RE: Bricked Sheevaplug



Hello,

You can try to reflash uboot binary with openocd.
You need to keep reset switch while power up your plug.
You'll then have to send openocd reflash command in the next few seconds.

I'll try to give exact command and a ready to use config file later.
For now I'm still far from my computer...

Regards,
Gérald

This is precisely the problem: it is _NOT_ coming up with serial console and there's no obvious record of it on the network. I see some activity on hard reset from 
blinking lights - but I can't get any further.
