With: https://gem5-review.googlesource.com/c/public/gem5/+/26466 The ArmSystem reset address (_resetAddr) is always forced by the workload: _resetAddr = workload->entry So there is no possibility to manually specify a reset address. This was not the case before: The resetAddr was forced only if auto_reset_addr was true or if there was an associated bootloader to the kernel image. In that case even if auto_reset_addr was false, the reset address was determined by the bootloader entry. This was also not ideal (but it was working) This patch is cleaning all of this: If you want to have automatic detection (recommended), you would need to set auto_reset_addr (now turned to true by default). This will allow to keep most fs script untouched. If you don't want to use automatic detection, set auto_reset_addr to False and provide your own reset address.
