Does it really raise a NameError? Or an UnboundLocalError?

You probably want

def func2():
     global A
     A = A + 'hi'    # this line causes the error
     print A

You probably know that "from X import *" is considered bad style, BTW.
Also, I'm not sure if the code I wrote will do what you want it to.
Assigning to A in one module rebinds it in that module. I don't think it
will have any effect in the other module.
