This 61<sup>st</sup> release of NuttX, Version 5.14, was made on November 27, 2010 and is available for download from the
<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>
Headlines for this release include:
This release includes multiple, important bugfixes as well as a new driver for the NXP LPC1766.
Important bugfixes include:
<ul>
<li>
<p>
AVR32, www.mcuzone.com AVR32DEV1
<ul>
<p>
The port for the www.mcuzone.com AVRDEV1 board based on the Atmel
AT32UC3B0256 MCU was (almost) fully integrated. The port now
successfully passes the NuttX OS test (examples/ostest). A
NuttShell (NSH) configuration is in place (see the
<a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
Testing of that NSH configuration, however, has been postponed
(because it got bumped by the Olimex LPC1766-STK port -- see below)
</p>
<p>
Current Status: I think I have a hardware problem with my serial
port setup. There is a good chance that the NSH port is complete
and functional, but I am not yet able to demonstrate that. At
present, I get nothing coming in the serial RXD line (probably
because the pins are configured wrong or I have the MAX232
connected wrong).
</p>
<p>
A complete port will include drivers for additional AVR32 UC3
devices -- like SPI and USB --- and will be available in a later
release, time permitting.
</p>
</ul>
</p>
<li>
Cortex-M3 Hard Fault.
Fixed a hard fault problem that can occur if certaintypes of interrupts are pending at the time another interrupt returns.
This problem has only been observed on the LPC1766 (returning from a SYSTICK interrupt with a pending Ethernet interrupt).
However, it is assumed that all Cortex-M3 ports could have this as a latent bug.
</li>
<li>
<p>
LPC1766, Olimex LPC1766-STK
<ul>
<p>
Support for the Olimex-LPC1766 is newly added to NuttX and is
still undergoing development, test, and integration. Verified
configurations for the NuttX OS test and for the NuttShell (NSH,
see the <a href="ttp://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
Additional USB configurations are in the release as well, but
they have not yet been verified. Goals for NuttX-5.14 include:
(1) An Ethernet driver, (2) Verified USB support, and (3) SD
card support.
</p>
</ul>
</p>
</li>
<li>
Additional changes and bugfixes as detailed in the ChangeLog.
<li>
TCP/IP Sequence Number Bug.
Corrected errors some important logic in the way that sequence numbers are managed when <code>send()</code> sends out packets before a previous packet has been acknowledged.
Some of that send() logic was incompatible with logicin the uIP layer.
Errors seen include:
(1) The final final packet in a sequence of packets might be too large!
In the THTTPD example, this might leave some garbage at the bottom of the display.
Or (2) <code>send()</code> might hang with outstanding, unacknowledged data (and with no re-transmission requests).
This was due to differences in sequence number handling in <code>send()</code> and in <code>uip_tcpinput.c</code>;
<code>uip_tcpinput.c</code> thought (incorrectly) that all of the bytes were acknowledged;
<code>send.c</code> knew that they were not.
</li>
<li>
One-Shot POSIX Timer Bug.
Fixed an error in set-up of a one-shot POSIX timer.
It was using the repititive timer value (which is zero in the one-shot case), always resulting in a 10Ms timer!
Found and fixed by Wilton Tong.
</li>
</ul>
</p>
<p>
Additional support has been included for the Olimex-LPC1766.
Support for that board was added to NuttX 5.13.
This release extends that support with an Ethernet driver.
Verified configurations are now available for the NuttX OS test,
for the NuttShell (NSH, see the <a href="ttp://www.nuttx.org/NuttShell.html">NSH User Guide</a>),
for the NuttX network test, and for the <a href="http://acme.com/software/thttpd">THTTPD</a> webserver.
(Additional USB configurations are in the release as well, but those have not yet been verified).
Goals for NuttX-5.15 (and beyond) include: (1) Verified USB support, (2) SD card support, and (3) LCD support.

* lib/lib_strnlen.c -- Added POSIX 2008 strnlen() function. Contributed
by Michael Hrabanek.
* Fix wild, consistent naming error. For some reason, I called the at32uc3*
parts at91uc* everywhere. Fixed by changing lots of files and directories.
* configs/avr32dev1/ostest - The AVR32 port now successfully passes the
examples/ostest. We have a good AVR32 port!
* configs/avr32dev1/nsh - Added a configuration to support the NuttShell
(NSH). As of this writing, here is a problem receiving serial data (this
is, very likely, my hardware setup).
* lib/lib_open.c - Fix an error in fdopen when a valid file desciptor does
not refer to an open file.
* configs/olimex-lpc1766stk - Add support for the Olimex LPC1766-STK
development board. The OS test and NSH configurations (only) have been
verified.
* configs/olimex-lpc1766stk/nettest - Add examples/nettest configuration to
verify the LPC17xx ethernet driver currently under development.
* arch/arm/src/lpc17xx/lpc17xx_ethernet.c/.h - Began development of
the LPC17xx Ethernet driver. Driver in CVS functional after 2010-11-23.
* sched/timer_settime.c - Fix an error in set-up of a one-shot POSIX timer. It
was using the repititive timer value (which is zero in the one-shot case),
always resulting in a 10Ms timer! Found and fixed by Wilton Tong.
* arch/arm/src/lpc17xx/lpc17_vector.S, stm32/stm32_vector.S, lm3s/lm3s_vector.S,
sam3u/sam3u_vector.S -- Fixed a hard fault problem that can occur if certain
types of interrupts are pending at the time another interrupt returns
(SYSTICK). This has not been verified on all plaforms, but is a critical
fixed that is needed by all Cortex-M3 NuttX users.
* configs/olimex-lpc1766stk/thttpd - Add a THTTPD configuration for the
Olimex LPC2766-STK board. Verified successfully.
* net/uip/uip_tcpappsend.c - Correct an important logic bug in some uIP state
data the is used to manage retransmissions. The uIP logic was incompatible
with the retransmission logic of net/send.c in one place. The final error
was that the final packet in a sequence of packets was too large! In the
THTTPD example, this would leave some garbage at the bottom of the display
(or worse). I don't know why I haven't see this bug before???
* net/uip/uip_tcpinput.c -- The change to uip_tcpappsend.c unmasked an
additional error in the TCP sequence number handling. This sympom was that
the send() function would hang with outstanding, unacknowledged data (with
no re-transmit requests). The was due to differences in sequence number
handling in send() and in uip_tcpinput.c; uip_tcpinput.c thought (incorrectly)
that all of the bytes were acknowledged; send.c knew that they were not.
