The goal is to provide implementations of most standard POSIX OS interfaces
|
||
to support a rich, multi-threaded development environment for deeply embedded
|
||
processors.
|
||
</p>
|
||
NON-GOALS: It is not a goal to provide the level of OS features like those provided by Linux.
|
||
In order to work with smaller MCUs, small footprint must be more important than an extensive feature set.
|
||
But standard compliance is more important than small footprint.
|
||
Surely a smaller RTOS could be produced by ignoring standards.
|
||
Think of NuttX is a tiny Linux work-alike with a much reduced feature set.

weak symbols when available.

NuttX strives to achieve a high degree of standards compliance.
|
||
The primary governing standards are POSIX and ANSI standards.
|
||
Additional standard APIs from Unix and other common RTOS's are
|
||
adopted for functionality not available under these standards
|
||
or for functionality that is not appropriate for the deeply-embedded
|
||
RTOS (such as <code>fork()</code>).
|
||
</p>
|
||
<p>
|
||
Because of this standards conformance, software developed under other
|
||
standard OSs (such as Linux) should port easily to NuttX.

syntax, breaking compatibility to existing programs. Bas offers many ANSI

BASIC statements for structured programming, such as procedures, local

variables and various loop types. Further there are matrix operations,

automatic LIST indentation and many statements and functions found in

<b>Look at all those files and features... How can it be a tiny OS?</b>.
|
||
The NuttX feature list (above) is fairly long and if you look at the NuttX
|
||
source tree, you will see that there are hundreds of source files comprising
|
||
NuttX. How can NuttX be a tiny OS with all of that?

The philosophy behind that NuttX is that lots of features are great... <i>BUT</i>
|
||
also that if you don't use those features, then you should not have to pay a penalty
|
||
for the unused features.
|
||
And, with NuttX, you don't! If you don't use a feature, it will not
|
||
be included in the final executable binary.
|
||
You only have to pay the penalty of increased footprint for the features
|
||
that you actually use.
|
||
</p>
|
||
<p>
|
||
Using a variety of technologies, NuttX can scale from the very tiny to
|
||
the moderate-size system. I have executed NuttX with some simple applications
|
||
in as little as 32K <i>total</i> memory (code and data).
|
||
On the other hand, typical, richly featured NuttX builds require more like 64K
|
||
(and if all of the features are used, this can push 100K).

One may be intimidated by the size NuttX source tree. There are hundreds of source files!
|
||
How can that be a tiny OS?
|
||
Actually, the large number of files is one of the tricks to keep NuttX small and
|
||
as scalable as possible.
|
||
Most files contain only a single function.
|
||
Sometimes just one tiny function with only a few lines of code.
|
||
Why?
|
||
</p>
|
||
<ul>
|
||
<li>
|
||
<b>Static Libraries</b>.
|
||
Because in the NuttX build processed, objects are compiled and saved into
|
||
<i>static libraries</i> (<i>archives</i>).
|
||
Then, when the file executable is linked, only the object files that are needed
|
||
are extracted from the archive and added to the final executable.
|
||
By having many, many tiny source files, you can assure that no code that you do
|
||
not execute is ever included in the link.
|
||
And by having many, tiny source files you have better granularity --
|
||
if you don't use that tiny function of even just a few lines of code, it will
|
||
not be included in the binary.

<p>
|

As mentioned above, the use of many, tiny source files and linking from static
|
||
libraries keeps the size of NuttX down.
|
||
Other tricks used in NuttX include:
|
||
</p>
|
||
<ul>
|
||
<li>
|
||
<b>Configuration Files</b>.
|
||
Before you build NuttX, you must provide a configuration file that specifies
|
||
what features you plan to use and which features you do not.
|
||
This configuration file contains a long list of settings that control
|
||
what is built into NuttX and what is not.
|
||
There are hundreds of such settings
|
||
(see the <a href="NuttXConfigVariables.html">Configuration Variable Documentation</a>
|
||
for a partial list that excludes platform specific settings).
|
||
These many, many configuration options allow NuttX to be highly tuned to
|
||
meet size requirements.
|
||
The downside to all of these configuration options is that it greatly
|
||
complicates the maintenance of NuttX -- but that is my problem, not yours.
|
||
</li>
|
||
<li>
|
||
<b>Weak Symbols</b>
|
||
The GNU toolchain supports <i>weak</i> symbols and these also help to keep
|
||
the size of NuttX down.
|
||
Weak symbols prevent object files from being drawn into the link even if they
|
||
are accessed from source code.
|
||
Careful use of weak symbols is another trick for keep unused code out of the
|
||
final binary.

