NuttX-0.3.19
|
|
------------
|
|
|
|
This is the 31st release of NuttX. This release includes the
|
|
following new feature:
|
|
|
|
* Add poll() and select() APIs that may be used to monitor for
|
|
data availability on character devices or TCP/IP sockets.
|
|
* Implemented support TCP/IP connection backlog. This allows
|
|
select() to wake-up on new connections to a listener socket.
|
|
* Added definition of a framebuffer driver and implement framebuffer
|
|
drivers for the simulated platform and the TI DM320 (untested
|
|
as of the initial check-in).
|
|
* Partially developed a graphics framework based on the framebuffer
|
|
drivers, however, this will not be ready for use for a few more
|
|
releases. Currently this includes only a few color conversion
|
|
routines and some rasterizing functions. A tiny windowing system
|
|
is under development but not ready for check-in yet.
|
|
* Added support for fixed precision math.
|
|
* Added support for outgoing multicast packets.
|
|
|
|
Several bugs were fixed, the most important of which are:
|
|
|
|
* Fixed an important bug in the TCP/IP buffering logic. When
|
|
TCP/IP read-ahead is enabled and not recv() is in-place when a
|
|
TCP/IP packet is received, the packet is placed into a read-ahead
|
|
buffer. However, the old contents of the read-ahead buffer
|
|
were not being cleared and old data would contaminate the newly
|
|
received buffer.
|
|
|
|
* Changed the behavior of the serial driver read. It now returns
|
|
data as it is available rather than waiting for the full requested
|
|
read size. This makes functions like fgetc() work much more
|
|
smoothly.
|
|
|
|
These changes were verified only on the Neuros OSD (ARM9) using a
|
|
Linux development environment. Please report any errors to me.
