Hello,
Thank you for your replies - turns out I was using an ancient build of gem5
while bbench comes only with a recent version.
However, cloning the latest repo and trying to run bbench on it gives me
this error -
command line: build/ARM_FS/gem5.opt configs/example/fs.py -b bbench
Memory being used by default: 256MB
Global frequency set at 1000000000000 ticks per second
Listening for system connection on port 5900
Listening for system connection on port 3456
fatal: system.iobus has two ports with same range:
system.realview.realview_io-pioport
system.iobridge-slave
@ cycle 0
[recvRangeChange:build/ARM_FS/mem/bus.cc, line 493]
Memory Usage: 376964 KBytes
I noticed on the earlier threads that this happens due to incorrect
specification of memory. However, I haven't changed anything in the default
build.
How do I resolve this?
Regards,
Kirtika
