Either one. The "virtualenv -p /usr/bin/python3 env" sets up an 
environment that uses python3. Look in the resulting env/bin directory 
and you'll see python is a link to python3. After running "source 
env/bin/activate" your PATH is changed to use the python and pip from 
the env/bin.

They're not the exact same file, but both are bitstreams to load into 
the FPGA. There's a pre-built bitstream you can download 
http://j-core.org/numato.bin or you can build your own which gets named 
mimas_v2.bin. If you've built mimas_v2.bin, then that's likely the one 
you want to pass to MimasV2Config.py to load.
