ImportError: Can't find a path to system files.
When I try to run the simulator and I get an error: ImportError: Can't find a path to system files.
- You have not installed the full-system files (disk images, kernels, and other binaries) or have not setup the path to them correctly. See Getting Additional Tools and Files.
If you want to run the full-system version (including the full-system regression tests), you will also need to download the full-system files (disk images and binaries). Kernels, disk images, and boot loaders for Alpha, ARM, and x86 are available on the Download page. SPARC disk images are available on the with the OpenSPARC Architecture tools
可以通过configs/common/SysPaths.py 或者环境变量M5_PATH
但是很遗憾，文件失效了
- X86
- Full System Files -- The kernel used for regressions, an SMP version of it, and a disk image
- config files -- Config files for both of the above kernels, 2.6.25.1 and 2.6.28.4
