<b>STATUS:</b> <b>STATUS:</b>
The basic port is code complete. The basic port is code complete.
Two configurations are available: Two configurations are available:
An OS test configuration and a that support the NuttShell (NSH). (1) An OS test configuration and a (2) configuration that support the NuttShell (NSH).
The OS test configuration is fully functional and proves that we have a basically healthy NuttX port to the Mirtoo. The OS test configuration is fully functional and proves that we have a basically healthy NuttX port to the Mirtoo.
This includes support for the SST25 serial FLASH on board the module. The NSH configuration includes support for a serial console and for the SST25 serial FLASH and the PGA117 amplifier/multiplexer on board the module.
The NSH configuration is set up to use the NuttX wear-leveling FLASH file system (NXFFS).
The PGA117, however, is not yet fully integrated to support ADC sampling.
See the <a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a> for further information about NSH. See the <a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a> for further information about NSH.
There are some remaining issues to be resolved with the NSH configuration but, with any luck, the verified port should be available with the NuttX 6.20 release. The first verified port to the Mirtoo module was available with the NuttX 6.20 release.
