It looks, to me, like you've not programmed your FPGA or you have no debugger built into your processor, though you clearly state that you have. What does a "jtagconfig -n" command return from within the SDK shell? You should see something like this:

1) USB-Blaster 
  020840DD   EP1C20

    Node 0C006E00

The two "nodes" listed, above, are the debugger and the jtag_uart, in my case.

Also, make sure you're not using an OCP version of the processor, as that requires that you keep the programmer open.
