16  General Category / General Discussion / Re: GuruPlug Server Plus REBOOT!!! on: February 09, 2011, 09:49:47 AM
I am having the exact same issue as the GuruPlug simply reboots whenever I plug in the second network table. I am not sure whether the problem is with the kernels since I have tried more than three already. Also please tell whether this has to do anything with the JTAG module?

Notice:  u-boot and uImage/kernel they do have dependencies,

i have 2xgps+  and don't have that problem
eth1 = wan 100mbit
eth0 = lan 100mbit
jtag (is always enabled/connected)

at first flash this great u-boot:

do set you uboot-params correctly

retry to boot

if that still doesn't work

Hi rickyleeb,

 I'm able to set all the environment variables except the first one, when I run the 'setenv bootcmd' plus all the options, the command is just executed, so, I'm not able to store the value. What's going wrong???

Thank for your help,


i think "setenv" must'nt be there, to define uboot-var.  "ethact"   and "bootcmd", you've to enter (in uboot):

setenv bootcmd   '${x_bootcmd_ethernet}; setenv ethact egiga1; ${x_bootcmd_ethernet};'
setenv ethact egiga0;

(don't forget the 'quotes')

21  Linux Stuff / General Linux questions / Re: [GURUPLUG+] Problem with rtorrent on: December 22, 2010, 07:28:28 AM
on my gp+ i  installed  2 months ago rtorrent, out-of-the-box (synaptic/apt-get), no need to complie,
it's running 24x7, no problems at all.
advise: nat the torrent port on your router/fw

i have
one gp+ with eth1 connected to WAN, and eth0 to LAN, this gp+ is router, gw, fw, dhcpd->lan, dhcp->cablemodem, nfsd, networkinterfaces both running at 100mbit, no heat-problem, getting light warmer then :
the other gp+ (eth0 - 100mbit, rTorrent, sabnzbdplusd 24x7, smbd, nfsd, mediatomb-TV), no problems at all.
23  Hardware and U-Boot firmware / Hardware / Re: How to power your Sheevaplug from the Usb without opening the case. on: December 18, 2010, 04:05:00 PM
James, interesting. Is this a special USB hub (or would "any typical" powered USB do)?
just for fun i just tested my gp+ with an old standard qtec 4-port usb 2.0 - hub (10euro's - 5 years ago), 
output power-supply : 6v - 2100 mAmp,
my gp+ stills runs after ejecting the main power-cord (220V) of the gp+ ,
ther's a tiny problem: when i try to reboot the gp+, it is powered off just before restart..
24  Hardware and U-Boot firmware / Hardware / Re: new kernel on a guruplug on: December 15, 2010, 03:54:04 AM
i think you need a more recent uboot, because of the new kernel you flashed, so try this:
# read, download and flash uboot

# read, download and flash kernel, install/upgrade debian
# read

26  Linux Stuff / Linux distributions / Re: Newer kernel, RFS + uBoot for Guruplug ? on: December 09, 2010, 04:36:46 PM
Does anyone know if there is a newer kernel, RFS or uImage that might actually give reliable WiFi when running Debian on a Guruplug ??

I constantly get kernel panics, but only when the wifi device is active (ifdown wlan0 cures this) which defeats the point of having the plug for me.

If someone is able to point me in the right direction, I would be most grateful.

just  follow   http://oinkzwurgl.org/guruplug
works excellent !!!

i think i just murdered my guruplug ... went through the download and compile (i think) of a new kernel and then tried to upgrade uboot ... rebooted as instructed, and now it's not booting anymore ... i looked around, and it says that i should be able to plug in a usb mini, but there's no port, and i am supposed to have a 'connector', which, of course, i don't ... so, how do i get this thing up again ... i shall keep researching this, but any help is greatly appreciated ... theo

you need a jtag connected to your guruplug, the jtag has a mini-usb ,
the mini-usb / usb cable needs to be connected to a pc/laptop, so you are able to connect to the serial port of the guruplug
-- use putty (windows) or minicom/picocom on your linux-pc  --

because of the used blocksize:
your first dd uses blocksize 1024
your 2nd dd uses blocksize 512 (implicit)

your gp+ has a static ip on eth0,
your gp+ is connected to your router.
i suppose that your router is in the same subnet as your eth0-port of the gp+
so try to ping & connect by ethernet, not by wlan

the default ip of the gp+ on eth0 is
(you should read :   

in case your routers ip is you have to change that ip of course, else you get duplicate ip's and conflicts !
