TMS320F280033: Large code : can load code but can't debug nor run

Adrien Thurin

Part Number: TMS320F280033

Tool/software:

Hi,

Following this question, answered by Marlyn Rosales Castaneda20 (thanks again !), I have been able to load in flash some hardware test code, and run it fine.

However, when I migrated my eval board (F280039C) code application code to the actual application board, the code didn't fit with the new .cmd file. So I tried to concatenate some memory sections, in order to make it fit. In the end, it all fits, the linker is happy. I launch the debug session, press play ... and the core halts. Nothing happens, it is just always halted. I thought it might be a debug issue, so I reset the target, and tried to discuss with it on the CAN bus, but no message in or out. Which makes me think the code is loaded but not running.

Here is the original cmd file provided by Marlyn Rosales Castaneda20

Any idea where the issue might be ?

Thanks in advance,

Hi Adrien,

I don't see any major issue in your linker cmd file. So, with the modified cmd file, where you able to run the application in the eval board?

Also it would be good to give the correct length instead of using '+' and '*' operator in the linker file.

Please try out the modified linker cmd file and try out in the eval board and check if you are facing any issues.

Thanks

Hi Aswin,

I didn't test the modified cmd on the eval board Friday, only on the actual application. That being said, I just did, and it doesn't work either. Symptoms are the same, program is loaded but doesn't run. Even when removing '+' and '*' operators in the linker file.

Any idea what could be the issue ?

Thanks in advance,

Adrien

Hi Adrien,

Did you get any issues/errors while building the application? Lets confirm if the new cmd file is building fine and is getting build properly without any errors.

Is it possible to share the application for debug?

Thanks

Aswin

Hi Aswin,

No, no issue / error while building. Moreover, it worked fine on the launchpad with the default cmd file for C280039. The only thing that changed between something that works and something that doesn't is the cmd file.

How can I share the application privately ?

Thanks,

Adrien

Hi Adrien,

I meant whether you were able to run your application on the launchpad using the updated linker cmd file?

You can zip the application and share in this E2E.

Thanks

Hi Aswin,

The application runs on the generic linker file on the launchpad.

Lightweight codes for hardware testing run on the lauchpad with the TI-modified linker file for F280033

Full application code does NOT run on the lauchnpad with the manually modified linker file (based on the TI-modified linker file for F280033).

I have tried to upload the application code here, but it is accessible to everyone and not just TI employees, which is not acceptable. Is there another way to provide you with the code ?

Best regards,

Adrien
