Hi All:
I use the GEM5 v20.0.0.1 with dist-gem5.sh, my cmd is
“bash $DIST_M5/util/dist/gem5-dist.sh -n 2 -r $DIST_M5/rundir -c
$DIST_M5/ckptdir -s $DIST_M5/configs/dist/sw.py -f
$DIST_M5/configs/example/fs.py --fs-args --kernel=$M5_PATH/binaries/vmlinux
--machine-type=VExpress_GEM5_V1
--disk-image=$M5_PATH/disks/expanded-aarch64-ubuntu-trusty-headless.img
--cpu-clock=2GHz --mem-type=DDR4_2933_16x4_new --mem-ranks=4 --mem-size=16GB
--sys-clock=1600MHz --num-cpus=2 --cpu-type=ArmV8KvmCPU --cf-args
--ethernet-linkdelay=10us --ethernet-linkspeed=10Gbps -x
$DIST_M5/build/ARM/gem5.opt --m5-args --debug-flags=DistEthernet”
But it will fail to bootup with the error log below, any one has some
experience on it?
