<li><p> <li>
NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation Kit. This port adds support for the RiT displays P14201 4-bpp, greyscale OLED.
At present, that port includes an OS test configuration and a NuttShell 4-bpp greyscale support was integrated into the NX graphics sub-system and
(NSH) configuration with telnet support. verified using the TI/Luminary LP3S6965 Ethernet Evaluation Kit.

in this release: Current development efforts are focused on porting the </li>
NuttX window system (NX) to work with the Evaluation Kits OLED display. <li>
</p></li> An I2C driver and (basic) SPI driver were added for the NXP LPC313x port.

available in the source tree (but has not yet been fully verified because </li>
I haven't properly connected it to hardware yet).
</p></li>
<li><p>
The Olimex STR-P711 NuttX port was extended to support the ENC28J60 and
some new networking configurations were added. The ENC28J60 has not
been tested on the STR-P711, however, because of hardware issues (I don't
think the USB powered board provides enough power for the ENC28J60 and
I don't have the right wall wart yet).
</p></li>
<li><p>
Along the way, external interrupt support (XTI) was added to the STMicro
STR-P711 port and some important bugs were fixed in the STR-P711 SPI
driver.
</p></li>
<li><p>
Corrected an important UDP reference counting error. It was not a serious
error, but it trigger an assertion was IS a serious error.
</p></li>
</ul> </ul>
</p> </p>
<p>
As well as a few, important USB-related bugfixes (See the ChangeLog for details).
</p>
<p>
This release also includes the beginnings of a port for the NXP LPC1768 MCU. However,
it is too early for that port to be useful (stay tuned for a future announcement of the
availability of the verified LPC1768 port).
