First, a port for the NXP <ahref="http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/">LPC3131</a> on the <ahref="http://www.embeddedartists.com/products/kits/lpc3131_kit.php">Embedded Artists EA3131</a> development board was first released in NuttX-5.1 (but was not functional until NuttX-5.2).
</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 (<ahref="NuttShell.html">NSH</a>).
</p>
<p>
Support for <ahref="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.
Refer to the Embedded Artists EA3131 board <ahref="https://bitbucket.org/nuttx/nuttx/src/master/configs/ea3131/README.txt"target="_blank">README</a> file for further information.
A second port to the NXP <ahref="http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/">LPC3131</a> on the <ahref="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.

At the time of the release of NuttX-7.3, the basic port for the SAMA5D4-MB was complete.
The board had basic functionality.
But full functionality was not available until NuttX-7.4.
In NuttX-7.4 support was added for the L2 cache, many security features, XDMAC, HSMCI and Ethernet integrated with XDMAC, the LCDC, TWI, SSC, and most of the existing SAMA5 drivers.
Timers were added to support <i>Tickless</i> operation.
The TM7000 LCDC with the maXTouch multi-touch controller are also fully support in a special NxWM configuration for that larger display.
Support for a graphics media player is included (although there were issues with the WM8904 audio CODEC on my board).

<aname="lc823450"><b>ON Semiconductor LC823450 (Dual core ARM Cortex-M3)</b>.</a>
In NuttX-7.22, Masayuki Ishakawa contributed support for both the LC823450 architecture and for ON Semiconductor's <b>LC823450XGEVK board</b>:
</p>
<blockquote>
The LC823450XGEVK is an audio processing system Evaluation Board Kit used to demonstrate the LC823450. This part can record and playback, and offers High-Resolution 32-bit & 192 kHz audio processing capability. It is possible to cover most of the functions necessary for a portable audio with only this LSI as follows. It has Dual CPU and DSP with High processing capability, and internal 1656K-Byte SRAM, which make it possible to implement large scale program. And it has integrated analog functions (low-power Class D HP amplifier, PLL, ADC etc.) so that PCB space and cost is reduced, and it has various interface (USB, SD, SPI, UART, etc.) to make extensibility high. Also it is provided with various function including SBC/AAC codec by DSP and UART and ASRC (Asynchronous Sample Rate Converter) for Bluetooth® audio. It is very small chip size in spite of the multi-funciton as described above and it realizes the low power consumption. Therefore, it is applicable to portable audio markets such as Wireless headsets and will show high performance.

Several drivers have been copied from the related LPC17xx port but require integration into the LPC43xx: ADC, DAC, GPDMA, I2C, SPI, and SSP.
The registers for these blocks are the same in both the LPC43xx and the LPC17xx and they should integrate into the LPC43xx very easily by simply adapting the clocking and pin configuration logic.
</p>
<p>
Other LPC17xx drivers were not brought into the LPC43xx port because these peripherals have been completely redesigned: CAN, Ethernet, USB device, and USB host.
</p>
<p>
So then there is no support for the following LPC43xx peripherals: SD/MMC, EMC, USB0,USB1, Ethernet, LCD, SCT, Timers 0-3, MCPWM, QEI, Alarm timer, WWDT, RTC, Event monitor, and CAN.
</p>
<p>
Some of these can be leveraged from other MCUs that appear to support the same peripheral IP:
</p>
<ul>
<li>
The LPC43xx USB0 peripheral appears to be the same as the USB OTG peripheral for the LPC31xx.
The LPC31xx USB0 device-side driver has been copied from the LPC31xx port but also integration into the LPC43xx (clocking and pin configuration).
It should be possible to complete porting of this LPC31xx driver with a small porting effort.
</li>
<li>
The Ethernet block looks to be based on the same IP as the STM32 Ethernet and, as a result, it should be possible to leverage the NuttX STM32 Ethernet driver with a little more effort.
</li>
</ul>
</li>
<li>
<p><b>NuttX-6.21</b>
Added support for a SPIFI block driver and for RS-485 option to the serial driver.
</li>
<li>
<p><b>NuttX-7.17</b>
EMC support was extended to include support SDRAM by Vytautas Lukenska.
RTC and Windowed Watchdog Timer (WWDT) drivers were leveraged from the LPC17 and contributed by Gintaras Drukteinis.
Leveraged the LPC54xx SD/MMC to the LPC43xx.
There are still remaining issues with the SD/MMC driver and it is not yet functional.

