empty vcd files
Hi all, I am trying to study gem5 RTL. when I trying to reproduce the result(the rtlFIFO example and the rtlPMU example), I got a problem. The generated vcd files are both empty, is there something wrong? I download the latest Linux Kernel Image / Bootloader from "https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries", and modify "configs/example/arm/fs_bigLITTLE_RTL.py" as follows: default_kernel = 'vmlinux.arm64' default_disk = 'ubuntu-18.04-arm64-docker.img'
Thanks, Gao
