Quick Start

Starting up the debugger is done as follows:

1.

Select the device prompt B (BDM debugger) and reset TRACE32.

The device prompt 

B::

 is normally already selected in the 

TRACE32 command line

. If this is not the 

case enter 

B::

 to set the correct device prompt. The 

RESet

 command is only necessary if you do not 

start directly after booting the TRACE32 development tool.

2.

Specify the CPU specific settings. 

This command selects the CPU type. 

3.

Inform the debugger about cashable address range (FLASH/EEPROM)..

This is important to speed up the T32 GUI responsiveness. The specified address range will be 
accesses only once after a break, thus avoiding unnecessary memory accesses.

4.

Reset the target and enter debug mode.

This command resets the CPU on the target, enables On-Chip-Debug Mode and issues a breakpoint 
right after the reset interrupt routine.The CPU stops executing any instruction, and the user is able to 
download the code and test. After this command is executed, it is possible to access memory and 
registers.
