Hello,
I am using gem5.20 and trying to run the hello world program in se.py using
HMC, but I’m getting an error saying I’m trying to initiate an orphan node.
build/X86/gem5.opt configs/example/se.py
--cmd=tests/test-progs/hello/bin/x86/linux/hello --mem-type=HMC_2500_1x32
Traceback (most recent call last):
File "<string>", line 1, in <module>

peer_port = peer.simobj.getPort(peer.name, peer.index)

ccobj = self.getCCClass() if static else self.getCCObject()
File "build/X86/python/m5/SimObject.py", line 1662, in getCCObject
raise RuntimeError("Attempt to instantiate orphan node")
RuntimeError: Attempt to instantiate orphan node
Does anyone know what might be the cause and the solution for this?
Thank you,
Hessa.
