运行gem5全系统模式时出错

Question

我尝试在完全系统模式下运行gem5时遇到此错误。我遵循的是这个指南：https://github.com/arm-university/arm-gem5-rsk/wiki

你知道怎么解决这个问题吗?或者armv8_gem5_v1_1cpu.20170616.dtb是什么？

tomas@ubuntu:~/gem5$ ./build/ARM/gem5.opt configs/example/arm/starter_fs.py --cpu="minor" --num-cores=1 --disk-image=$M5_PATH/disks/linaro-minimal-aarch64.img
