<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 relese includes one new port, some new drivers and some important bugfixes:
|
||||
This release includes one several new drivers for existing NuttX ports:
|
||||
<ul>
|
||||
<li><p>
|
||||
NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation Kit.
|
||||
At present, that port includes an OS test configuration and a NuttShell
|
||||
(NSH) configuration with telnet support.
|
||||
</p>
|
||||
<p>
|
||||
MMC/SD and Networking support are provided but not thoroughly verified
|
||||
in this release: Current development efforts are focused on porting the
|
||||
NuttX window system (NX) to work with the Evaluation Kits OLED display.
|
||||
</p></li>
|
||||
<li><p>
|
||||
A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet chip is
|
||||
available in the source tree (but has not yet been fully verified because
|
||||
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>
|
||||
<li>
|
||||
This port adds support for the RiT displays P14201 4-bpp, greyscale OLED.
|
||||
4-bpp greyscale support was integrated into the NX graphics sub-system and
|
||||
verified using the TI/Luminary LP3S6965 Ethernet Evaluation Kit.
|
||||
</li>
|
||||
<li>
|
||||
The MP25Px driver was extended for the M24P1 FLASH part (see NOTE).
|
||||
</li>
|
||||
<li>
|
||||
An I2C driver and (basic) SPI driver were added for the NXP LPC313x port.
|
||||
The I2C interface definition was extended to efficiently handle multiple I2C
|
||||
transfers (See NOTE).
|
||||
</li>
|
||||
</ul>
|
||||
</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).
