Hello,
It seems i've bricked uboot on my guru server plus.
So try to reflash uboot with installer
What i've done is:
1. i downloaded installer from:
http://www.plugcomputer.org/index.php/us/resources/downloads?func=select&id=162. and image from:
http://code.google.com/p/guruplug/downloads/detail?name=Guruplug%20server%20PLUS%20-%20uboot.plug2.bin.zip&can=2&q=3. run installer with command:
sudo ./runme.sh uboot.plug2.bin
4. I get error from the bottom of this post
I'm sure JTAG isn't bricked because i can connect with it to another (not bricked plug)
Any clue what's wrong ?
