Error while burning bootloader.

The OpenOCD .path link does not work, tools.openocd.path={runtime.tools.openocd-0.9.0-arduino.path}. With the arduino Zero is is now tools.openocd.path={runtime.tools.openocd-0.9.0-arduino6-static.path}

Platform: OSX 10.11.6
Arduino IDE: 18.2
Sparkfun library: Sparkfun SAMD boards 1.3.2

Ah see now I have the wrong Arduino SAMD library: 1.6.15 (should be 1.6.9)

Thanks for finding this @FRVisser! (Sorry for the delay.)

I just committed a fix for this along with a larger update to the samd core. Burn bootloader seems to be working on my end, feel free to re-open if it gives you any trouble.
