Porting project to MQX

abelebarbieri — Fri, 19 Apr 2013 12:23:03 GMT

I have a Codewarrior 10.3 project developed also using Processor Expert.

There is a possibility to make it run under MQX without the need to remake the project? it's possible to trasform this project in one or more MQX tasks?

Please, help me!

Thanks. Abele

Hi Abele,

if you have developed your project on Kinetis derivative which is supported by MQX than it is possible. You can export settings of PEx components in your baremetal application using

File -> Export -> Processor Expert -> Export Component Settings, select components you would like to be integrated in MQX BSP and save to some MyComponents.pef file
Open BSP project which you want to import your component settings to and File -> Import -> Processor Expert -> Component Settings to Project
Generate code and resolve possible component conflicts.
Rebuild libraries.
Create application using your PEx components.
Check MQX examples to see howto create task (hello,...) and task entry into task template list
Add your task which handles the PEx components.
Copy code from your baremetal application into new task
Copy events from your baremetal Events.c into some application C file
Build application and resolve build issues.
Debug runtime issues.

This is just simple workflow as I do not know any details about your application. Transfering baremetal code into RTOS is little bit tricky. The description above do not take care about application optimization and splitting baremetal superloop into tasks and using RTOS synchronization objects for better performance as this is application specific.

Hi Petr

I made a few tests with Processor Expert included in BSP. I think I found an issue related to Logical Device Driver BitIO_LDD and BitsIO_LDD. If I added one of these component, PE generates the files .s and .h for the build, but when you build the BSP library it does not create the object referred, and then produces error.

I think that there is a trouble in CW10.3 using MQX and Processor Expert. I attach Codewarrior screenshot to best understand.
