+ 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.

-
- * lib/lib_fopen() -- fopen() was not returning the correct errno value
- when the underlying open() failed.
- * include/net/uip/uip-arch.h -- The uIP interface has been extended
- slightly so that drivers can be concurrenly filling and sending
- packet buffers. This capability was needed by the SLIP driver.
- * drivers/net/slip.c -- Several corrections and some re-design of
- of the driver.
- * apps/ChangeLog.txt -- the apps/ directory now has its own ChangeLog.
- * configs/vsn:
- - IDLE LED blinking fix
- - Added board power off function
- * arch/arm/src/stm32/stm32_gpio.c and stm32_internal.h -- Fixed
- PullUp/Down Input Configuration.
- * arch/arm/src/lpc17xx/lpc17_serial.h -- Now supports Auto-RTS and
- Auto-CTS modes. This is needed to support SLIP.
- * drivers/net/slip.c -- SLIP is now basically functional on the
- LPC17xx with some caveats as described in the TODO list under
- LPC17xx.
- * arch/x86/include/i486/irq.h -- Fix irqrestore() macro... it was not
- correctly re-enabling interrupts.
- * arch/x86/src - Fix numerous problems with i486/QEMU context
- switching. Basically, the logic was missing the cases to handle
- the differing stack frames when a priority change occurs and when
- no priority change occurs.
- * configs/qemu-i486/ostest and nsh -- The QEMU i486 port is complete.
- it now passes the OS test and supports the NuttShell (NSH).
- * misc/drivers -- Created a new directory to hold non-BSD licensed
- drivers that may be added into NuttX via an installation script.
- * drivers/usbhost/usbhost_rtl8187.c -- A decision was made to
- incorporate code taken from the Linux kernel. That changes the
- licensing on this module to GPL. To avoid licensing contamination,
- this driver was moved to misc/drivers/rtl8187x *prior* to adding
- and of the GPL log. There is an INSTALL.sh script at the location
- where the GPL driver(s) can be re-installed into the NuttX source
- tree. By re-installing the driver, you agree to the GPL licsensing
- and all of its implications.
- * Makefile, apps/Makefile, tools/configure.sh -- add logic to copy
- configs/&lt;board&gt;/&lt;config&gt;/appdir to apps/.config and to simply the
- application configuration logic.
- * examples/nsh and apps/nshlib - Move the core NuttShell (NSH) logic
- out of the exemples directory and into the apps/directory where
- it belongs.
- * apps/Makefile and configs/*/appconfig - Use '=' as the delimiter
- instead of '/' so that sub-directories in apps/ can be used.
- * apps/vsn - Move all VSN apps to apps/vsn.
- * nuttx/examples moved to apps/examples
