AM2631: How to run Beckhoff SSC EtherCAT application from C++ main application

Part Number: AM2631
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi,

I successfully ran the EtherCAT SubDevice Beckhoff SSC Demo example.

Now, I would like to convert the C application to a C++ one. To start, I changed the main.c file from the Beckhoff example to main.cpp, but that doesn’t seem to be enough. I’m using CCS20 and the latest SysConfig, letting the makefiles be automatically generated rather than writing them manually.

The application doesn’t compile if System_init(); and Board_init(); along with their include files are present in the project. I noticed that the "Hello World C++" example has some special configuration in SysConfig, such as "DPL CFG." Can you explain what this is?

Is there a guide for starting a C++ application for the AM263x in CCS20 from scratch?

Thank you in advance for your help!

Best regards,

Chris

Hi Chris,

Apologies for long delay in response here.

The recommendation from TI is to use the hello world/empty project as reference to start your own project instead of creating one.

Import the project and then add the respective files for your use case.

Let me know if you still need some help with this thread.

Thanks for your answer.

I like the approach from the other side, but I could need some guidance here:

When just adding the Industrial Comm. SDK it will not compile anymore.

Is there any tutorial I could follow?

Cheers,

Chris

Hi Chris,

We do not have such a tutorial on creating a for mcu plus sdk from scratch.

But we do not recommend creating a project for mcu plus sdk. As the projects provided in sdk comes with all dependencies correctly set.

may I know why do you need to do start from scratch?

Hi Nilabh,

I thought starting from scratch is my only option. I just need a running EtherCAT application started out of a C++ main. This because my legacy code is all in C++.

The mcu+ sdk is linked from the default TI "hello world" C++ project :).

Hi Chris,

it is relatively easier to convert the hello world c++ project to ethercat example than creating one from scratch.

i will create a request for c++ reference project addition to Industrial comms sdk. I understand the issue now.

Let me know if you need any further help.
