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.

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.
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.

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.
< / 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 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.

< / td >
< / tr >
< tr >
< td > < br > < / td >
< td >
< 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 = "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.

The 86< sup > th< / sup > release of NuttX, Version 6.19, was made on June 15, 2012, and is available for download from the
2011-02-27 19:28:49 +01:00
< a href = "http://sourceforge.net/projects/nuttx/files/" > SourceForge< / a > website.
2012-06-15 18:23:17 +02:00
Note that the release consists of two tarballs: < code > nuttx-6.19.tar.gz< / code > and < code > apps-6.19.tar.gz< / code > .
2011-07-11 16:21:05 +02:00
Both may be needed (see the top-level < code > nuttx/README.txt< / code > file for build information)

< p > < b > NFS client< / b > .
This release features new support for a Network File System (NFS) client.
This feature allows a tiny, embedded MCU to mount a remote file system exported by an NFS server and then to access the file system as it would any local file system.
Then the tiny MCU can effectively have terabyte of storage!
< / p >
< p >
This might be useful for data collection, for MCU configuration information, for software updates, for providing modular, loadable code modes, controlling a " farm" of MCUs ... there are many possibilities and opportunities for innovation!

2012-06-15 18:23:17 +02:00
The NuttShell (NSH) now supports the following command:

< / p >
2012-06-15 18:23:17 +02:00
< ul > < pre >
nfsmount < server-address> < mount-point> < remote-path>
< / pre > < / ul >
< p >
That command will mount the remote NFS server directory < remote-path> at < mount-point> on the target machine.
< server-address> is the IP address of the remote server.
2011-06-06 17:56:50 +02:00

The NFS development was the graduation project of Jose Pablo Rojas V. who is a student at the < i > Instituto Tecnol<6F> gico de Costa Rica< / i > (ITCR, or TEC).
A lot of effort went into understanding what a tiny, embedded NFS client should do and getting the target resource usage to a bare minimum.
Only around a kilobyte or so of memory is required to run the NFS client (and most of that for I/O buffers).
Jose Pablo has spent several months living with NFS and should be congratulated for his success.

Integration is complete on the basic port (boot logic, system time, serial console).
Two configurations have been verified: (1) The board boots and passes the OS test
2010-06-05 17:34:31 +02:00
with console output visible on UART0, and the NuttShell (< a href = "NuttShell.html" > NSH< / a > )
2009-10-03 01:23:55 +02:00
is fully functional with interrupt driven serial console. An SPI driver is available
2010-05-06 02:08:02 +02:00
but only partially tested. Additional features are needed: USB driver, MMC integration,
to name two (the slot on the board appears to accept on MMC card dimensions; I have only
SD cards).
An SPI-based ENC29J60 Ethernet driver for add-on hardware is under development and
2010-05-04 03:28:47 +02:00

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
2011-06-06 17:56:50 +02:00
is very likely that the support is in place (or at least very close).
2011-11-12 18:49:00 +01:00
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.

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,
(4) develop support for USB host and device, and (2) develop an LCD driver.

< 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 4-8Kb 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).

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.

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:

A NuttShell (NSH) configuration is in place (see the < a href = "http://www.nuttx.org/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.

Two configurations are available:
An OS test configuration and a that support the NuttShell (NSH).
The OS test configuration is fully functional and proves that we have a basically healthy NuttX port to the Mirtoo.
See the < a href = "http://www.nuttx.org/NuttShell.html" > NSH User Guide< / a > for further information about NSH.
There are some remaining issues to be resolved with the NSH configuration but, with any luck, the verified port should be available with the NuttX 6.20 release.

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

Also very usable is the Linux environment using the
< a href = "http://sdcc.sourceforge.net/" > SDCC< / a > compiler.
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 combination works well too.
It works just as well as the native Linux environment except
that compilation and build times are a little longer.

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 >
2010-07-03 17:32:45 +02:00
< 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).
< / small > < / p >
2009-06-11 16:47:03 +02:00
< 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 > .

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).

