 	* Fixed another FAT bug in implementation of FAT lseek; this prohibit correct
 	  random access to large files.
 
-0.3.15 2008-xx-xx Gregory Nutt <spudmonkey@racsa.co.cr>
+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.
+
+0.3.18 2008-11-16 Gregory Nutt <spudmonkey@racsa.co.cr>
+	* Added port for the STMicro STR71x processor and configuration for the Olimex STR-P711
+	  board (STR71x testing is stalled because I have been unable to get OpenOCD to
+	  communicate with my JTAG wiggler on Linux).
+	* Fix race condition workaround delay in LPC214X SPI logic.  This was also the cause of the
+	  very bad MMC/SD performance.
+	* Began port of the Hitachi SH-1 using the SH-1/US7032EVB1 board
+	* Re-built all configurations that use SDCC and Zilog toolchains to make sure they still
+	  build (they didn't, but they do now).
+	* Fixed several erroneous "list empty" checks in the CAN driver.
+	* Hitachi SH-1 passes (reduced) examples/ostest; the examples/nsh test still fails.
+	  There are remaining instabilities that make the port un-usable.  The nature of these is
+	  not understood; the behavior is that certain SH-1 instructions stop working as advertised.
+	  This could be a silicon problem, some pipeline issue that is not handled properly by the
+	  gcc 3.4.5 toolchain (which has very limit SH-1 support to begin with), or perhaps with the
+	  CMON debugger.  At any rate, I have exhausted all of the energy that I am willing to put
+	  into this cool old processor for the time being.
+	* Renamed configuration item CONFIG_PROC_STACK_SIZE as CONFIG_IDLETHREAD_STACKSIZE:  It now
+	  only controls the size of the stack for the IDLE thread.  Added CONFIG_USERMAIN_STACKSIZE:
+	  This is the size of stack used with the user_start() thread is created.  The two stacks
+	  no longer have to be the same.
+	* Add a loop device that converts a file into a block device.
+	* Each NSH command can not be disabled through a configuration setting. All of these
+	 settings make the configuration of NSH potentially complex but also allow it to squeeze
+	  into very small memory footprints.
+	* Added a block to character (BCH) driver.  This is kind of the reverse of the loop
+	  device; it allows you access a block device like a character device.
+	* Added strcasecmp() and strncasecmp()
+	* NSH: Added the 'dd' command
+	* NSH: Added the 'losetup' command
+	* Fixed a FAT bug:  After recent changes, it would mount a (invalid) FAT file system
+	  even if the medium is not formatted!
+	* Corrected two important errors in FAT lseek implementation: (1) the sectors-per-cluster
+	  value was being reset to "1" and (2) important lseek logic was omitted when the seek
+	  position was zero.
+	* Fixed a bug in getopt().  It would fail if on certain combinations of terminal argument
+	  types.

-  The nuttx-0.3.14 release includes some important bug fixes as well as a few new features.
-  Critical bugs fixed include:
+  This release includes two partially completed ports, several new features, and a

   <ul>
-    <li>FAT FS:
-      <ul>
-        <li>Fixed several critical bugs with regard to fat reading and writing and FAT12

+    <li>The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board.</li>
   </ul>
 </p>
 <p>
-  New features were also added:
+  Progress on these ports is stalled (as detailed in the ChangeLog).
+</p>
+<p>
+  The new features focus primarily on management of block devices and extensions of
+  the NuttShell (NSH).  These new features include:
   <ul>
-    <li>Network:
-      <ul>
-        <li>Added support for application access to ICMP protocol stacks; Added
-          ping request logic (<code>net/uip</code>).
-        <li>Added basic TFTP client logic (<code>netutils/tftpc</code>).
-      </ul>
-    </li>
-    <li>NuttShell (NSH):
-      <ul>
-        <li>New commands: <code>test</code>, <code>[</code>, <code>ping</code>,
-        <code>mkrd,</code> <code>xd</code>, andTFTP <code>get</code> and <code>put</code> commands.
-        (See the new NuttShell User Guide for additional information).
-      </ul>
-    </li>
+    <li>A loop device that converts a file into a block device,</li>
+    <li>A block to character (BCH) driver that  allow access a block device as if it were character device, </li>
+    <li>Added strcasecmp() and strncasecmp() libc functions, and </li>
+    <li>Added the 'dd' and 'losetup' commands to NSH. These commands (along with mkfatfs and mount),
+        give good managment of filesystems on the target.</li>
   </ul>
 </p>
 <p>
-  As usual, any feedback about bugs or suggestions for improvement would be greatly appreciated.
+  Several bugs were fixed, the most important of which are:
+  <ul>
+    <li>Fixd a race condition workaround delay in LPC214X SPI logic.  This was also
+        the cause of some bad MMC/SD performance on that platform.</li>
+    <li>Fixed a recently introduced FAT file system problem: It would mount a (invalid)
+        FAT file system even if the medium is not formatted!</li>
+    <li>Corrected two iother important errors in the FAT lseek implementation:
+        (1) the sectors-per-cluster value was being reset to "1" and (2) important
+        lseek logic was omitted when the seek position was zero.</li>
+  </ul>
+</p>
+<p>
+  The FAT filesystem has had many bugs fixed in it and, I think, is now maturing
+  and becoming stable.
+</p>
+<p>
+  These changes were verified only on the mcu123.com NXP LPC2148 board, the Hitachi
+  SH1_LCEVB1 board, and the Linux simulator, all using a Linux development environment.
+  Please report any errors to me.

