Nothing is attached. What errors do you get? Did you add any .h files?

Sorry! I think something went wrong while uploading. please find the documents below. Thank you for your prompt response.

I am unable to import

You problem description is not specific enough. You mean CCS does not "see" the source code file? What error messages are you getting?

Rama krishna said:

how to integrate the code generated through Matlab simulink embedded C  coder into CCS theia or CCS.

In general, if your primary focus is developing code in Simulink my advice is for you to use "MATLAB Simulink Embedded Coder Hardware Support package for AM26x". This package also supports AM263PX. You can request access at this link: ti.com/secureresources/AM26X-SL-EC

Hi Kier,

I am currently using the latest "MATLAB Simulink Embedded Coder Hardware Support package for AM26x V24.2.0.12," which is the latest version available in MATLAB, but I couldn't locate it on the TI website. Could you let me know when the updated version will be released on the TI website?

Additionally, when trying to import the package, the "Finish" option is disabled, and I am unable to proceed. To work around this, I manually added all the .c and .h files to an empty project example in the workspace. I cleared the errors by excluding the initialization files, but the drivers are being referenced in those files. After debugging, I noticed that there is no response from the board.

Thank you for your help!

OK, thank you. It looks like TI have now made this package available to Mathworks. Last year it was only available by special request to TI directly. That version was 24.1. Therefore, I think you have the latest version from Mathworks.

Rama krishna said:

You mean when trying to import the package into Simulink? It's not clear. Pls post screenshots of the problem.

Sorry for the confusion.
when I am trying to import the generated code into CCS theia or CCS.
I am attaching a video of it.
and i figured out that the initialization files are causing the issues so i excluded them and run the remaining

4 Examples.pdf

Rama krishna said:

causing the issues

But it's not clear what the issue is. I doubt that excluding any files is going to fix whatever the problem is.

In any case, the main advantage of the Simulink HSP is that you don't have to worry about managing the project in CCS. Simulink does this work for you.

Can you first confirm that the examples work?. See attached.

yes they do work,

but these examples are for am263x in need to change the hardware settings for am263Px control card (I have tries GPIO led and UART echo)

Reason why I went to CCS is because I cannot access IO expander through matlab simulink

I am not sure how to run both subsystems R5FSS0 and R5FSS1 through simulink and I want to inegrate some part of the code which is developed through matlab into the code which is being developed by my team through CCS

OK, I understand why you want to use CCS now.

Unless Simulink generates a .project and .cproject files, you can't really import a project to CCS, only add source files to an existing project.

Does Simulink generate a .project / .cproject file?

Hi, Kier

Sorry that I am on vacation and didn't get a chance to access my pc

Does Simulink generate a .project / .cproject file?
It generates .c and .h files which I have linked and posted above and yes I have tried adding source files to an existing example but it didn't work.

So, I am trying to add .c and .h files one by one and trying to clear the errors. The main challenges I’m facing involve reinitialization of timers and pins because they are being configured in both example.sysconfig and in the code generated by MATLAB. Additionally, driver initialization in the example projects is spread across different .c files, which creates conflicts with the MATLAB-generated code.

And this is the reason why I've reached out for help.

Thank you.

Hi,

Thank you for the suggestion. I have already tried starting with an example from the MCU+ SDK, like taking an example, and adding the .c and .h files as Kier mentioned. Unfortunately, this approach didn’t work as expected.

The main challenges I’m facing involve reinitialization of timers and pins because they are being configured in both example.sysconfig and in the code generated by MATLAB. Additionally, driver initialization in the example projects is spread across different .c files, which creates conflicts with the MATLAB-generated code.

As I try to resolve these issues, It feels like coding all over again and missing the advantage of code generated through matlab, but I would appreciate any further guidance to streamline this process.

Thank you for your help!

Best regards,
Rama Krishna

Sorry but I'm going to have to bail on this question. It's simply not specific enough. It sounds like you need the assistance of a software engineer in your organisation who is familiar with basic/platform software compilation and register level debugging.
