NuttX-6.20
|
||
|
|
----------
|
||
|
|
|
||
|
|
The 87th release of NuttX, Version 6.20, was made on July 12, 2012,
|
||
|
|
and is available for download from the SourceForge website. Note
|
||
|
|
that release consists of two tarballs: nuttx-6.20.tar.gz and
|
||
|
|
apps-6.20.tar.gz. Both may be needed (see the top-level nuttx/README.txt
|
||
|
|
file for build information).
|
||
|
|
|
||
|
|
This release corresponds with SVN release number: r4937
|
||
|
|
|
||
|
|
Additional new features and extended functionality:
|
||
|
|
|
||
|
|
* Power Management: An evolving power management example is being
|
||
|
|
created by Diego Sanchez. This effort currently involves on the
|
||
|
|
STM32 F1 but clearly demonstrates the NuttX power management
|
||
|
|
system which will automatically drive the system to lower power
|
||
|
|
usage states due to lack of use.
|
||
|
|
|
||
|
|
* Drivers: Added a driver for the SST 25 SPI-based FLASH parts.
|
||
|
|
|
||
|
|
* PIC32: Added support for the PIC32MX1 and PIC32MX2 families.
|
||
|
|
Added support for the microchipOpen and Pinguino toolchains.
|
||
|
|
|
||
|
|
* NXP LPC43XX: Added support for the entire LPC43xx family
|
||
|
|
|
||
|
|
* PIC32 boards: Added support for the DTX1-4000L "Mirtoo" module
|
||
|
|
from http://www.dimitech.com/ (PIC32MX2).
|
||
|
|
|
||
|
|
* NXP LPC43XX Boards: Added support for NGX LPC4330-Xplorer board.
|
||
|
|
|
||
|
|
* NXP LPC17XX Boards: Added support for Micromint Lincoln60 board
|
||
|
|
(LPC1769).
|
||
|
|
|
||
|
|
* LM3S Boards: Add a configuration to support the TI/Stellaris
|
||
|
|
EKK-LM3S3B96 development board. Contributed by Jose Pablo Rojas V.
|
||
|
|
|
||
|
|
* Library: NuttX now supports platform-specific stdarg.h header
|
||
|
|
files.
|
||
|
|
|
||
|
|
Work in progress. This release includes some partially completed
|
||
|
|
work that is still not ready for prime time.
|
||
|
|
|
||
|
|
* Automated Configuration. Automated configuration based on the
|
||
|
|
kconfig-frontends tool is being incorporated into the build
|
||
|
|
system. The configuration is still not complete enough for
|
||
|
|
general use in this release.
|
||
|
|
|
||
|
|
* STM32 Drivers. Added files that will (eventually) hold an STM32
|
||
|
|
OTG FS host driver. This is still a work in progress.
|
||
|
|
|
||
|
|
Bugfixes (see the change log for details) :
|
||
|
|
|
||
|
|
* PIC32: GPIO output configuration (critical bug)
|
||
|
|
* STM32: Typos in pin mapping files.
|
||
|
|
* LM3S: Fixed an optimization related but that caused slow start-up
|
||
|
|
times if optimization was disabled.
|
||
|
|
* Library: Fixed signed extension but in all limit.h files
|
||
|
|
(reported by Lorenz Meier). inet_ntoa compilation failure
|
||
|
|
on Z80.
|
||
|

As well as other, less critical bugs (see the ChangeLog for details)
