How to convert MCU MC9S08 CW6.3 code to CW11

One of the customer has production code based on CW6.3 on MCU MC9S08 and now he wants to move it to CW11. Let us know how to do it with minimal effort. The old code in CW6.3 is developed using PE.

hi Kamil Kamil

There is no CodeWarrior importor that can import CW6.3 project to CW11 directly.

We suggest you create a new processor expert project under CW11 then add source code part by part.

we can also refer

Have a great day,
Jun Zhang

Hello ZhangJennie‌, Thanks for quick reply.

I created new project with PE (processor Expert) and added other project files to new project.

Now i am facing two issues.

1. I deleted "main.c" file generated by project vizard and added old project "main.c" files and in PE choosen dont generate code. but still whenever i try to build code it generates its own "main.c" files, so we get error of duplication main function.

2. Some time it done generate its own "main.c" file when build but getting error "Out of allocation space in segment RAM at address 0x241" though this is production code and had no error.

With Regards

Kamil

Hi Kamil

as we discussed, CW11 will generate more code size and for .bss and .common which eats up more RAM size.

My suggestion is to reduce stack size to save RAM space.

Have a great day,
