Another bricked Guruplug, uboot not loading...no serial output

[Griffo]

G'day Everyone,

I've just received my new Guruplug Server from Globalscale and I've already bricked it.  I also ordered and received the JTAG as I was worried I might do this. 

I attempted to upgrade uboot using the guruplug-installer.  Everything seemed to go well until the Guruplug restarted, now it looks like Uboot doesn't load as I get no output on the serial connection.  I still see /dev/ttyUSB0 and when I create the serial session I see the LEDs light up when I type but nothing from the Guruplug itself.

Before this all happened, I was happily connected to the Guruplug via the JTAG in a serial session...

I've spent a couple of hours now trying many different things that I found on the web including:
- re-running runme.sh straight after powering on the Guruplug
- Looping the runme.sh (I'd provide the link to this but I can't seem to find it now)
- Disconnecting and reconnecting everything
- Installing the distro's openocd (Debian Squeeze)

I look forward to everyone's suggestions

Cheers,

Griffo

I had been trying to successfully rerun the guruplug installer countless times and it's finally worked again but still no serial output

Code:

root@BGLaptop:/home/brad/Desktop/guruplug-installer# ./runme.sh ./openocd/uboot.bin
cp: `./openocd/uboot.bin' and `openocd/uboot.bin' are the same file
 ****     Preparing environment variables file ...
 **** Burning uboot and environment variables ... This will take few minutes ...

I'm not sure if it will help diagnose the fault or not, but this is the output I receive when the guruplug-installer fails:

Hello

You are not the only one with that problem. For me it turned out it was ther hardware: https://www.newit.co.uk/forum/index.php/topic,3332.0.html

After installing the U-Boot you have to reset, or even unplug, your GuruPlug.

Dear Griffo,

Did you manage to do anything ? I have the same problem.

Thank you,

Jolann
