Re: [Gumstix-users] Robostix problem

[Lewis H. <lew...@co...>]

Dave,

Thanks for the quick reply!

I supplied the clock to pin 24 to get the AVRISP to reprogram the fuses.

Yes, I have the jumpers as per
http://docwiki.gumstix.org/Robostix_gumstix_ISP

...and no, I have nothing else plugged in to it.

Once the fuses are set for internal crystal, I remove the external clock
from pin 24 and everything works.

If that were the case, then you wouldn't have been able to use AVRISP
without providing an external clock.

I'll give building 1559 a try. I've been using 1574 without any issues.

Just a couple of points to clarify:

1 - You have the two jumpers installed?

2 - You don't have anything plugged into the ten pin header while your
verdex is plugged into the robostix.
