Hi
The command line refers to the URL：http://www.m5sim.org/TraceCPU 。The
difference is that I want to simulate an android application in full system.
Sometimes ,when I reduces the simulated instructions,it can work, such as
add "-I 1000" in the command line. However, I can not figure out why in
cannot simulate the whole process.
Regards
crown
