+ Once the OpenOCD daemon has been started, you can connect to it via
+ GDB using the following GDB command:
+
+ arm-elf-gdb
+ (gdb) target remote localhost:3333
+
+ And you can load the NuttX ELF file:
+
+ (gdb) symbol-file nuttx
+ (gdb) load nuttx
+
+ARM/EA3152-specific 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_ARM926EJS=y
+
+ CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+ CONFIG_ARCH_CHIP=lpc313x
+
+ CONFIG_ARCH_CHIP_name - For use in C code
+
+ CONFIG_ARCH_CHIP_LPC3152
+
+ CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+ hence, the board that supports the particular chip or SoC.
+
+ CONFIG_ARCH_BOARD=ea3152
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_EA3152
+
+ 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 - For most ARM9 architectures, this describes the
+ size of installed DRAM. For the LPC313X, it is used only to
+ deterimine how to map the executable regions. It is SDRAM size
+ only if you are executing out of the external SDRAM; or it could
+ be NOR FLASH size, external SRAM size, or internal SRAM size.
+
+ CONFIG_DRAM_START - The start address of installed DRAM (physical)
+
+ CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
+
+ CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+ have LEDs
+
+ CONFIG_ARCH_IRQPRIO - The LPC313x supports interrupt prioritization
+
+ 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

+ 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.
+ CONFIG_ARCH_DMA - Support DMA initialization
+ CONFIG_ARCH_LOWVECTORS - define if vectors reside at address 0x0000:00000

+# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
+# CONFIG_BOARD_LOOPSPERMSEC - for delay loops
+# CONFIG_DRAM_SIZE - For most ARM9 architectures, this describes the
+# size of installed DRAM. For the LPC31XX, it is used only to
+# deterimine how to map the executable regions. It is SDRAM size
+# only if you are executing out of the external SDRAM; or it could

+# CONFIG_DRAM_START - The start address of DRAM (physical)
+# CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
+# CONFIG_ARCH_IRQPRIO - The LPC31xx supports interrupt prioritization
+# 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_BOOTLOADER - Set if you are using a bootloader.

+# from interrupt handlers. If the worker thread is disabled,
+# then that clean will be performed by the IDLE thread instead
+# (which runs at the lowest of priority and may not be appropriate
+# if memory reclamation is of high priority). If CONFIG_SCHED_WORKQUEUE
+# is enabled, then the following options can also be used:
+# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker

+ * Name: up_fillpage()
+ *
+ * Description:
+ * After a page is allocated and mapped by up_allocpage(), the actual
+ * filling of the page with data from the non-volatile, must be performed
+ * by a separate call to the architecture-specific function, up_fillpage().
+ * This function is non-blocking, it will start an asynchronous page fill.
+ * The common paging logic will provide a callback function, pg_callback,
+ * that will be called when the page fill is finished (or an error occurs).
+ * This callback is assumed to occur from an interrupt level when the
+ * device driver completes the fill operation.
+ *
+ * NOTE 1: Allocating and filling a page is a two step process. up_allocpage()
+ * allocates the page, and up_fillpage() fills it with data from some non-
+ * volatile storage device. This distinction is made because up_allocpage()
+ * can probably be implemented in board-independent logic whereas up_fillpage()
+ * probably must be implemented as board-specific logic.
+ *
+ * NOTE 2: The initial mapping of vpage will be read-able, write-able,
+ * but non-cacheable. No special actions will be required of
+ * up_fillpage() in order to write into this allocated page. If the
+ * virtual address maps to a text region, however, this function should
+ * remap the region so that is is read/execute only. It should be made
+ * cache-able in any case.
+
+ * Input Parameters:
+ * tcb - A reference to the task control block of the task that needs to
+ * have a page fill. Architecture-specific logic can retrieve page
+ * fault information from the architecture-specific context
+ * information in this TCB to perform the fill.
+ * pg_callbck - The function to be called when the page fill is complete.
+ *
+ * Returned Value:
+ * This function will return zero (OK) if the page fill was successfully
+ * started (the result of the page fill is passed to the callback function
+ * as the result argument). A negated errno value may be returned if an
+ * error occurs. All errors, however, are fatal.
+ *
+ * NOTE: -EBUSY has a special meaning. It is used internally to mean that
+ * the callback function has not executed. Therefore, -EBUSY should
+ * never be provided in the result argument of pg_callback.
+ *
+ * Assumptions:
+ * - This function is called from the normal tasking context (but
+ * interrupts siabled). The implementation must take whatever actions
+ * are necessary to assure that the operation is safe within this context.
+ * - Upon return, the caller will sleep waiting for the page fill callback
+ * to occur. The callback function will perform the wakeup.

