<a href="http://sourceforge.net/projects/nuttx/files/">SourceForge</a> website.
|

The change log associated with the release is available <a href="#currentrelease">here</a>.

</p>
|
||||
<p>
|
||||
The 6.0 release introduced a detach-able application environment to build applications outside of the NuttX source tree.
|
||||
The primary purpose of this release is to correct numerous build problems introduced by that architectural change:
|
||||
The 6.2 NuttX release includes several new features:
|
||||
</p>
|
||||
<ul>
|
||||
<li>
|
||||
In many newer environments, NuttX produced strange Makefile errors but built correctly in older environments.
|
||||
A fix provided by Rafael Noronha was incorporated and is reported to fix those build problems.
|
||||
NXFFS: The obvious new feature is NXFFS, the NuttX wear-leveling FLASH file system.
|
||||
This new file system is intended to be small for the MCU usage and has some limitations.
|
||||
No formal documentation of NXFFS yet exists.
|
||||
See the <a href="http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/nuttx/fs/nxffs/README.txt?view=log"><code>fs/nxffs/README.txt</code></a>
|
||||
file for more details.
|
||||
</li>
|
||||
<li>
|
||||
The <code>apps/</code> directory build system would not handle Windows-native toolchains due to obscure path formatting issues.
|
||||
Support for NXP LPCXpresso LPC1768 board on the Embedded Artists base board.
|
||||
The Code Red toolchain is supported under either Linux or Windows.
|
||||
Verifed configurations include DHCPD, the NuttShell (NSH), NuttX graphis (NX), the NuttX OS test, THTTPD, and USB mass storage device.
|
||||
</li>
|
||||
<li>
|
||||
And other problems as detailed in the change log.
|
||||
Support for the Univision UG-9664HSWAG01 OLED with Solomon Systech SD1305 LCD controller.
|
||||
</li>
|
||||
<li>
|
||||
A new RAM MTD driver with FLASH simulation capability.
|
||||
</li>
|
||||
<li>
|
||||
A <code>version.h</code> file is now automatically generated so that C code can now be version-aware.
|
||||
</li>
|
||||
</ul>
|
||||
|
||||
<p>
|
||||
Many additional changes were made in the 6.1 release for another major architectural change:
|
||||
NuttX will now build as a seperately linked micro-kernel.
|
||||
In this build option the RTOS builds as a kernel, applications build separtate and interface with kernel via system calls.
|
||||
Applications run in user mode and kernel logic users in kernel-mode.
|
||||
This provides a secure environment for NuttX.
|
||||
This feature is fully coded in NuttX-6.1, but has not been tested due to higher priority tasks that have arisen.
|
||||
</p>
|
||||
<p>
|
||||
Related to this change, support for the Cortex-M3 memory protection unit (MPU) has been integrated with the NuttX kernel build to provide an even higher level of security.
|
||||
</p>
|
||||
<p><small>
|
||||
NOTE: This kernel build is an option; the default build configuration is still the standard, flat, unsecured RTOS as in previous releases.
|
||||
</small></p>
|
||||
<p>
|
||||
Additional new features in this release:
|
||||
</p>
|
||||
<ul>
|
||||
<li>
|
||||
Support for LPC17xx GPIO interrupts (with much support from Decio Renno).
|
||||
</li>
|
||||
<li>
|
||||
Basic timer support for STM32 (Contributed by Uros Platise)
|
||||
</li>
|
||||
<li>
|
||||
A binfs file system.
|
||||
This is a tiny psuedo file system that lets named appliations to be viewed and accessed in NSH under the <code>/bin</code> directory.
|
||||
</li>
|
||||
<li>
|
||||
An I2C-based driver for the LIS331DL MEMS motion sensor (Contributed by Uros Platise).
|
||||
</li>
|
||||
<li>
|
||||
A board configuration for the Embedded Artists LPCXpresso LPC1768 board.
|
||||
</li>
|
||||
<li>
|
||||
The <code>user_initialize()</code> interface has been removed.
|
||||
</li>
|
||||
</ul>
|
||||
|
||||
<p>
|
||||
And several bugfix are included.
|
||||
This includes chagnes associated with SD drivers, openddir(), signed 8-bit types (<code>int8_t</code>), and USB serial device. See the ChangeLog for details.
|
||||
In addition to these new feature, several important bugfixes are included in this release correcting problems with
|
||||
<code>dup2()</code>, LPC17xx GPIO interrupts, LPC17xx UART2/3, the FAT file system, build issues, and <code>strrch()</code>.

