The port for the NXP <a href="http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/">LPC3131</a> on the <a href="http://www.embeddedartists.com/products/kits/lpc3131_kit.php">Embedded Artists EA3131</a>
development board was first released in NuttX-5.1 with a GNU arm-nuttx-elf or arm-eabi toolchain* under Linux or Cygwin
(but was not functional until NuttX-5.2).

<a name="nxplpc3131"><b>NXP LPC3131</b>.</a>
Two boards based on the NXP LPC3131 are supported:
</p>
<ul>
<p>
<b>STATUS:</b>
The basic EA3131 port is complete and verified in NuttX-5.2
This basic port includes basic boot-up, serial console, and timer interrupts.
This port was extended in NuttX 5.3 with a USB high speed driver contributed by David Hewson.
David also contributed I2C and SPI drivers plus several important LPC313x USB bug fixes
that appear in the NuttX 5.6 release.
This port has been verified using the NuttX OS test, USB serial and mass storage
tests and includes a working implementation of the NuttShell (<a href="NuttShell.html">NSH</a>).
</p>
<p>
Support for <a href="NuttXDemandPaging.html">on-demand paging</a> has been developed for the EA3131.
That support would all execute of a program in SPI FLASH by paging code sections out of SPI flash as needed.
However, as of this writing, I have not had the opportunity to verify this new feature.

A second port to the NXP <a href="http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/">LPC3131</a> on the <a href="https://www.olimex.com/Products/ARM/NXP/LPC-H3131/">Olimex LPC-H3131</a> development board was added in NuttX-6.32.
</p>
<ul>
<p>
<b>STATUS:</b>
The basic H3131 port is complete and verified in NuttX-6.3.
It is similar to the EA3131 port except: (1) I have not yet gotten the SDRAM to work, and (2) this board was used to develop and verify the USB 2.0, low-/full-/high-speed EHCI host controller driver.
NOTE: That driver should work on the EA3131 as well. However, the EA3131 uses a PCA9532 PWM part to controller the port power so the it would not quite be a simple drop-in.
