AM2434: AM2434: Code Composer Studio: FreeRTOS ROV exception

Part Number: AM2434
Other Parts Discussed in Thread: SYSCONFIG

Hello,

I'd like to use your Runtime Object View (ROV) in Eclipse-based Code Composer Studion (CCS v12.8.1) to monitor OS Kernel (FreeRTOS) Task Instances. However, when dynamic memory is involved - required by functions such as OSAL_SCHED_startTask(***) (Industrial Comm SDK) - ROV fails when trying to inspect the task.

After investigation, I found that the issue is related to the memory type being set as NOLOAD, which dynamic memory typically uses. If the memory type is set to LOAD, the problem does not occur.

Could you please advise on how to resolve this issue? Is there a recommended configuration or workaround for using ROV with dynamic memory regions marked as NOLOAD?

Thank you for your support.

Best regards,
Vit Triska

Hi Vit,

Please tell which version of SDK are you using? Is it the default example provided with SDK?

Hello,

This is an SDK-independent issue (currently tested with Industrial Communication SDK 11.00.00.13).

You can easily reproduce it using the bundled Profinet demo example. As soon as the section containing dynamic memory is configured not to be initialized at startup (i.e., memory type changed from LOAD to NOLOAD), the ROV tool stops functioning when inspecting FreeRTOS tasks (but demo still works correctly as expected).

Could you please confirm if this is a known limitation or provide guidance on how to make ROV work with NOLOAD memory sections? Is there any recommended workaround or configuration adjustment?

Thank you for your assistance.

Best regards,

Hi Tushar,

Yes, I’ve checked, and the map file is attached for your reference.
Could you confirm if you are able to reproduce this issue on your side as well?
(A Profinet "am243x-evm" example with the NOLOAD type option in Sysconfig tool.)

Regards,

Vit
