As you can see here, this is not  the  reset  entry  point  (0x0000).
Obviously, the board has been already running some or maybe even many
instructions before it was stopped by the BDI2000.

Check your BDI2000 config file, and check the BDI's runmode.

Probably the function cpu_init() was never  reached.  Either  it  was
executed  long  ago  before you attached to the BDI2000, or the board
crashed before reaching it.

Simply pressing "^C" in GDB will interrupt execution and give  you  a
chance  to  find  out  where  the  program  is running and what it is
currently doing. Also, performing a "mon reset", "mon go" sequence is
probably a good idea as this will allow you to start from  a  defined
state.

Best regards,

Wolfgang Denk

I've got a bad feeling about this.
