This is a minor bugfix release.
|
||||
The primary reason for this release is to correct numerous build errors that have accumulated for the ZiLOG ZDS-II based targets.
|
||||
All ZDS-II targets now build correctly (but have not been re-tested).
|
||||
In addition to platform-specific build failures, release also adds the following features which were not tested as of the time of the release:
|
||||
This release adds no new OS features but does include support for two new architectures:
|
||||
<ul>
|
||||
<li>Board support fot the ZiLog ez80Acclaim! ez80f910200zco Development Kit,</li>
|
||||
<li>ZiLOG eZ80F91 EMAC driver</li>
|
||||
</ul>
|
||||
<li>
|
||||
<b>ez80Acclaim!</b>
|
||||
Basic support has been integrated and verified for the ez80f910200zcog-d board (eZ80F91-based).
|
||||
That basic support includes timer interrupts and serial console.
|
||||
Ongoing work includes an EMAC driver that should be integrated for the next release nuttx-0.4.2.
|
||||
</p>
|
||||
<p>
|
||||
eZ80Acclaim! support has been in the code base for some time, but has only just
|
||||
been integrated due to toolchain issues.
|
||||
</p>
|
||||
<li>
|
||||
<p>Renesas M16C/20</b>.
|
||||
Support for the Renesas SKP16C20 board has been included in the NuttX source tree.
|
||||
However, as was with the eZ80Acclaim!, testing and integration of that port is stalled due to toolchain issues.

* Added board support fot the ZiLog ez80Acclaim! ez80f910200zco Development Kit.
|
||||
* Fixed several compilation errors in fixed precision math library when built
|
||||
against toolchains that do not support 64-bit type 'long long'.
|
||||
* Fix errors in some function prototypes in dirent.h
|
||||
* Add eZ80F91 EMAC driver
|
||||
* Fix recvfrom() compilation error -- only noted under ZDS
|
||||
* Updated all ARM Make.def files to work with gcc 2.4.2 (However, there are
|
||||
still some build issues associated with that toolchain in use of arm-elf-objcopy
|
||||
-- see the TODO.txt list for details)
|
||||
* Fix problems with Z16F and eZ80 compilation introduced with recent changes.
|
||||
* M16C: Add support for the Renesas M16C MCU and the SKP16C26 StarterKit. However,
|
||||
the target cannot be built because the GNU m16c-elf-ld link fails with
|
||||
the following message:

No workaround is known at this time. This is a show stopper for M16C.

|
||||
context save and restore (Kevin Franzen).
