Hi Pedro,
I'd recommend you to rely on the "configs/example/arm/starter_fs.py" script
instead and, with M5_PATH pointing to the
/home/pedro/Projects/gem5/fs_files/aarch-system-201901106 folder, simply run
with
build/ARM/gem5.opt configs/example/arm/starter_fs.py \
--kernel $M5_PATH/binaries/vmlinux.arm64 \
--disk-image
=/home/pedro/Projects/gem5/fs_files/ubuntu-18.04-arm64-docker.img \
--root /dev/vda
Let me know if it works
Kind Regards
Giacomo
