1  General Category / General Discussion / Re: Warning: GlobalScale are Thieves on: June 09, 2010, 05:22:58 PM
Does anyone from GlobalScale read these forums or answer questions on them?
No, they don't, or at least they don't post.

It has now been two months since I ordered a GuruPlug Server Plus and there has been no word from them. GlobalScale were prompt to take payment, but have not been prompt about anything else.

Reading around on the forums it seems the GuruPlugs have some hardware problems (e.g. overheating circuitboards, failing power supplies) and some software problems (e.g. setting ethernet to 1Gbps crashes the computer). So now I find myself in the position of waiting longer than expected for a product that may be broken, having paid months ago.

Does anyone have an informed answer to these questions:

1. Do GlobalScale accept that there are serious problems with some or all of the GuruPlugs that have been shipped out?
I called and spoke with them; they're making a replacement board that I was told will ship in early June.
Quote
2. Are the shipping delays at all related to the hardware and software problems - that is, are GlobalScale doing anything to fix these problems before shipping new GuruPlugs out?
They supposedly have a replacement board that will be out soon.
Quote
3. Why does the website warn of a 4-week shipping delay when delays seem to be at least twice that?
They're terrible at communication.  It's said that since before the first shipments came.
Quote
4. Can GlobalScale offer any assurance that, when we finally receive our GuruPlugs, they will work?
Probably not, but we can hope, right?
Quote
5. What support do GlobalScale promise to customers whose GuruPlugs have he problems mentioned above?
They had me RMA my Plus last week; it's currently on its way to them (at their cost).

It would be great if some official representative of GlobalScale could get on this thread and answer some of our questions.

The only way you're going to get any official word would be phone.  Their PBX is primitive, but pressing '0' got me to a real person who could process an RMA.

I'd just like to link to this thread: How to Add and Control GPIO's of the Sheevaplug, since it seems that kernel modules must be recompiled in order to achieve GPIO.

Cheers!

You would have to build the GPIO driver for the uC (kw_gpio, I believe) and load it.  Then use the "files" in /sys/class/gpio to export and control the pins.

Alternatively, you could write something that uses /proc/kcore to do direct memory access to the peripheral registers, but that's dangerous.

Yes, they've made some pretty bad choices and ended up with a device that's almost good enough for a lot of things, but perfect for none.  Maybe you can find a surface mount header that's the same pitch as the unpopulated pads?  What pitch is it?  That would at least give you the option of removing swapping things out without having to desolder and risk ruining the board if you ever need to change anything.  Or maybe use the u-snap interface's pins as a GPIO I2C master? Or attach a SPI to I2C driver there?

Yes, that pretty much sums it up.  I would have loved if they would have brought I2C to the "reserved" pins on the u-snap  header.  You could still implement a GPIO I2C driver at that header, but you lose the advantages of the hardware driver.  I haven't cracked mine open yet (I'm waiting until the power supply issues are fixed so I don't void my warranty prematurely) but I intend to attach wires (or maybe a header) to the unpopulated pads on U15.

I thought about sandwiching a third board between the two, but trying to align everything properly (though it doesn't have to be one board, it could be two with the male and female headers on each directly in line, thus avoiding the alignment issues) and the resulting abomination no longer fitting in the case deterred me.  If I can figure out a better case and can find the appropriate headers, this might be the cleanest solution overall.  I might populate the internal uSD slot too while I'm in there.  (Again, if I can find the proper part.)

I can get eth0 or eth1 (I haven't tried both at the same time) to come up at 100 meg, but cycle link up/link down if I try to bring them up at 1 gig.

Is it possible to lock the speed to 100 in the plug? I am not able to change speed of the switch right now...

/Jimmy

You should be able to with mii-tool.  Something like `mii-tool -F 100baseTx-FD eth0` should work.  If that doesn't, and you have what you need, you can make an ethernet cable with only the first two pair so there's no way it can negotiate to 1 gig.  Also, sometimes mine negotiates to 100 meg on its own after a few up/down cycles at 1 gig.

I hope these problems get fixed (whether by GST or someone here I don't much care) and someone posts a good, working uboot, kernel, and RFS that works with all the plug has to offer.  I hate not being able to boot from usb or esata, but I'm not familiar enough with the architecture to build my own system yet.

I'm pretty sure Globalscale lied about shipping my plug in April.  Until this afternoon my order page said it shipped April 30 with a tracking number pending.  Today, I got an email with a tracking number (that FedEx knows nothing about) and my order is now showing it shipped today.  Does anyone else think they lied to appear to meet their shipping deadline?

I looked there first (along with monoprice and cables2go) and the shortest I've been able to find is 45cm.

Any more on this?  I ordered the Plus version on Feb 11 and haven't heard anything since then except the delay note on Apr 1.
10  General Category / General Discussion / Re: Guruplug Server Plus built-in serial port? on: May 03, 2010, 08:58:28 AM
There are lots of options for a USB to 3.3v Async serial.  http://www.sparkfun.com/commerce/product_info.php?products_id=718 for one, though there are MANY others.
11  General Category / General Discussion / Re: Guruplug Server Plus built-in serial port? on: April 30, 2010, 07:20:11 AM
If you are adding the JTag device to allow an application to use the RS232 port (not for debugging purposes), you could use a USB-2-Serial converter in the standard USB port instead.  It might be cheaper/easier. Smiley

It isn't easier or cheaper than using what's already there, and doesn't take one of the two available USB ports.  Interfacing with USB would require additional parts, when interfacing with the 3.3v async lines wouldn't if what I'm attaching already uses 3.3v signaling.

Aah, makes sense.  All I have to work with are the pictures accompanying the FCC certification.  I didn't know anybody outside GST had a GuruPlug.
13  General Category / General Discussion / Re: GuruPlug - Internal microSD slot on: April 29, 2010, 04:37:04 PM
Is it not just held together with screws in the four holes in the back?
14  General Category / General Discussion / Re: GuruPlug - Internal microSD slot on: April 29, 2010, 04:16:53 PM
I don't think anyone outside of Globalscale knows for sure.  We don't even know if it's populated on the Plus version, just assumptions based on the FCC certification pictures.

Actually, for a lot of purposes this is better.  You can interface with anything that speaks async. serial with just a voltage difference instead of only being able to interface with USB masters.
