Another non-x86 issue (dependency on pypemicro) #1133

Open Spivoxity opened 3 years ago

Spivoxity commented 3 years ago

In addition to the known problem with installing cmsis-package-manager on Raspberry Pi, a new problem has appeared in version 0.30.3, caused by the dependency on pyocd-pemicro and pypemicro. When pyocd is started, it tries to load these modules and the library unitacmp-64.so that they use. If fails to find the library and crashes.

As far as I can see, the unitacmp-64.so library is closed source and not available for Raspi OS. But in any case, it seems a shame to require it to be installed in order to use some other debug adapter -- in my case, the built in debugging interface of the BBC micro:bit.

Perhaps a solution would be to remove the dependency of pyocd on pyocd-pemicro, and let those who need it install the add-on by hand. My workaround is to remove the dependency from the pyocd metadata file, like the dependency on cmsis-package-manager, before installing. The GDB server works fine without them.

With best wishes, -- Mike Spivey

See the "installing pyocd" section here:

I was wondering if one way is for pyocd-pemicro to depend on pyocd instead of other way around? Then if one needs PEMicro support it can be installed at one go?
