Hi ,
     I am working on the davinci .now I encouter a difficult . By reading the 
dm6446 datum, I have known that the boot mode of dsp core . I think set DSP_BT 
pin to '1' state .using the ccs configure for davinci to emulate it .but I get 
the following errrors :
    Error connecting to the target:
Error 0x80000260/-1137
Fatal Error during: Execution, Initialization, OCS, 
  It appears that the target is being held in reset.  This may be
due to Wait-In-Reset (WIR) configuration set by the EMU0=0
and EMU1=1 pin settings.  If this is the case, DISCONNECT
all CONNECTED devices including icepick and then select
RETRY to clear the WIR configuration.
  If this is a multi-core system, the master CPU may not be
releasing the DSP/MCU from reset.  Please check your
configuration in CC_setup and/or your GEL file to ensure that
nothing is blocking the DSP/MCU from being released from reset
   
  Board Name: DM6446 XDS560 Emulator
Cpu Name: C6400PLUS_0
  Abort:  Close Code Composer Studio.
Retry:  Try to connect to the target again.
Cancel:  Remain disconnected from the target
Diagnostic: Run diagnostic utility.
   
  Who can give me some advise ? Thanks a lot!
