Hey Guys.
I made a custom hardware with an Atmega2560-16AU Microcontroller and I'm not able to burn the bootloader to it.
My Hardware is quite simple, the MCU is powered with 5V, there are 5 100nF Capacitors next to each VCC Pin (10, 31, 61, 80, 100). Reset is pulled up with a 10k Resistor and a 100nF Decoupling capacitor. And there's a 16Mhz Crystal Oscillator with 2 22pF Capacitors and a 1M Resistor between Pin 33 and 34. And of course the ISP Header.
By now nothing else is connected.
I'm using the USBASP Programmer (this one: USBASP
When I try to burn the bootloader, since the MCU is brandnew, I get this Error Message:

avrdude done. Thank you.
Chip-Löschung fehlgeschlagen: Hochladefehler: exit status 1
My USBASP is working correctly because I tested it on a custom Atmega8 Board and there it works without a problem.
Hope someone can help
