Using MXQ with Processor Expert

Hello,

 

I am trying to work with MQX 3.7 and Processor Expert on CodeWarrior 10.1 SE.

First question: Should I create a MQX project or a Processor Expert project?

When using a MQX project the Processor Expert is not working. It says this is not a Processor Expert project and I should select an other one.

When using a Processor Expert project I can add MXQ as a module but then I am not able to compile the project because of missing MQX includes.

Has someone a solution for that problem?

Look at the following file: C:\Program Files\Freescale\Freescale MQX 3.7\doc\FSL_MQX_3_7_in_CW_10_1.pdf 

PE section starts at page 89.

 

That should get you up and going with PE and MQX!

hello,

 

I also need help.

 

i tried to follow the steps in this document C:\Program Files\Freescale\Freescale MQX 3.8\doc\tools\cw\FSL_MQX_in_CW_10_x.pdf

 

I am doing the procedures on the Section: CW10.x, MQX and Processor Expert.

 

When I try to debug my program on the TWR-K60N512, it say "Low Power Wait", when I try to pause the program, it always stay in the dispatch.s. I put a breakpoint on the tasks and neither of them are executed.

 

Hoping for your help. Thanks in advance.

Thanks for that tip.

Now I know that it is possible to create a project with MQX and PE but how do I create my own project or do I have to use and modify that demo project?

Processor Expert is integrated with BSP. PEx project is a part of BSP library. If you open the existing BSP project which is based on PEx (project suffix _pe) in CW you will see Processor Expert folder in the project panel. This is the right place to add additional PEx components or make changes in component settings. When you build the BSP library all necessary files are copied into {MQX}\lib{BSP name} directory (e.g. twrk60n512.cw10). There are also C libraries (e.g. bsp_twrk60n512_d.a). This library is added by the project wizard into your newly created MQX application. MQX 3.7 contains two BSPs based on PEx. One for TWR-MK40 and the second one for TWR-MK60. Just note that PEx based BSP and non PEx based BSP uses the same name for BSP library (.a file) and directory in {MQX}\lib. It means you can easily build a BSP with/without PEx without modifying of your application (library paths are the same).

 

Modifying of the existing PEx demo applications is the best way how to start with PEx-MQX. These demos you can find in and directory in {MQX}\demo\pe_demo. Note that you should build BSP with PEx first ...

 

 

If you need an additional assistance, don't hesitate to contact me ...

Unfortunately not. Processor Expert is tightly integrated with MQX for Kinetis platform only not for other platforms, e.g. ColdFire V1-V4. On other platforms, many customers use PEx generated drivers directly in MQX application. There is necessary to correctly install interrupt service routines via MQX API yourself in the application before initialization of PEx driver. This is not convenient way but it works. You can find an example how to install PEx interrupt service routines in MQX on MQX forum.
