+        <li>
+          The X target does not build under recent Cygwin configurations.

+        <li>
+          The sim target itself is broken under 64-bit Linux.
+          This is because the sim target is based upon some assembly language setjmp/longjmp logic that only works on 32-bit systems.

+INSTALLATION
+^^^^^^^^^^^^
+
+Download and Unpack:
+
+  Download and unpack the NuttX tarball.  If you are reading this, then
+  you have probably already done that.  After unpacking, you will end
+  up with a directory called nuttx-version (where version is the NuttX
+  version number). You might want to rename that directory nuttx to
+  match the various instructions in the documentation and some scripts
+  in the source tree.
+
+  That nuttx build directory should reside in a path that contains no
+  spaces in the higher level directory names.  For example, under
+  Cygwin, your home directory might be formed from your first and last
+  names like: "/home/First Last". That will cause strange errors when
+  the make system tries to build.
+
+  [Actually, that problem is probably not to difficult to fix.  Some
+   Makefiles probably just need some pathes within double quotes]
+
+A Note about Header Files:
+
+  Some toolchains are built with header files extracted from a C-library
+  distribution (such as newlib).  For those toolchains, NuttX must be
+  compiled without using the standard header files that are distributed
+  with your toolchain.  This prevents including conflicting, incompatible
+  header files (such as stdio.h).
+
+  Certain header files, such as setjmp.h and varargs.h, may still be
+  needed from your toolchain, however.  If that is the case, one solution
+  is to copy those header file from your toolchain into the NuttX include
+  directory.
+
+  Also, if you prefer to use the stdint.h and stdbool.h header files from
+  your toolchain, those could be copied into the include/ directory too.
+  Using most other header files from your toolchain would probably cause
+  errors.

+^^^^^^^^^^
+
+This is the 46th release of NuttX.  The release extends the support for the STMicro
+STM32 microcontroller.  Minimal support for the STM3210E-EVAL development board based
+around the STM32F103ZET6 MCU was released in NuttX-0.4.12 and extended in Nuttx-0.4.13
+to include initial USB support.  This completes the STM32F103ZET6 and adds:
+
+New Generic RTOS Features:
+
+	* Added generic support that can be included in any block driver to provide
+	  read-ahead buffering and write buffering for improved driver performance.
+	* Added a generic worker thread that can used to defer processing from an
+	  interrupt to a task.
+	* Defined a generic SD/SDIO interface can can be bound to a MMC/SD or SDIO
+	  driver to orovide SDIO support.
+	* Implemented a an SDIO-based MMC/SD driver using this new SDIO interface
+
+New STM32 Features:
+
+	* Add support to configure an STM32 input GPIO to generate an EXTI interrupt.
+	* Added support for buttons on the STM3210E-EVAL board.
+	* Implemented an STM32 version of the common the SDIO interface.
+	* Added a configuration to exercise the STM32 with the USB mass storage
+	  device class example.
+
+This release also corrects some important bugs in the early STM32 release:
+
+	* Correct error handling in the mount() logic.
+	* Fixed several STM32 DMA-related issues. Integrated and debugged STM32 DMA
+	  functionality that was added in 0.4.12.
+	* Fixed several bugs in the STM32 USB device-side driver.
+
+NOTE:  This version, 4.14, is equivalent to what would have been called 0.4.14
+to follow 0.4.13.  The zero has been eliminated from the front of the version
+number to avoid confusion about the state of development:  Some have interpreted
+the leading zero to mean that the code is in some way unstable.  That was not
+the intent.  Beginning in January 2010, I will switch to the 2010.nn versioning
+as many others have done to avoid such confusion.

