Porting M68040 assembly code to MCF54452 Coldfire using CodeWarrior Coldfire Architecture Version 7.2

johnchan — Mon, 25 Jul 2016 20:15:45 GMT

I am trying to port M68040 assembly code to run on MCF54452 Coldfire processor.

I am currently using the CodeWarrior Coldfire Achitecture V7.2. The original M68040 assembly

code was compiled with Microtec. Are there any examples or documents showing how to set up

a CodeWarrior project to run the assembler on the M68040 assembly code?

I know there will be assembler errors because not all instructions are supported in the Coldfire.

However, I need information on how to setup the CodeWarrior project to start assemble the code.

Thank you in advance.

Hi John,

I think that the cleanest way to migrate the project is to create a new project in CodeWarrior 7.2 for the MCF54452 MCU and start writing your application, you can use following documents as reference to help with the code migration:

http://www.microapl.com/Porting/ColdFire/index.html

I would also recommend using CodeWarrior 10.6.4 which is the newest version:

CodeWarrior for Microcontrollers-Eclipse IDE|NXP

Hope it helps!

Best Regards,
