[Fwd: Re: [avr-chat] avrdude high-voltage programming]

[Robert von Knobloch]

Thanks for your advice Markus,  I have solved the problem.
I had a very unpleasant hardware fault on my STK500. Quite why it
appeared to work under AVR studioa nd not under AVRDUDE is still a
mystery - but that's life.
Although I bought it new, from a reputable shop, once I started really
looking closely I noticed that it had been soldered in some places. The
high voltage generator had all 4 transistors blown, so I had to replace
them.
Allworks fine with AVRDUDE now.

EDIT: I have never even touched the HV programmer, but from the Invalid
device signature i got the idea, that this might help.

    looks like problem i had with AVRISP2.  What i did was to change SCK
    on avrdude. 

    $ sudo avrdude -c avrispmkII -P usb -p m88 -F -u -t

    i did set it on 4 and it started to work like charm.

    Maybe usefull
