4.2.1  dBUG ROM Monitor Power-up 

When you start up your ColdFire LITE Development Kit in Tera Term, the dBUG ROM Monitor 
will appear.  The dBUG ROM Monitor is programmed into the Fire Engine’s boot Flash device. 
 

Accessing dBUG 

 
Interface to dBUG via a terminal emulation program connected via a null-modem serial cable to 
the “Terminal” port of Fire Engine (Serial Port 0, top on the baseboard).  Use the following default 
terminal settings: 19200 baud, 8-data-bits, 1-stop-bit, no-parity, and no-flow-control.   

 

1  Start a terminal program on the host computer (i.e. Tera Term, HyperTerminal, etc.).  

Connect a serial cable to the host computer and to the Serial Port on the CDK. 

 

3  Apply power to the Fire Engine.  
4  In the terminal program you should now see a dBUG screen presenting text similar to this:

Enter 'help' for help.

Note: If the dBUG Monitor screen does not appear, please check Tera Term serial settings, all 
cable connections, board connections, and press system reset. 

 

5  Logic recommends that you immediately increase the baud rate for faster downloads and for 

ease of interfacing to LogicLoader. To do so, enter the command ‘set baud 115200’ at the 
dBUG prompt.  Next, adjust the baud rate on your terminal emulation program to 115200. 
Then press System Reset and you should see the startup screen that you saw in step 4. 
Since the dBUG monitor program stores its settings in flash, the higher baud rate setting will 
remain in effect until the next time it is changed. 

4.2.2  LogicLoader (bootloader/monitor) Power-up 

The Fire Engine is shipped with a version of the LogicLoader (bootloader/monitor) programmed 
into the Boot Flash device at an offset of 0x40000.   
 

Accessing LogicLoader 

 
Interface to LogicLoader via a terminal emulation program connected via a null-modem serial 
cable to the “Terminal” port of Fire Engine (Serial Port on the CDK).  If you did not change the 
baud rate, as suggested in step 5 of the previous section, use the following default terminal 
settings: 19200 baud, 8-data-bits, 1-stop-bit, no-parity, and no-flow-control.

 

 

Start a terminal program on the host computer (i.e. Tera Term, HyperTerminal, etc.).  

Connect a serial cable to the host computer and to the Serial Port on the CDK.  

Apply power to the Fire Engine.  By default dBUG will appear. 

If you have not already done so, change the baud rate of dBUG to 115200 by following 
the steps outlined in Section 4.2.1, Step 5 (above). 

At the dBUG prompt enter the command ‘go ff840000’. Press Enter.
