nuttx-5.9
^^^^^^^^^
This is the 56th release of NuttX. This release is difficult to categorize;
NuttX-5.9 was really released because there were too many changes accumulating
in CVS -- a few important, some unfinished implementations, and a couple of
important bugfixes.
* By far biggest change in this release is the complete implementation
of on-demand paging support. This feature will allow you to execute large
programs on a mass storage device (such as SPI FLASH) in a small RAM.
All of the core on-demand paging logic was completed (see
http://www.nuttx.org/NuttXDemandPaging.html) and support was implemented
for the ARM-9 family. A test configuration is in place for the NXP
LPC3131. It has been verified that this new logic does not interfere
with normal fixed-page ARM9 operation, but otherwise this new on-demand
paging feature is untested.
* Add support for the CodeSourcery toolchain to the Olimex-lpc2378 port
and for the Neuros OSD port.
* The Neuros OSD port has been updated to work with the production v1.0
OSD (previously it only worked with the development board).
* And some miscellaneous feature enhancements as detailed in the ChangeLog.
This includes several important bugfixes:
* NXP LPC17xx - Fixed a critical bug in the GPIO configuratino logic:
When attempting to set no pull-up or pull-down (floating), it would,
instead, select pull-down.
* TI/Luminary LM3Sxxxx - Fixed (1) a logic error in an address table
lookup, (2) GPIO port encoding the limited support to only 8 GPIO
ports.
* Corrected the lease time in the DHCPC implementation: It was not in
host byte order.
* And several other less important bugs as documented in the ChangeLog:
Warnings, cornercase compilation problems, etc.
