   These unreleased changes are also listed <a href="#pendingchanges">here</a>.
 </p>
 <p>
-  Changes in this release are summarized below:
+  This release includes a few new features and several important bug fixes.
+  The new features (some still incomplete) include:
 </p>
 <ul>
-  <li><b>FreeScale Kinetis Support</b>.
-    NuttX has been ported to run on the FreeScale Cortex-M4 &quot;Kinetis&quot; boards.
-    Two board ports are available for (1) the Kinetis KwikStik-K40 and
-    (2) the Kinetis TWR-K60N512 tower.
+  <li><b>Analog Support/ NXP LPC17xx</b>:
+    New DAC sub-system including ADC and DAC drivers for the LPC17xx.
+    Extensions to the ADS1255 driver. (Contributed by Li Zhuoyi (Lzyy))
   </li>
-  <li><b>RGMP 0.3</b>.
-    Support for RGMP 0.3.  This version of RGMP now runs on the OMAP4430 (arm)
-    pandaboard
+  <li><b>Power Management</b>: 
+    Added a new NuttX power management sub-system for controlling and coordinating reduced power states.
+    At present, only verified in a simulation environment.
   </li>
-  <li><b>LPC17xx CAN driver</b>.
-    LPC17xx CAN driver extended to support both CAN1 and CAN2 (submitted by
-    Li Zhuoy (Lzzy)).  A Semaphore overflow problem was also corrected in the
-    CAN driver (reported by Li Zhouy (Lzzy)).
+  <li><b>I2C Test Tool</b>:
+    A new application was added that can be used to verify and debug I2C interfaces from the NuttShell (NSH) command line.
   </li>
-  <li><b>Signal-related bugfixes</b>.
-    Fixed several critical bugs related to signal handling initialization and
-    for signals the wake up tasks that are waiting to send or receive message
-    queues.Both are important (submitted by hkwilton).
+  <li><b>NuttShell (NSH)</b>:
+    In addition to the I2C test tool, a <code>date</code> command is now supported (if <code>CONFIG_RTC</code> is defined) that can be used to read and set the RTC.
   </li>
-  <li><b>ADC Infrastructure</b>.
-    Added a new ADC driver infrastructure and TI ADS1255 driver both
-    developed and submitted by Li Zhouy (Lzzy)).
+  <li><b>NXP LPC17xx</b>:
+    I2C and DAC drivers for the NXP LPC17xx family submitted by Li Zhuoyi (Lzyy)
+  </li>
+  <li><b>Kinetis Cortex-M4</b>:
+    Added a SDHC driver for the Kinetis parts.
+    Complete debug of the Kinetis SDHC driver was not completed, however, do to some higher priority tasks that forced me to stop work.
+  </li>
+  <li><b>Other new drivers</b>:
+    Driver for I2C-based at24cxx EEPROM submitted by Li Zhuoyi (Lzyy);
+    Driver for the LM-75 temperature sensor. 
+    Support for the LM-75 temperature sensor integrated into the STMicro STM3210E-EVAL development board.
+  </li>
+  <li><b>NuttX Graphics (NX)</b>:
+    Added new NX interfaces for drawing circles,  both circle outlines and filled circles.
+  </li>
+  <li><b>FLASH</b>:
+    Added a function that accepts the path to a block driver and then erases the underlying FLASH memory
+  </li>
+  <li><b>Build System</b>:
+    The Make export logic now also tries to track down all architecture-specific header files and include these in the NuttX export bundle as well.
+    Various changes and modifications so that NuttX wil build on FreeBSD using the ASH shell (submitted by Kurt Lidl).
+  </li>
+</ul>
+<p>
+  Bugfixes, order roughly on decreasing criticality include:
+</p>
+<ul>
+  </li>
+  <li><b>STM32 I2C Driver</b>:
+    Add resets, timeout, and other fixes to work reliably with the I2C tool.
+    Corrected a major error introduced in NuttX 6.8.
+  </li>
+  <li><b>BCH Driver</b>.
+    Several important bugs (noted by Li Zhuoyi (Lzyy)) were fixed.