</p>
|

<ul>
|

<li>
|
||
<p>
|
||
First, a 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 (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 (<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.

<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.

Basic support is in place for both the LPC3152 MCU and the EA3152 board.

Verification of the port was deferred due to tool issues
|

However, because of the high degree of compatibility between the LPC313x and LPC315x family, it
|
||
is very likely that the support is in place (or at least very close).
|

At this point, verification of the EA3152 port has been overcome by events and

may never happen.

However, the port is available for anyone who may want to use it.

<b>Atmel SAMA5D3 Xplained development board</b>
|
||
This is the port of NuttX to the Atmel SAMA5D3 Xplained development board.
|
||
The board features the Atmel SAMA5D36 microprocessor.
|
||
See the <a href="http://www.atmel.com/devices/sama5d36.aspx">Atmel Website</a> for additional information about this board.
|
||
</p>
|
||
<p>
|
||
<b>STATUS</b>.
|
||
This port is complete as of this writing and ready for general use.
|
||
The basic port is expected to be simple because of the similarity to the SAMAD3<i>x</i>-EK boards and is available in the NuttX 7.2 release.
|
||
</p>
|
||
<p>
|
||
Most of the drivers and capabilities of the SAMA5D3x-EK boards can be used with the SAMA5D3 Xplained board.
|
||
The primary difference between the ports is that the SAMA5D3x-EK supports NOR FLASH and NuttX can be configured to boot directly from NOR FLASH.
|
||
The SAMA5D3 Xplained board does not have NOR FLASH and, as a consequence NuttX must boot into SDRAM with the help of U-Boot.

</p>
|
||
<p><b>STATUS</b>.
|
||
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).
|

<p>
|
||
<b>STATUS</b>.
|
||
Initial support for the NUC120 was released in NuttX-6.26.
|
||
This initial support is very minimal:
|
||
There is a NuttShell (<a href="NuttShell.html">NSH</a>) configuration that might be the basis for an application development.
|
||
As of this writing, more device drivers are needed to make this a more complete port.
|
||
Refer to the NuttX board <a href="https://bitbucket.org/nuttx/nuttx/src/master/boards/arm/nuc1xx/nutiny-nuc120/README.txt" target="_blank">README</a> file for further information.
|
||
</p>
|
||
<p>
|
||
<b>Memory Usage</b>.
|
||
For a full-featured RTOS such as NuttX, providing support in a usable and meaningful way within the tiny memories of the NUC120 demonstrates the scalability of NuttX. The NUC120LE2AN comes in a 48-pin package and has 128KB FLASH and 16KB of SRAM.
|
||
When running the NSH configuration (itself a full up application), there is still more than 90KB of FLASH and 10KB or SRAM available for further application development).
|
||
</p>
|
||
<p>
|
||
Static memory usage can be shown with <code>size</code> command:
|
||
</p>
|
||
<ul><pre>
|
||
$ size nuttx
|
||
text data bss dec hex filename
|
||
35037 106 1092 36235 8d8b nuttx
|
||
</pre></ul>
|
||
<p>
|
||
NuttX, the NSH application, and GCC libraries use 34.2KB of FLASH leaving 93.8KB of FLASH (72%) free from additional application development.
|
||
Static SRAM usage is about 1.2KB (<4%) and leaves 14.8KB (86%) available for heap at runtime.
|
||
SRAM usage at run-time can be shown with the NSH <code>free</code> command:
|
||
</p>
|
||
<ul><pre>
|
||
NuttShell (NSH) NuttX-6.26
|
||
nsh> free
|
||
total used free largest
|
||
Mem: 14160 3944 10216 10216
|
||
nsh>
|
||
</pre></ul>
|
||
<p>
|
||
You can see that 10.0KB (62%) is available for further application development.

<p>STM32L-Discovery</b>.
|
||
This is a port of NuttX to the STMicro STM32L-Discovery development board.
|

The STM32L-Discovery board is based on the STM32L152RBT6 MCU (128KB FLASH and 16KB of SRAM).
|
||
</p>
|
||
<p>
|
||
The STM32L-Discovery and STM32L152C DISCOVERY kits are functionally equivalent.
|
||
The difference is the internal Flash memory size (STM32L152RBT6 with 128 Kbytes or STM32L152RCT6 with 256 Kbytes).

<p>
|

<b>STATUS</b>.
|

Initial support for the STM32L-Discovery was released in NuttX-6.28.
|
||
Addition (architecture-only) support for the STM32L152xC family was added in NuttX-7.21.

