NuttX-0.3.7
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This is the 19th release of NuttX. This release includes the
|
||
|
|
preliminary port of NuttX to the ZiLOG z16f 16-bit microcontroller.
|
||
|
|
This port was verified using the ZiLOG z16f2800100zcog Development
|
||
|
|
and the ZiLOG ZDS-II toolchain. See http://www.zilog.com for
|
||
|
|
further information.
|
||
|
|
|
||
|
|
I emphasize that this is a preliminary release of the z16f port and
|
||
|
|
is only alpha or, perhaps, pre-alpha quality as of this writing.
|
||
|
|
There are a list of known issues in the TODO file in the root of
|
||
|
|
the NuttX directory. The overall quality of NuttX (excluding the
|
||
|
|
z16f port) continues to improve beyond the late beta level.
|
||
|
|
|
||
|
|
The z16f port required numerous changes to NuttX to handle:
|
||
|
|
|
||
|
|
* NEAR and FAR addressing, and
|
||
|
|
* Use of a Windows native toolchain in a Cygwin build environment.
|
||
|
|
|
||
|
|
In addition to the z16f port, at least one very critical bug was
|
||
|
|
found and corrected in NuttX: The thread-specific errno value of one
|
||
|
|
task was being randomly trashed when a different thread exited.
|
||
|
|
|
||
|
|
This release were verified on the ZiLOG z16f2800100zcog, Neuros OSD
|
||
|
|
(ARM9), and the simulation platforms. As usual, any feedback about bugs
|
||
|
|
or suggestions for improvement would be greatly appreciated.
