TMS320F28035: CLA not running

Dear Expert

TMS320F28035 encountered the issue of CLA not running. Can it be supported!

After debugging the engineering burning and connecting the target to CLA, and downloading the RUN ->Load ->Load Symbols, the CPU runs at full speed and is displayed on the Debug page, as shown in the following figure:

At the same time, it is displayed on the Disambly interface, as shown in the following figure.

(The next page shows the detailed configuration code)

CLA initialization;



CLA interrupt



CLA trigger source

    Hi Gabriel,

    Can you try connecting in this order:

    1. Comment in the __mdebugstop() line in the CLA task in the .cla file
    2. Launch target configuration
      1. both cores should be disconnected
    3. "Connect Target" for the c28x
      1. c28x will be suspended  
      2. It may throw an error about not having the debug information at this point, that can be ignored
    4. Load the .out file onto the c28x (Run >> Load >> Load Program >> [navigate to the .out file])
      1. c28x will be suspended still
    5. "Connect Target" for the CLA
      1. both cores will be suspended
    6. Load the .out symbols onto the CLA (Run >> Load >> Load symbols >> [navigate to the .out file])
    7. Switch context to the c28x (click on it in the debug window) and Resume
    8. Switch context back to the CLA and you should see it stop at the __mdebugstop();

    Let me know if you have any issues following these steps. Also please make sure you have CLA support enabled in your project properties and that you have selected cla0 (since the TMS320F28035 has a Type 0 CLA).

    Best Regards,

    Delaney

    Hi Gabriel,

    Do you have any updates or further questions? Were you able to get the CLA working in the debugger? Please upvote my previous response if it was helpful.

    Best Regards,
