TMS320F280049C: DLOG_4CH on CLA

bars yann

Part Number: TMS320F280049C
Other Parts Discussed in Thread: TMDSCNCD280049C

Hello,

I tried to used the DLOG_4CH library on F280049C (via TMDSCNCD280049C ControlCARD).I used the library from DigitalPower_SDK_2_00_01_00. I succeed to use it on CPU but not on CLA.

Is there some specifics code/action to do?

I checked some parts:

my variables are well declared in CLA data that are read/write accessible by CLA & CPU
it seems that the status is still to 1

For information:

CCS Version: 9.3.0.00012
Compiler version: TI v18.12.5.LTS
Optimization level: 2- global Optimizations with speed = 5

If you need extra information, don't hesitate to ask me.

Thanks for your help,

Yann

Yann,

This library was not developed for nor tested on the CLA. A couple of things you may want to try to get it working:

1) There are guards in the code to keep it from being pulled into the CLA code:

#ifndef __TMS320C28XX_CLA__
    //TODO DLOG

    #if INCR_BUILD==1
        // check output voltage and inverter current meas.
        dVal1 = acSine;
        dVal2 = acSine-spll1.sine;
        dVal3 = acSine-spll3.sine;
        dVal4 =ac_cur_sensed;
    #elif INCR_BUILD==2
        // check inverter current meas and reference.
        dVal1 = spll1.sine;
        dVal2 = iL2_sensed;;
        dVal3 = dutyPU;
        dVal4 = ac_cur_sensed;
    #else
        // check inverter voltage meas and reference
        dVal1 = acSine;
        dVal2 = ac_cur_sensed;
        dVal3 = ac_cur_ref;
        dVal4 = spll3.ylf[0];
    #endif
    DLOG_4CH_run(&dLog1);
#endif

2) The issue may be the int16_t in the struct for the DLOG, because we init on C28x and run on CLA. Moving those to 32 may fix the issue.

       float32_t *inputPtr1;
       float32_t *inputPtr2;
       float32_t *inputPtr3;
       float32_t *inputPtr4;
       float32_t *outputPtr1;
       float32_t *outputPtr2;
       float32_t *outputPtr3;
       float32_t *outputPtr4;
       float32_t prevValue;
       float32_t trigValue;
       int16_t status;
       int16_t preScalar;
       int16_t skipCount;
       int16_t size;
       int16_t count;

Best Regards

Lori

Hi Lori,

Thanks for your answer.

I already tested by updating int16_t by int32_t without success. I will made my own debug log for CLA.

Best regards

Yann
