+0.3.15 2008-09-20 Gregory Nutt <spudmonkey@racsa.co.cr>
+	* Added support for ROMFS filesystem.
+	* Added a simple test the ROMFS filesystem (examples/romfs)
+	* NSH: Use ROMFS to provide an option for a start-up script at /etc/init.d/rcS
+	* Add definition of BIOC_XIPBASE ioctl and implement in RAM disk block driver.
+	  This is a low level requirement for eXecute In Place (XIP) support.
+	* Add a FIOC_MMAP to perform memory mapping of a file and implemented the
+	  ioctl command in the ROMFS filesystem.  This is a requirement for eXecute
+	  In Place (XIP) support.
+	* Add mmap() API with restricted capability (only for XIP support)
+	* Extend ROMFS test at /examples/romfs to verify mmap() and XIP support.
+	* Add support for Intel Hex format output using objcopy
+	* Completed the basic port of the NXP LPC2148 on the mcu123.com board.
+	  The basic port includes successful booting, timer interrupts, serial console,
+	  succesfully passing the examples/ostest, and a NuttShell (NSH) configuration.
+	* ARM architectures now support drivers/lowconsole.c

+0.3.16 2008-10-10 Gregory Nutt <spudmonkey@racsa.co.cr>
+	* Added header files defining a common USB device controller architecture
+	* Added USB device side driver for the LPC214x
+	* Correct the frequency of system timer interrupts in the NXP LPC214x port
+	  (off by 20x in nuttx-0.3.15)
+	* Add an option to set aside a separate stack for interrupt handling (ARM only).
+	  This is useful when memory is constrained, there are multiple tasks, and
+	  the interrupt stack requirement is high (as when USB is enabled).
+	* Added USB serial class device side driver (emulates Prolific PL2303
+	  serial-to-USB adaptor)
+	* Add LPC214x USB serial configuration; Add examples/usbserial test
+	* Added USB device side driver for the DM320 (untested at initial release)
+	* Fixed an error in a previous (post 0.3.15) check-in that broke the LPC214x
+	  system timer.
+	* Fixed serial driver bugs related to (1) open counts and (2) recognizing
+	  O_NONBLOCK on read.
+	* Fixed an error in read(); it was not setting the errno on errors returned
+	  from the driver.
+
+0.3.17 2008-10-28 Gregory Nutt <spudmonkey@racsa.co.cr>
+	* Incorporate patch "[2164503] nuttx-0.3.16 does not build for ARM with USB disabled"
+	* Reduced the amount of memory reserved for USB serial control requests.  It
+	  was unnecessarily large.
+	* Added LPC214x SPI1 driver to interface with MMC on mcu123.com board.
+	* Added a simple SPI-based MMC/SD block driver
+	* NSH: Add LPC214x-specific support to NSH; NSH now mounts any SD cards in the slot.
+	* FAT: Fix access to unaligned 32-bit values in partion table (start sector & size)
+	* Fixed a problem with a un-initialized variable in the USB serial driver.
+	* Added USB storage NXP LPC214x configuration
+	* Added a test for USB storage under examples/usbstorage
+	* Fixed a bug in the LPC214x USB driver: It was not properly clearing a HALTed
+	  endpoints (other than EP) on receipt of CLEAR FEATURES request.
+	* Added USB storage class device side driver (BBB)
+	* Fixed a bug in the LPC214x USB driver: It was not properly handling request buffers
+	  larger then the endpoint's max packet (DM320 driver also fixed, untested)
+	* Added logic to the USB device interface:  A bit is needed to force the driver to
+	  to terminate an IN transfer with a short packet (zero-length if necessary).
+	* Fix an error in the NXP LPC214x USB device driver that was causing corruption of
+	  the request queue (M320 driver also fixed, untested)
+	* Correct another error in the NXP LPC214x USB device driver that caused read failures
+	  when the request buffer size was larger than maxpacket.
+	* Numerous corrections/extensions to the USB tracing logic included in 0.3.16 (but
+	  not integrated until 0.3.17)
+	* Fixed another bug in the NXP LPC214x USB device driver:  After a stalled endpoint
+	  is resumed (view CLEAR FEATURE), we must restart the IN (outgoing) queue.

