<b>STATUS</b>.
At this time there are no board support packages for the <i>Giant Gecko</i> in the NuttX source tree (there are ports to proprietary <i>Giant Gecko</i> hardware, howevever).
</p>
</ul>
As of this writing, the basic board support is available for the <i>Giant Gecko</i> in the NuttX source tree.
A basic configuration is available for the NuttShell (NSH).
Testing is on hold, however, pending the arrival of hardware.
