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: (1) 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.
|
|
(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).

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.
|
|
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.

<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.

<li>
|
|
Added an option to conditionally disable the "wfi" sleep mode. This
|
|
is needed with certain JTAG debuggers to to prevent the debug
|
|
session from begin disconnected (from Ken Pettit).
|
|
</li>
|
|
<li>
|
|
Added support for the STM32L (STM32L15X/STM32L16x) family.
|
|
</li>
|
|
<li>
|
|
Added STM32F103C4 and F103C8 chip support (from Laurent Latil).
|
|
</li>
|
|
<li>
|
|
Added a new interface function, <code>stm32_dmacapable()</code> that can be used
|
|
to determine if DMA is possible from the specified memory address
|

<b>STM32 Drivers</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
If <code>CONFIG_STM32_DMACAPABLE</code> is defined, the STM32 SPI driver now uses
|
|
<code>stm32_dmacapable()</code> to determine if it is possible to perform DMA
|
|
from the specified address. This change is important for the STM32
|
|
F4 which may have SPI data buffers allocated on the stack in CCM
|
|
memory which cannot support the DMA (from Petteri Aimonen).

|
|
touchscreen. Several graphics configurations are included.
|
|
</li>
|
|
<li>
|
|
The HY-mini STM32v board now uses the common SSD1289 driver
|
|
and supported the card detect interrupt. Several new
|
|
configurations also added and some removed (from Laurent Latil).
|
|
</li>
|
|
<li>
|
|
Support added for the R65105-based LCD that comes with some
|
|
HY-Mini STM32v boards (from Christian Faure).
|
|
</li>
|
|
<li>
|
|
Added basic support for the STM32L-Discovery board. Drivers
|
|
for the on-board segment LCD are included.
|
|
</li>
|
|
<li>
|
|
Added support for the STM32 Tiny development board based on the
|
|
STM32 F103C8T6 MCU. This includes support for the nRF24L01+
|
|
wireless on the board (from Laurent Latil).

|
Reorganized, renamed, and updated directory structure to better
|
|
support additional members of the SAM3/4 family.
|
|
</li>
|
|
<li>
|
|
Added support for both the ATSAM4S and ATSAM4L families. The
|
|
ATSAM4S is similar to the ATSAM3U, but the ATSAM4L is quite a
|
|
different beast, really much more akin to the AVR32s SoCs but
|
|
with a Cortex-M4.

<b>Build System</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Clean-up of almost all <code>.gitignore</code> files: Made scope of ignore to be
|
|
only the current directory; Ignore <code>.dSYM</code> files in directories where
|
|
<code>.exe</code>'s may be built. Also, in <code>Makefile</code>s, clean <code>.dSYM</code> files in
|
|
directories where an <code>.exe</code> may be built.
|
|
</li>
|
|
<li>
|
|
Standardize and consolidated all build-as-an-NSH-application
|
|
configuration settings. Now only<code> CONFIG_NSH_BUILTIN_APPS</code> is
|
|
sufficient to build an application, test, or or example as an NSH
|
|
builtin application.
|
|
</li>
|
|
<li>
|
|
Added support for a generic ARM, ARMv6-M and ARMv7-M Windows EABI
|
|
toolchains.

|
|
<p>
|
|
<b>Libraries</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Added encoder/decoder logic to marshal and serialize special segment
|
|
LCD (SLCD) commands intermixed with normal ASCII data. This is the
|
|
similar to the encoding/decoding logic that is used to marshal
|
|
special commands from a keyboard.
|
|
</li>
|
|
<li>
|
|
Add <code>dprintf()</code> and <code>vdprintf()</code> (the latter from Andrew Tridgell).
|
|
</li>
|
|
<li>
|
|
Add an application that may be built as an NSH builtin command that
|
|
will erase FLASH using a <code>flash_eraseall</code> NSH command (from Ken Pettit).
|
|
</li>
|
|
</ul>

