Hi, thanks for the reply. I am ex5_big and ex5_LITTLE in the NoC. The protocol is MESI TWO LEVEL. The build statement is as follows.
./build/ARM/gem5.fast configs/example/fs_het.py --l1d_size=32kB --l1i_size=32kB --num-l2caches 4 --l2_size=1MB --cacheline_size=64 --machine-type=VExpress_GEM5_V1 --kernel /home/khilji/gem5/m5/system/binaries/vmlinux-aarch32 --disk-image /home/khilji/gem5/m5/system/disks/arm-ubuntu-natty-headless.img --dtb-filename /home/khilji/gem5/m5/system/dtb/armv7_gem5_v1_big_little_2_2.dtb --num-cpus 4 --cpu-type exynos --big-cpus 2 --little-cpus 2 --big-cpu-clock 2GHz --little-cpu-clock 1GHz --ruby --num-dirs=4 --network=garnet2.0 --topology Mesh_XY --mesh-rows 2 --mem-size 1GB I think that ex5_big has some issues with ruby. Since I have used it separately in a simple NoC with all four cores as ex5_big and got the same issue with fs.py. The build statement for that is following ./build/ARM/gem5.fast configs/example/fs.py --l1d_size=32kB --l1i_size=32kB --num-l2caches 4 --l2_size=1MB --cacheline_size=64 --machine-type=VExpress_GEM5_V1 --kernel /home/khilji/gem5/m5/system/binaries/vmlinux-aarch32 --disk-image /home/khilji/gem5/m5/system/disks/arm-ubuntu-natty-headless.img --dtb-filename /home/khilji/gem5/m5/system/dtb/armv7_gem5_v1_4cpu.dtb --num-cpus=4 --ruby --num-dirs=4 --cpu-type ex5_big --network=garnet2.0 --topology Mesh_XY --mesh-rows 2 --mem-size 1GB --cpu-clock 1GHz --routing_algorithm 1 --work-begin-exit-count=1 --work-end-exit-count=1 Also does ex5_big supports memory map of VExpress_GEM5_V1? May be that is the issue. The ex5_LITTLE has no issue when it is used in the above NoC with four cores.Any suggestions ? best regards, Sharjeel On 25 August 2017 at 16:58, Nikos Nikoleris <nikos.nikole...@arm.com> wrote: > Hi Sharjeel, > > > Can you provide some more information about your simulation setup?
