<b>FreeScale Kinetics K40</b>.
This port uses the Freescale Kinetis KwiStick K40.
Refer to the <a href="http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=KWIKSTIK-K40">Freescale web site</a> for further information about this board.
The Kwikstik is used with the FreeScale Tower System (mostly just to provide a simple UART connection)
</p>
<p>
<b>STATUS:</b>
As of this writing, the basic port is complete but I accidentally locked my board during the initial bringup.
Further development is stalled unless I learn how to unlock the device (or unless I get another K40).
Additional work remaining includes, among other things: (1) complete the basic bring-up,
(2) bring up the NuttShell NSH, (3) develop support for the SDHC-based SD card, and
(4) develop support for USB host and device.
NOTE: most of these remaining tasks are shared with the K60 work described below.

<b>FreeScale Kinetics K60</b>.
This port uses the Freescale Kinetis TWR-K60N512 tower system.
Refer to the <a href="http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=TWR-K60N512-KIT">Freescale web site</a> for further information about this board.
The TWR-K60N51 includes with the FreeScale Tower System which provides (among other things) a DBP UART connection.
</p>
<p>
<b>STATUS:</b>
As of this writing, the basic port is complete and passes the NuttX OS test.
Additional work remaining includes, among other things: (1) bring up the NuttShell NSH,
(2) integrate the Ethernet driver, (3) develop support for the SDHC-based SD card, and
(4) develop support for USB host and device.
NOTE: most of these remaining tasks are shared with the K40 work described above.

<b>Development Environments:</b>
1) Linux with native Linux GNU toolchain, 2) Cygwin with Cygwin GNU Cortex-M3 or 4toolchain, or 3) Cygwin with Windows native GNU Cortex-M3 or M4 toolchain (CodeSourcery or devkitARM). A DIY toolchain for Linux or Cygwin is provided by the NuttX
<a href="http://sourceforge.net/projects/nuttx/files/buildroot/">buildroot</a> package.
I use FreeScale's <i>CodeWarrior</i> IDE only to work with the JTAG debugger built into the boards.

nuttx-6.8 2011-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* arch/arm/src/lpc17xx/chip.h: Fix some chip memory configuration errors
for the LPC1764, LPC1756, and LPC1754 (submitted by Li Zhuoy (Lzzy))
* arch/arm/src/lpc17xx/lpc17_can.h: Revised CAN driver submitted by
Li Zhuoy (Lzzy). The driver now supports both CAN1 and CAN2.
* arch/arm/sim/up_lcd.c: Add a simulated LCD driver.
* configs/stm3210e-eval/nxlines: Added a configuration to build
examples/nxlines.
* arch/graphics: Used apps/examples/nxlines to (finally) verify the NX
trapezoid drawing functions and (wide) line drawing functions.
* arch/rgmp and configs/rgmp. Yu Qiang has ported RGMP to the OMAP4430 (arm)
pandaboard and release the new RGMP 0.3 version. The main changes are: (1)
Separate configs/rgmp/x86 and configs/rgmp/arm configuration directory, and
(2) Extract architecture dependent code in arch/rgmp/include and
arch/rgmp/src into corresponding x86/ and arm/ directories.
* arch/arm/src/kinetis, arch/arm/include/kinetis, configs/kwikstick-k40:
Add a directory structure to support the port to the Kinesis KwikStik-K40.
There is no real substance in the initial check-in; only the directory
structure and skeleton files (Code complete on 8/15/11).
* arch/arm/include/armv7-m, arch/arm/src/armv7-m, etc.: Rename all cortexm3
directories and files to armv7-m; Change name of of all CORTEXM3 constants
to ARMV7M. This is a major namespace change needed to cleanly support the
ARM Cortex-M4 which is also in the ARMv7 M Series (specifically, ARMv7E-M).
* sched/sig_initialize.c, sig_received.c, and mq_waitirq.c. Fixed several
critical bugs related to signal handling initialization and for signals
the wake up tasks that are waiting to send or receive message queues. In
the first two files, errors would prevent proper allocation of signal-related
structures from interrupt handlers. In the second, there was missing
"clean-up" logic after a signal occurred, leaving the message queue in
a bad state and resulting in PANICs. All are important. (submitted by
hkwilton).
* arch/arm/src/kinetis: Added header files defining all Kinetis registers
and bit fields within all Kinetis registers.
* configs/twr-k60n512: Add support for the Kinetis K60 Tower board
(TWR-K60N512).
* drivers/can.c: Fixe a semaphore overflow problem in the CAN driver
(reported by Li Zhouy (Lzzy)).
* 8/18/2011: The basic port to the FreeScale Kinetics TWR-K60N512 board is
now functional.
apps-6.8 2011-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* apps/examples/nxlines: Added a test for NX line drawing capabilities.
