</p> </p>
<p> <p>
This release includes multiple, important bugfixes as well as a new driver for the NXP LPC1766. This release includes several bugfixes as well as feature enhancements, primarily for the Olimex LPC1766-STK board.
Important bugfixes include: Important bugfxes included:
<ul> <ul>
<li> <li>
Cortex-M3 Hard Fault. Additional fixes needed with the TCP sequence number problem &quot;fixed&quot; in nuttx-5.14.
Fixed a hard fault problem that can occur if certaintypes of interrupts are pending at the time another interrupt returns. </li>
This problem has only been observed on the LPC1766 (returning from a SYSTICK interrupt with a pending Ethernet interrupt). <li>
However, it is assumed that all Cortex-M3 ports could have this as a latent bug. In the <code>send()</code> logic, now checks if the destination IP address is in the ARP table before sending the packet;
</li> an ARP request will go out instead of the TCP packet.
<li> This improves behavior, for example, on the first on the first GET request from a browser
TCP/IP Sequence Number Bug. </li>
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. <li>
Some of that send() logic was incompatible with logicin the uIP layer. All USB class drivers need to call DEV_CONNECT() when they are ready to be enumerated.
Errors seen include: That is, (1) initially when bound to the USB driver, and (2) after a USB reset.
(1) The final final packet in a sequence of packets might be too large! </li>
In the THTTPD example, this might leave some garbage at the bottom of the display. <li>
Or (2) <code>send()</code> might hang with outstanding, unacknowledged data (and with no re-transmission requests). The SPI_SETBITS macro was calling the SPI setmode method.
This was due to differences in sequence number handling in <code>send()</code> and in <code>uip_tcpinput.c</code>; </li>
<code>uip_tcpinput.c</code> thought (incorrectly) that all of the bytes were acknowledged; <li>
<code>send.c</code> knew that they were not. And several other bug fixes of lower criticality (see the ChangeLog for details).
</li> </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> </ul>
</p> </p>
<p> <p>
Additional support has been included for the Olimex-LPC1766. And feature enhancements:
Support for that board was added to NuttX 5.13. <ul>
This release extends that support with an Ethernet driver. <li>
Verified configurations are now available for the NuttX OS test, The LPC176x Ethernet driver was using all of AHB SRAM Bank0 for Ethernet packet buffers (16Kb).
for the NuttShell (NSH, see the <a href="ttp://www.nuttx.org/NuttShell.html">NSH User Guide</a>), An option was added to limit the amount of SRAM used for packet buffering and to re-use any extra Bank0 memory for heap.
for the NuttX network test, and for the <a href="http://acme.com/software/thttpd">THTTPD</a> webserver. </li>
(Additional USB configurations are in the release as well, but those have not yet been verified). <li>
Goals for NuttX-5.15 (and beyond) include: (1) Verified USB support, (2) SD card support, and (3) LCD support. Enabled networking and SD/MMC card support in the Olimex LPC1766-STK NuttShell (NSH) configuration.
</p> </li>
<p> <li>
Additional changes and bugfixes as detailed in the ChangeLog. The LPC176x USB driver is now fully fully functional.
</li>
<li>
Added an optional <code>cmddata()</code> method to the SPI interface.
Some devices require an additional out-of-band bit to specify if the next word sent to the device is a command or data.
The <code>cmddata()</code> method provides selection of command or data.
</li>
<li>
A driver for the Nokia 6100 LCD (with either the Phillips PCF8833 LCD controller and for the Epson S1D15G10 LCD controller)
and an NX graphics configuration for the Olimex LPC1766-STK have been added.
However, neither the LCD driver nor the NX configuration have been verified as of the this release.

nuttx-5.15
^^^^^^^^^^
The 62nd release of NuttX, nuttx-5.15, was mad on December 12, 2010. This
release includes several bugfixes as well as feature enhancements, primarily
for the Olimex LPC1766-STK board.
Important bugfxes included:
* Additional fixes needed with the TCP sequence number problem "fixed" in
nuttx-5.14.
* In the send() logic, now checks if the destination IP address is in the
ARP table before sending the packet; an ARP request will go out instead.
This improves behavior, for example, on the first on the first GET request
from a browser
* All USB class drivers need to call DEV_CONNECT() when they are ready to
be enumerated. That is, (1) initially when bound to the USB driver, and
(2) after a USB reset.
* The SPI_SETBITS macro was calling the SPI setmode method.
* And several other bug fixes of lower criticality (see the ChangeLog for
details).
And feature enhancements:
* The LPC176x Ethernet driver was using all of AHB SRAM Bank0 for Ethernet
packet buffers (16Kb). An option was added to limit the amount of SRAM
used for packet buffering and to re-use any extra Bank0 memory for heap.
* Enabled networking and SD/MMC card support in the Olimex LPC1766-STK
NuttShell (NSH) configuration.
* The LPC176x USB driver is now fully fully functional.
* Added an optional cmddata() method to the SPI interface. Some devices
require an additional out-of-band bit to specify if the next word sent
to the device is a command or data. The cmddata method provides selection
of command or data.
* A driver for the Nokia 6100 LCD (with either the Phillips PCF8833 LCD
controller and for the Epson S1D15G10 LCD controller) and an NX graphics
configuration for the Olimex LPC1766-STK have been added. However,
neither the LCD driver nor the NX configuration have been verified
as of the this release.
