debug CLA F28069

Other Parts Discussed in Thread: CONTROLSUITE

Hello,

I have a Piccolo F28069 ControlStick. For the implementation of CLA functionality i want to debug the program example "Example_2806xClaAdc" from the TI ControlSuite.

I have done everything like in the TI Video from http://www.engineeringtv.com/video/Texas-Instruments-Piccolo-Contr.

In the debug process of my piccolo it is possible to step through the CLA code and the CLA program counter also increases. Unfortunately at the point in ClaTask2 where calculations should be executed, nothing happens. The CLA result registers are filled with zeros.
I can step through the hole CLA code without any changes in the registers.

I even tried an F28035 control card and it is the same problem. I think some configurations in the CCS 4 must be wrong but i have just take the code example and added the configuration file. How can i verifiy that my CLA is working when i don't see any working results in the CLA registers?

best regards

    You could try writing the result of the operations to a variable in the CLAtoCPUMsgRam and then reading on the C28 side. Also check that the MPC is incrementing correctly as you step through the code.

    Also check MVECT2 i.e. the offset of task 2 from 0x9000 and make sure that the code is where it is supposed to be
