Hum... what's up doc...

The green led was lightening an hour ago.. and suddently, no led !
I have opened the guruplug to check the Power supply : sounds good! and I don't think it has burned as I can see on lots pictures on that forum...

NB: it was plug 24/24 7/7 since more than 3 years (w/o Wifi nor bluetooth)

Please, give me advices and thank you.

Hello,

Today I'm facing a new issue on my guruplug.
I don't know why nor when exactly, I have lost eth connection to guruplug.

I tryed to reboot, but unfortunately, guruplug didn't boot correctly. I don't know why...
So I decided to plug the jtag to see what happened on the console. I usually got the u-boot messages and the log booting messages displayed. But nothing is displayed today; black console screen.

I never installed minicom on my old xubuntu desktop. I was using putty on Serial over /dev/ttyUSB0 speed=115200

Putty setting didn't changed on my desktop (tryed both Windows and Linux Xubuntu) and I was connecting well and instantaneously few weeks ago.. but today, it didn't connect.

Guruplug has the green led lightened..

What would you suggest ?

Thanks for your support.

Have you tried my script, but replacing "guruplug" with "plug2"?

ok, I just have tried ; but I have the same issue.
To be clearer, I've noticed that the green leds that is still lighten is on the bottom of the plug whereas "/sys/class/leds/plug2\:green\:wmode/brightness" controls the right (or left) leds...

echo 0 > /sys/class/leds/guruplug\:green\:wmode/brightness
return me this error : "/sys/class/leds/guruplug:green:wmode/brightness: Aucun fichier ou répertoire de ce type"

but...
Code:
ls -la /sys/class/leds/
total 0
drwxr-xr-x  2 root root 0 jan  2 14:32 .
drwxr-xr-x 30 root root 0 jan  2 14:32 ..
lrwxrwxrwx  1 root root 0 jan  2 14:34 plug2:green:health -> ../../devices/platform/leds-gpio/leds/plug2:green:health
lrwxrwxrwx  1 root root 0 jan  2 14:34 plug2:green:wmode -> ../../devices/platform/leds-gpio/leds/plug2:green:wmode
lrwxrwxrwx  1 root root 0 jan  2 14:34 plug2:red:health -> ../../devices/platform/leds-gpio/leds/plug2:red:health
lrwxrwxrwx  1 root root 0 jan  2 14:34 plug2:red:wmode -> ../../devices/platform/leds-gpio/leds/plug2:red:wmode

But in fact  have the same result : green leds still light but I can control the red one !
5  Hardware and U-Boot firmware / Hardware / "turn off" guruplug led on: December 20, 2010, 12:24:47 PM
Hello All,

I have got my guruplug server since this summer and I really wants to turn off all the leds (green).

I've executed as root a script with theses lines, no error from shell but leds are still green !
Code:
#!/bin/sh

echo "none" > /sys/class/leds/plug2\:green\:health/trigger
echo "none" > /sys/class/leds/plug2\:green\:wmode/trigger
echo 0 > `eval ls /sys/class/leds/*plug*\:green\:health/brightness`
echo 0 > `eval ls /sys/class/leds/*plug*\:green\:wmode/brightness`

How can I switch off all the lights ?

> You should use the normal shutdown
And... what is the normal shutdown ? Are you talking about "shutdown -h now" ?

Hello,

When I wants to unplugged the guru, do I have to "sudo halt" before ? or can I unplug it roughly ?

ok, I managed to connect to the guru with a  winXP OS... not funny for me but I solved my issue.

oh, I'm using xubuntu 8.04...
So I've tryed to install minicom : looks good
Then I configurate it (sud minicom -s) to have "Serial device set to /dev/ttyUSB1" and "Hardware Flo Control to No" (as described into the QuickStartGuide)
Then I run "minicom -o marvell" (with or without sudo ?) and I plug my Guru ;

But now, on the top left I can see
Code:
Bienvenue avec minicom 2.3-rc1
OPTIONS: I18n
Compilé le Dec 10 2007, 10:36:19.
Port /dev/tty8
Is this ok ? Do I have to wait long period (more than 2 minutes) ?

please, note that, when I run "dmesg | grep tty" with jtag plugged, I've got
Code:
[   10.717413] console [tty0] enabled
[   12.969778]   hash matches device ttyc5


NB : minicom version 2.3-rc1 (compilé le Dec 10 2007)
10  Hardware and U-Boot firmware / Hardware / Need help to debug my guruplug, jtag howto on: July 16, 2010, 02:55:48 PM
Hello,

I'm new user with a guruplug standard... and one day after lunched it's yet down...
In fact I've done a mistake in my /etc/interfaces file (using SSH) ; and then I restarted the neworking service. Consequently, SSH connection has shut down !

Good news : I've byed the jtag, and I thik it  could be usefull for me :-)
Bad news, I'v read that I must use fedora to use jtag and I'm used to have xubuntu ;-( Is it possible to use jtag with fedora core 13 live CD ?

Does I have nother way to restore my networking service ?

Thsnks !