|
|
<p>
|
|
<b>Applications</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Added an MTD partition <code>test/examples</code>. Currently used with (1) the a
|
|
simulation configuration to test MTD partitions on a RAM emulation
|
|
of FLASH and (2) with the Mikroe STM32F4 configuration.
|
|
</li>
|
|
<li>
|
|
Added a test/example to verify alphanumeric, segment LCDs.
|
|
</li>
|
|
<li>
|
|
Added a simple single threaded, poll based TCP echo server based
|
|
on W. Richard Stevens UNIX Network Programming Book (from Max
|
|
Holtzberg).
|
|
</li>
|
|
<li>
|
|
Added several tests of the <i>SMART</i> block driver and file system (from
|
|
Ken Pettit).
|
|
</li>
|
|
<li>
|
|
Added a runtime configuration for the UDP discover utility (from
|
|
Max Holtzberg).
|
|
</li>
|
|
<li>
|
|
Added an example application to demo the nRF24L01 driver (from
|
|
Laurent Latil).
|
|
</li>
|
|
<li>
|
|
New and modified NSH commands:
|
|
<ul>
|
|
<li>
|
|
Added a -h option to the df command to show the volume information in human readable form (from Ken Petit).
|
|
</li>

<b>Audio System</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
A complete audio subsystem include CODECs, higher level management,
|
|
interface definitions, and audio drivers was contributed by Ken
|
|
Pettit. This work has not been completely verified as of this
|
|
release and so is categorized as a work-in-progress. At present,
|
|
progress is blocked due to issues interfacing with the VS1053
|
|
audio DAC on the Mikroe STM32F4 board.

|
<b>kconfig-fronted Configuration</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Conversion of old configurations to use the kconfig-frontends

tool is an ongoing effort that will continue for some time.
|
|
At this time, only 43% of the configurations have been converted
|
|
to use the kconfig-frontends tools.

<ul>
|
|
<li>
|
|
Typo in syscall proxying logic corrected by Ken Pettit.

<p>
|
|
<b>Networking</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Poll setup/teardown logic should ignore invalid (i.e., negative)
|
|
file descriptors (from Max Holtzberg).
|
|
</li>
|
|
<li>
|
|
When readahead data is available, the network <code>poll()</code> logic should
|
|
set <code>POLLIN</code> (or <code>POLLRDNORM</code>), not <code>POLLOUT</code> (from Max Holtzberg).
|
|
</li>

|
</ul>
|
|

<p>
|
|
<b>LCD Drivers</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Correct power controls in the MIO283QT2 LCD driver.

<p>
|
|
<b>USB Device Controller Drivers</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Change the default IN request buffer size from 64 to 96. This will
|
|
avoid requests of exactly MAXPACKET size and, hence, avoid so many
|
|
NULL packets. Also, fix the OUT request buffers size to exactly the
|
|
max packet size. It really cannot be any other size.
|
|
</li>
|
|
</ul>

|
<p>
|
|
<b>STM32 Drivers</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Correct some bad STM32 F1 DMA definitions that crept into the system
|
|
a few months ago a broke STM32 F1 DMA (from Laurent Latil)
|
|
</li>
|
|
<li>
|
|
Fixed an error in NULL packet handling in the STM32 F1 USB device
|
|
controller driver: If the NULL-packet needed flag ever got set,
|
|
then it was not being cleared and infinite NULL packets resulted.
|
|
This only affects the CDC/ACM class and was the cause of the
|
|
failures using the USB CDC/ACM device as a NuttX console. With this
|
|
change the USB works well as an alternative NuttX console device for
|
|
the STM32 F1 family.
|
|
</li>
|
|
<li>
|
|
Correct some bad condition compilation in the RCC logic (CONFIG_
|
|
missing from setting names). This affects some STM32 FLASH pre-
|
|
fetch settings (from Lorenz Meier).
|
|
</li>
|
|
<li>
|
|
Change for hardware flow control support for STM32. The change also
|
|
fixes incorrect operation of USART2 and UART5 in current master
|
|
(from Lorenz Meier and Mike Smith).
|
|
</li>
|
|
<li>
|
|
Fixed a backward conditional in USB OTG FS host controller driver
|
|
that prevented detection of disconnection events (from Scott).

|
<b>PIC32MX</b>
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Fix NULL packet handling in the PIC32 USB device driver. Without
|
|
this fix the CDC/ACM driver cannot be used reliably with the PIC32
|
|
USB. With this change the USB works well as an alternative NuttX
|
|
console device.

