Hi, This is probably happening because 20170616/disks/linaro-minimal-aarch64.img is using the old m5 binary and as such it doesn't support the runtime --addr option (which has been added after 2017) I recommend you to either rebuild the m5 binary and replace it in the disk image, or to use the [1] disk image available at [2].
As you are running with KVM, you should be using the /init.addr.gem5 init script (so amend the kernel cmdline accordingly) Kind Regards Giacomo [1]: http://dist.gem5.org/dist/current/arm/disks/ubuntu-18.04-arm64-docker.img.bz2 [2]: http://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries > -----Original Message----- > From: kong han via gem5-users <gem5-users@gem5.org> > Sent: 06 April 2021 15:50 > To: gem5-users <gem5-users@gem5.org> > Cc: kong han <han.k...@outlook.com> > Subject: [gem5-users] --script can't be read when using kvm > > Hi all, > > Now I run the KVM CPU and use the -script params to write the rcS script file > to the image.