+ * Micron Initialization Sequence from their data sheet for the Micron
+ * MT48LC32M16A2 32M x 16 SDRAM chip:
+ *
+ * "SDRAMs must be powered up and initialized in a predefined manner.
+ * Operational procedures other than those specified may result in
+ * undefined operation. Once power is applied to VDD and VDDQ
+ * (simultaneously) and the clock is stable (stable clock is defined as
+ * a signal cycling within timing constraints specified for the clock
+ * pin), the SDRAM requires a 100�s delay prior to issuing any command
+ * other than a COMMAND INHIBIT or NOP.
+ *
+ * "Starting at some point during this 100�s period and continuing at least
+ * through the end of this period, COMMAND INHIBIT or NOP commands should
+ * be applied. Once the 100�s delay has been satisfied with at least one
+ * COMMAND INHIBIT or NOP command having been applied, a PRECHARGE command
+ * should be applied. All banks must then be precharged, thereby placing
+ * the device in the all banks idle state.
+ *
+ * "Once in the idle state, two AUTO REFRESH cycles must be performed. After
+ * the AUTO REFRESH cycles are complete, the SDRAM is ready for mode
+ * register programming.
+ *
+ * "Because the mode register will power up in an unknown state, it should
+ * be loaded prior to applying any operational command."
+ *
+ * The JEDEC recommendation for initializing SDRAM is:
+ *
+ * APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ * Wait 200uS
+ * PRECHARGE all
+ * 8 AUTO REFRESH COMMANDS
+ * LOAD MODE REGISTER
+ * SDRAM is ready for operation
+ *
+ * The Micron SDRAM parts will work fine with the JEDEC sequence, but also
+ * allow for a quicker init sequence of:
+ *
+ * APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ * Wait at least 100uS (during which time start applying and
+ * continue applying NOP or COMMAND INHIBIT)
+ * PRECHARGE all

+ *
+ * Note that we take it "backwards" and put the highest-order term in the lowest-order bit.
+ * The X^32 term is "implied"; the LSB is the X^31 term, etc. The X^0 term (usually shown
+ * as "+1") results in the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which is what we're using
+ * (we're merely optimizing it by doing eight-bit chunks at a time) shifts bits into the
+ * lowest-order term. In our implementation, that means shifting towards the right. Why
+ * do we do it this way? Because the calculated CRC must be transmitted in order from
+ * highest-order term to lowest-order term. UARTs transmit characters in order from LSB
+ * to MSB. By storing the CRC this way we hand it to the UART in the order low-byte to
+ * high-byte; the UART sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit shuffling on our
+ * part. Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries. Notes
+ *
+ * - The table can be generated at runtime if desired; code to do so is shown later. It
+ * might not be obvious, but the feedback terms simply represent the results of eight
+ * shift/xor operations for all combinations of data and CRC register values
+ *
+ * - The values must be right-shifted by eight bits by the updcrc logic; the shift must
+ * be u_(bring in zeroes). On some hardware you could probably optimize the shift in
+ * assembler by using byte-swap instructions polynomial $edb88320
