TMS320C6747: Code Composer Studio 20 Support for C6000 devices

Hello,

Tim Janßen said:

Is our device supported by the new Theia IDE-based CCS?

Yes. Project build and debug support is there.

Tim Janßen said:

Upon investigation, we noticed that the folder c6747 is missing in the path ccs2011\ccs\ccs_base\common\Modules\

I would expect this to be in ccs\ccs_base\common\targetdb\Modules. But I do not see any such folder. I also do not see it in my CCS 10.4.0 installation either. I'm wondering if you installed some additional CSP in your older CCS installation. Can you provide the ccxml file you used in the earlier version?

Tim Janßen said:

However, we now encounter a new error:

I assume your *.out file is relative big and you are running into this known issue:

https://sir.ext.ti.com/jira/browse/EXT_EP-12247

It is fixed in our current latest CCS 20.2.0 release.

Thanks

Hi ki,

Thanks a lot for your quick response!

I've attached the .ccxml file we used in the earlier CCS version below. The setup was a fresh installation, and during the installation of CCS 10, C6000 device support was explicitly selected. The following components were installed:

• C6000 Compiler versions 8.3.5 and 8.3.13
• TI-RTOS version 6.76.02.02
• UIA version 2.30.01.02
• XDCtools version 3.51.03.28

It's possible that the missing c6747 folder originated from an additional CSP that was included in that setup, although we didn’t install anything beyond the components listed above.

Regarding the new error: thank you for pointing out the known issue with large .out files (EXT_EP-12247). We'll proceed with updating to CCS 20.2.0 and check if that resolves the problem.

Here is the .ccxml file content:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

Thanks. The schema may have changed a bit for that device xml. When I create a similar (working) ccxml for c6747 in CCS 20, this is what it looks like:

Hi Ki,

Thanks again for your support.

I’ve freshly reinstalled Code Composer Studio version 20.2.0.12, leaving all installation options at their default settings. Unfortunately, when I try to create a new C6000 project, I can’t find any C6000 boards or devices listed.

I also tried using the customized .ccxml file you provided, but unfortunately, the same error message still appears:

"Cannot read System Setup data from XML file [...]"

Additionally, I noticed that the “Test Connection(s)” button is greyed out in the ccxml file view. This button was working in our previous CCS 20 installation.

It seems like C6000 support is either missing or only partially included in this version of CCS 20, which is quite disappointing for us. We were really hoping to continue working in the Theia-based environment.

Any further suggestions would be greatly appreciated.

Best regards,
Tim

Please see: https://software-dl.ti.com/ccs/esd/documents/users_guide_ccs/ccs_faqs.html#i-get-a-no-example-projects-found-please-change-your-filter-message-when-looking-for-examples-for-my-selected-device-does-that-mean-that-my-device-is-not-supported-by-code-composer-studio

For older devices like C6747, there may not even be an option for it in the list. But that doesn't mean CCS doesn't support it. Only that you can't browse for examples or create a new project using the CCS project wizard.

Instead of using mine, please try creating a new one from scratch and using that.

I checked my 20.2.0 installation and the button is there and it seems to work:

Make sure the ccxml file is saved and there are no errors with it.

Admittedly, the support is not as good for older devices like C6747. CCS 20 relies on proper device support and SDKs for the device in Resource Explorer which is a known gap for your device. However, the core project import/build and debug should work in CCS 20.

Thanks

Hi Ki,

Thanks again for your response.

I’ve now repeated the entire installation process on two freshly set up systems (both running newly installed Windows 11), and I’m consistently seeing the same result: the folder
C:\ti\ccs2020\ccs\ccs_base\common\targetdb\Modules\c674x
is missing after installation. As a result:

• The error message mentioned earlier appears when I try to start a debug session
• The “Test Connection” feature cannot verify the target connection
• The debug settings under Project → Properties → Debug cannot be displayed (error messages appear)
• The launch.json file is not generated correctly

However, if I manually copy the missing folder from a CCS 10.4 installation, everything works as expected. It seems like the C674x support is not included in the installation by default. Strange that it was present on your system after installation.

So it’s not an issue with the *.ccxml file—it doesn’t matter whether I use a new one, the existing one, or even the one you provided.

Best regards,
Tim

Which components did you select when you installed CCS?

My selected everything for my install. I assume you did not. I suspect wherever you selected is missing full c674x support.

Hi Ki,
I selected the following during installation:

- C2000 real-time microcontrollers
- C6000 Power-Optimized DSP
- MSP430 microcontrollers
- TM4C12x Arm Cortex--M4F MCUs

Best regards,
Tim
