Thanks, Eric!

This was increadably helpful. Would have been even more helpful if I had it a while ago -but I still found usefulness in memory saving stuff, etc.

I think this post should be made sticky, to stay on top in the forum.

Cheers,

I have downloaded the stack example AN3470SW.zip and try to compile directly with CodeWarrior 6.2

I get a lot of errors like:

            - Instruction not legal for current target processor(s)

            ......

            - internal compiler error (report to cw_bug@freescale.com)

            while executing in file ‘PCodeAssembly.c’ line: 626

            (compiling ‘_printk_mknumstr’ in ‘printf.c’)

            - the file ‘Int_hnadlers.h’ cannot be opened

            Int_handlers.c line 12 #include “Int_handlers.h”
            .
            .
            .
            Etc
 

I suppose that the problem is that CodeWarrior 6.2 doesn’t support the MCF5223x microcontrollers. 

Can you tell me please if this is true? 

If is true, what version I must use?

There is some example to run this code on MCF5208EVB or the steps to follow?

Thanks,

Jack

Hi man...

Codewarrior 6.x are only for coldfire v1 microcontrollers... For the V2 family you must use Codewarrior 7.x or the new Codewarrior 10.x (eclipse based) that attends coldfire v1,v2,v3 and v4.

Best reguards...

 Can I use this code as part of my product´s project? I already read the 2 pdf´s and i see you wrote it´s intended to help coldfire customers to develop their products. So i understand i can use it and modify it as i want to incorporate it into my products using MCF52235CAL60. It´s very important to know this, because i already made a lot of modifications including POST method, Basic Authentication and so on...
