Hi, If I run bbench with gem5.debug, I immediately get an error in the code however, gem5.fast doesn't fail at that point. In fact it will fail after so many ticks.
A bit strange... Any idea on that? I haven't modified the code yet. gem5.debug warn: DTB file specified, but no device tree support in kernel **** REAL SIMULATION **** warn: Existing EnergyCtrl, but no enabled DVFSHandler found. info: Entering event queue @ 0. Starting simulation... warn: Device system.membus.badaddr_responder accessed by read to address 0x10009018 size=4 gem5.debug: build/ARM/cpu/simple/atomic.cc:378: virtual Fault AtomicSimpleCPU::readMem(Addr, uint8_t*, unsigned int, unsigned int): Assertion `!pkt.isError()' failed.
