TMS320F280049C: Trip Zone Interrupt CLA Tasks

Hi,

I want to use the CLA, when the trip zone interrupt occurs. Trip zone occurs cycle by cycle. I use CLA_forceTasks inside the tripzone interrupt ISR. But CLA is not working. Variables in CLA is not changing. 

The following code is variables that are transferred between CPU and CLA.

#pragma DATA_SECTION(iL1_sensed_real_poz,"CpuToCla1MsgRAM");
volatile float32_t iL1_sensed_real_poz;
#pragma DATA_SECTION(iL1_sensed_real_neg,"CpuToCla1MsgRAM");
volatile float32_t iL1_sensed_real_neg;
#pragma DATA_SECTION(TTPLPFC_ac_vol_sensed_Volts,"CpuToCla1MsgRAM");
volatile float32_t TTPLPFC_ac_vol_sensed_Volts;
#pragma DATA_SECTION(TTPLPFC_vBus_sensed_Volts,"CpuToCla1MsgRAM");
volatile float32_t TTPLPFC_vBus_sensed_Volts;
#pragma DATA_SECTION(TripZoneCNTR1,"CpuToCla1MsgRAM");
volatile float32_t TripZoneCNTR1;
#pragma DATA_SECTION(grid_direction,"CpuToCla1MsgRAM");
volatile int16_t grid_direction;

#pragma DATA_SECTION(iL1_ort,"Cla1ToCpuMsgRAM");
volatile float32_t iL1_ort;

The following code is CLA configuration.

void setupCLA(void)
{

memcpy((uint32_t *)&Cla1ProgRunStart, (uint32_t *)&Cla1ProgLoadStart,(uint32_t)&Cla1ProgLoadSize);
memcpy((uint32_t *)&Cla1ConstRunStart, (uint32_t *)&Cla1ConstLoadStart,(uint32_t)&Cla1ConstLoadSize );

MemCfg_initSections(MEMCFG_SECT_MSGCPUTOCLA1);
MemCfg_initSections(MEMCFG_SECT_MSGCLA1TOCPU);
while(!MemCfg_getInitStatus(MEMCFG_SECT_MSGCPUTOCLA1));
while(!MemCfg_getInitStatus(MEMCFG_SECT_MSGCLA1TOCPU));

MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS0, MEMCFG_LSRAMMASTER_CPU_ONLY);
MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS1, MEMCFG_LSRAMMASTER_CPU_ONLY);
MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS2, MEMCFG_LSRAMMASTER_CPU_ONLY);
MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS3, MEMCFG_LSRAMMASTER_CPU_ONLY);
MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS4, MEMCFG_LSRAMMASTER_CPU_CLA1);
MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS5, MEMCFG_LSRAMMASTER_CPU_ONLY);
MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS6, MEMCFG_LSRAMMASTER_CPU_ONLY);
MemCfg_setLSRAMMasterSel(MEMCFG_SECT_LS7, MEMCFG_LSRAMMASTER_CPU_ONLY);

MemCfg_setCLAMemType(MEMCFG_SECT_LS0, MEMCFG_CLA_MEM_PROGRAM);
MemCfg_setCLAMemType(MEMCFG_SECT_LS1, MEMCFG_CLA_MEM_PROGRAM);
MemCfg_setCLAMemType(MEMCFG_SECT_LS2, MEMCFG_CLA_MEM_PROGRAM);
MemCfg_setCLAMemType(MEMCFG_SECT_LS3, MEMCFG_CLA_MEM_PROGRAM);
MemCfg_setCLAMemType(MEMCFG_SECT_LS4, MEMCFG_CLA_MEM_PROGRAM);
MemCfg_setCLAMemType(MEMCFG_SECT_LS5, MEMCFG_CLA_MEM_PROGRAM);
MemCfg_setCLAMemType(MEMCFG_SECT_LS6, MEMCFG_CLA_MEM_DATA);
MemCfg_setCLAMemType(MEMCFG_SECT_LS7, MEMCFG_CLA_MEM_DATA);

#pragma diag_suppress=770

CLA_mapTaskVector(CLA1_BASE , CLA_MVECT_1, (uint16_t)&Cla1Task1);

CLA_setTriggerSource(CLA_TASK_1, CLA_TRIGGER_SOFTWARE);

#pragma diag_warning=770

CLA_enableIACK(CLA1_BASE);
CLA_enableTasks(CLA1_BASE, CLA_TASKFLAG_1 | CLA_TASKFLAG_2 );

Interrupt_register(INT_myCLA01, &cla1Isr1);
Interrupt_enable(INT_myCLA01);

}

The following code is trip zone interrupt setup

void setupInterrupt(void)
{

Interrupt_register(INT_myEPWM2_TZ, &INT_myEPWM2_TZ_ISR);

EPWM_enableTripZoneInterrupt(EPWM2_BASE, EPWM_TZ_INTERRUPT_DCBEVT2);
Interrupt_enable(INT_myEPWM2_TZ);

setupCLA();

EALLOW;

//
//Enable Global interrupt INTM
//
EINT;

//
//Enable Global realtime interrupt DBGM
//
ERTM;
EDIS;
}

interrupt void cla1Isr1(void)
{
//
// Acknowledge the end-of-task interrupt for task 1
//
Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP11);

//
// Uncomment to halt debugger and stop here
//
// asm(" ESTOP0");
}

In the following code, iL1_ort is calculated in CLA. But, it is not working.

interrupt void INT_myEPWM2_TZ_ISR(void)
{

TripZoneCNTR1 = (EPWM_getTimeBaseCounterValue(TTPLPFC_HIGH_FREQ_PWM1_BASE) + 1) * CPU_SYS_CLOCK_PERIOD;

duty_ref = TripZoneCNTR1;

CLA_forceTasks(CLA1_BASE,CLA_TASKFLAG_1);

iL1_avg = iL1_ort;

Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP2);
}
