Hi Pedro, I tried this test and noticed the same problem. However, the test seems to work if you use example/se.py script. For example, following command worked:
build/ARM/gem5.opt configs/example/se.py -c tests/test-progs/hello/bin/arm/linux/hello --cpu-type=TimingSimpleCPU --caches I would suggest you to look at m5out/config.ini files from both runs and see what's different between the two configurations. That might help you to figure out how to modify your simulation script to make it work for ARM. -Ayaz On Wed, May 10, 2023 at 9:39 AM Pedro Corrêa Rigotto via gem5-users < gem5-users@gem5.org> wrote: > Good afternoon. > I encountered this error while trying to run an ARM configuration with one > of the scripts in the learning_gem5 folder.
