I want to burn a bootloader on my stand alone board. But I get the following error:

Open On-Chip Debugger 0.9.0-g932ec70 (2017-02-15-12:33)

Fout bij het branden van de bootloader.

I use the setup in: http://forum.arduino.cc/index.php?topic=364358.msg2521277#msg2521277

I use a small 5 inch ribbon cable from my board to the SWD connector to the Zero PRO.

Can anyone tell me what i'm doing wrong?
