<a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a> website.

</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.
+</p>

+ Additional changes and bugfixes as detailed in the ChangeLog.

- * 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.