+
+nuttx-5.0
+^^^^^^^^^
+
+This is 47th release of NuttX and the successor to nuttx-4.14.  This
+major revision number has been incremented to indicate that an
+incompatibility with previous nuttx releases has been introduced.  This
+version adopts standard fixed width integer names as specified by the
+ANSII C99 standard.  The core logic of NuttX is older than that
+standard and did not conform to it.
+
+If you have applications running on nuttx-4.14, those applications
+should continue to build and execute without problem on nuttx-5.0.
+However, if you have device drivers or other OS-internal logic, you
+will probably have to make some minor changes to your code to use
+this version.  Below is a summary of those changes:
+
+o If you include sys/types.h to get the non-standard, fixed width
+  integer types (uint32, uint16, ubyte, etc.), that is no longer
+  necessary.
+o Instead, you will need to include stdint.h where the new fixed width
+  integer types are defined (uint32_t, uint16_t, uint8_t, etc.).
+o You will have to change all occurrences of the following types:
+
+  uint32 -> uint32_t
+  uint16 -> uint16_t
+  ubyte  -> uint8_t
+  uint8  -> uint8_t
+  sint32 -> int32_t
+  sint16 -> int16_t
+  sint8  -> int8_t
+
+o In addition, the non-standard type 'boolean' must replaced with the
+  standard type 'bool'.  The type definition for 'bool' is in stdbool.h
+
+This change in typing caused small changes to many, many files.  It was
+verified that all configurations in the release still build correctly
+(other than the SDCC-based configurations).  Regression testing was
+performed on a few configurations, but it is possible that minor build
+issues still exist (if you encounter any, please let me know and I will
+help you to fix them).
+
+In the course of the regression testing, several important bugs unrelated
+to the type changes were found and corrected.
+
+o Fixed an important error in the RX FIFO handling logic of the LM3S6918
+  Ethernet driver.
+o Corrected the handling of TCP sequence numbers in the TCP stack.
+o And other less important bugs as detailed in the ChangeLog.
+
+The primary focus of this release was standards compatibility, but a
+few new features were added including a (1) Flash Translation Layer (FTL)
+that will support filesystems on a FLASH device and (2) partial ports
+for the STM32F107VC and HCS12 C9S12NE64 MCUs.  Those ports are very
+incomplete as of this writing.

