1  General Category / General Discussion / Plug alternative: nVidia's Tegra-2 on: January 26, 2011, 12:21:20 PM
Noting that nVidia's Tegra-2 certainly has demanding power & heat requirements... like all the various "plug" computers discussed on this forum, it was a delight to finally see Tegra-2 to make it into the "plug" form factor race:


We're talking dual-core ARM A9 @ 1GHz plus fairly impressive video thrown in for good measure in a little 3W industrial design :-) From my FitPC-1 days, this also means an external power supply... so, perhaps not technically a "plug" form factor to some/many on this forum.

It remains to be seen what price this little gem comes in at. Rumors are all over the place, but I suspect that the various Intel PineTrail ATOM & AMD Fusion offerings in this same space will present a firm "upper bound" on the price point of Tegra-2 designs.

The bigger risk of slowed (halted?) progress on so-called plug computers is, IMHO, to be overtaken by those very much mainstream SoC-based smartphone/tablet platforms.

Indeed, the folly of trying to graft a display onto the "plug" (as many pitched during Marvell's "Plug Event" last year) has me completely baffled. Were I to need an ARM-based SoC platform that supported display logic, there are a variety of alternatives out there with much more motivation to be low power, reliable, cheap,... In fact, a plug-sized nVidia Tegra-2 solution with the display simply not exposed would seem to be plenty of competition for our current options. I might be able to find a very good use for the parallel processing power of that GPU :-).

In short, I feel Marvell can only hope the "plug" to succeed at a $10 price point, not $50...and actually fit in something the size of an actual plug. What we have today is the size of a "wall wart" of course.

How about just getting one of the many external USB 3.5" drives... They're cheaper, more reliable, and usually come with their own power supply.

How about a Seagate DockStar @ approx. $30?

Given your terse description, it appears you haven't updated the bootloader.  So can you not boot an alternative OS from somewhere else and, using that, replace the kernel and rootfs on your Guruplug's internal flash?

Received the following PM from "endisorc" (listed as a "Newbie")
  I am interested in your nick-name
  Greetings companion edmc !
  We are interested in your name
  We study non-standard nicknames
  Look about your names http://mimosa.org.ua/edmc

Following the link immediately attempts to download something (I discarded it immediately so I do not know what crap was attempting to infect my PC).

Suggest you do the same  Tongue

Check out the Wikipedia article here.  Scroll down to the heading "Hub software".  It lists a number of "hub servers".  There seem to be several options there...
8  General Category / General Discussion / Re: dc++ server on: June 18, 2009, 11:01:55 PM
So I went to google.com and typed into the search field "dc plus plus" (without the double-quotes)  Grin

It returned 10 pages of results of which the first two pages were true hits (among them a reference to the SourceForge project site here.

While the source is available, it would appear to have some Windows-specific dependencies so I'm not sure if you could make a go of dc++ on the SheevaPlug.
9  General Category / General Discussion / Re: Sheevaplug installer - alpha-6 release - Testers needed on: June 16, 2009, 09:06:30 AM
Why won't the Sheeva environment execute the script?

Think of it this way... the Installer is being asked to re-write all (or some) of the flash that the Sheeva OS is currently using to present an execution environment.  The JTAG interface used by the Installer allows an external device (via this USB/Serial-to-JTAG connection) to write to the Flash without any help from software running on the SheevaPlug itself.  This would be mandatory if, say, the OS on the SheevaPlug got so corrupted it wouldn't boot.
10  General Category / General Discussion / Re: Windows version for the Sheevaplug installer on: May 30, 2009, 12:09:28 PM
A fact that more than 130 people viewed this poll, and none has voted.

The challenge of writing good polling questions is very high.  I submit to you that there are a wide array of ways one could interpret your poll question.  Do we want to use a Windows version?  Do we want a Windows version available so that the space of would-be SheevaPlug developers could broaden?  Very ambiguous at best.

Indeed, as I'm sure you well know, there is a whole science of phrasing polling questions in a way to garner a desired result :-)...

What I find much more helpful is to understand the various things that could be done and prioritize them.

If, instead, you were to craft your "poll" to list the various U-Boot enhancements being considered, estimate their development time, and allow folks like us forum-its to prioritize the list to our own preferences, that would be both clearer what was being asked and, I dare say, more helpful to you.

How about this thread over in the "General" forum  Wink
12  Hardware and U-Boot firmware / Hardware / Re: SheevaPlug v2 - Hardware Requests on: May 01, 2009, 11:49:58 AM
To get this thread back on topic :-)

I'd like to see an internal-encased SD Slot.  Sure, the externally-accessible SD Slot
has it's uses... but some may want to "secure" the SD Card in the unit entirely.
13  Linux Stuff / General Linux questions / Re: Date-Time on: April 28, 2009, 12:43:53 PM
I just noticed that in the stock rootfs, the following lines are in rc.local:

date 012618002009
hwclock -w


As the Wiki suggests, comment out those lines :-)
14  Hardware and U-Boot firmware / Hardware / Re: Did my SheevaPlug arrive broken? on: April 17, 2009, 12:49:57 AM
Just wanted to close this thread out proper.  Indeed, my SheevaPlug was bad - and I'm suspecting
others SheevaPlugs that fail are due to similar defects.  Mine would only light up one of the LEDs,
never the 2nd one.

Just received my replacement from GlobalScale and it powered up perfectly.  Installing the drivers
in Vista went perfect... only slightly different than the WinXP process documented.

And for any that are interested, here is the output from USBView for my new/functioning Plug:

Equivalent to the report in moshiach's reply earlier...

This is from a working plug attached to a linux computer.
Vendor Id: 9e88
Product Id: 9e8f
The fact that you aren't seeing a product ID or vendor ID  pretty much points to a likely dead plug.   Unless you just don't have the windows usb serial drivers installed properly.

Thanks for posting... and the advice.  Re the "usb serial drivers", it's actually a Windows/Vista thing that it needs to see a VendorID/ProductID to know which driver to install.  Since my SheevaPlug isn't reporting correctly, Windows/Vista doesn't know which driver to select to talk to it.

GlobalScale is shipping me a new device & I'll return this one.  I guess its comforting to think that nobody else's arrived dead.