+<p>
+  <b>NSH Start-Up Script</b>.
+  NSH supports options to provide a start up script for NSH.  In general
+  this capability is enabled with <code>CONFIG_EXAMPLES_NSH_ROMFSETC</code>, but has
+  several other related configuration options as described with the
+  <a href="#nshconfiguration">NSH-specific configuration settings</a>.
+  This capability also depends on:
+  <ul>
+    <li><code>CONFIG_DISABLE_MOUNTPOINT</code> not set
+    <li><code>CONFIG_NFILE_DESCRIPTORS</code> &lt; 4
+    <li><code>CONFIG_FS_ROMFS</code> enabled
+  </ul>
+</p>
+
+<p>
+  <b>Default Start-Up Behavior</b>.
+  The implementation that is provided is intended to provide great flexibility
+  for the use of Start-Up files.  This paragraph will discuss the general
+  behavior when all of the configuration options are set to the default
+  values.
+</p>
+<p>
+  In this default case, enabling <code>CONFIG_EXAMPLES_NSH_ROMFSETC</code> will cause
+  NSH to behave as follows at NSH startup time:
+  <ul>
+    <li>
+      NSH will create a read-only RAM disk (a ROM disk), containing a tiny
+      ROMFS filesystem containing the following:
+<ul><pre>
+`--init.d/
+     `-- rcS
+</pre></ul>
+      Where rcS is the NSH start-up script.
+    </li>
+    <li>
+      NSH will then mount the ROMFS filesystem at <code>/etc</code>, resulting in:
+<ul><pre>
+|--dev/
+|   `-- ram0
+`--etc/
+    `--init.d/
+        `-- rcS
+</pre></ul>
+    </li>
+    <li>
+      By default, the contents of rcS script are:
+<ul><pre>
+# Create a RAMDISK and mount it at XXXRDMOUNTPOUNTXXX
+
+mkrd -m 1 -s 512 1024
+mkfatfs /dev/ram1
+mount -t vfat /dev/ram1 /tmp
+</pre></ul>
+    </li>
+    <li>
+      NSH will execute the script at <code>/etc/init.d/rcS</code> at start-up (before the
+      first NSH prompt.  After execution of the script, the root FS will look
+      like:
+<ul><pre>
+|--dev/
+|   |-- ram0
+|   `-- ram1
+|--etc/
+|   `--init.d/
+|       `-- rcS
+`--tmp/
+</pre></ul>
+    </li>
+  </ul>
+</p>
+<p>
+  <b>Modifying the ROMFS Image</b>.
+  The contents of the <code>/etc</code> directory are retained in the file
+  <code>examples/nsh/nsh_romfsimg.h</code>.  In order to modify the start-up
+  behavior, there are three things to study:
+  <ol>
+    <li>
+      <b>Configuration Options.</b>
+      The additional <code>CONFIG_EXAMPLES_NSH_ROMFSETC</code> configuration options
+      discussed with the other <a href="#nshconfiguration">NSH-specific configuration settings</a>.
+    </li>
+    <li>
+      <p>
+        <b><code>mkromfsimg.sh</code> Script</b>.
+        The script <code>examples/nsh/mkromfsimg.sh</code> creates <code>nsh_romfsimg.h</code>.
+        It is not automatically executed.  If you want to change the
+        configuration settings associated with creating and mounting
+        the <code>/tmp</code> directory, then it will be necessary to re-generate
+        this header file using the <code>mkromfsimg.sh</code> script.
+      </p>
+      <p>
+        The behavior of this script depends upon three things:
+        <ul>
+          <li>The configuration settings then installed configuration.
+          <li>The <code>genromfs<code> tool (available from <a href="http://romfs.sourceforge.net">http://romfs.sourceforge.net</a>).
+          <li>The file <code>examples/nsh/rcS.template</code>.
+        </ul>
+      </p>
+    </li>
+    <li>
+      <b><code>rcS.template</code></b>.
+      The file <code>examples/nsh/rcS.template</code> contains the general form
+      of the <code>rcS</code> file; configurated values are plugged into this
+      template file to produce the final <code>rcS</code> file.
+    </li>
+  </ol>
+</p>
+<p>
+  All of the startup-behavior is contained in <code>rcS.template</code>.  The
+  role of <code>mkromfsimg.sh</code> is to (1) apply the specific configuration
+  settings to <code>rcS.template</code> to create the final <code>rcS</code>, and (2) to
+  generate the header file <code>nsh_romfsimg.h</code> containg the ROMFS
+  file system image.

+  This is an early alpha release of these drivers.

+  Several important bugs were also fixed in the FAT file system, USB serial driver and
+  NXP LPC214x USB controller driver (see the current <a href="#currentrelease">ChangeLog</a> for details).

