Porting MQX

[Dekabrist]

Is the port MQX for MCF5271?

[Dekabrist]

I send request for evaluation package. Is the Fresscale have porting guide for MQX like for uCOS (Micrium)?

[LeoPucci]

You should check on the Mqx reference manual, the io user guide and on the mqx user guide.

Inside examples folder, you should find examples that will help you more to understand about Freescale MQX. 

Unfortunately, seems to me that this documentation would not help you.

I think that this embedded acces E. Package might be an old release of Mqx after Freescale.

So you should see with them about support, documentation and porting guide. But I'll be here if you need some help.

In fact, I have to warn you. As this might be an old release, it will have several design changes between E.Acess Mqx and Freescale one.

I'm openning a techincal request to see if Freescale Mqx will have support for you processor. So you could design and I could assure you support and documentation.

I'll post it here as soon as I receive the answer.

Regards,

Pucci.

An up to date version of MQX is available for the MCF5271 from Embedded Access. However in accordance with our agreement with Freescale a license fee does apply to this release. Please keep in mind that the license agreement associated with the downloadable version of MQX does not permit porting to other processors that the release does not already support. This is because the supported processors have the software license costs built into the silicon price which isn't the case for older devices.

Let's see if I understood.

So, for old products, the MQX to be used is from Embedded Access?

And what about licensing for use?

Do you know something about Viragelogic MQX?

It's the same MQX licensed for several companies?

[Doug_EmbeddedAc]

Yes correct. With our agreement with Freescale the MQX platform can be licensed from Embedded Access for all legacy ColdFire processors, Power Architecture processors, and i.MX processors. The Freescale MQX platform was originally based on the virage logic MQX so it has the benefit of over 20 years of field proven robustness but it has been enhanced and much more aggressively priced.

The last one!! Hehe.

But what about this Mqx with several flavors? So to use Mqx for some old MCU, I have to use it from Embedded Access. And support? Documentation?

[Doug_EmbeddedAc]

The version of MQX from Embedded Access is the full platform including all documentation - just like the Freescale version has but you have a license to use it for a device not supported by the Freescale version. Embedded Access provides different levels of technical support ( http://mqx.com/support.html  ) and optional add-on components.

Incidently the MQX 3.5.1 has a special patch for new CPU MPC5125. Is this CPU covered under Free MQX license if one wants to use it in an end product?

On the Embedded Acces site, the MCF527X is included in the list of supported processors.

Although, on Freescale.com/mqx, it is not listed.

Seems to me that the core is supported. But is not optimized by Freescale with examples and sample projects.

Maybe this link will help you. Try asking for evaluation. The 5271 is listed there. Perhaps they have an example or 5271 core folders targeted for CW.

Please post a feedback here about it when you receive some answer.

Regards,

Pucci.