<b>Graphics</b>
|
|
</p>
|

|
|
Default priorities for NxWidget and NxWM threads should be 100,

</p>
|
|
<ul>
|
|
<li>
|
|
Remove the <code>CONFIG_EXAMPLES_NXTEXT_NOGETRUN</code> option from the NXTEXT
|
|
example. The test logic was bad for the case where this options is
|
|
not selected. Also, completed the empty Kconfig file.
|
|
</li>
|
|
<li>
|
|
C++ name mangling was occurring when this example is built as an NSH
|
|
built-in application causing the entry to be undefined when called
|
|
from C code.
|
|
</li>
|

with console output visible on UART0, and the NuttShell (<a href="NuttShell.html">NSH</a>)
|
|
is fully functional with interrupt driven serial console. An SPI driver is available

|
SD cards).
|
|
An SPI-based ENC28J60 Ethernet driver for add-on hardware is available and

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>).

Support for <a href="NuttXDemandPaging.html">on-demand paging</a> has been developed for the EA3131.

Support for the NXP <a href="http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/">LPC315x</a> family has been incorporated into the code base as of NuttX-6.4.
|
|
Support has added for the Embedded Artists EA3152 board in NuttX-6.11.
|
|
</p>
|
|
<ul>
|
|
<p>
|
|
<b>STATUS:</b>
|
|
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.
|
|
Refer to the NuttX board <a href="http://sourceforge.net/p/nuttx/git/ci/master/tree/nuttx/configs/ea3152/README.txt">README</a> file for further information.

This is a port of NuttX to the nuvoTon NuTiny-SDK-NUC120 that features the NUC120LE3AN MCU.
|
|
</p>
|
|
<ul>
|
|
<p>
|
|
<b>STATUS</b>.
|
|
Initial support for the NUC120 was released in NuttX-6.26.
|
|
This initial support is very minimal:
|
|
There is an OS test configuration that verifies the correct port of NuttX to the part and
|
|
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="http://sourceforge.net/p/nuttx/git/ci/master/tree/nuttx/configs/nutiny-nuc120/README.txt">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

|
|

|
|
</pre></ul>
|
|
<p>
|
|
You can see that 10.0KB (62%) is available for further application development.

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>
|
|
<ul>
|
|
<p>
|
|
The STM32L-Discovery and 32L152CDISCOVERY kits are functionally equivalent.
|
|
The difference is the internal Flash memory size (STM32L152RBT6 with 128 Kbytes or STM32L152RCT6 with 256 Kbytes).
|
|
Both boards feature:
|
|
</p>
|
|
<ul>
|
|
<li>An ST-LINK/V2 embedded debug tool interface,</li>
|
|
<li>LCD (24 segments, 4 commons),</li>
|
|
<li>LEDs,</li>
|
|
<li>Pushbuttons,</li>
|
|
<li>A linear touch sensor, and</li>
|
|
<li>Four touchkeys.</li>
|
|
</ul>
|
|
<p>
|
|
<b>STATUS</b>.
|
|
Initial support for the STM32L-Discovery was released in NuttX-6.28.
|
|
This initial support includes 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.
|
|
As of this writing, a few more things are needed to make this a more complete port: 1) Verfication of more device drivers (timers, quadrature encoders, PWM, etc.), and 2) logic that actually uses the low-power consumption modes of the EnergyLite part.
|

<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>

<p><b>NuttX-6.20</b>
|
|
The basic port is complete.
|
|
The OS test configuration and the basic NSH configurations are present and fully verified.
|
|
This includes verified support for: SYSTICK system time, pin and GPIO configuration, and a serial console.
|
|
</p>
|
|
<p>
|
|
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:
|
|
<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 poriting 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.

<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 staill available for further application development while NSH is running.

<p><b>AVR-Specific Issues</b>.
|
|
The basic AVR port is solid and 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 printf 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.

This port uses the www.mcuzone.com AVRDEV1 board based on the Atmel AT32UC3B0256 MCU.
|
|
This port requires a special GNU avr32 toolchain available from atmel.com website.
|
|
This is a windows native toolchain and so can be used only under Cygwin on Windows.
|
|

<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 (including the verified apps/examples/ostest configuration) 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.

