Plugcomputer.org Documentation Resource --- Update for new revision?

[superpat]

Hi,

For some time now, (since around July), GlobalScale have been shipping a new single board SheevaPlug, Version 1.3. This revision is based on ONE module, instead of the two in the original shipped product.  None of the hardware documentation on this website has been  upgraded to include the current shipping revision, nor has the CDRom supplied with the Dev Kit.

There are significant differences to the product, (one example is the change in the FTDI recognition resulting in problems connecting serial terminals). Other members of this forum have posted photographs of the intriguing additional connectors available on the module. Another problem is knowing what has happened to GPIO and other signals that were available on the FPC cable between the two boards.

I have made repeated requests for the new schematic and layout to be made available,  via PM, to  Rabeeth  whom I believe is a Marvell employee, and by several emails to GlobalScale sales and support.   I have not had any reply, not even the courtesy of an acknowledgement to my requests. It is as though my emails are being sucked into a black hole!

My understanding of the SheevaPlug dev kit was that it was an open product, which to me was confirmed by the original complete set of mechanical, electrical drawings and the BOM being made available.

Since there is apparently no movement to publish the current revision documentation,  I have come to the conclusion that the Sheeva Plug Dev Kit is only an open software design and the hardware design is now confidential.

Please can someone either in GlobalScale or Marvell tell me whether this is so, and if the hardware design is still open,  please tell us why the current hardware documentation, i.e. layout, schematic and BOM, are not being made available.

thank you

regards

Patrick

 Hi Rabeeh

Many, many thanks for the schematic drawing.

I have had a quick look,  the esata  details are very interesting!  If I am reading it correctly, lots of fine rework soldering is about to occur, I need to dig out my Aoyue soldering station.

I am still puzzling over the GPIO  signals, where they have gone, I need to do a compare between the old and current revs!
The schematic was originally on A3 sheets, and my viewer is a bit unstable trying to view at 200%, keeps jumping from sheet to sheet.  I need to find a better way to look at these sheets.

thanks again

Patrick
