The program correctly ouput, but but when I checked the cache usage, it seems that the cache is not working properly (both tag and data access are 0):
When I look at the cache debug information, it seems that all requests are 'Uncacheable' and all cache blocks are in 'Invalid' state. What could be the possible reasons?

I compiled a baremetal workload and ran it in fs mode under gem5:
build/ARM/gem5.opt --debug-flags=Cache configs/example/fs.py --cpu-type=ArmO3CPU --caches --l2cache --kernel tests/test-progs/main.elf --machine-type=VExpress_GEM5_V1 --bare-metal
