Hi All, Some of the links suggested that checkpoint should be created using the default CPU and without any cache configuration as input. I made the suggested changes in the command, but it still, on restoring, I am getting the same error. Following is the command that I am executing to take checkpoint
./build/ARM/gem5.fast configs/example/fs.py --script=./configs/boot/hack_back_ckpt.rcS -n 4 --machine-type=VExpress_EMM --kernel=../linux-linaro-tracking-gem5/vmlinux --dtb-filename=../linux-linaro-tracking-gem5/arch/arm/boot/dts/vexpress-v2p-ca15-tc1-gem5_dvfs_per_core_4cpus.dtb --disk-image=../disks/arm-ubuntu-natty-headless.img --cpu-clock=[1 GHz,750 MHz,500 MHz] Could you please shed some light?
