Thank you for the info, I didn't know that RTS and DTR works.
I made a better picture with a higher resoultion and some description: 2,8MB Picture
I have two caps between VCC and GND (AVCC and GND). And there is one cap between Pin 9 (Reset) and DTR. I checked TX and RX, at first it was correct then I swap them so it wasn't correct anymore so know it is the right way but the error message is the same: avrdude: stk500_getsync(): not in sync: resp=0x00
