3 TARGET PROGRAM AND DEBUGGING

3 Target Program and Debugging

This chapter describes precautions for debugging using the debug monitor.

3.1 Notes for Creating Target Programs

Follow the instructions below when creating the target program to be debugged:

•Since the debug monitor uses the debugging exception of the CPU, addresses 0x0 to 0xF of the built-in RAM area are used as the vector and stack for processing debugging exceptions. Therefore, the target program cannot use this area. Furthermore, do not use addresses 0x10 to 0x2F.

•When debugging the target program by writing in the RAM or Flash memory on the target board, map the program to that address.

•The debug monitor does not allow forced break functions such as key breaks. Forced break functions should be made in the target program using a key input interrupt or an NMI input. Setting a hardware PC break in the interrupt processing routine makes it possible to execute a forced break.

3.2 Parameter File for Debugging

A debug-parameter file is required to start the debugger. Create the file according to the memory configuration of the target system. When using the debug monitor, the debugger ignores all the settings for the ICE emulation memory.

When using a Flash memory, specify it as a RAM.

Example: "dmt33004\sample\33104_m.par"
