Hi, I found that problem was with Linux kernel. I get a panic in kernel while booting for single core at the end. I get no init found.
./build/ARM/gem5.fast configs/example/fs.py --machine-type=VExpress_GEM5_V1 --kernel /home/khilji/gem5/m5/system/binaries/vmlinux --disk-image /home/khilji/gem5/m5/system/disks/linux-aarch32-ael.img --dtb-filename /home/khilji/gem5/m5/system/dtb/armv7_gem5_v1_1cpu.dtb --num-cpus=1 --cpu-type=timing --mem-size=1GB --num-dirs=1 I am using the latest kernel at following link v4.4 https://github.com/gem5/linux-arm-gem5/commits/gem5/v4.4 <https://github.com/gem5/linux-arm-gem5/commits/gem5/v4.3> I am compiling it with following make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- gem5_defconfig make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4 I think that default configurations are not working. This kernel has support for VExpress_GEM5_V1 platform. Kindly, if you can guide me about which configurations to use. best regards, sharjeel On 21 February 2017 at 20:32, Jason Lowe-Power <ja...@lowepower.com> wrote: > Hi Sharjeel, > > I think you've found another case where ARM isn't supported in Ruby.
