+  The 68<sup>th</sup> release of NuttX, Version 6.1, was made on April 10, 2011 and is available for download from the
   <a href="http://sourceforge.net/projects/nuttx/files/">SourceForge</a> website.
   The change log associated with the release is available <a href="#currentrelease">here</a>.
   Unreleased changes after this release are available in SVN.
   These unreleased changes are listed <a href="#pendingchanges">here</a>.
 </p>
 <p>
-  The version number of this release was bumped from 5.19 to 6.0.
-  A change in the major revision number is used to reflect an incompatibility with previous versions.
-  In this release, the NuttX core OS functionality has been separated from NuttX application-related functionality.
-  These are provided as separate tarballs:
+  The 6.0 release introduced a detach-able application environment to build applications outside of the NuttX source tree.
+  The primary purpose of this release is to correct numerous build problems introduced by that architectural change:
 </p>
 <ul>
-  <li><code>nuttx-6.0.tar.gz</code>, and</li>
-  <li><code>apps-6.0.tar.gz</code></li>
+  <li>
+    In many newer environments, NuttX produced strange Makefile errors but built correctly in older environments.
+    A fix provided by Rafael Norinha was incorporated and is reported to fix those build problems.
+  </li>
+  <li>
+    The <code>apps/</code> directory build system would not handle Windows-native toolchains due to obscure path formatting issues.
+  </li>
+  <li>
+    And other problems as detailed in the change log.
+  </li>
 </ul>
+
 <p>
-  The purpose of this separation is both to better organize and modularize the NuttX source tree,
-  but also to provide better support for incorporation of end-user applications with Nuttx.
+  Many additional changes were made in the 6.1 release for another major architectural change:
+  NuttX will now build as a seperately linked micro-kernel.
+  In this build option the RTOS builds as a kernel, applications build separtate and interface with kernel via system calls.
+  Applications run in user mode and kernel logic users in kernel-mode.
+  This provides a secure environment for NuttX.
+  This feature is fully coded in NuttX-6.1, but has not been tested due to higher priority tasks that have arisen.
 </p>
 <p>
-  The incompatibily results from the changes to the board configuration logic needed to supported the separable application. 
-  The major changes to the configuration include:
+  Related to this change, support for the Cortex-M3 memory protection unit (MPU) has been integrated with the NuttX kernel build to provide an even higher level of security.
 </p>
-<ul>
-  <li><code>CONFIG_APPS_DIR</code> - This should not, typically be set.
-    The default is <code>../apps</code>. 
-    This should only be set if you have a custom, product-specific application directory in some different location.
-  </li>
-  <li><code>appconfig</code> - Each board configuration now requires a new file called <code>appconfig</code>.
-    As its name suggests, this file provides new configuration information needed by the logic in <code>../apps</code>.
-  </li>
-</ul>
+<p><small>
+  NOTE: This kernel build is an option; the default build configuration is still the standard, flat, unsecured RTOS as in previous releases.
+</small></p>
 <p>
-  In addition to this major reorganization in the directory structure, this release also includes some important extensions to existing features and
-  some important bugfixes.
-  These include:
+  Additional new features in this release:
 </p>
 <ul>
   <li>
-    The SLIP driver was been well debugged and significantly re-designed.
-    Now you can have an Ethernet connection to you board even if you have no Ethernet hardware.
-    How cool is that?
+    Support for LPC17xx GPIO interrupts (with much support from Decio Renno).
   </li>
   <li>
-    The QEMU i486 port is now functional.
-    It has also been reported to work on the <a href="http://bifferos.bizhat.com/">Bifferboard</a>.
+    Basic timer support for STM32 (Contributed by Uros Platise)
   </li>
   <li>
-    And extensions to the uIP driver interface, and
+    A binfs file system.
+	This is a tiny psuedo file system that lets named appliations to be viewed and accessed in NSH under the <code>/bin</code> directory.
   </li>
   <li>
-    Bug fixes to <code>fopen()</code> and STM32 GPIO configuration
+    An I2C-based driver for the LIS331DL MEMS motion sensor (Contributed by Uros Platise).
   </li>
   <li>
+    A board configuration for the Embedded Artists LPCXpresso LPC1768 board.
+  </li>
+  <li>
+    The <code>user_initialize()</code> interface has been removed.
+  </li>
 </ul>
+
 <p>
-  Please see the ChangeLog for details.
+  And several bugfix are included.
+  This includes chagnes associated with SD drivers, openddir(), signed 8-bit types (<code>int8_t</code>), and USB serial device.  See the ChangeLog for details.

+  ------------------------------

+

+  If using LPCLink as your debug connection, first of all boot the LPC-Link using

+  the script:

+

+    bin\Scripts\bootLPCXpresso type

+

+  where type = winusb for Windows XP, or type = hid for Windows Vista / 7.

+

+  Now run the flash programming utility with the following options

+

+    flash_utility wire -ptarget -flash-load[-exec]=filename [-load-base=base_address]

+

+  Where flash_utility is one of:

+

+    crt_emu_lpc11_13 (for LPC11xx or LPC13xx parts)

+    crt_emu_cm3_nxp (for LPC17xx parts)

+    crt_emu_a7_nxp (for LPC21/22/23/24 parts)

+    crt_emu_a9_nxp (for LPC31/32 and LPC29xx parts)

+    crt_emu_cm3_lmi (for TI Stellaris LM3S parts

+

+  wire is one of:

+

+    (empty) (for Red Probe+, Red Probe, RDB1768v1, or TI Stellaris evaluation boards)

+    -wire=hid (for RDB1768v2 without upgraded firmware)

+    -wire=winusb (for RDB1768v2 with upgraded firmware)

+    -wire=winusb (for LPC-Link on Windows XP)

+    -wire=hid (for LPC-Link on Windows Vista/ Windows 7)

+

+  target is the target chip name. For example LPC1343, LPC1114/301, LPC1768 etc.

+

+  filename is the file to flash program. It may be an executable (axf) or a binary

+  (bin) file. If using a binary file, the base_address must be specified.

+

+  base_address is the base load address when flash programming a binary file. It

+  should be specified as a hex value with a leading 0x.

+

+  Note:

+  - flash-load will leave the processor in a stopped state

+  - flash-load-exec will start execution of application as soon as download has

+    completed.

+

+  Examples

+    To load the executable file app.axf and start it executing on an LPC1758

+	target using Red Probe, use the following command line:

+

+      crt_emu_cm3_nxp -pLPC1758 -flash-load-exec=app.axf

+

+    To load the binary file binary.bin to address 0x1000 to an LPC1343 target

+	using LPC-Link on Windows XP, use the following command line:

+

+      crt_emu_lpc11_13_nxp -wire=hid -pLPC1343 -flash-load=binary.bin -load-base=0x1000
