[En-Nut-Discussion] Ethernut major failure.

[Alastair Jeremy]

Hi Lars,

what software were you using to program the fuse bits?

and do you have a second ethernut, or some form of 5v square wave signal
generator?

i had a similar problem once because i switched off the oscillator, but
managed to fix it by injecting a signal into the clock (from a second
ethernut with a program to make a square wave on it).

Alastair

Hi All,

I have really messed up!

I was going to set some fuse bits on the Ethernut and did something wrong
and now
I can't get any contact with the board using my ISP dongle. When I try to
get the
chip signature I get "0xFF 0xFF 0xFF, chip unknown."

Does anyone know in what ways I can reset everything back to normal?

Regards,
/Lars