 <p>
+  These changes were verified only on the mcu123.com NXP LPC2148 board using a Linux development environment.

-	* FAT FS now uses position variable in struct file.  This simplifies operations
-	  like ftell().
-	* fseek() needs to discard bytes buffered by ungetc().
-	* Corrected ftell() return value.
-	* Added fsetpos() and fgetpos().
-	* NSH: Now supports 'test' and '[' commands
-	* Correct error in send() timeout logic.
-	* Correct error in multi-threaded socket handling in send() and sendto().
-	  Outgoing data could overwrite incoming data.
-	* Add support to uIP for application access to ICMP protocol stacks; Add
-	  ping request logic.
-	* NSH: Add ping command
-	* Correct IP checksum calculation in ICMP and UDP message send logic.
-	* NSH: Created an HTML document and a more detailed README file describing NSH.
-	* Added basic TFTP client logic (netutils/tftpc).  Untested as of initial check-in.
-	* NSH: Add get and put commands to support TFTP get and put operations.
-	* NSH: Added a mkrd command that will create a RAMDISK that can be formatted
-	  and mounted.
-	* Corrected a critical bug that prevent recvfrom from receiving packets from
-	  any remote UDP port.
-	* NSH: Add hexadecimal dump command (xd)
-	* Fixed several critical bugs with regard to fat reading and writing and FAT12

+nutt-0.3.15
+^^^^^^^^^^^
+
+This is the 27th release of NuttX.  This release includes some new features:
+
+  * Adds support for the ROMFS filesystem
+  * ROMFS supports mmap() to provide eXecute In Place (XIP) capability
+  * NuttShell (NSH) can be configured to use ROMFS to provide a tiny read-only
+    filesystem with a startup script in /etc.
+  * Completed the basic port of the NXP LPC2148 on the mcu123.com board.
+    The basic port includes successful booting, timer interrupts, serial console,
+    succesfully passing the examples/ostest, and a NuttShell (NSH) configuration.
+
+These changes were verified only on the mcu123.com NXP LPC2148 board.  Please report

+
+nutt-0.3.16
+^^^^^^^^^^^
+
+This is the 28th release of NuttX.  This release includes the first support for
+USB in NuttX.  A set of USB APIs were added to support USB device controller
+drivers and bindings to USB device class drivers.  The form of the interface
+was inspired by the Linux Gadget APIs.
+
+At present USB device controller drivers are included for:
+
+  * The NXP LPC214x.  This driver has been verified and is an early alpha
+    stage in quality.
+  * TI DM320.  Coding for this driver is complete but it is completely untested
+    as of this release.
+
+A controller-independent class driver is also included for:
+
+  * USB serial class device driver (emulates the Prolific PL2303 serial-to-USB
+    adaptor).  This drver has only been verified with the Linux host PL2303
+    driver.
+
+Other new features include:
+
+  * Add an option to set aside a separate stack for interrupt handling (ARM only).
+    This is useful when memory is constrained, there are multiple tasks, and
+    the interrupt stack requirement is high (as when USB is enabled).
+
+A few bugs were also fixed:
+
+  * Fixed the frequency of system timer interrupts in the NXP LPC214x port
+    (off by 20x in nuttx-0.3.15)
+  * Fixed serial driver bugs related to (1) open counts and (2) recognizing
+    O_NONBLOCK on read.
+  * Fixed an error in read(); it was not setting the errno on errors returned
+    from the driver.
+
+These changes were verified only on the mcu123.com NXP LPC2148 board using with
+a Linux host.  Please report any errors to me.
+
+This tarball contains a complete CVS snapshot from Octobor 10, 2008.

+    based MMC/SD card on the NXP LPC214x.
+
+This is an early alpha release of these drivers.  At present they only work with
+debug features enabled so there are probably some race conditions that occur only
+with debug features disabled (anyone out there with a USB analyzer?  I would love
+to know what is happening).
+
+At present USB device controller drivers are included for:
+
+Several important bugs were also fixed in the FAT file system, USB serial driver and
+NXP LPC214x USB controller driver (see the ChangeLog for details).
+
+These changes were verified only on the mcu123.com NXP LPC2148 board using a Linux
+development environment.  USB testing was performed using both a Linux host and a WinXP
+host.  Please report any errors to me.
+
+This tarball contains a complete CVS snapshot from Octobor 28, 2008.
