106  Hardware and U-Boot firmware / Hardware / Re: type of microSD for guruplug? on: May 19, 2010, 02:29:31 AM
maybe you have some howto for this?  Smiley

I think "Yes, he has :-)"
Take a look at http://plugcomputer.org/plugforum/index.php?topic=1642.msg10106#msg10106

My serial port issue was I removed Flow Control - that solved the not being able to transmit from serial to the plug
I can confirm the ethernet port work via 100mb switch and not 1000mb switch.

Yes, its 115.200 Baud 8N1 noFlow-Control like on the Sheevaplug.
I also can confirm the Gigabit-Switch-Problem after getting yesterday
a DLINK igabit-Nway-Switch my Guru+ did also reboot...back to my old
100MBit Switch the Ethetnet-Port does work like before.
For me it seems to be a driver-issue not a power-supply problem...but
Gigabit uses more lines inside the CAT5-Ethernet cable than 100MBit does

I got mine also today but without advertised free jtag module, which makes it quite useless because the unit doesn't even boot up a mini linux without jtag fiddling. At least it does not ask for an IP connected to my LAN. Am I asking for too much from a computer? At least I would expect some way of logging in via LAN...  Sad

Normally your Guruplug should catch a DHCP-Adress via Lan if you do conenct him to the upper port (eht0)
(if you got an active DHCP-Server.. e.g. in your Router?)
Otherwise you should see a open WLAN calles Plug-and something of the MAC-Address of your Guruplug.

You could find the Quickstartguide at the URL
http://code.google.com/p/guruplug/downloads/list

Iam also find it curios to put the URL in the Quickstartguide which cant be found without the guide :-)
But Google and the homepage of the manufacturer of the Guruplug is your friend:
http://www.globalscaletechnologies.com/t-downloads.aspx

The login is root/nosoup4u

You are correct! I've been using 1G switches .... pulled out the ol' 16 port 10/100M router and all of the sudden it works fine -- no more rebooting.
because of the fact that I didnt own a Gigabit-Switch I used my 10/100 Switch and my Network Interfaces do work also...no reboot....

What now happens when you connect a cable to eth1? And which cable do you use? The one supplied or another one?
I did use another ethernet-cable.... a 1:1 CAT5 yellow color

I disconnected the cable from eth0 and connected it to eth1, but I didnt get an IP-Adress from my router.
So I reconnected the cable back to eth0 and did get the DHCP-Address and voila I can Login via SSH.

PS: I now that it would be silly to connect booth ports to the same switch/hub :-)

- Guruplug Server or Server Plus?
 - Is your plug on 110v or 220v+
 - Do you have ethernet connected? and if, only ETH0 or 1 or both?

Got no problem (Ok the heat of around 38 degree celsius) with a
- GuruPlug Plus
- 220V/50Hz (Voltmeter reads 216/217V)
- connected to the Ethernet at eth0 (upper port)

Did you connect the eth1 to the same switch/hub like the eth0?

Did you read something about the boot-sequence in this message:

What I found out;
 - If I put a cable in eth0, it doesn't keep working all the time

My Mac is conneted via WLAN to the Guru+ and the Guru+ itself is connected via eth0 (Upper Port) to
a switch which is connected to my Fritz!Box Router.

In this combination the Guru+ is runnign now for 21Hour (around 76.000 seconds in /proc/uptime)

But has the Sheevaplug a bigger cooling system as the Guru+ ? Or is it the little bigger case with more
air in itself because there are less components?

In some cases if have seen USB-WLAN-Sticks getting real hot....so could it be possible that the heat isnt from the cpu
but from the WLAN-Chip?

So if anyone knows how to disable the WLAN (and then when its really getting no mor power) we should take a
look at the temperatur..... I have never seen a hot Bluetooth-Stick.

I attached a weather sensor for temperature on the Guru+ and it has now 37.8 degree celsius -
but feels much warmer/hot than my SheevaPlug with 27.9 degree celsius (both at around 220V/50Hz)
113  Hardware and U-Boot firmware / Hardware / Re: guruplug server plus arrived but died on: May 15, 2010, 03:21:55 PM
I ordered a guruplug server plug in February and received it today. After power it 15-20 minutes on 240V it seems my plug is dead  Cry. No power, no lead, nothing on jtag or UART.

This day my Guru+ is running around 9 Hours (very hot for a plugcomputer) but
it still running:
sheevaplug-debian:/proc# uname -a
Linux sheevaplug-debian 2.6.32-00007-g56678ec #1 PREEMPT Mon Feb 8 03:49:55 PST 2010 armv5tel GNU/Linux
sheevaplug-debian:/proc# more uptime
30692.69 30546.20

The question is...will it run cooler if it is running on 110-120V....how about a stepdown-converter 220->110V?
Could this be a prolblem like on the Sheevaplug? (with or without external devices...where the WLAN/Bluetooth are the new (intern) external devices)?
114  General Category / General Discussion / Re: GuruPlug - Received Yours Yet? on: May 15, 2010, 05:54:24 AM
It's finally April, and I for one expect to receive my GuruPlug before the end of the month. I expect GlobalScale to have placed its production order at the conclusion of the Free JTAG offer/extortion March 1, and by now to have at least received if not begun to ship the first such units hot off the assembly line.

