The goal is to provide implementations of most standard POSIX OS interfaces
|
|
|
|
|
to support a rich, multi-threaded development environment for deeply embedded
|
2007-05-09 02:06:22 +02:00

|
|
processors.

|
|
|
</p>
|
2007-05-09 02:06:22 +02:00
|
|
|
NON-GOALS: (1) It is not a goal to provide the rich level of OS
|
|
|
|
|
features like those provided with Linux.
|
|
|
|
|
Small footprint is more important than features.
|
|
|
|
|
Standard compliance is more important than small footprint.
|
2007-03-09 20:17:40 +01:00
|
|
|
(2) There is no MMU-based support for processes.
|
|
|
|
|
At present, NuttX assumes a flat address space.

Fully scalable from tiny (8-bit) to moderate embedded (32-bit).
|

Scalability with rich feature set is accomplished with:
|
|
|
|
|
Many tiny source files, link from static libraries, highly configurable, use of
|
|
|
|
|
weak symbols when available.

NuttX strives to achieve a high degree of standards compliance.
|
2007-12-05 02:27:17 +01:00
|
|
|
The primary governing standards are POSIX and ANSI standards.
|
2007-03-09 20:17:40 +01:00
|
|
|
Additional standard APIs from Unix and other common RTOS's are
|
|
|
|
|
adopted for functionality not available under these standards
|
2008-01-08 23:19:32 +01:00
|
|
|
or for functionality that is not appropriate for the deeply-embedded
|
2007-03-09 20:17:40 +01:00
|
|
|
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.

<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
|
2008-12-05 15:04:37 +01:00
|
|
|
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.
|
|
|
|

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 32Kb <i>total</i> memory (code and data).
|
2008-12-05 23:57:27 +01:00
|
|
|
On the other hand, typical, richly featured NuttX builds require more like 64Kb
|
|
|
|
|
(and if all of the features are used, this can push 100Kb).

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.

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="NuttxPortingGuide.html#apndxconfigs">NuttX Porting Guide</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.

Several new features have been fully developed and included in this release, but

|
|
|
|
full verification of most of these new features has been blocked for a variety

of issues:

|
<ul>
|
|
|
|
|
<li>
|
|
|
|
|
Added microSD support for the NuttShell (NSH) configuration in the Nucleus2G LPC1768 port.
|
|
|
|
|
For reasons that have not yet been determined, I have not successfully accessed the microSD card as of this writing.
|
|
|
|
|
</li>
|
|
|
|
|
<li>
|
|
|
|
|
Two USB configurations were also added for the Nucleus2G board:
|
|
|
|
|
One to support the USB serial device and one for the USB mass storage device.
|
|
|
|
|
Some testing of the USB driver was performed, but full verification is stalled for an OTG style USB cable.
|
|
|
|
|
</li>
|
|
|
|
|
<li>
|
|
|
|
|
LEDs now work correctly on the Nucleus2G LPC1768 board.
|
|
|
|
|
</li>
|
|
|
|
|
<li>
|
|
|
|
|
The uIP-based NuttX networking subsystem now supports IGMPv2 client.
|
|
|
|
|
IGMP (Internet Group Multicast Protocol) network "appliances" to join into multicast groups.
|
|
|
|
|
Outbound traffic to enter and leave multicast groups has been verified, but full verification will require a switch capable of multicast.
|
|
|
|
|
Issues associated with the receipt of multicast packets are likely.

This port was released in NuttX 5.5.
|
|
|
|
|
Features are the same as with the Eagle-100 LM3S6918 described above.
|
|
|
|
|
The examples/ostest configuration has been successfully verified and an
|
|
|

|
NSH configuration with telnet support is available.
|
|
|
|
|
MMC/SD and Networking support was not been thoroughly verified:
|
|
|
|
|
Current development efforts are focused on porting the NuttX window system (NX)
|
|
|
|
|
to work with the Evaluation Kits OLED display.