</p>
|
||
<p>
|
||
That initial STM32L-Discovery support included a configuration using the NuttShell (<a href="NuttShell.html">NSH</a>) that might be the basis for an application development.
|
||
A driver for the on-board segment LCD is included as well as an option to drive the segment LCD from an NSH "built-in" command.

<b>Memory Usage</b>.
|
||
<blockquote><small>
|
||
REVISIT: These numbers are out of date. Current NuttX sizing might be somewhat larger.
|
||
</small></blockquote>
|
||
For a full-featured RTOS such as NuttX, providing support in a usable and meaningful way within the tiny memories of the STM32L152RBT6 demonstrates the scalability of NuttX. The STM32L152RBT6 comes in a 64-pin package and has 128KB FLASH and 16KB of SRAM.
|
||
</p>
|
||
<p>
|
||
Static memory usage can be shown with <code>size</code> command:
|
||
</p>
|
||
<ul><pre>
|
||
$ size nuttx
|
||
text data bss dec hex filename
|
||
39664 132 1124 40920 9fd8 nuttx
|
||
</pre></ul>
|
||
<p>
|
||
NuttX, the NSH application, and GCC libraries use 38.7KB of FLASH leaving 89.3B of FLASH (70%) free from additional application development.
|
||
Static SRAM usage is about 1.2KB (<4%) and leaves 14.8KB (86%) available for heap at runtime.
|
||
</p>
|
||
SRAM usage at run-time can be shown with the NSH <code>free</code> command:
|
||
<ul><pre>
|
||
NuttShell (NSH) NuttX-6.27
|
||
nsh> free
|
||
total used free largest
|
||
Mem: 14096 3928 10168 10168
|
||
nsh>
|
||
</pre></ul>
|
||
<p>
|
||
You can see that 9.9KB (62%) of SRAM heap is still available for further application development while NSH is running.

|
||
A configuration to support the NuttShell is also included.
|
||
NuttX version 5.4 adds support for the HX8347 LCD on the SAM3U-EK board.
|
||
This LCD support includes an example using the
|
||
<a href=" http://www.nuttx.org/Documentation/NXGraphicsSubsystem.html">NX graphics system</a>.
|

|
||
</li>
|
||
<li>
|

verified using the NuttX OS test (<code>apps/examples/ostest</code>).
|
||
Configurations available include include a verified NuttShell (NSH) configuration

<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.

<b>OmnibusF4</b>.
|
||
Initial support for the OmnibusF4 family of flight management units was contributed by Bill Gatliff in NuttX-7.29.
|
||
"OmnibusF4" is not a product name <i>per se</i>, but rather a design specification that many product vendors adhere to.
|
||
The specification defines the major components, and how those components are wired into the microcontroller.
|
||
<i>Airbot</i> is one such vendor. They publish a <a href="http://bit.ly/obf4pro">schematic</a>.
|
||
Other software that supports the OmnibusF4 family include Betaflight, iNAV, and many others.
|
||
PX4 recently added support as well, also based on NuttX.
|
||
No code from those resources is included in this port.
|
||
The OmnibusF4 specifcation mandates the InvenSense MPU6000 which is included in NuttX-7.29 along with a driver for the MAX7546 OSD.

|
||
<p><b>NuttX-6.20</b>
|
||
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>

<b>Memory Usage</b>.
|
||
The ATSAM4LC4C comes in a 100-pin package and has 256KB FLASH and 32KB of SRAM.
|
||
Below is the current memory usage for the NSH configuration (June 9, 2013).
|
||
This is <i>not</i> a minimal implementation, but a full-featured NSH configuration.
|
||
</p>
|
||
<p>
|
||
Static memory usage can be shown with <code>size</code> command:
|
||
</p>
|
||
<ul><pre>
|
||
$ size nuttx
|
||
text data bss dec hex filename
|
||
43572 122 2380 46074 b3fa nuttx
|
||
</pre></ul>
|
||
<p>
|
||
NuttX, the NSH application, and GCC libraries use 42.6KB of FLASH leaving 213.4B of FLASH (83.4%) free from additional application development.
|
||
Static SRAM usage is about 2.3KB (<7%) and leaves 29.7KB (92.7%) available for heap at runtime.
|
||
</p>
|
||
SRAM usage at run-time can be shown with the NSH <code>free</code> command.
|
||
This runtime memory usage includes the static memory usage <i>plus</i> all dynamic memory allocation for things like stacks and I/O buffers:
|
||
<ul><pre>
|
||
NuttShell (NSH) NuttX-6.28
|
||
nsh> free
|
||
total used free largest
|
||
Mem: 29232 5920 23312 23312
|
||
</pre></ul>
|
||
<p>
|
||
You can see that 22.8KB (71.1%) of the SRAM heap is still available for further application development while NSH is running.