I ordered my GuruPlug Plus in March and did get it now. They sent it at the 05/10/2010 from the U.S. and here in Germany
arrived me at the 05/12/2010...but I could pickup it yesterday at FedEx...

The last month I did get a email from them regrading some FCC-problems, after that they will ship. And here it is now :-)
115  Hardware and U-Boot firmware / Hardware / Re: guruplug server plus arrived but died on: May 15, 2010, 05:33:45 AM
im wondering if anyone else who's seeing this is plugged into 240v (au)? cause mines getting fantastically hot...

Here in Germany my "power-meter" tells something about 216-217V 50Hz and my GuruPlug Plus is getting really warm and does a little
smell like very warm electronics :-((
My SheevaPlug which is running some weeks isnt hot as the GuruPlug :-(

Hope my GuruPlug doesnt die while he is getting so hot....

116  Hardware and U-Boot firmware / Hardware / Re: Poll: Sheeva Plug Power Supply failures - does the mains voltage matter? on: May 02, 2010, 11:37:45 PM
Iam running my Sheeva at 220/20V here in Germany.
But only with SD-Card and a USB-Soundcard (low Power Device).
An external USB-HardDisk should use his own power-supply.
117  General Category / General Discussion / Re: USB-Soundcard for the SheevaPlug on: February 16, 2010, 01:17:39 AM
Iam using the "old" iMic USB-Soundcard which I had from my old Apple Cube....
it working fine with debian

118  General Category / Application ideas and development Q/A / USB-Stick RAID and the Problem with /dev/sda1 on: August 05, 2009, 12:09:07 AM
Hi,
I installed  my SheevaPlug with debian 5.0.2 and the U-Boot for booting from
SDHC-card. This configuration is working fine, but now I got a thing that I didnt understand:

After booting from SDHC-Card (and without any USB-Stick) I got a mount-point which is
named /dev/sda1 and mounted at /
But I think at / should the SDHC-Card be mounted which resides at /dev/mmcblk0(p1/p2)

The problem with this sda-Mountpoint is, when I insert a USB-Stick it also will be mounted as
/dev/sda1

I could see with "fdisk -l" the USB-Stick at /dev/sda1 with the right size,
but when I try to use /dev/sda1 together mit /dev/sdb1 as a mdadm-RAID
the stick doesnt seem to be recognized as /dev/sda1

So how can I tell debian/the sheevaplug to start the FIRST USB-Stick counting at /dev/sdb1 or
mounting (in the mountlist) / at /dev/mmcblk0(p1/p2) ?

For this time my way around the problem is to put at first a not-used USB-Stick in my external 4 Port-USB-Hub (which doesnt do anything as /dev/sda1) and then I do put my (at this time) 2
4GB USB-Sticks for a RAID as /dev/sdb1 and /dev/sdc1


With this configuration I could create and use my USB-Flashstick-RAID at the SheevaPlug USB-Port
which gives me a 8GB /dev/md0-Device:

fdisk -l

Disk identifier: 0x00000000

Disk /dev/md0 doesn't contain a valid partition table


BTW: I dont know why the partition-tabel at /dev/md0 shouldnt be OK.
A fsck for this device did show that the device is clean.

Anybody else try to use a (USB-Stick)-Software-RAID on the Sheevaplug?

Bye

My ideas are to use PlugComputer:
1) As a status screen controller: Attach a display (via DisplayLink) and enable messages to be sent to the screen (RSS feeds, specific messages, etc).

Hi,

the easyiest Way to do that (only Text-Mode) could be a cheap litte VGA-RS232-Controller:
Link
and 2nd Link

Additionally there is Keyboard In and TV-Out....great for Msgs/RSS or Instant Messaging :-))

120  Hardware and U-Boot firmware / Hardware / Re: Loose mini-USB connector on: June 28, 2009, 07:58:33 AM
Luckily, I have another mini-USB-cable with a stem on it that is a mm or two longer than the supplied one,
and that one seems to fit acceptably. 
But, you're right: the mini-USB connector on the plug is recessed enough that not just any cable will
work reliably with it.

Got the same problem with the USB-Port. The USB doesnt seem to "snap-in" like on USB-Port on other devices.
All my USB-cables doesnt click-snap-in like on my mobile-phone ror card reader.
But one of my cables fits a bit better, so that I can use the serial port.
From my point of view the usb is a bit to much recessed into the case.
The connector itself seems to be completly fine soldered to the pcb.
