What's up with dualcore system?

I have built a single cpu system with onchip memory, it works well. However,after adding another cpu and another jtag to the SOPCBuilder, and the total component of it is : cpu*2,jtag*2,onchip RAM...

A couple of things to watch out for:

1 - Are you connecting to the right CPU. If you are using the software build tools or nios2-studio, you can get yourself into trouble here. You may have to manually specify in the debug profile which jtag node id to use when connecting to the processor.

2 - Are you using a jtag uart? If so which cpu is connected to it?