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.

nuttx-6.19 2012-06-15 Gregory Nutt < gnutt@nuttx.org>
* graphics/nxconsole/nxcon_kbdin.c: If selected, the NxConsole will take
input from the NX keyboard input callback. If this option is set, then
the interface nxcon_kdbin() is enabled. That interface may be driven by
window callback functions so that keyboard input *only* goes to the top
window. If CONFIG_NXCONSOLE_NXKBDIN is not selected, then the NxConsole
will receive its input from stdin (/dev/console). This works great but
cannot be shared between different windows. Chaos will ensue if you
try to support multiple NxConsole windows without CONFIG_NXCONSOLE_NXKBDIN
* graphics/nxmu/nx_kbdin.c: Fix pointer argument. This is a error
introduced in changes leading up to the 6.18 release. This error will
cause crashes or perhaps simply not work when you try to handle window
keyboard data in multi-user mode.
* graphics/nxconsole/nxcon_kdbind.c: Fixed unmatched sem_wait and sem_post.
Fix some conditional compilation that included a few too many lines of code.
* drivers/input/stmpe811_tsc.c and stmpe811.h: Add a timeout to catch missed
pen up events. Now the STM3240G-EVAL touchscreen works very smoothly.
* configs/stm3240g-eval/nxwm/defconfig: Enable support for NxConsole keyboard
input. Increasing spacing of icons.
* configs/stm3240g-eval/nxwm/defconfig: Use a larger font for the calculator.
* include/nuttx/lcd/ssd1289.h, drivers/lcd/ssd1289.c and .h: Generic LCD
driver for LCDs based on the Solomon Systech SSD1289 LCD driver. This
of this as a template for an LCD driver that will have to be cusomized
for your particular LCD hardware.
* configs/stm32f4discovery/src/up_extmem.c and up_ssd1289.c: Add support to
STM32F4Discovery for than an external, SSD1289-based LCD.
* configs/stm32f4discovery/nxlines: Add an STM32F4Discovery configuration
to thest the SSD1289-based LCD.
* configs/stm3240g-eval/src: Add USB GPIO initialization logic needed
in board-specific boot logic.
* configs/stm32f4discovery/src: Add USB GPIO initialization logic needed
in board-specific boot logic.
* drivers/usbdev/pl2303.c and cdcacm.c: Fix the request size used for sending
packets. It was not using the maximum request size, but instead the previous
request size. As a result, packets get smaller, and smaller, and ... This
is an important USB serial fix.
* arch/arc/src/stm32_otgfsdev.c: Bug fix: Don't process TXFE if we have
already processed an XFRC interrupt. We have already done what needs
to done in that case.
* arch/arc/src/stm32_otgfsdev.c: Fixed some status settings in queuing of write
messages. Added a " hack" to work around missing TxFIFO empty interrupts. The
hack is basically to poll for space in the TxFIFO instead of of setting up
the interrupt.
* arch/arm/src/stm32/stm32f2* and chip/stm32f2*: Update all STM32 F2 file so
that they are equivalent to F4 files. This is kind of a maintenance nightmare.
* configs/stm3220g-eval/: Update existing configurations to the same level
as the corresponding STM3240G-EVAL configurations. This adds FSMC SRAM,
touchscreen, and LCD support.
* configs/stm3220g-eval/: Add a NxWM configuration for the STM3220G-EVAL.
* stmpe11*: Fix a massive naming problem. All references to STMPE11 should be
STMPE812.
* arch/arm/src/stm32/stm32_otgfsdev.c: Need to enabled USB reset interrupt
(contributed by Erik Van Der Zalm).
* sched/sleep.c: Fix the return value from sleep(). The correct behavior is
to return the number of unwaited seconds; the implementation was always
returning zero.
* sched/usleep.c and include/unistd.h: Was a void function, but should return
0 on success. usleep() needs to check the return value from sigtimedwait().
sigtimewait() returns the signal number that awakened it and an error (EAGAIN)
if the timeout expired (normal case).
* sched/sig_timedwait.c: Fix sigtimedwait() return value. On a timeout, it was
setting the 8-bit si_signo field to -1 and eded up reported successfully awakened
by signal 255! Now detects the timeout and errors -1 with errno == EGAIN. If
sigtimedwait() is awakened by an unblocked signal, but it is not one of the
signals in the waited-for set, it will return -1 with errno == EINTR.
* arch/arm/src/stm32_i2c.c: Fix STM32 F2 I2C. It is apparently bug-for-bug
compatible with the F4 and needs the same work-around for the missing BTF
signal that was needed for the F4.
* drivers/lcd/ssd1289.*: Fix some of the initial register settings.
* configs/stm32f4discovery/src/up_ssd1289.c: FSMC address bit 16 is used to
distinguish command and data. But FSMC address bits 0-24 correspond to ARM
address bits 1-25, se we need to set bit 17 in order generate output on
FSMC_A16.
* arch/arm/src/lm3s/lm3s_epi.h and lm3s_timer.h: LM3S header files
(contributed by Max Neklyudov).
* arch/arm/src/stm32/stm32_irq.c: Some of the interrupt priorities were
not be initialized (F2 and F4 only). Thus, the very high numbered
interrupts (like UART6) and cause nested interrupts. This leads to
some very difficult to debug crashes. Fix contributed by Mike Smith.
* arch/mips/src/pic32/pic32_head.S and pic32_config.h and
configs/pic32mx7mmb/include/board.h: Extended PIC32 device configuration
capabilities and change board.h to support unique clocking requirements
of the Mikroelektronika PIC32MX7 MMB. That board now works!
* configs/pic32mx7mmb/nsh: Added and verify a NuttShell configuration
