Hi i am a new user of GNU toolchain. I have been working on Renesas Tool chain from past 3 yrs now ... Wish to work on KPIT GNU toolchain for M16C... Can you help me in understanding the debug enviornment... Does GNU Toolchain have Simulator ? How to use it ? Because i don't see any Simulator Session in HEW IDE after creating the project. After creating a project how to use the debugging feature in GNU Tools ... i tried with the m32c-elf-gdb.exe but, what file needs to be given as input to GDB ? I can find *.x and *.o files created after build how to proceed further for debug ... waiting for a reply.

I am having HEW4 on WinXP Platform with GNUM16CM32Cv0501 and GNUM16CM32Cv0601

The new HEW4 integrates in-circuit Debugging. These features can
be used to verify that the program you have developed works exactly
as you intended, or, when it does not, to find out why.

Breakpoints can be set in HEW to stop the program at certain points
and verify registers, variables in memory, etc. The number of
breakpoints will vary from MCU to MCU. I believe for the MCU that you have there are 6.

HEW allows �step� execution in your program, which means the
program executes on a per-line basis (whether in source level or
machine-code level). Various windows in HEW allow you to see
register values and memory locations.

As the debugging features of HEW are fully integrated with the IDE,
editing, compiling and debugging can be done in the same window.

In order to run the debugger you have to Compile the program and
then launch a debugging session by clicking on the KD30 icon.