The P112 is a hobbyist single board computer based on a 16MHz Z80182 with up to 1MB of memory, serial,
|
|
parallel and diskette IO, and realtime clock, in a 3.5-inch drive form factor..
|
|
The P112 computer originated as a commercial product of "D-X Designs Pty Ltd"[ of Australia.
|
|
</p>
|
|
</p>
|
|
Dave Brooks was successfully funded through Kickstarter for and another run of P112 boards in November of 2012.
|
|
In addition Terry Gulczynski makes additional P112 derivative hobbyist home brew computers.
|

|
<ul>
|
|
<p>
|
|
<b>STATUS:</b>
|
|
Most of the NuttX is in port for both the Z80182 and for the P112 board.
|
|
Boards from Kickstarter project will not be available, however, until the third quarter of 2013.
|
|
So it will be some time before this port is verified on hardware.

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.
|
|
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>.
|
|
</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>

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.

At present, this build environment also requires:
|
|
</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 recommendedthe you not install the optional MSYS components as there may be conflicts.

|
|
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:

|
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.

|
|
negative) file descriptors. Max Holtzberg (2013-5-23).
|
|
* net/net_poll.c: When readahead data is available, the network poll
|
|
logic should set POLLIN (or POLLRDNORM), not POLLOUT. Max Holtzberg
|
|
(2013-5-23)

|
|
and serialize special SLCD intermixed with normal ASCII data (2013-5-23)
|
|
* configs/stm32ldiscovery/src/stm32_lcd.c: STM32L-Discovery's segment LCD
|
|
is code complete but completely untested (2013-5-23).
|
|
* include/nuttx/fs/ioctl.h, include/nuttx/lcd/slcd_codec.h, and
|
|
configs/stm32ldiscovery/src/stm32_lcd.c: Add SLCD ioctl commands to get
|
|
SLCD geometry, set bars, and manage contrast (2013-5-23).
|
|
* configs/stm32ldiscovery/src/stm32_usb.c: This file and all references
|
|
to USB removed for the STM32L-Discovery. While the chip supports a
|
|
USB device, the board does not (2013-5-24).
|
|

|
|
includes instructions for adding the apps/examples/slcd segment LCD
|
|
test as an NSH "built-in" command (2013-5-24).
|
|
* configs/pcblogic-pic32mx: Converted all configurations to use the
|
|
kconfig-frontends tool (2013-5-25).
|
|
* configs/pcblogic-pic32mx/src: Renamed files using pic32mx_ vs up_
|
|
prefix. Enable building of LCD1602 LCD (2013-5-25).
|
|
* configs/pcblogic-pic32mx/src/pic32mx_lcd1602.c: Now uses SLCD CODEC
|
|

|
|
* configs/stm32ldiscovery/src/stm32_lcd.c: Now supports ioctl to get
|
|
cursor position (2013-5-25).
|
|
* include/nuttx/lcd/slcd_ioctl.h: Moved ioctls commands and structures
|
|
from slcd_codec.h (2013-5-25)
|
|

|
|
and decoding bug fixes (2013-5-26)
|
|
* configs/sure-pic32mx: Converted all configurations to use the
|
|
kconfig-frontends tools, cleaned up the directory structure and
|
|
naming to match some of the more recent configurations, and added
|
|
a segment LCD driver for the board. The initial checkin of the
|
|
LCD driver is just a clone of configs/pcblogic-pic32mx/src/pic32mx_lcd1602
|
|
and it not yet expected to be functional (2013-5-26).
|
|
* include/nuttx/lcd/slcd_ioctl.h and all SLCD drivers: Rename geometry
|
|
structure to attributes; Move MAX contrast to attributes. Add
|
|
attribute and ioctl commands to get and set LCD brightness (2013-5-27).
|
|
* configs/sure-pic32mx/pic32mx_lcd1602.c: This driver appears to
|
|
fully functional (at least to the extent that it has been tested)
|
|
(2013-5-27).
|
|
* arch/mips/src/pic32mx/pic32mx-usbdev.c: Fix NULL packet handling in
|
|
the PIC32 USB device driver. Without this fix the CDC/ACM driver
|
|
cannot be used reliably with the PIC32 USB. With this change the
|
|
configs/sure-pic32mx/usbnsh configuration works great (2013-5-28).
|
|
* configs/sure-pic32mx/src/pic32mx_nsh.c: The NSH configurations will
|
|
support the USB monitor applications (2013-5-28).
|
|
nuttx/arch/arm/include/stm32/chip.h, src/stm32/Kconfig, src/stm32/chip.h,
|
|
and src/stm32/chip/stm32f103c_pinmap.h: STM32F103C4 and F103C8 chip
|
|
support from Laurent Latil (2013-5-28)
|
|
* configs/stm32_tiny: Add support for the STM32 Tiny development board
|
|
based on the STM32 F103C8T6 MCU (2013-5-28).
|
|
* arch/arm/src/stm32/stm32_usbdev.c: Fix an error in NULL packet
|
|
handling: If the NULL-packet needed flag ever gets set, then
|
|
it is not cleared and inifinite NULL packets result. This only
|
|
effects the CDC/ACM class and was the cause of the failure of
|
|
configs/stm32f3discovery/usbnsh configureation which works great
|
|
after this change (2013-5-29).
|
|
* drivers/usbdev/cdcacm.c and pl2303.c and include/nuttx/usb/cdcacm.h:
|
|
Change the default IN request buffer size from 64 to 96. This will
|
|
avoid requests of exactly MAXPACKET size and, hence, avoid so many
|
|
NULL packets. Also, fix the OUT request buffers size to exactly
|
|
the max packet size. It cannot be any other size (2013-5-29).
|
|
* .gitignore: Clean-up of most all .gitignore files: Make scope of
|
|
ignore to be only the current directory; Ignore .dSYM files in
|
|
directories where .exe's may be build. Also, in Makefiles,
|
|
clean .dSYM files in directories where .exe may be built (2013-5-30).
|
|
* drivers/wireless/nrf24101.c/.h and include/nuttx/wireless/nrf24101.h:

