RTOS/AM5726: Timer interrupt issue

Part Number: AM5726

Tool/software: TI-RTOS

SDK: processor_sdk_rtos_am57xx_5_00_00_15

Hello,

We want to use timer 15 on processor 5726. To initialize the timer, use the code below

app.cfg

 var Timer = xdc.useModule('ti.sysbios.timers.dmtimer.Timer');
 var IntXbar = xdc.useModule('ti.sysbios.family.shared.vayu.IntXbar');
 var TimerSupport = xdc.useModule('ti.sysbios.family.shared.vayu.TimerSupport');

TimerSupport.availMask |= (0x1 << 14);

IntXbar.connectMeta(47, 341);

Timer.timerSettings[14].intNum = 70;

main.c

Void myIsr15(Void)
{
    Log_info0("myIsr15");
}

static void TimerPRCMConfigure(void)
{
    HW_WR_REG32(SOC_L4PER_CM_CORE_BASE + CM_L4PER3_TIMER15_CLKCTRL, 0x2);

    while ((HW_RD_REG32(SOC_L4PER_CM_CORE_BASE + CM_L4PER3_TIMER15_CLKCTRL) & (0x00030000)) != 0x0) ;
}

Int main() {
    Error_Block eb;
    Error_init(&eb);

    TimerPRCMConfigure();

    Timer_Handle timerHandle;
    Timer_Params timerParams;
    Timer_Params_init(&timerParams);
    timerParams.period = 1000; /* 1 ms */
    timerParams.periodType = Timer_PeriodType_MICROSECS;
    timerParams.arg = 1;
    timerParams.runMode = Timer_RunMode_CONTINUOUS;
    timerHandle = Timer_create(14, myIsr15, &timerParams, &eb);
    if (timerHandle == NULL) {
        Log_info0("Timer create failed");
    }

    BIOS_start();    /* does not return */
    return(0);
}

At debugging In CCS it is visible that the timer 15 goes but function myIsr15 is not called.

When the timer 2 is initialized in function Timer_create instead of timer 15, the function myIsr15 is called up. If you do not turn off the power and running this code with the timer 2 and then run this code with timer 15 - function myIsr15 called. But after turning off the power and running code with timer 15 - function myIsr15 not called

Tell me what to do to make the timer 15 work correctly

Thanks