+  </li>
+  <li><b>C Library</b>:
+    Fixed errors in <code>gmtime()</code> and <code>gmtime_r()</code> that could lead to errors in date calculations.
+  </li>
+  <li><b>Timing</b>:
+    Correct an error in the <code>tv_nsec</code> calculation that happens only config <code>CONFIG_RTC</code> is enabled
+  </li>
+  <li><b>Build System</b>:

+nuttx-6.9 2011-09-11 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
 
-    * arch/arm/src/lpc17xx/chip.h:  Fix some chip memory configuration errors
-      for the LPC1764, LPC1756, and LPC1754 (submitted by Li Zhuoy (Lzzy))
-    * arch/arm/src/lpc17xx/lpc17_can.h:  Revised CAN driver submitted by
-       Li Zhuoy (Lzzy).  The driver now supports both CAN1 and CAN2.
-    * arch/arm/sim/up_lcd.c: Add a simulated LCD driver.
-    * configs/stm3210e-eval/nxlines:  Added a configuration to build
-      examples/nxlines.
-    * arch/graphics: Used apps/examples/nxlines to (finally) verify the NX
-      trapezoid drawing functions and (wide) line drawing functions.
-    * arch/rgmp and configs/rgmp.  Yu Qiang has ported RGMP to the OMAP4430 (arm)
-      pandaboard and release the new RGMP 0.3 version. The main changes are: (1)
-      Separate configs/rgmp/x86 and configs/rgmp/arm configuration directory, and
-      (2) Extract architecture dependent code in arch/rgmp/include and
-      arch/rgmp/src into corresponding x86/ and arm/ directories.
-    * arch/arm/src/kinetis, arch/arm/include/kinetis, configs/kwikstik-k40:
-      Add a directory structure to support the port to the Kinetis KwikStik-K40.
-      There is no real substance in the initial check-in; only the directory
-      structure and skeleton files (Code complete on 8/15/11).
-    * arch/arm/include/armv7-m, arch/arm/src/armv7-m, etc.: Rename all cortexm3
-      directories and files to armv7-m; Change name of of all CORTEXM3 constants
-      to ARMV7M.  This is a major namespace change needed to cleanly support the
-      ARM Cortex-M4 which is also in the ARMv7 M Series (specifically, ARMv7E-M).
-    * sched/sig_initialize.c, sig_received.c, and mq_waitirq.c.  Fixed several
-      critical bugs related to signal handling initialization and for signals
-      the wake up tasks that are waiting to send or receive message queues.  In
-      the first two files, errors would prevent proper allocation of signal-related
-      structures from interrupt handlers.  In the second, there was missing
-      &quot;clean-up&quot; logic after a signal occurred, leaving the message queue in
-      a bad state and resulting in PANICs.  All are important.  (submitted by
-      hkwilton).
-    * arch/arm/src/kinetis:  Added header files defining all Kinetis registers
-      and bit fields within all Kinetis registers.
-    * configs/twr-k60n512:  Add support for the Kinetis K60 Tower board
-      (TWR-K60N512).
-    * drivers/can.c:  Fixe a semaphore overflow problem in the CAN driver
-      (reported by Li Zhouy (Lzzy)).
-    * 8/18/2011: The basic port to the FreeScale Kinetics TWR-K60N512 board is
-      now functional.
-    * confgs/twr-k60n512: Add Kinetics TWR-K60N512 NSH configuration.
-    * drivers/analog and include/nuttx/analog: Add ADC driver infrastructure
-      and TI ADS1255 driver developed and submitted by Li Zhouy (Lzzy)).
-    * arch/arm/stm32/stm32_sdio.h and drivers/mmcsd/mmcsd.c:  Add logic to
-      multiplex usage of the GPIO pins (contributed by Uros Platise).
-    * configs/twr-k60n512/nsh:  Added and verified a NuttShell (NSH)
-      configuration for the Freescale, Kinetis TWR-K60N512 board.
+    * arch/arm/src/kinetis/kinetis_sdhc.c: SDHC driver for Kinetis parts.
+      Initially check-in is just a crude port of the STM32 SDIO driver.
+      Much more work is needed.
