[avr-libc-dev] stk500 and tiny45

[David Carr]

Thanks to Joerg, Anatoly and Eric et all. I have toolchain that
completely supports the tiny45.  I can't however convince my STK500 and
avrdude to program the thing.  I using SCKT3400D1 and avrdude 5.1.  I
also have a jumper from PORTE-RST to PB3.  Has anyone made this work?

Thanks,
David Carr

I get the following output: Note that device signature is sometimes
different.