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 <a href="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.
|
||

Extension of the AVR architecture to support the ATMega2560 and specifi support for the Arduion MEGA2560 board were contributed by Dimitry Kloper and first released in NuttX-7.14.
|
||
</p>
|
||
<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.

<p><b>AVR-Specific Issues</b>.
|
||
The basic AVR port is solid.
|
||
The biggest issue for using AVR is its tiny SRAM memory and its Harvard architecture.
|
||
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.
|
||
</p>
|
||
<p>
|
||
Most NuttX test applications are console-oriented with lots of strings used for <code>printf()</code> and debug output.
|
||
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.
|
||
So, in order for the AVR port to be useful, one of two things would need to be done:
|
||
</p>
|
||
<ol>
|
||
<li>
|
||
Don't use console applications that required lots of strings.
|
||
The basic AVR port is solid and your typical deeply embedded application should work fine.
|
||
Or,
|
||
</li>
|
||
<li>
|
||
Create a special version of printf that knows how to access strings that reside in FLASH (or EEPROM).
|
||

<b>STATUS:</b>
|
||
This port is has completed all basic development, but there is more that needs to be done.
|
||
All code is complete for the basic NuttX port including header files for all AT32UC3* peripherals.
|
||
The untested AVR32 code was present in the 5.12 release of NuttX.
|
||
Since then, the basic RTOS port has solidified:
|
||
</p>
|
||
<ul>
|
||
<li>
|
||
The port successfully passes the NuttX OS test (apps/examples/ostest).
|
||
</li>
|
||
<li>
|
||
A NuttShell (NSH) configuration is in place (see the <a href="http://www.nuttx.org/Documentation/NuttShell.html">NSH User Guide</a>).
|
||
Testing of that configuration has been postponed (because it got bumped by the Olimex LPC1766-STK port).
|
||
Current Status: I think I have a hardware problem with my serial port setup.
|
||
There is a good chance that the NSH port is complete and functional, but I am not yet able to demonstrate that.
|
||
At present, I get nothing coming in the serial RXD line (probably because the pins are configured wrong or I have the MAX232 connected wrong).
|
||
</li>
|
||
</ul>
|
||
<p>
|
||
The basic, port was be released in NuttX-5.13.
|
||
A complete port will include drivers for additional AVR32 UC3 devices -- like SPI and USB --- and will be available in a later release,
|
||
time permitting.

This port is available as of release 0.3.18 of NuttX. The port is basically complete

and many examples run correctly. However, there are remaining instabilities that
|

make the port un-usable. The nature of these is not understood; the behavior is
|
||
that certain SH-1 instructions stop working as advertised. This could be a silicon
|
||
problem, some pipeline issue that is not handled properly by the gcc 3.4.5 toolchain
|
||
(which has very limit SH-1 support to begin with), or perhaps with the CMON debugger.
|
||
At any rate, I have exhausted all of the energy that I am willing to put into this cool
|

old processor for the time being.

<b>XTRS: TRS-80 Model I/III/4/4P Emulator for Unix</b>.
|
||
A very similar Z80 port is available for <a href="http://www.tim-mann.org/xtrs.html">XTRS</a>,
|
||
the TRS-80 Model I/III/4/4P Emulator for Unix.
|
||
That port also uses the <a href="http://sdcc.sourceforge.net/">SDCC</a> toolchain
|
||
under Linux or Cygwin (verified using version 2.6.0).
|
||
</p>
|
||
<ul>
|
||
<p>
|
||
<b>STATUS:</b>
|
||
Basically the same as for the Z80 instruction set simulator.
|
||
This port was contributed by Jacques Pelletier.
|
||
Refer to the NuttX board <a href="https://bitbucket.org/patacongo/obsoleted/src/master/configs/xtrs/README.txt" target="_blank">README</a> file for further information.
|
||
</p>
|
||
<p>
|
||
<b>NOTE:</b>
|
||
This port was removed from the NuttX source tree on 2017-11-24.
|
||
It was removed because (1) it is unfinished, unverified, and unsupported, and (2) the TRS-80 simulation is a sub-optimal platform.i
|
||
That platform includes a 16-bit ROM image and only a 48Kb RAM space for NuttX.
|
||
The removed board support is still available in the <code>Obsoleted</code> repository if anyone would ever like to resurrect it.

