Closed flit closed 3 years ago

The following exceptions occur if the pyocd-pemicro plugin is installed, but not the PEMicro drivers, and you attempt to run pyocd list.

On macOS 10.15:

RaspberryPi looks similar with a slightly different error message:

0002117:CRITICAL:__main__:uncaught exception: unitacmp-64.so: cannot open shared object file: No such file or directory

I will look at it, the Linux is generating different kind of exception and I don't catch it in caller function as on Windows, thanks for reporting.