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

The SDCC compiler provides support for the 8051/2, z80, hc08, and other microcontrollers.

The SDCC-based logic is less well exercised and you will likely find some compilation

issues if you use parts of NuttX with SDCC that have not been well-tested.

This is a tougher environment.
|
2009-06-25 19:44:35 +02:00
|
|
|
In this case, the Windows native toolchain is unaware of the
|
2008-01-08 23:11:00 +01:00
|
|
|
Cygwin <i>sandbox</i> and, instead, operates in the native Windows environment.
|
|
|
|
|
The primary difficulties with this are:
|
|
|
|
|
</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>
|
2008-01-08 23:19:32 +01:00
|
|
|
<b>Paths</b>.
|
|
|
|
|
Full paths for the native toolchain must follow Windows standards.
|
2008-01-08 23:11:00 +01:00
|
|
|
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><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/winlink.sh</code> script).
|
|
|
|
|

|
|
|
<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.
|
|
|
|
|
For Windows native GCC compilers, the generated dependencies are windows paths and not
|
|
|
|
|
directly usable in the Cygwin make. By default, dependencies are surpressed for these
|
|
|
|
|
compilers as well.
|
|
|
|
|
</li>
|
|
|
|
|
<p><small>
|
|
|
|
|
NOTE: dependencies are suppress by setting the make variable <code>MKDEPS</code> to point
|
|
|
|
|
to the do-nothing dependency script, <code>tools/mknulldeps.sh</code>.
|
|
|
|
|
Dependencies can be enabled for the Windows native GCC compilers by setting
|
|
|
|
|
<code>MKDEPS</code> to point to <code>$(TOPDIR)/tools/mkdeps.sh --winpaths $(TOPDIR)</code>.
|
|

<b>Supported Windows Native Toolchains</b>.
|
2009-06-11 16:47:03 +02:00
|
|
|
At present, only the Zilog Z16F, z8Encore, and eZ80Acclaim ports use a non-GCC native Windows
|
|
|
|
|
toolchain(the Zilog ZDS-II toolchain).
|
|
|
|
|
Support for Windows native GCC toolchains (CodeSourcery and devkitARM) is currently implemented
|
|
|
|
|
for the NXP LPC214x, STMicro STR71x, and Luminary LMS6918 ARM ports.
|
|
|
|
|
(but could easily be extended to any other GCC-based platform with a small effort).

<b>Environment Dependencies</b>.
|
2008-01-09 23:53:52 +01:00
|
|
|
The primary environmental dependency of NuttX are (1) GNU make,
|
2009-06-11 23:38:25 +02:00
|
|
|
(2) bash scripting, and (3) Linux utilities (such as cat, sed, etc.).
|
2008-01-08 23:11:00 +01:00
|
|
|
If you have other platforms that support GNU make or make
|
|
|
|
|
utilities that are compatible with GNU make, then it is very
|
2008-01-09 23:53:52 +01:00
|
|
|
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.
|
2008-01-08 23:11:00 +01:00
|
|
|
</p>
|
2009-06-11 23:38:25 +02:00
|
|
|
<p>
|
|
|
|
|
<b>GNUWin32</b>.
|
|
|
|
|
For example, with suitable make system changes, it should be possible to
|
|
|
|
|
use native GNU tools (such as those from
|
|
|
|
|
<a href="http://sourceforge.net/projects/gnuwin32/">GNUWin32</a>)
|
|
|
|
|
to build NuttX.
|
|
|
|
|
However, that environment has not been used as of this writing.

NOTE: One of the members on the <a href="http://tech.groups.yahoo.com/group/nuttx/">NuttX forum</a>
|
|
|
|
|
reported that they successful built NuttX using such a GNUWin32-based, Windows native environment.
|
|
|
|
|
They reported that the only necessary change was to the use the NTFS mklink command to create links
|
|
|
|
|
(see <code>tools/winlink.sh</code> script).
