Confirm whether CodeWarrior Development Tools v11.0 includes emulator functionality

GAO123 — Mon, 23 Jun 2025 02:01:33 GMT

Dear NXP Technical Support Team,

I would like to confirm whether CodeWarrior Development Tools v11.0 (specifically for ColdFire/MCF547x series) includes emulator functionality that supports the following workflow:

Import Binary/HEX Files:
- Directly load compiled *.bin or *.hex files into the emulator.
Disassembly to Assembly Code:
- Automatically convert the binary/HEX content into assembly code (ColdFire V4e instruction set).
Debugging Features:
- If supported, does the emulator allow:
  - Step-through execution (single-step, breakpoints)?
  - Register/memory inspection?
  - Real-time modification of code/data?

Hi @GAO123

CW 11 doesn't have emulator functionality.

The S19 and HEX files contain optimized binary code for burning, not the original assembly code. When loading the image in the debugger, we can view the disassembled code, but stepping through it is limited because it doesn’t match the original source.

Thanks,

Jun Zhang

Thank you.
Which CodeWarrior version can directly support importing bin/hex files and disassembling them through the built-in disassembly view (debug mode)?

Based on MCF5474 microcontroller.

Hi @GAO123

We can use decoder.exe under CW11 to generate disassembly code. You can search out decoder.exe under CW11 install folder.

Set Options as : -A -Proc=M68k

Drag your S19 file to the decoder, and you will see a *.lst file generated. Then, scroll down and you will see the disassembly generated in the lst file, for example as follows.

Have a nice day,

Thank you for your reply.
The decoder.exe in the CW11 installation directory cannot be set to Options as: - A - Pro=M68k, there is no such option. Additionally,
Does M68k fully include the instruction set of ColdFire V4e core kernel. Can it be simulated and debugged.

Hi,

I'm not aware of any way to directly disassemble s-record or binary back into CF disassembly in CodeWarrior.

CF Linker (c:\Freescale\CW MCU v11.1\MCU\ColdFire_Tools\Command_Line_Tools>mwldmcf.exe -help) supports disasembly listing generation only from executable file (.elf)

Anyway you can definitely load/import the binary file into the real MCU (sorry ColdFire emulation/simulator is not supported by CodeWarrior) using debug probe and let debugger to interpret the code at the loaded address.

Hope it helps.
