TMS320F28069: CLA Task Debugging - Does not contain frame information

Mashrur ALam

Part Number: TMS320F28069

I have a very similar question to CLA does not contain frame information - Code Composer Studio forum - Code Composer Studio - TI E2E support forums

I am able to successfully run and debug the sample c28069blink_cla model provided by Mathworks. However when I take the contents of the sample model and paste them into my simulink model issues start arising. The CLA behaviour is not correct so I am trying to use CCS to debug the task.

In order to attach the debugger to the CLA I did the below. I then did "Load Symbols" then pointed to my .out file.

I have set up two breakpoints in my CLA Task however these breakpoints are never reached. Instead I see a 'Cla1Task1 does not contain frame information" notice. Similarly even though the debugger states the CLA_0 core is suspended I can see with my scope that GPIO 34 is toggling so I know that Cla1Task1 is being called and excecuted even though my breakpoints are not being hit.

When I click on "Resume (F8)" to trying to move the debugger along I get:

CLA_0: Can't Run Target CPU: (Error -2060 @ 0x0) Requested operation cannot be done while device is running. Halt the device, and retry the operation. (Emulation package 9.3.0.00032)

What could be causing this?

thanks,

Hi Mashrur,

Can you please provide a snapshot of the disassembly view of the CLA when it's halted. That should provide a clearer picture of where the CLA is halted.

Thanks,

Ashwini

Hi Mashrur,

From looking at the disassembly window it looks like this location does not have valid code - this is indicated by the .word lines in the disassembly which indicates invalid opcode. Please check to make sure the application is getting compiled correctly for the CLA - memories mapped to CLA in linker command file are being assigned by the C28 to the CLA in the code.

Thanks,

Ashwini

Hi Mashrur,

Following up on this thread. Are you still running into this issue? We are going to ask MathWorks to take a look at this post and it may be a few days before they respond. If you have any updates from your side, please do post them here.

Thanks,
Ashwini

Hi Mashrur,

Could you please pass the Model file that is not working for you? Including the version of the MATLAB and the CGT version used. I can then locally try to reproduce the issue. Please provide the linker command file also if it has been modified for your model. Are you running this on a Launchpad?

Regards,

Venkatesh C

Hi Venkatesh,

sorry for the delay. I was able to correct this issue and will close this post. The issue was that I did not correctly map RAM3 in my linker file. The hint about the .word instructions was what I needed to looking into the issue. Thanks for your and Ashwini's help.