nuttx-6.1 2011-04-10 Gregory Nutt <spudmonkey@racsa.co.cr>
|
||||
|
||||
* arch/arm/include/lpc17xx/irq.h and arch/arm/src/lpc17xx/lpc17_gpio*.c:
|
||||
Fix several bugs in the GPIO interrupt logic. Submited by
|
||||
Decio Renno.
|
||||
* Initialization for the CONFIG_APPS_DIR is now supported during the
|
||||
earlier, 'context' build phase.
|
||||
* arch/arm/src/lpc17_gpioint.c: Finish coding of the LPC17xx GPIO
|
||||
interrupt logic.
|
||||
* net/netdev_unregister.c: Add capability to un-register a network
|
||||
device.
|
||||
* drivers/mmcsd/mmcsd_sdio.c: extra effort to correctly handle cases
|
||||
without the SDcard (but one issue still exists in STM32)
|
||||
* arch/arm/src/stm32/stm32_tim.*: Added basic timer support TIM1..TIM8
|
||||
with output PWMs and interrupt logic
|
||||
* config/vsn/src: added basic support for Sensor Interface (GPIO and
|
||||
PWM Power Output, and the sif utility program)
|
||||
* fs/: Reorgnize header so that file systems can be built outside
|
||||
of the nuttx source tree
|
||||
* apps/namedapp/binfs.c: Create a tiny filesystem that can be used
|
||||
to show the internal named apps under /bin.
|
||||
* fs/fs_opendir.c: Correct an error that occurs when a file system is
|
||||
mounted in the root directory. This was discovered while mounting
|
||||
the named app's /bin directory.
|
||||
* lib/: Move all source files into a subdirectory of lib/ named after
|
||||
the header file in which the library function is prototyped.
|
||||
* sched/ and lib/pthread/: Move pthread attribute-related interfaces
|
||||
from sched/ to lib/pthread where they more appropriately belong.
|
||||
* sched/ and lib/semaphore/: Move some semaphore-related interfaces
|
||||
from sched/ to lib/pthread where they more appropriately belong.
|
||||
* syscall/: The beginnings of an optional syscall kernel interface.
|
||||
* tools/mksyscall.c: Add a tool that will auto-generate syscall proxies
|
||||
and stubs from a comma-separated-value (CSV) data file.
|
||||
* arch/arm/src/cortexm3/mpu.h: Add a header file describing the Cortex-M3
|
||||
MPU registers.
|
||||
* Numerous modifications to the build system. Various people have reported
|
||||
build problems since the re-organization and release of NuttX-6.0. I am
|
||||
unable to replicate the build problems in my environment, but the changes
|
||||
have be incorporated in hope of correcting the build issues in other
|
||||
environments.
|
||||
* drivers/i2c/st_lis331dl.c: I2C-based driver for the LIS331DL MEMS
|
||||
motion sensor. Contributed by Uros Platise.
|
||||
* Makefile: The NuttX build system will now supported building NuttX as two
|
||||
separately linked images: (1) a kernel-mode RTOS image, and (2) a user-
|
||||
mode application image that communicates to the RTOS kernel via system
|
||||
calls. A lot more still must be done.
|
||||
* user_initialize(): Eliminated the user_initialize() initialization hook.
|
||||
It is difficult to maintain and redundant: Board level initialization
|
||||
an up_initialize() provide the same kind of capability.
|
||||
* arch/*/include/*/type.h: On some compilers, char defaults as unsigned.
|
||||
Explicitly add signed to integer types if signed is what is required.
|
||||
* arch/*: For all architectures -- Global register state save structure
|
||||
(usually called current_regs) should be marked volatile; Added general
|
||||
capability to support nested interrupts (not fully realized for all
|
||||
architectures).
|
||||
* sched/task_create.c: Add support for starting kernel-mode thread.
|
||||
* drivers/usbdev/usbdev_serial.c: Fix reported by Sheref Younan. USB
|
||||
was being reset after serial driver was closed. As a result, you could
|
||||
no reopen the serial driver.
|
||||
* configs/lpcxpresso-lpc1768: Add a board configuration for the Embedded
|
||||
Artists LPCXpresso LPC1768 board.

nuttx-6.2
|
||||
^^^^^^^^^
|
||||
|
||||
The 69th release of NuttX, Version 6.2, was made on May 6, 2011 and is
|
||||
available for download from the SourceForge website. The 6.2 release
|
||||
includes several new features:
|
||||
|
||||
* NXFFS: The obvious new feature is NXFFS, the NuttX wear-leveling
|
||||
FLASH file system. This new file system is intended to be
|
||||
small for the MCU usage and has some limitations. No formal
|
||||
documentation of NXFFS yet exists. See the fs/nxffs/README.txt
|
||||
file for details (see
|
||||
http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/nuttx/fs/nxffs/README.txt?view=log)
|
||||
* Support for NXP LPCXpresso LPC1768 board on the Embedded
|
||||
Artists base board. The Code Red toolchain is supported under
|
||||
either Linux or Windows. Verifed configurations include dhcpd,
|
||||
nsh, nx, ostest, thttpd, and usbstorage.
|
||||
* Support for the Univision UG-9664HSWAG01 OLED with Solomon
|
||||
Systech SD1305 LCD controller.
|
||||
* A new RAM MTD driver with FLASH simulation capability.
|
||||
* A version.h file is now automatically generated so that C code
|
||||
can now be version-aware.
|
||||
|
||||
In addition to these new feature, several important bugfixes are included
|
||||
in this release correcting problems with dup2(), LPC17xx GPIO interrupts,
|
||||
LPC17xx UART2/3, the FAT file system, build issues, and strrch(). See the
|
||||
ChangeLog for more details.
