Hi,

When running the fast current loop project (fcl_f2837x_tmdxiddk) in C2000Ware_MotorControl_SDK_3_00_00_00 tmdxiddk379d, I get the following warning:

#10462-D Symbol, "Q_cla", referenced in "./sources/fcl_cpu_code.obj", assumes that data is blocked but is accessing non-blocked data in "./sources/fcl_cla_code.obj". Runtime failures may result.

Can you advise why this is happening?

Please upgrade the C2000 code generation tool that can be downloaded here.

Sorry. We can't repeat the issue as you mentioned above, could you please provide more information about your question?

1. What versions of the CCS and the code generation too did you use?

2. What build settings did you implement? Any changed or setting in "fcl_f2837x_tmdxiddk_settings.h", or please post the file for our reference.

3. Did you change anything when you imported the project into CCS?

You might try to clean the project first and re-build it again in CCS.

Any updates? It's been about 2 weeks since we heard from you, so I am assuming you no longer need clarification for your question that will be marking this thread as closed. You can reply with a post or create a new thread if you have any further questions on this topic. Thanks.

Anthony,

For the new diagnostic 10462 that you encountered, the best practice is to define the shared data variables in the C28x code, and not the CLA code. For more details, please search the C28x compiler manual for the sub-chapter titled Variables and Data Types.

Also, below e2e post has more background on the new warning:

Thanks. I've started evaluating a different drive project in the FCL examples.
