"system id mismatch" error for multiprocessor application

Firstly, thank you very much for your answer.Actually, both CPUs are used the same system id component . Because, the name of the system id component must be "sysid" so that i can put only one in SOPC builder. actual read value is 0xffffffff .expected value changes after the compiling process. In my opininon there is something wrong in NIOS II IDE platform because this problem is occurs only for the cpu2 project.After changing their BSP projects, still cpu2 project gives same error. So, there is nothing wrong in the bsp projects. I read the documents about NIOSII multiprocessor application however there is not any useful idea about configuration of multiple debugging in NIOSII. they gave the make files and said that import them that's all.
