Based on that response, I would guess that your BDI2000 is not yet
configured and connected to the target yet, i.e. the BDI2000 has
not successfully detected any target CPU on the JTAG chain. Try
using `telnet 192.168.226.159` to see what's going on with the
BDI2000. Also, try referring to the BDI manual for help configuring
the BDI and, of course, talk to your processor/board vendor to
resolve BDI setup/config details. Does the BDI2000 even support ARM11
based processors yet?
