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 https://nuttx.apache.org/docs/latest/components/paging.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 configuration
|
||
|
|
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.
