Re: Can't write with avrdude and stk200, help please!]

aaahrmmmm...

I solved the problem my self. A classical example of RTFM (all the one's
needed).

This is how i solved my problem(s)

1: The chip needs to be erased first (stupid chip :-)
     avrdude -p 8515 -c stk200 -e
2: Program it
     avrdude -p 8515 -c stk200 -f i -m flash -i demo.hex
3: Now connect a resistor and led to pin PD5
4: Poweron and watch the light!

i bet you all waited to see this before you mail a comment :-)