for the Mikroelektronika PIC32MX7 MMB board.
* arch/mips/pic32/pic32mx-ethernet.c: Fix logic that guesses PHY address;
the search loop missed the PHY address needed by the Mikroelektronika
PIC32MX7 MMB board.
* configs/pic32mx7mmb/nsh: Configuration now supports a network by default.
* configs/pic32mx7mmb/src: Add support for the MMC/SD slot on board
the Mikroelektronika PIC32MX7 MMB board (not working on initial check-in).
* arch/mips/src/pic32/pic32mx-spi.c: Add support for very low-level,
register access debug output.
* configs//pic32mx7mmb/include/board.h: Reduced peripheral clock to
4MHz to match other PIC32 configurations.
* configs/pic32mx7mmb/src/up_nsh.c: SD card needs to operate in SPI
mode 2.
* configs/pic32mx7mmb/nsh/defconfig: MMC/SD card support is now
enabled by default in the PIC32MX7 MMB board configuration.
* configs/pic32mx7mmb/nsh/defconfig: Verified the USB Mass Storage
Class (MSC) using MMC/SD card as the logical unit. Updated the default
PIC32MX7 MMB board configuration so that USB and the mass storage class
are enabled by default.
* drivers/lcd/mio283qt2.c and include/nuttx/lcd/mio283qt2.h: Add generic
support for the MIO283QT2 LCD.
* configs/pic32mx7mmb/src/up_mio283qt2.c: Add support for the MIO283QT2
LCD on the PIC32MX7 MMB board.
* configs/pic32mx7mmb/src/up_touchscreen.c: Add an ADC-based touchscreen
driver for the PIC32MX7 MMB board. Kind of works, but needs more
verification and tuning.
* arch/mips/src/common/up_idle.c: Strange but important fix. For some still-
unknown reason, interrupts are left in an unhealthy state in the IDLE
when the work queue is enabled. This is partially because some interrupt
related logic is not built in that case. Simply disabling then re-
enabling interrupts restores the proper state.
* graphics/nxglib/lcd/nxglib_filltrapezoid.c and fb/nxglib_filltrapezoid.c:
Fix an error when the trapezoid is only 1 line high. In this case, a
divide by zero error would occur. The fix is to draw the 1 line high
trapezoid as a run.
* drivers/usbdev/pl2303.c: Fixe a cut'n'paste error that snuck into
the PL2303 emulation driver several months back.
apps-6.19 2012-06-15 Gregory Nutt < gnutt@nuttx.org>
* apps/nshlib/nsh_usbdev.c: Add the capability to use an arbitrary USB
device as the console (not necessarily /dev/console). This is a useful
option because then you can still use the serial console to debug with.
* apps/nshlib/nsh_usbdev.c: User now has to press ENTER 3 times before
USB console will start. Otherwise, the USB console starts before there
is anyone at the other end to listen.
* apps/nshlib/nsh_usbdev.c and nsh_consolemain.c: Add support for the USB
capability when a USB console is used.
* apps/nshlib/nsh_fscmds.c: Add the 'mv' command
NxWidgets-1.2 2012-06-15 Gregory Nutt < gnutt@nuttx.org>
* NXWidgets::CCallback: callback arguement is now type CCallback and not
CWidgetControl; Added a method to redirect keyboard contacts to either
the widgets in the window (via CWidgetControl) or to an NxConsole (via
nxcon_kbdin()).
* NXWidgets::INxWindow, CBgWindow, CNxTkWindow, CNxToolbar, CNxWindow:
Now pass the CCallback intances as the callback argument instead of
the CWidgetControl instance. New method redirectNxConsole() will
support redirection of any window keyboard input to the NxConsole
(via CCallback).
* NxWM:CNxConsole: Configures the NxConsole window to redirection keyboard
input to the NxConsole; redirects standard input to the NxConsole
device driver.
* NxWM:CKeyboard: Add a new class that implements a keyboard listener
thread. This thread reads from /dev/console and injects the keyboard
input into NX. NX will determine which window is at the top of the
heirarchy and re-direct the keyboard input to only that top window.
This solves an important problem with, for example, running multiple
copies of the NxConsole: On the copy of the NxConsole at the top of
the heirarchy should get the keyboard input.
* UnitTests/nxwm/main.cxx: Now starts the keyboard thread if
CONFIG_NXWM_KEYBOARD is defined.
* NxWM::CTaskbar: After drawing the task bar, need to raise the
application window otherwise the taskbar will be on the top and
keyboard input will not be received by the top application.
* NxWM::CTaskbar: Bugfix... previous window should not be minimized
when a new window is started. It should stay in a maximized state
so that it will re-appear with the window above it is closed or
minimized.
* NxWM::CHexCalculator: Add a hexadecimal/decimal calculator
example.
* NXWidgets::CNxTkWindow: Back out height adjustment in the getSize()
method. The code was correct as it was before.
* NXWidgets::CButtonArray and NXWidgets::CGraphicsPort: There is
a kludge in there to handle the case where we cannot read the
background data because the LCD does not support read operations.
In that case, we just use the default background color. However,
that doesn't work either for the case where the background color
changes when the widget is selected. Then the background color
in the font is wrong. Fixed in CButtonArrary, but the problem
probably exists in other places as well.
* NxWM: Increase default spacing of icons on the Start Window.
* NxWM::CHexCalculator: Fix some non-standard calculator behavior
after = is pressed. Use upper case hex. Increase font size.
* nxwm/Makefile: Fix error that creapt in during some other
recent check-ins.

