Hey guys,
Just ran into this myself. The IO bridge is being instantiated twice,
once in FSConfig.py and again in the fs.py file. I was able to fix it for
X86_FS simply by adding an if clause in the fs.py file (line 166) where it
is instantiated the second time:
if not test_sys.iobridge:
test_sys.iobridge = Bridge(delay='50ns', nack_delay='4ns',
ranges = [AddrRange(mem_size)])
test_sys.iobridge.slave = test_sys.iobus.port
test_sys.iobridge.master = test_sys.membus.port
I'm not sure if this would upset other architectures though.
