Dual-core simulation failed

[JackyWu526]

Describe the bug
使用make verilog NUM_CORES=2生成两核的代码，make emu -j32生成仿真环境，再./build/emu -i ./ready-to-run/linux.bin执行仿真，结果出错。请问双核测试的bin文件需要重新生成吗？上面的操作步骤准确吗？我如何才能跑起双核测试，谢谢！

Use make verilog NUM_CORES=2 to generate dual-core code, make emu -j32 to generate the simulation environment, and then ./build/emu -i ./ready-to-run/linux.bin to execute the simulation, and the result is wrong. Does the bin file for the dual-core test need to be regenerated? Are the above steps accurate? How can I run the dual-core test, thanks!
