Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi all,

we use the Am243xLP board and the CCS.

Our first evaluation should look like this:

CPU0_Core0 is used for our real-time and a freertos-
CPU0_Core1 is used for the fieldbus.

I have set up such a project:

CPU0_Core0:

Timer Irq for realtime
Freertos to evaluate the notifications that come from the CPU0_Core1.

CPU0_Core1:

Freertos -> send Notify
The M4 CPU just says "hello".

So my project consists of the 3 projects for the 3 CPU's and the

system project "MultiCore_R5".

The projekt works fine.

And here is my question:

I would like to swap my empty_am243x-lp-r5fss0-1_freertos (CPU0_Core1)

project with the example cia401demo_r5fss0-0 (CPU0_Core0).

I dont know exactly how I should handle the sysConfig file. Can someone show me the right way?

Thank you.

Best regards,

Alexander

Hello Alexander,

Thanks for your query.

You can do so by modifying the empty example of R5F0-1 core. Add the sysconfig and source code related changes from R5F0-0 core to empty R5F0-1 core.

Make sure you have done the proper resource allocation for R5F0-1 core. Please refer RESOURCE_ALLOCATION_GUIDE for details.

Hello Tushar,

Thanks for the reply.

Then I'll take a look at the Resoure_Allocation_Guide.

Hello Tushar,

i read the resource allocation document for more information. Thank you very much for that.

But these resource configurations refer to the assignment of the hardware. I don't want to change that, I continue to use the Launchpad board.

Unfortunately, I couldn't see what exactly the steps are that I have to do for switching from R5F0_0 core to R5F0_1 core.

You said:

„Add the sysconfig and source code related changes from R5F0-0 core to empty R5F0-1 core.“

Can you explain to me exactly what changes have to be made to change the example from the R5F0_0 core to the R5F0_1?

It is similar to create a project with custom changes done on the empty project provided in the SDK.

Import the empty project for R5F0-1 core and copy all the code from R5F0-0 core. Add the peripherals/modules in the example.syscfg file as you did for R5F0-0 core example.

Please let us know if you face any issues.

Hallo Tushar

Thank you for your really quick response.

Ok, I have to import the empty project for the R5F0_1 core. Then I copy the code into my system project, and add the sysconfig.

But there is one practical question remaining.

The sources of the cia402 demo project will be created as a link in the ccs project.

How can I import the links for the sources and the paths/variable settings from the source project into my empty project.

Unfortunately, Import Settings does not work. No settings to import are displayed.

What can I do?

Regards,

Alexander

Hi Alexandar,

To add the files in the existing project, please follow below steps.

Right click on the project and select Add files option, navigate to the path of file.

Select the option Link to Files and check the option Create Link locations relative to PROJECT_LOC.

Please refer below image.

Hi Tushar

It's great that you answer my questions so diligently.

I still have a question of understanding:

Why don't we just change the context parameter for the sysconfig rule

from r5fss0-0 to r5fss0-1 to make the project run on the other cpu?

It can be done, but there is not a single change that you can do and build the example.

You will need to change makefiles, projectspecs or may be compiler flags also(this setting will change drastically if the core architecture change, like moving from R5F to M4F). It will be tedious task to do all. That's why the simple task is to take an empty example and copy all your code onto it.

Hope the above clarifies.
