NuttX-5.5
|
||
|
|
---------
|
||
|
|
|
||
|
|
This is the 52nd release of NuttX. This release includes one new
|
||
|
|
port, some new drivers and some important bugfixes:
|
||
|
|
|
||
|
|
* NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation
|
||
|
|
Kit. At present, that port includes an OS test configuration
|
||
|
|
and a NuttShell (NSH) configuration with Telnet support.
|
||
|
|
|
||
|
|
MMC/SD and Networking support are provided but not thoroughly
|
||
|
|
verified in this release: Current development efforts are focused
|
||
|
|
on porting the NuttX window system (NX) to work with the
|
||
|
|
Evaluation Kits OLED display.
|
||
|
|
|
||
|
|
* A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet
|
||
|
|
chip is available in the source tree (but has not yet been fully
|
||
|
|
verified because I haven't properly connected it to hardware
|
||
|
|
yet).
|
||
|
|
|
||
|
|
* The Olimex STR-P711 NuttX port was extended to support the
|
||
|
|
ENC28J60 and some new networking configurations were added.
|
||
|
|
The ENC28J60 has not been tested on the STR-P711, however,
|
||
|
|
because of hardware issues (I don't think the USB powered board
|
||
|
|
provides enough power for the ENC28J60 and I don't have the
|
||
|
|
right wall wart yet).
|
||
|
|
|
||
|
|
Along the way, external interrupt support (XTI) was added to
|
||
|
|
the STMicro STR-P711 port and some important bugs were fixed
|
||
|
|
in the STR-P711 SPI driver.
|
||
|
|
|
||
|
|
* Added (optional) floating point support for printf().

|
||
|
|
|
||
|
|
* Corrected an important UDP reference counting error. It was
|
||
|
|
not a serious error, but it trigger an assertion was IS a serious
|
||
|
|
error.
