BOOSTXL-BUCKCONV: Expressions window not updating real time

Hi Mohan,

Can you provide the source code for the runTCM method you have added, or a link to where you are getting it from?

Can you verify if the ISR is executing by adding ISR counter or LED blinking? Sounds like there may be some issue with the runTCM function

Regards,

Peter

Hello Peter,

The following is my fuction that calls the runTCM to load data into pointer space

#pragma FUNC_ALWAYS_INLINE(BOOST_runIsr)
static inline void BOOST_runIsr(void)
{
    //
    // Record the ePWM TBCTR value for informational purposes.
    // The value is helpful for measuring the sum of ADC ACQPS + ISR latency.
    // The value can also help to confirm that enough time has elapsed for
    //   the Vout ADC conversion to complete and arrive in ADCxRESULT
    //
    BOOST_isrEnter_ticks = EPWM_getTimeBaseCounterValue(BOOST_DRV_EPWM_BASE);

    //
    // Record the most recent ADC conversion of Vout
    //
    BOOST_vOutSensed_pu = BOOST_HAL_readVout_pu();

    #if(BOOST_CTL_LOOP == BOOST_CTL_LOOP_OPEN || BOOST_CTL_LOOP_EXT_DUTY)
    #if(BOOST_CTL_MODE == BOOST_CTL_MODE_VMC)
        //
        // Determine the desired duty cycle setting and update CMPA
        //
        BOOST_dutySet_pu = BOOST_dutySlewed_pu; //(float32_t)0.1;  some BOOST_DUTY_SET_MIN_PU required is 0.05 if we set BOOST_DUTY_SET_MIN_PU to 0 in user settings then epwm is getting tripped
        BOOST_HAL_updateSyncBOOSTDuty(BOOST_dutySet_pu);

        //
        // For informational purposes, calculate and record the amount of
        // time remaining before the CMPA shadow load takes place.
        //
        BOOST_logDutyUpdateMargin(); // This is creating problem now tripping the ewpm and stopping further execution which is reading out samples---MN update resolved by comminting DCL_writeLog
    #endif
    #endif

//    #if(BOOST_CTL_MODE == BOOST_CTL_MODE_VMC)
//        BOOST_SFRA_COLLECT(&BOOST_dutySet_pu, &BOOST_vOutSensed_pu);
//    #endif

    BOOST_vInSamples_Volts[BOOST_adcSampleIndex] = BOOST_HAL_readVin_V();
    BOOST_vOutSamples_Volts[BOOST_adcSampleIndex] = BOOST_HAL_readVout_V();
    BOOST_iLSamples_Amps[BOOST_adcSampleIndex] = BOOST_HAL_readFilteredIl_A();
    BOOST_dutyInSamples_pu[BOOST_adcSampleIndex] =  BOOST_HAL_readDuty_pu();
    BOOST_adcSampleIndex++;
    if (BOOST_adcSampleIndex >= BOOST_AVG_ADC_SAMPLES)
    {
        BOOST_adcSampleIndex = 0;
    }
    //DCL_writeLog(&BOOST_vOutLogFdlog, BOOST_HAL_readVout_V());        This is also creating issue like putting the margin into negative and some thing trips the epwm
    DCL_runTCM(&BOOST_vOutLogTcm, BOOST_HAL_readVin_V());
    BOOST_HAL_clearInterruptFlags();
    BOOST_isrExit_ticks = EPWM_getTimeBaseCounterValue(BOOST_DRV_EPWM_BASE);
}

I added method of blinking LED4 at 1sec based on adc sampling rate 200kHz and when I uncomment the line DLC_runTCM(XXX,XX) method then led is not at all blinking. That means BOOST_runIsr is not running to completion cuz hence the sampling of peripherals is not happening becausee adc interrupt is not getting cleared which is written after this line.

Why on keeping DLC_runTCM() into BOOST_runIsr halted my ISR execution which in return not clearing interrupt for further sampling on adc?

Update: I saw I was missing out EALLOW and EDIS lines in my main.c file before and after EINT and ERTM lines. Now I can see the ISR executing and no longer getting blocked by DLC_runTCM() method.

Can I know what really happened? I feel like as I didnt allowed the access to protected registers like INT and RTM I couldnt enabled them and so something went wrong and my DLC_runTCM() was doing something unexpected. Could you please correct me if I am wrong Peter?