|
to this subdirectory. Naming of registers changed from SAM3U_ to
|
|
just SAM_. This is in preparation for a SAM4L port (2013-6-2).
|
|
* arch/arm/src/sam3u: Renamed files to sam_* vs. sam3u_*.

|
|
configs/mikroe-stm32f4/src/up_clockconfig.c. Correct some bad
|
|
conditional compilation (CONFIG_ missing from setting name). This
|
|
affects some STM32 FLASH pre-fetch settings. From Lorenz Meier
|
|
(2013-6-2).
|
|
* arch/arm/include/sam34 and arch/arm/src/sam34: The old sam3u/

stm32_dmacapable() that can be used to determine if DMA is
|
|
possible from the specified memory address. From Petteri Aimonen
|
|
(2013-6-4).
|
|
* arch/arm/src/stm32/stm32_spi.c: If CONFIG_STM32_DMACAPABLE is
|
|
defined, use stm32_dmacapable() to determine if it is possible
|
|
to perform DMA from the specified address. This change is
|
|
important for the STM32 F4 which may have SPI data buffers
|
|
allocated on the stack in CCM memory which cannot support the
|
|
DMA. From Petteri Aimonen (2013-6-4).
|
|

|
|
|
|
* NxWM::CMediaPlayer: shell application for an MP3 Media Player with
|
|
Kconfig settings to enable it. I plan to write this app to help
|
|
develop and test the MP3 codec chip driver. It really doesn't do
|
|
anything yet except display a text box saying "Coming soon", and I
|
|
need to minimize the icon size a bit. From Ken Pettit (2013-5-11).
|
|
* NxWidgets/nxwm/src/glyph_mediaplayer.cxx: Smaller version of the
|

|
|
to prevent dereferencing the NULL pointer. From Petteri Aimonen
|
|
(2013-6-4).
|
|
* NxWidgets::CNumericEdit: Delay before auto-incrementing now varies:
|
|
A longer delay is required to start auto-incrementing and speed increases
|
|
while pressed. From Petteri Aimonen (2013-6-4).
|
|
* NxWM::CTaskbar: Add a method to redraw the taskbar and the current
|
|
application. This should only be necessary if the display loses

|
state due to e.g. powerdown or other manual intervention. From
|
|
Petteri Aimonen (2013-6-4).
|
|
|
|

|
* Add support for a Cortex-M0 toolchain based on GCC 4.6.3.
|
|
|
|
pascal-3.0 2011-05-15 Gregory Nutt <gnutt@nuttx.org>
|
|
|
|
* nuttx/: The Pascal add-on module now installs and builds under the
|
|
apps/interpreters directory. This means that the pascal-2.1 module is
|
|
incompatible with will all releases of NuttX prior to nuttx-6.0 where the
|
|
apps/ module was introduced.