pascal-3.0 2011-05-15 Gregory Nutt < gnutt@nuttx.org>
2012-02-13 02:42:03 +01:00
* 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.
buildroot-1.10 2011-05-06 < gnutt@nuttx.org>
* Add patch submitted by Dimiter Georgiev to work around problems in building
GDB 6.8 with versions of Cygwin > 1.7.
* configs/i486-defconfig-4.3.3 - Builds an i486 cross development toolchain
using gcc 4.3.3. Why wouldyou want such a thing? On Linux, of course,
such a thing is not needed because you can use the installed GCC to build
i486 ELF binaries. But that will not work under Cygwin! The Cygwin
toolchain (and probably MinGW), build DOS MZ format executables (i.e.,
.exe files). That is probably not usable for most NuttX targets.
Instead, you should use this i486-elf-gcc to generate true ELF binaries
under Cygwin.
* Makefile - Alter copy arguments to avoid permissions problems when
copying NuttX header files.
* toolchain/nxflat/nxflat.mk and Makefile - Fix include paths.
* toolchain/gcc/3.3.6 - Added a patch to fixed compilation error on Ubuntu
9.10.
* toolchain/nxflat/Makefile - Correct static library link order.
* configs/arm920t-defconfig-4.3.3 - Enable support for NXFLAT tools.
* toolchain/binutils/2.21 and toolchain/gcc/4.5.2 - Add support for GCC
4.5.2 with binutils 2.21.
* configs/arm920t-eabi-defconfig-4.5.2 - Add a configuration to build a
GCC 4.5.2 EABI ARM toolchain for the ARM920t.
