<b>Zilog eZ80Acclaim! Microncontroller</b>.
|
||||
This port uses the ZiLOG ez80f0910200kitg development kit, eZ80F091 part
|
||||
and the Zilog ZDS-II Windows command line tools.
|
||||
There are two eZ80Acclaim! ports:
|
||||
</p>
|
||||
<ul>
|
||||
<li>One uses the ZiLOG ez80f0910200kitg development kit, and
|
||||
<li>The other uses the ZiLOG ez80f0910200zcog-d development kit.
|
||||
</ul>
|
||||
<p>
|
||||
Both boards are based on the eZ80F091 part and both use the Zilog ZDS-II
|
||||
Windows command line tools.
|
||||
The development environment is Cygwin under WinXP.
|
||||

<b>STATUS:</b>
|
||||
Kevin Franzen has integrated and verified the ez80Acclaim! port and he has
|
||||
graciously provided the changes that he made. So I do not have first hand
|
||||
experience, but the ez80Acclaim! port should be functional.
|
||||
Kevin's changes were released in NuttX version 0.4.2.
|
||||
</p>
|
||||
<p>
|
||||
The EMAC driver has not yet been verified.
|
||||
Testing with the ZiLOG ez80f0910200kitg has been performed only on the on the ZDS-II simulator.
|
||||
However, support with the ZiLOG ez80f0910200zcog-d is complete.
|
||||
The first integrated version was released in NuttX version 0.4.2.
|
||||
As of this writing, that port provides basic board support with a serial console.
|
||||
An eZ80F09 EMAC driver has been developed, but not fully tested as of that releas.
