Re: [Gumstix-users] Robostix not responding with AVRdude

[Karthik <k.i...@gm...>]

Hi Dave,

Yes, definitely powercycled and tried on a different machine.  Green LED
still comes up, and I used a scope to test the 3.3 and 5V terminals as
specified in the Robostix troubleshooting page.

Thinking about it, I wonder if something fishy (electrically) happened while
programming the fuse.  The olimex cable is quite short, so the robostix is
just dangling off the connector on the back of my desktop among all the dust
and what have you.

How might I approach the problem if the fuse was incorrectly programmed?  I
don't know if this is the case, but I am also confused how loading a hex
would cause such problems.

Thanks,
Karthik
