<p><b>nuttx-6.1 Release Notes</b>:
|

|
||||
<p>

The 67<sup>th</sup> release of NuttX, Version 6.0, was made on March 21, 2011 and is available for download from the
|
||||
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:
|
||||
</p>
|
||||
<ul>
|
||||
<li><code>nuttx-6.0.tar.gz</code>, and</li>
|
||||
<li><code>apps-6.0.tar.gz</code></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.
|
||||
</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:
|
||||
</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>
|
||||
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:
|
||||
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>
|
||||
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?
|
||||
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 QEMU i486 port is now functional.
|
||||
It has also been reported to work on the <a href="http://bifferos.bizhat.com/">Bifferboard</a>.
|
||||
The <code>apps/</code> directory build system would not handle Windows-native toolchains due to obscure path formatting issues.
|
||||
</li>
|
||||
<li>
|
||||
And extensions to the uIP driver interface, and
|
||||
And other problems as detailed in the change log.
|
||||
</li>
|
||||
<li>
|
||||
Bug fixes to <code>fopen()</code> and STM32 GPIO configuration
|
||||
</li>
|
||||
<li>
|
||||
</ul>
|
||||
|
||||
<p>
|
||||
Please see the ChangeLog for details.
|
||||
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>
|
||||
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>
|
||||
<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>
|
||||
Additional new features in this release:
|
||||
</p>
|
||||
<ul>
|
||||
<li>
|
||||
Support for LPC17xx GPIO interrupts (with much support from Decio Renno).
|
||||
</li>
|
||||
<li>
|
||||
Basic timer support for STM32 (Contributed by Uros Platise)
|
||||
</li>
|
||||
<li>
|
||||
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>
|
||||
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>
|
||||
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/<board>/<config>/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
