`pyocd flash` gets an uncaught exception #782

Trying to use pyocd flash to program an STM32F072VB processor. pyocd gdb works with the same settings. I've tried both python 2 and python 3. pyocd -V reports "0.23.0"

pyocd.yaml:

I have also tried this with the correct target type (after loading the correct CMSIS pack) with the same result.

Hi @bikeNomad , this was thankfully already fixed on master in commit 149556e. Sorry for the inconvenience! I'll shortly release version 0.24.0 that includes this fix.
