Hi,
I've been succesfully building hex files with WinAVR and programming 
them with AVR Studio 4 (and the original Butterfly bootloader)... until 
the cable broke in the middle of programming.
Now, I can still program, but verification fails:

"Address: 0x0000, Expected: 0x940c, Received: 0x2121"

and nothing runs...
What's happenning, why that address?
I thought if 0x0000 is toast, the bootloader shouldn't work either... 
nothing should work.  
Obviously, something still works, as pushing the button down allows 
AvrProg to connect, and program.

Is it toast?  Would ISP programming fix it?

Thank yo,

Cat

Hi,
Did this get lost, or nobody hadthis problem before, therefore nobody 
can help?

ISP should fix it, read here for the whole story:

Just saw BootLoader replacement for that problem over at AVR Freaks 
called Superfly. Might want to check that out.
