Hi,
I am trying to run ARM FS with ruby. The error I have now is the following:
gem5.debug: build/ARM/mem/ruby/system/RubyPort.cc:418: virtual void
RubyPort::M5Port::recvFunctional(PacketPtr): Assertion
`ruby_port->pio_port.isConnected()' failed.
Program aborted at cycle 0
Aborted
Clearly I messed up some port connection, but I can't find it. I was having
problem in hooking up a dma device, then I think I don't have to use a dma
device (do I?). The following is the class that create an ARM system with
ruby. Can someone please help point out what goes wrong? Thank you.

False):