+
+nuttx-5.1
+^^^^^^^^^
+
+This is the 48th release of NuttX.  This release adds support for two new
+MCU architectures in various states of development:
+
+o AT91SAM3U (http://www.atmel.com/products/at91/sam3landing.asp?family_id=605)
+
+  This release adds support for the SAM3U-EK development board with the
+  AT91SAM3U4E MCU (http://www.atmel.com/dyn/products/product_card_mcu.asp?part_id=4562).
+  As with most NuttX architecutre releases, the release will be rolled out in
+  two parts:  A basic port and an extended port.
+
+  NuttX-5.1 includes the basic port for the SAM3U-EK board.  This release
+  passes the NuttX OS test and is proven to have a valid OS implementation.
+  It supports the basic boot-up, serial console and timer interrupts.  A
+  configuration to support the NuttShell is also included.
+
+  The extended port will also include support for SDIO-based SD cards and
+  USB device (and possible LCD support).  These extensions may or may not
+  happen by the Nuttx 5.2 release as my plate is kind of full now.
+
+o LPC3131 (http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/)
+
+  This release also adds the complete implementation of the basic port for
+  the NXP LPC3131 MCU on the Embedded Artists EA3131 board
+  (http://www.embeddedartists.com/products/kits/lpc3131_kit.php).  That port,
+  unfortunately has stalled due to tools issues.  Those tool issues have
+  been resolved and I am confident that the verified basic port will be
+  available in NuttX-5.2.
+
+  The extended release will follow and should include SDIO-based SD card
+  support and device USB.
+
+A few additional features and bugfixes of a minor nature were also incorporated
+as detailed in the ChangeLog.
+
+nuttx-5.2
+^^^^^^^^^
+
+This is the 49th release of NuttX.  This release completes the verification of
+the basic port for the NXP LPC3131 MCU on the Embedded Artists EA3131 board
+(http://www.embeddedartists.com/products/kits/lpc3131_kit.php).  This basic
+port includes basic boot-up, serial console, and timer interrupts.  This port
+has been verified on the using the NuttX OS test and includes a working
+implementation of the NuttShell (NSH).
+
+An extended release will follow and should include SDIO-based SD card
+support and device USB.
+
+nuttx-5.3
+^^^^^^^^^
+
+This is the 50th release of NuttX.  This release suport for one new achitecture:
+
+  * A basic port for the NXP LPC2378 MCU on the Olimex-LPC2378 development board
+    was contributed by Rommel Marcelo.
+
+And extensions to two existing architures:
+
+  * David Hewson contributed a dual-speed (full/high) USB device-side driver
+    for the NXP LPC3131 on the Embedded Artists EA3131 development board.
+  * A DMA driver and a high speed MCI driver for the Atmel AT91SAM3U are
+    included (but not fully tested in this release).
+
+Two important bugfix was also included:
+
+  * An important fix to the USB mass storage driver was contributed by
+    David Hewson.
+  * A serious error in the AT91SAM3U PIO handling was fixed.
+
+nuttx-5.4
+^^^^^^^^^
+
+This is the 51st release of NuttX.  This release includes one new, important
+extension to th NX graphics system (See http://www.nuttx.org/NXGraphicsSubsystem.html).
+
+NX was develop a couple years back on hardware that supported only framebuffer
+devices, that is, video hardware with video memory directly converts the memroy
+content to video.  However, most MCUs that NuttX focuses on do not support such
+video memory; rather, that typically only support LCDs via parallel or serial
+interfaces.
+
+This release of NuttX extends NX so that now renders directly to the LCD device
+via its serial or parallel interface.  No in-memory copy of the screen memory
+need be maintained so this solution should also work in MCUs with very limited
+SRAM.
+
+This initial release of this feature includes the verified NX extensions plus
+a driver for the HX8347, 16-bit parallel LCD.  This LCD supports 16-bit RGB
+(5:6:5).
+
+nuttx-5.5
+^^^^^^^^^
+
+This is the 52nd release of NuttX.  This release includes one new port, some
+new drivers and some important bugfixes:
+
+  * NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation Kit.
+    At present, that port includes an OS test configuration and a NuttShell
+    (NSH) configuration with telnet support.
+
+    MMC/SD and Networking support are provided but not thoroughly verified
+    in this release: Current development efforts are focused on porting the
+    NuttX window system (NX) to work with the Evaluation Kits OLED display.
+
+  * A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet chip is
+    available in the source tree (but has not yet been fully verified because
+    I haven't properly connected it to hardware yet).
+
+  * The Olimex STR-P711 NuttX port was extended to support the ENC28J60 and
+    some new networking configurations were added.  The ENC28J60 has not
+    been tested on the STR-P711, however, because of hardware issues (I don't
+    think the USB powered board provides enough power for the ENC28J60 and
+    I don't have the right wall wart yet).
+
+    Along the way, external interrupt support (XTI) was added to the STMicro
+    STR-P711 port and some important bugs were fixed in the STR-P711 SPI
+    driver.
+
+  * Added (optional) floating point support for printf() (contributed by
+    Yolande Cates).
+
+  * Corrected an important UDP reference counting error.  It was not a serious
+    error, but it trigger an assertion was IS a serious error.
+
+nuttx-5.6
+^^^^^^^^^
+
+This is the 53rd release of NuttX.  This release includes one several new drivers
+for existing NuttX ports:
+
+  * This port adds support for the RiT displays P14201 4-bpp, greyscale OLED.
+    4-bpp greyscale support was integrated into the NX graphics sub-system and
+    verified using the TI/Luminary LP3S6965 Ethernet Evaluation Kit.
+
+  * The MP25Px driver was extended for the M24P1 FLASH part (see NOTE).
+
+  * An I2C driver and (basic) SPI driver were added for the NXP LPC313x port.
+    The I2C interface definition was extended to efficiently handle multiple I2C
+    transfers (See NOTE).
+
+    NOTE: Contributed by David Hewson.
+
+As well as a few, important USB-related bugfixes (See the ChangeLog for details).
+
+This release also includes the beginnings of a port for the NXP LPC1768 MCU.  However,
+it is too early for that port to be useful (stay tuned for a future announce of the
+availability of the LPC1768 port).
+
+nuttx-5.7
+^^^^^^^^^
+
+This is the 54th release of NuttX.  This release adds basic support for one new
+ARM Cortex-M3 architecture:
+
+  * Added support for NXP LPC1768 MCU as provided on the Nucleus 2G board from
+    2G Engineering (http://www.2g-eng.com).
+  * Some initial files for the LPC17xx family were released in NuttX 5.6, but the
+    first functional release for the NXP LPC1768/Nucleus2G occured with NuttX 5.7.
+  * That initial basic release included timer interrupts and a serial console and was
+    verified using the NuttX OS test.
+  * That release includes a verified NuttShell (NSH) configuration
+    (see the http://www.nuttx.org/NuttShell.html).
+  * Also included are unverified SPI and USB device drivers.
+
+Further efforts include: (1) development of a DMA support library, (2) SPI-based MMC/SD
+support, and (3) verification of the USB driver.  Watch for announcement of the completed
+LPC1768 port expected in NuttX-5.8.
