<a href="http://sourceforge.net/project/showfiles.php?group_id=189573">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 CVS.
These unreleased changes are listed <a href="#pendingchanges">here</a>.
</p>
<p>
This release includes a combination of some new features as well as several bugfixes.
New features include:
This is primarily a bugfix release and includes some important corrections to the code:
<ul>
<li>
<b>TI/Luminary Stellaris LM3S9B96</b>.
Header file changes contributed by Tiago Maluta.
One very important bug fixes a race condition that can occur using
semaphores that can be awakened by signals. Under this particular
race condition, a task could hang waiting for a semaphore.
</li>
<li>
<b>TI/Luminary Stellaris LM3S8962</b>.
Header file changes and support for the Stellaris LM3S8962 Ethernet+CAN Evaluation Board contributed by Larry Arnold.
Corrections to lm3s8962 port contributed by Larry Arnold. That
port is purported to work correctly with these changes in place.
</li>
</ul>
</p>
<p>
Plus less critical bugfixes as detailed in the ChangeLog. New features
include:
<ul>
<li>
* A new configuration to support the mbed.org LPC1768 board (Contributed
by Dave Marples), and
</li>
<li>
<b>On-Demand Paging Support</b>.
The basic logic for the On-Demand Paging feature is complete, implemented for the NXP LPC3131, and partially tested.
See <a href="http://www.nuttx.org/NuttXDemandPaging.html">On-Demand Paging Documentation</a>.
Some additional test infrastructure will be needed in order to complete the verification.
See the EA3131 <a href="http://nuttx.cvs.sourceforge.net/viewvc/nuttx/nuttx/configs/ea3131/README.txt?view=log">README</a> file for details.
</li>
<li>
<b>Two Pass Build Support</b>.
The make system now supports a two pass build where a relocatable, partially linked object is created on the first pass and that object is linked with the NuttX libraris to produce the final executable on the second pass.
This two pass build is currently only used to support the On-Demand paging feature:
The first pass link forces critical logic into the locked text region;
the second pass builds the NuttX executable more-or-less as normal.
<li>
<b><code>CONFIG_APP_DIR</code></b>.
Generalized the way in which applications are built and linked with NuttX.
The new configuration <code>CONFIG_APP_DIR</code> replaces <code>CONFIG_EXAMPLE</code>.
<code>CONFIG_EXAMPLE</code> used to identify the sub-directory within the NuttX <code>examples/</code> directory that held the example application to be built.
That made it awkward to configure to build an application that resided outside of the NuttX <code>examples/</code> directory.
<code>CONFIG_APP_DIR</code> is more general;
it can be used to refer to any directory containing the application to be built.
<ul>
<p><small>
For people who have their own configurations and/or Makefiles, you will need to make a couple of changes:
<ul>
<li>
Replace all occurrences of <code>CONFIG_EXAMPLE=foobar</code> with <code>CONFIG_APP_DIR=examples/foobar</code> in all of the configuration files.
</li>
<li>
Replace any occurrences of <code>examples/$(CONFIG_EXAMPLE)</code> with <code>$(CONFIG_APP_DIR)</code>
</li>
<li>
Replace any occurrences of <code>lib$(CONFIG_EXAMPLE)$(LIBEXT)</code> with <code>libapp$(LIBEXT)</code> in your Makefiles.
</li>
<li>
Check any other occurrences of <code>CONFIG_EXAMPLE</code>.
</li>
</ul>
</small></p>
</ul>
</li>
<li>
<b>Other</b>.
Several bugfixes are included as well as code changes to eliminate some warnings.
See the ChangeLog for details.
* A driver for the Atmel AT45DB161D 4Mbit SPI FLASH part.

nuttx-5.11 2010-10-01 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* configs/ea3131/locked - Create logic to support a two pass build
process: The first pass forces critical logic into the locked text
region, the second pass builds the NuttX executable more-or-less as
normal.
* Makefile, arch/arm/src/Makefile, configs/ea3131 - Add logic to
support a two-pass final link. This logic is only in place in
the arch/arm/src/Makefile for now.
* arch/arm/src/lpc17xx/lpc17_internal.h - Add missing parentheses in
macros definitions (patch submitted by Tiago Maluta).
* Documents/NuttxPortingGuide.html, configs/README.txt, etc. -
Replaced CONFIG_EXAMPLE with CONFIG_APP_DIR (see documents for
desciption). This allows NuttX application code to be built
outside of the examples/ directory.
For people who have their own configurations and/or Makefiles,
you will need to make a couple of changes:
- Replace all occurrences of CONFIG_EXAMPLE=foobar with
CONFIG_APP_DIR=examples/foobar in all of the configuration
files.
- Replace any occurrences of examples/$(CONFIG_EXAMPLE) with
$(CONFIG_APP_DIR)
- Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT)
with libapp$(LIBEXT) in your Makefiles.
- Check any other occurrences of CONFIG_EXAMPLE.
* arch/arm/src/lpc313x/lpc313x_spi.c - Fix compilation error when
when CONFIG_DEBUG is enabled.
* arch/arm/src/lm3s and arch/arm/include/lm3s - Support for the
lm3s8962 contributed by Larry Arnold.
* configs/lm328962-ek - Support for the TI/Stellaris EKC-LM3S8962
board (also contributed by Larry Arnold).
* arch/arm/src/lpc313x/lpc313x_boot.c - The call to lpc313x_boardinitialized()
should not be conditioned on CONFIG_ARCH_LEDs being defined!
* arch/arm/src/lpc313x/ - APB0 and APB1 cannot lie in different
sections; they are too close together.
* arch/arm/src/lpc313x/lpc13x_boot.c - Resetting all of the clocking
had a side effect of wiping out the first 6 words of memory where the
interrupt vectors are located (and also not resetting the fractional
dividers). This is not usually noticeable because the IRQ vectors
are after this point, but really causes problems if you want to handle
data and prefectch aborts which are within this zeroed region.
* configs/ea3131/src/up_fillpage.c - Added new configuration item
CONFIG_PAGING_BINPATH. If CONFIG_PAGING_BINPATH is defined, then it
is the full path to a file on a mounted file system that contains
a binary image of the NuttX executable. Pages will be filled by
reading from offsets into this file that correspond to virtual
fault addresses. up_fillpage.c implements logic to perform page
files using the CONFIG_PAGING_BINPATH file.
* configs/mbed - Add configuration to support the mbed.org LPC1768
board (Contributed by Dave Marples).
* sched/sem_wait.c and sem_waitirq.c - Eliminate a race condition
that can occur when a semaphore wait is interrupt by a signal.
(see email thread: http://tech.groups.yahoo.com/group/nuttx/message/530)
* drivers/mtd/at45db.c - Add a driver for the Atmel AT45DB161D 4Mbit
SPI FLASH part (untested on initial check-in).
* arch/arm/src/lm3s and arch/arm/include/lm3s - Corrections for the
lm3s8962 port contributed by Larry Arnold. That port is purported
to work correctly with these changes in place.
* examples/ostest/prioinherit.c - Need to reinitialize globals if
test is ran repeatedly in a loop.
* configs/ez80f910200zco - Updated to used ZDS-II 4.11.1
