A port is in progress from the DTX1-4000L &quot;Mirtoo&quot; module from <a href="http://www.dimitech.com/" >Dimitech</a>.
This module uses MicroChip PIC32MX250F128D and the Dimitech DTX1-4000L EV-kit1 V2.
See the <a href="http://www.dimitech.com/">Dimitech</a> website for further information.

<ul>
<p>
<b>STATUS:</b>
The basic port is code complete but still not fully verified.
With any luck, the verified port should be available with the NuttX 6.20 release.

So far, I have no clue why this is failing.
UPDATE: This bug was recorded using the PIC32 Ethernet
Starter kit with a RAM disk (that board has no SD card slot).
Howevever, using the USB mass storage device with the
Mikroelektronika using a real SD card, there is no such
problem -- the mass storage device is quite stable.
problem -- the mass storage device seems quite stable.
UPDATE: Hmmm.. retesting with the Mikroelectronka board
shows problems again. I think that there are some subtle
timing bugs whose effects can very from innocuous to severe.
Status: Open
Priority: Originally, High BUT reduced to very Low based on the
UPDATED comments.