This is a tougher environment.
|
||
In this case, the Windows native toolchain is unaware of the
|
||
Cygwin <i>sandbox</i> and, instead, operates in the native Windows environment.
|
||
The primary difficulties with this are:
|
||
</p>
|
||
<ul>
|
||
<li>
|
||
<b>Paths</b>.
|
||
Full paths for the native toolchain must follow Windows standards.
|
||
For example, the path <code>/home/my\ name/nuttx/include</code> my have to be
|
||
converted to something like <code>'C:\cygwin\home\my name\nuttx\include'</code>
|
||
to be usable by the toolchain.
|
||
</li>
|
||
<p>
|
||
Fortunately, this conversion is done simply using the <code>cygpath</code> utility.
|
||
</p>
|
||
<li>
|
||
<b>Symbolic Links</b>
|
||
NuttX depends on symbolic links to install platform-specific directories in the build system.
|
||
On Linux, true symbolic links are used.
|
||
On Cygwin, emulated symbolic links are used.
|
||
Unfortunately, for native Windows applications that operate outside of the
|
||
Cygwin <i>sandbox</i>, these symbolic links cannot be used.
|
||
</li>
|
||
<p>
|
||
The NuttX make system works around this limitation by copying the platform
|
||
specific directories in place.
|
||
These copied directories make work a little more complex, but otherwise work well.
|
||
</p>
|
||
<p><small>
|
||
NOTE: In this environment, it should be possible to use the NTFS <code>mklink</code> command to create links.
|
||
This should only require a minor modification to the build scripts (see <code>tools/copydir.sh</code> script).
|
||
</small></p>
|
||
<li>
|
||
<b>Dependencies</b>
|
||
NuttX uses the GCC compiler's <code>-M</code> option to generate make dependencies. These
|
||
dependencies are retained in files called <code>Make.deps</code> throughout the system.
|
||
For compilers other than GCC, there is no support for making dependencies in this way.
|
||
</li>
|
||
<p><small>
|
||
NOTE: dependencies may be suppressed by setting the make variable <code>MKDEPS</code> to point
|
||
to the do-nothing dependency script, <code>tools/mknulldeps.sh</code>.
|
||
</small></p>
|
||
</ul>
|
||
<p>
|
||
<b>Supported Windows Native Toolchains</b>.
|
||
At present, the following Windows native toolchains are in use:
|
||
<ol>
|
||
<li>GCC built for Windows (such as CodeSourcery, Atollic, devkitARM, etc.),</li>
|
||
<li>SDCC built for Windows,</li>
|
||
<li> the ZiLOG XDS-II toolchain for Z16F, z8Encore, and eZ80Acclaim parts.</li>

This build:

|

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.

|

</p>
|
||
<ul>
|
||
<li>
|
||
<b>Windows Console</b>.
|
||
The build must be performed in a Windows console window.
|
||
This may be using the standard <code>CMD.exe</code> terminal that comes with Windows.
|
||
I prefer the ConEmu terminal which can be downloaded from:
|
||
http://code.google.com/p/conemu-maximus5/
|
||
</li>
|
||
<li>
|
||
<b>GNUWin32</b>.
|
||
The build still relies on some Unix-like commands.
|
||
I usethe GNUWin32 tools that can be downloaded from http://gnuwin32.sourceforge.net/.
|
||
See the top-level <code>nuttx/README.txt</code> file for some download, build, and installation notes.
|
||
</li>
|
||
<li>
|
||
<b>MinGW-GCC</b>.
|
||
MinGW-GCC is used to compiler the C tools in the <code>nuttx/tools</code> directory that are neede by the build.
|
||
MinGW-GCC can be downloaded from http://www.mingw.org/.
|
||
If you are using GNUWin32, then it is recommended that you not install the optional MSYS components as there may be conflicts.

I've never tried this one, but I off the following reported by an ez80 user using the ZiLOG ZDS-II Windows-native toolchain:

|
||
I've tried nsh profile and build process completed successfully.
|
||
One remark is necessary: NuttX makefiles for ez80 are referencing <code>cygpath</code> utility.
|
||
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:

<b>Environment Dependencies</b>.
|
||
The primary environmental dependency of NuttX are (1) GNU make,
|
||
(2) bash scripting, and (3) Linux utilities (such as cat, sed, etc.).
|
||
If you have other platforms that support GNU make or make
|
||
utilities that are compatible with GNU make, then it is very
|
||
likely that NuttX would work in that environment as well (with some
|
||
porting effort). If GNU make is not supported, then some significant
|
||
modification of the Make system would be required.
|
||
</p>
|
||
<p>
|
||
<b>MSYS</b>.
|
||
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.
