<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 "appliances" 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.
|
||||

||||