+    * graphics/, include/nuttx/nx:  Add new NX interfaces for drawing
+      circles -- both circular outlines and filled circles.
+    * graphic/nxglib/nxglib_spitline.c:  Add a &quot;fudge factor&quot; that eliminates
+      some problems for rendering nearly horizontal, wide lines.  Hmm...
+      but I suspect this fudge factor also leads to new problems rendering
+      very thin, nearly horizontal lines.  More tuning is needed.
+    * drivers/analog, include/nuttx/analog, arch/arch/src/lpcxx:  (1) Add
+      updates to the ADS1255 driver, (2) fix errors from my last merge (sorry),
+      (3) Add DAC infrastructure, (4) add AD5410 DAC driver, and (5) add
+      LPC17xx ADC and DAC drivers.  All contributed by Li Zhuoyi (Lzyy).
+    * tools/mkexport.sh:  Extended the script that implements the top-level
+      'make export' logic.  The script now also finds and bundles up all of
+      the architecture-specific header files as well.
+    * drivers/arch/arm/src/stm32/stm32_i2c.c:  Add a reset to the I2C
+      initialization logic to prevent spurious interrupts when the I2C
+      interrupts are enabled (submitted by Uros Platise).
+    * Scripts/makefiles/documents.  Several adjustments, corrections and
+      typo fixes so that NuttX will build correctly on FreeBSD using the
+      ASH shell (submitted by Kurt Lidl).
+    * drivers/mtd/flash_eraseall.c:  Add a callable function that accepts
+      the path to a block driver and then erases the underlying FLASH memory
+      (assuming that the block driver is an MTD driver wrapped in the FTL
+      layer).  Hmmm... this is probably not the best long term solution;
+      flash_eraseall() should be a user-callable function that operates
+      one driver interfaces; not an internal, OS function that operates
+      on directly on block drivers.
+    * drivers/bch:  Fixed some important bugs in the BCH driver (noted by
+      Li Zhuoyi (Lzyy)).  This would have effected any large reads or writes
+      (larger than the hardware sector size).
+    * arch/*/src/Makefile:  Use of -print-libgcc-file-name to get path to
+      libgcc.a may select the wrong libgcc.a if a multilib toolchain (like
+      CodeSourcery) is used. This can be a serious problem and can cause
+      crashes on Cortex-M3 if the ARM libgcc is used, for example.  The fix 
+      is to include ARCHCPUFLAGS on the gcc command line when asking it to
+      -print-libgcc-file-name.
+    * lib/time/lib_gmtimer.c:  Correct several calculations that could lead
+      to errors in dates.
+    * drivers/pm: Add the beginnings of a NuttX power management sub-system.
+    * arch/arm/src/stm32/stm32_irq.c:  Fix a error introduced in 6.8.
+      Timeout calculation uses clock_settime() instead of clock_gettime().
+      Pretty gross error, but actually it works with the side effect of setting
+      a bad time.
+    * drivers/mtd/at24xx.c: Driver for I2C-based at24cxx EEPROM submitted by
+      Li Zhuoyi (Lzyy).
+    * arch/arm/src/lpc17xx/lpc17_i2c.c: I2C driver for the NXP LPC17xx family
+      submitted by Li Zhuoyi (Lzyy)
+    * arch/arm/src/stm32_i2c.c:  Correct two issues with the STM32 I2C driver:
+      (1) Clocking needs to be based on PCLK1, not HCLK and fast speed settings
+      need some additional bits; and (2) Correct a hang that will occur on
+      I2C1 if FSMC is also enabled.
+    * drivers/sensors/lm75.c and include/nuttx/sensors/lm75.h:  Add an LM-75
+      temperature sensor driver.
+    * configs/stm3210e-eval/src/up_lm75.c:  Add support for the LM-75 on the
+      STMicro STM3210E-EVAL board.
+    * sched/clock_gettime.c:  Correct an error in the tv_nsec calculation
+      that happens only config CONFIG_RTC is enabled.
+    * arch/arm/src/stm32/stm32_i2c.c:  Correct some bugs related to waiting
+      to the I2C STOP condition to be cleared.