The port of NuttX to Adafruit Metro M4 development board was released with NuttX-7/26.
This board is essentially a advanced version of the Adafruit Metro board based on the SAMD21, but upgraded to the SAMD51, specifically the SAMD51J19.
See the <ahref="https://www.adafruit.com/product/3382">Adafruit</a> web page for additional information about the board.
</p>
<p>
A fully-function, basic NuttShell (NSH) configuration was was available in this initial NuttX-7.26 release.
That initial port verifies clock configuration boot-up logic, SysTick timer, and SERCOM USART for the serial console.
The NSH configuration also includes use of the Cortex-M Cache Controller (CMCC) which give the SAMD51's Cortex-M4 a performance boost.
</p>
<p>
Because of the similarity in peripherals, several drivers were brought in from the SAML21 port.
Most have not been verified as of the NuttX-7.26 release.
These unverfied drivers include: SPI, I2C, DMA, USB.
Also refer to the NuttX board <ahref="https://bitbucket.org/nuttx/nuttx/src/master/configs/metro-m4/README.txt"target="_blank">README</a> file for further information about the current state of the port.
One port uses the STMicro STM32F746G-DISCO development board featuring the STM32F746NGH6 MCU. The STM32F746NGH6 is a 216MHz Cortex-M7 operation with 1024Kb Flash.

The basic NSH configuration is fully, thanks to the bring-up efforts of Mateusz Szafoni.
This port is port is still a work in progress and additional drivers are being ported from the F7 family.
This description will be updated with more current information at the time of the NuttX-7.26 release (probably September, 2018).
The initial port to the IMXRT1050-EVKB featuring the MIMXRT1052DVL6A <i>Crossover</i> MCU was included initially in NuttX-.25.
The initial port was the joint effort of Janne Rosberg, Ivan Ucherdzhiev, and myself.
Ivan gets credit for the bulk of the bring-up work and for the Hyper FLASH boot logic.

<ul>
<p>
<b>STATUS:</b>
The basic port was released in NuttX-7.14 including a simple "Hello, World!" and OS test configurations.
Extensive effort was made to the use the special capabilities of the Atmel Studio AVR compiler to retain strings in FLASH memory and so keep the SRAM memory usage to a minimum.

Because of the Harvard architecture, constant data that resides to flash is inaccessible using "normal" memory reads and writes (only SRAM data can be accessed "normally").
Special AVR instructions are available for accessing data in FLASH, but these have not been integrated into the normal, general purpose OS.
These strings are all stored in SRAM now due to these data accessing issues and even the smallest console-oriented applications can quickly fill a 4-8K memory.

This port was started and then shelved for some time until I received the Expansion I/O board.
The basic Starter Kit (even with the Multimedia Expansion Board, MEB, DM320005)) has no serial port and most NuttX test configurations depend heavily on console output.

Basic support for the RISC-V architecture was contributed by Ken Pettit in NuttX-7.19. The initial release is <i>thin</i> but a great starting point for anyone interested in RISC-V development with NuttX.
Basic architectural support for Xtensa LX6 processors and the port for the Expressif ESP32 were added in NuttX-7.19.
The basic ESP32 port is function in both single CPU and dual CPU SMP configurations.
</p>
<p>
<b>Expressif ESP32 Core v2 Board</b>
The NuttX release includes support for Expressif ESP32 Core v2 board.
There is an NSH configuration for each CPU configuration and an OS test configuration for verificatin of the port.
</p>
<p>
<b>STATUS</b>.
ESP32 support in NuttX-7.19 is functional, but very preliminary.
There is little yet in the way of device driver support.
Outstanding issues include missing clock configuration logic, missing partition tables to support correct configuration from FLASH, and some serial driver pin configuration issues.
The configuration is usable despite these limitations.

The custom NuttX <ahref="https://bitbucket.org/nuttx/buildroot/downloads/">buildroot</a> referenced above may be build in the Cygwin environment as well.
<li>Uses primarily Windows batch commands from cmd.exe, with</li>
<li>A few extensions from GNUWin32</li>
</ol>
<p>
This capability first appeared in NuttX-6.24 and should still be considered a work in progress because: (1) it has not been verfied on all targets and tools, and (2) still lacks some of the creature-comforts of the more mature environments.
"I've installed ZDS-II 5.1.1 (IDE for ez80-based boards) on wine (windows emulator for UNIX) and to my surprise, not many changes were needed to make GIT snapshot of NuttX buildable...
Wine provides similar thing called <code>winepath</code> which is compatible and offers compatible syntax.
To use that, <code>winepath</code> (which itself is a shell script) has to be copied as <code>cygpath</code> somewhere in <code>$PATH</code>, and edited as in following patch:
if [ -x "$WINELOADER" ]; then exec "$WINELOADER" "$appname" "$@"; fi
</pre></ul>
<p>
"Better solution would be replacing all <code>cygpath</code> references in <code>Makefiles </code> with <code>$(CONVPATH)</code> (or <code>${CONVPATH}</code> in shell scripts) and setting <code>CONVPATH</code> to <code>cygpath</code> or <code>winepath</code> regarding to currently used environment.
I have not used MSYS but what I gather from talking with NuttX users is that MSYS can be used as an alternative to Cygwin in any of the above Cygwin environments.
This is not surprising since MSYS is based on an older version of Cygwin (cygwin-1.3).
MSYS has been modified, however, to interoperate in the Windows environment better than Cygwin and that may be of value to some users.
</p>
<p>
MSYS, however, cannot be used with the native Windows NuttX build because it will invoke the MSYS bash shell instead of the <code>CMD.exe</code> shell.
Use GNUWin32 in the native Windows build envionment.