+	* Hitachi SH-1 passes (reduced) examples/ostest; the examples/nsh test still fails.
+	  There are remaining instabilities that make the port un-usable.  The nature of these is
+	  not understood; the behavior is that certain SH-1 instructions stop working as advertised.
+	  This could be a silicon problem, some pipeline issue that is not handled properly by the
+	  gcc 3.4.5 toolchain (which has very limit SH-1 support to begin with), or perhaps with the
+	  CMON debugger.  At any rate, I have exhausted all of the energy that I am willing to put
+	  into this cool old processor for the time being.
+	* Renamed configuration item CONFIG_PROC_STACK_SIZE as CONFIG_IDLETHREAD_STACKSIZE:  It now
+	  only controls the size of the stack for the IDLE thread.  Added CONFIG_USERMAIN_STACKSIZE:
+	  This is the size of stack used with the user_start() thread is created.  The two stacks
+	  no longer have to be the same.
+	* Add a loop device that converts a file into a block device.
+	* Each NSH command can not be disabled through a configuration setting. All of these
+	  settings make the configuration of NSH potentially complex but also allow it to squeeze
+	  into very small memory footprints.
+	* Added a block to character (BCH) driver.  This is kind of the reverse of the loop
+	  device; it allows you access a block device like a character device.
+	* NSH: Added the 'dd' command
+	* NSH: Added the 'losetup' command
+	* Fixed a FAT bug:  After recent changes, it would mount a (invalid) FAT file system
+	  even if the medium is not formatted!
+	* Corrected two important errors in FAT lseek implementation: (1) the sectors-per-cluster
+	  value was being reset to '1' and (2) important lseek logic was omitted when the seek
+	  position was zero.
+	* Fixed a bug in getopt().  It would fail if on certain combinations of terminal argument
+	  types.

+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.

+nuttx-0.3.17
+^^^^^^^^^^^^
+
+This is the 29th release of NuttX.  This release includes the additional support for
+USB in NuttX.  The following new features were added:
+
+  * Added support for SPI-based MMC/SD cards (with an SPI driver for the NXP LPC214x).
+  * Added USB storage class device side driver (BBB)
+  * Added an example that demonstrates the USB storage class by exporting the SPI
+    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).
+
+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.

+
+nuttx-0.3.18
+^^^^^^^^^^^^
+
+This is the 30th release of NuttX.  This release includes two partially completed
+ports, several new features, and a couple of important bug fixes.  The two partially
+completed ports are:
+
+	* The STMicro STR71x processor and configuration for the Olimex STR-P711
+	  board.
+	* The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board
+
+Progress on these ports is stalled (as detailed in the ChangeLog).
+
+The new features focus primarily on management of block devices and extensions of
+the NuttShell (NSH).  These include:
+
+	* A loop device that converts a file into a block device.
+	* A block to character (BCH) driver that  allow access a block device as
+	  if it were character device.
+	* Added strcasecmp() and strncasecmp() libc functions.
+	* Added the 'dd' and 'losetup' commands to NSH. These commands (along
+	  with mkfatfs and mount), give good managment of filesystems on the target.
+
+Several bugs were fixed, the most important of which are:
+
+	* Fixd a race condition workaround delay in LPC214X SPI logic.  This was also
+	  the cause of some bad MMC/SD performance on that platform.
+	* Fixed a recently introduced FAT file system problem: It would mount a (invalid)
+	  FAT file system even if the medium is not formatted!
+	* Corrected two iother important errors in the FAT lseek implementation:
+	  (1) the sectors-per-cluster value was being reset to "1" and (2) important
+	  lseek logic was omitted when the seek position was zero.
+
+The FAT filesystem has had many bugs fixed in it and, I think, is now maturing
+and becoming stable.
+
+These changes were verified only on the mcu123.com NXP LPC2148 board, the Hitachi
+SH1_LCEVB1 board, and the Linux simulator, all using a Linux development environment.
+Please report any errors to me.
