This 55<sup>th</sup> release of NuttX was made on July 18, 2010 and is available for download from the
<a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a> website.

Unreleased changes after this release are available in CVS.
These unreleased changes are listed <a href="#pendingchanges">here</a>.
</p>
<p>
This release adds basic support for one new ARM Cortex-M3 architecture:
<ul>
<li>
Added support for NXP LPC1768 MCU as provided on the Nucleus 2G board from
<a href="http://www.2g-eng.com">2G Engineering</a>.
</li>
<li>
Some initial files for the LPC17xx family were released in NuttX 5.6, but the
first functional release for the NXP LPC1768/Nucleus2G occured with NuttX 5.7.
</li>
<li>
That initial basic release included timer interrupts and a serial console and was
verified using the NuttX OS test.
</li>
<li>
That release includes a verified NuttShell (NSH) configuration
(see the <a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
Also included are unverified SPI and USB device drivers.
</li>
</ul>
This includes several important bugfixes:
</p>
<ul>
<li>Corrects some interrupt vectoring for the TI/Stellarix LM3S port,</li>
<li>Correct initialization logic for NXP LPC17xxx NuttX ports: Power was not being provided to the GPIO module!</li>
<li>Corrected (but did not verify) implementation of the optional interrupt stack feature (all Cortex M3 architectures), and</li>
<li>Correct a HardFault in the LPC17xx SSP driver.</li>
</ul>
<p>
Additional minor fixes are also included as detailed in the ChangeLog.
</p>
<p>
Further efforts include: (1) development of a DMA support library, (2) SPI-based MMC/SD
support, and (3) verification of the USB driver. Watch for announcement of the completed
LPC1768 port expected in NuttX-5.8.
Several new features have been fully developed and included in this release, but
full verification of most of these new features has been blocked for a variety
of issues:
</p>
<ul>
<li>
Added microSD support for the NuttShell (NSH) configuration in the Nucleus2G LPC1768 port.
For reasons that have not yet been determined, I have not successfully accessed the microSD card as of this writing.
</li>
<li>
Two USB configurations were also added for the Nucleus2G board:
One to support the USB serial device and one for the USB mass storage device.
Some testing of the USB driver was performed, but full verification is stalled for an OTG style USB cable.
</li>
<li>
LEDs now work correctly on the Nucleus2G LPC1768 board.
</li>
<li>
The uIP-based NuttX networking subsystem now supports IGMPv2 client.
IGMP (Internet Group Multicast Protocol) network &quot;appliances&quot; to join into multicast groups.
Outbound traffic to enter and leave multicast groups has been verified, but full verification will require a switch capable of multicast.
Issues associated with the receipt of multicast packets are likely.

</ul>

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Description: If debug is enabled so that there is a lot of early serial console output,
The serial console output may be garbled initially. If this becomes a
problem during debug, I've found that just putting a delaying at the
beginning of os_start() (sched/os_start.c) eliminates the garbled output.
Status: Open
Priority: Low, only effects debug and there is a workaround
Description: Due to some connector/cabling issues using the Nucleus2g, a couple of
important features have not yet been tested: The microSD card and
USB (device). These features are fully implemented and partially
tested, but not fully verified.
Status: Open
Priority: High
Description: a) USB DMA not fully implemented. Partial logic is in place but it is
fragmentary and bogus. (Leveraged from the lpc214x)
b) Possible errors in USB device driver reported "I suspect there’s a few
issues in the lpc214x USB driver – in particular it doesn’t stall both
in/out endpoints for unsupported setup requests and it doesn’t call
CLASS_DISCONNCET on a USB reset – I don’t have any access to that hardware
so can’t pursue it really."
Status: Open
Priority: Low
Description: a) At present the SSP driver is polled. Should it be interrupt driven?
Look at arch/arm/src/imx/imx_spi.c -- that is a good example of an
interrupt driven SPI driver. Should be very easy to part that architecture
to the LPC.
b) See other SSP (SPI) driver issues listed under ARM/LPC214x. The LPC17xx
driver is a port of the LPC214x driver and probably has the same issues.
b) Other SSP driver improvements: Add support for multiple devices on the
SSP bus, use DMA data transfers
