<b>TI Stellaris LM3S6432S2E</b>.
This port uses Serial-to-Ethernet Reference Design Kit (<a href="http://www.ti.com/tool/rdk-s2e">RDK-S2E</a>)
and has similar support as for the other Stellaris family members.
Configurations are available for the OS test and for the NuttShell (NSH)
(see the <a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
The NSH configuration including networking support with a Telnet NSH console.

managing the state of the application directory while in the NuttX directory
* Documentation/NuttXGettingStarted.html: Added a "Getting Started" Guide
* Documentation/NuttXGettingStarted.html: Added a &quot;Getting Started&quot; Guide

* arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct an value used as the lower
end of an IRQ number range test.
* arch/arm/src/lpc17xx/lpc17_gpio.c: Fix a integer flow problem in shift.
This error would prevent pins &gt; 15 from being used as interrupt sources.
* arch/arm/src/stm32/stm32_can.c: The CAN driver has been verified in
loopback mode on the STM3240G-EVAL board.
* configs/stm3240g-eval/src/up_adc.c: Complete coding of ADC support for the
potentiometer on board the STM3240G-EVAL.
* arch/arm/src/lpc17_can.c: Several CAN driver improvements. Adds support for
testing in loopback mode. now uses all three transmit buffers for better
performance.
* confgs/olimex-lpc1766stk/nsh: Now supports the CAN loopback test as an
optional &quot;built-in&quot; application.
* sched/irq_attach.c: Fix an issue with disabling interrupts when they are
detached. For the PIC32, this can't be done because there is a 1-to-many
relationship between vector numbers and interrupt numbers or different.
Added a new configuration option CONFIG_ARCH_VECNOTIRQ to at least flag
the architectures that have this issue and to (at least) avoid doing
something too wrong.
* drivers/can.c: Fix a test for buffer full in the generic, &quot;upper half&quot;,
can driver.

* 3. The handle returned by up_spiinitialize() may then be used to bind the
