InterNiche’s ColdFire TCP/IP Stack on MCF52233

mark_30 — Wed, 03 Jun 2015 09:50:11 GMT

Hi,
To retrofit old boards, I have to start a new project with a MCF52233.

Is possible to use "InterNiche’s ColdFire TCP/IP Stack"? Which CodeWarrior version I have to use?

I try with CodeWarrior Special Edition Classic, present on Freescale site:

http://cache.freescale.com/lgfiles/devsuites/HC08/CW_MCU_V6_3_SE.exe?WT_TYPE=IDE%20-%20Debug,%20Compile%20and%20Build%20…

but apparentely this version is too old to compile this stack.

You need CodeWarrior 7.0, to be able to compile and use it. CodeWarrior 7.1 might work, but I'm not sure since I haven't tested it. I know for a fact 7.2 and later won't work though.

Hi dyspn,

thanx for your reply.

Now, the problem is where to find this release.
From freescale website I able to buy/evaluate only 7.2 version.

If I buy/evaluate 7.2 licence, can I downgrade to 7.0 and work whit it?

You should be able to buy a new copy of InterNiche's stack that works on the current versions of CW.

Small and Portable TCP/IP Protocol Stack Source Code for Embedded Devices: InterNiche Technologies

If the budget won't stretch to that, but will pay you to spend a lot of time modifying code, then read TN268, which details how to convert pre-7.1 projects to 7.2 and after. They changed the ABI (which registers pass parameters and so forth). This really only affects code with assembly source code files.

Also type "TN268" into the Search Box and read up about what others have done when handed this problem.

> CodeWarrior Special Edition Classic

You know that's code-size limited to 128k? Will your project fit? You could even use MCF52230/1/2 (128k) parts with that limitation.

Hi Mark,

A couple of years ago I modified Coldfire Lite to compile on Codewarrior 7.2.2 and included some bug fixes at the same time.

You can find my version in attachment. 5223x and 5225x only :smileyhappy:

Regards - Marc

5 years after still using your sofware.

Thanks Marc, you are a code beast.

It's a pitty that the MCF52259 don't evolve ....
