Thanks for testing.  That appears to be the same driver version that the guy in that other thread received from GSI (and which worked well on his Guruplug).  It makes me feel better about ordering one of these (but it also makes me wonder whether reliable Guruplug operation is also possible with this driver.)

Thanks for the reply.

Nice to hear from someone who's actually seen one.  Can you comment on a couple things?:

- It looks like the JTAG port has a uSD from factor.  How does this work?  Is it compatible with my guru JTAG box?  If so, how do I connect it?  Do I need a special cable?

You can use your Guruplug JTAG with a standard cable.

OK, I'll take your word for it.  But I'm still confused because the Dreamplug seems to have that uSD connector instead of the "standard" JTAG connector the Guruplug has.

- I'm still skeptical about whether the Guruplug reliability problems were ever fully understood (and whether they were all thermal related).  Have you done any testing under high I/O loads?  I'm particularly interested in running with wifi in client mode with lots of wifi traffic.  Is the wifi chip the same as the Guruplug and if so, are the supplied drivers the same version or newer?

Thanks!

James has been playing with it, not me, and I believe that we don't have any specific tests for high loads. What I can tell you is that:

  • it does seem to have basically the same rootfs as the Guruplug (including the wireless stuff), but it most certainly doesn't overheat. (The power adapter is separated from the main board, in a moulding that can be joined on to the main unit). There's also good heat dissipation from the heatsink.
  • As far as I understand it, the rootfs is not necessarily finalised.



I'm curious because of this thread (http://www.newit.co.uk/forum/index.php/topic,455.0.html) where a user claims that GSI sent him newer wifi driver source that solves the Guruplug instability issues when running as a wifi client.  I haven't had a chance to try it.

It depends upon the perspective, doesn't it?  Sure might seem like a rip-off to package the JTAG separately if you only plan to buy one unit.

It's a rip-off to package the JTAG separately if that's the only way to recover the device from brickville.

But, maybe if you've got something to sell to the public, you buy 100 Plugs and one JTAG port.  That way, you don't have to pay for the FDDI chips, etc. for all the sale units.

That's really poor strategic thinking. Field upgrades are impossible without the FDDI chip. Your customers can't just tether it to their PC and use their AmahiTunes Poseurware to synchronize, reflash or extend the plug's firmware, they would have to ship the whole unit back to you. Or you could send them an updated MicroSD and dare them to violate their warranty by opening the case and atempting to replace it themselves (unless you also intend to turn your back on your customers after their worthless 30-day warranty expires, just like GST did to you), or introduce your customers to GST's exciting new Disposable Computing concept where they simply throw away their old plug computer and buy a new one every year (or after every power supply burnout, whichever come first).

Has it occurred to you that even the cable of the GuruPlug JTAG board was coincidentally designed to break or wear out after just a few insertion/removal cycles? You'll need well more than just one of them to flash your hypothetical 100 Plugs, and since the cables aren't sold separately from the JTAG board they have an effective replacement cost of $30. You'd be better off buying 100 JTAG boards and shipping those in the box (along with a note of apology for the shoddy design, construction and workmanship of your products) to your customers.


GSI has given us many reasons to think that they are either incompetent or dishonest (or both), but I just don't think their reasons here are this devious.  Maybe I'm being naive, but I really don't think they left the JTAG out just to be able to sell us another box.  The volumes must be so low that I don't believe they are making enough money to justify the cost to design, manufacture and stock a separate item just to upsell.  Who knows.

Some things I've noticed about this:
- The mechanical interface for the JTAG board appears to be uSD.  So, even though the link goes to the Guruplug JTAG board, it's not clear that if you already have one it will work with this plug (at least not without a different cable).
- The DP (like the Guruplug JTAG) also has a UART port.  If this provides console access without a JTAG board, bootloader updates should at least be possible.

Uses the (optional) Guruplug JTAG board.

I couldnt see the same Ports as on the Guruplug (for JTAG/RS232)...
and my opinion would be that a "Dream Plug" has to be like the Sheevaplug - with a included JTAG/RS232-USB-Port

It's hard to tell what all the ports are, but I agree.  This thing certainly looks big enough to hold the JTAG logic, so the only reason to leave it out would be cost.
38  General Category / General Discussion / Re: DreamPlug on: January 25, 2011, 04:49:51 PM
Yeah, "JTAG tools" is what I meant by "hard to tell".  It's not clear (at least to me) if this means I won't need an external JTAG board to access the console.  Maybe, maybe not.
39  General Category / General Discussion / Re: DreamPlug on: January 25, 2011, 04:01:50 PM
Anyone know if the JTAG is built-in?  Hard to tell from that sheet.

Interesting.  Anybody ask about the price?
41  Linux Stuff / Kernel / Re: error in patchfiles for wifi client fix? on: January 12, 2011, 09:46:39 PM
It would be very cool if this new driver really solved the kernel crashes.  I haven't tried to build it yet.
42  General Category / General Discussion / Re: Is the window closing on Plug Computing? on: January 05, 2011, 07:54:03 PM
Even if it had been more successful, plug computing is still niche compared to phones and tablets.  And niche is not something Marvell is generally known to be interested in or good at.  I'd be interested in reading a report from someone at CES on how (or if) plug computing is positioned at the Marvell booth.
43  General Category / General Discussion / New Guruplug is noisy, but does it work? on: October 04, 2010, 06:13:24 PM
Noise notwithstanding, can anyone post their experience with the reliability of the fan-equipped version of the guruplug in an always-on application?  Please post your possible heat-generating usage (wifi, GE, high CPU utilisation, etc) and whether it now works reliably or not.

If your plug is bricked, take a look at http://wiki.slimdevices.com/index.php/SqueezePlug. It's a modified version of the Sheevaplug Installer that installs u-boot, installs Debian to either NAND or MMC  and provides some scripts to install and configure Squeezebox Server.

I had installed some Ubuntu updates (including a kernel) and forgot to reboot.  Once I booted into the new kernel, everything worked as expected.
