Using the CC Debugger 

After  having  connected  the  debugger  to  the  target  device,  the  debugger  can  be  powered  up  by 
plugging in the USB cable.  
 
The  debugger  will  immediately  start  a  device  detection  process,  looking  for  all  known  devices.  If  no 
devices are detected, the LED will be RED. If a device is detected, the LED will be GREEN.  
 
If the LED is GREEN, it is possible to start using the debugger together with one of the supported PC 
tools. 

7.1 

Understanding the LED 

OFF

 

 

The debugger has no power or there is no valid firmware on the debugger. 
Make  sure  the  debugger  is  properly  powered  via  the  USB  cable  or  try  to 
resurrect the debugger using the method described in chapter 8.4. 

 
AMBER (BOTH LEDS ON) 

 

The  debugger  is  powered,  but  there  is  no  valid  firmware.  Try  to resurrect 
the debugger using the method described in chapter 8.4. 

 
RED LED BLINKING

 

 

The Debugger is in Boot Recovery Mode. 
 
The  debugger  will  briefly  enter  this  state  while  the  firmware  is  being 
upgraded  (see  chapter  8).  The  board  might  also  enter  this  state  if  the 
firmware is corrupt or if the user has manually forced to board to start up in 
the special “boot recovery mode” (section 8.3). 

 

To go out of the state, reset the debugger by pressing the “Reset” button 
or  by  power-cycling  the  device.  If  the  LED  is  still  blinking,  reprogram  the 
unit by using the Flash Programmer Application. 

 
RED LED ON

 

 

No  device  detected.  This  might  be  due  to  old  firmware  on  the  CC 
Debugger. New devices might not be supported with the current firmware 
on  the  debugger.  Please  refer  to  chapter  8  for  the  firmware  upgrade 
procedure. 
 
There  might  also  be  a  problem  with  the  hardware  connection.  Check  the 
connection to device and make sure the target board is properly powered 
and  that  Vdd  on  the  target  board  is  connected  to  pin  2  on  the  debug 
connector.  Press  and  release  the  reset  button  to  retry  the  target  device 
detection 

 
GREEN LED ON

 

 

The target device has been properly detected. It is possible to start using 
the supported tools (see chapter 5.2).
