Hello Galen.
I should have written it to the list. I found the problem: I did put the chip into the wrong socket. Not A03 but D03. The s8515 needs to be in the D03 and the m16 in the A03. Everything works perfect. Thanks for answering though.

My setup is working fine with an at90s8515. I use MacOS, a usb2serial, a stk500, and avrdude 4.4.0.
As soon as I switch from the at90s8515 to the atmega16, I get the following error when I try to program it: failed to enter programming mode.
Below I attached the output of "-v -v -v -v".
Does anyone had similar problems and found a solution for it?
The default clock speed for a mega16 is 1 MHz. SCK speed needs to be less than or equal to one quarter of the clock speed. Try setting the SCK period to 5 us. Below is an example of how to do this. This may not be your only problem. Are you programming in-circuit, or are you inserting the devices into the DIP sockets of the stk500?

avrdude done. Thank you.
