AM5728: bare metal with interrupts

Using the following code to start 2 timiers which will both generate an interrupt after 2 seconds:

    BSP_TMR_Init(eBSP_TMR_GPT_02);
    BSP_TMR_WriteNSec(eBSP_TMR_GPT_02,2000000000);
    BSP_TMR_Start(eBSP_TMR_GPT_02);
    BSP_TMR_Init(eBSP_TMR_GPT_03);
    BSP_TMR_WriteNSec(eBSP_TMR_GPT_03,2000000000);
    BSP_TMR_Start(eBSP_TMR_GPT_03);
    *GICD_ITARGETSR(70)= 3;
    *GICD_ITARGETSR(71)= 3;
    *GICD_ICENABLER(1)= 0xFFFFFFFF;
    *GICD_ISENABLER(2)= 0x000000C0;
    *GICD_CTLR= 0x01;

    *GICC_CTLR= 0x01;                //does not affect pending
    *GICC_PMR= 0xF0;                 //does not affect pending

    for (i=20;i<100;i++) {
        *GICD_IPRIORITYR(i)= 0xF0;
    }
    *GICD_IPRIORITYR(70)= 0x50;
    *GICD_IPRIORITYR(71)= 0x50;
    *GICD_IGROUPR(1)= 0xFFFFFFFF;    //does not set
    *GICD_IGROUPR(2)= 0xFFFFFFFF;    //does not set

    *GICD_ICACTIVER(2)= 0xC0;
    *GICD_ICPENDR(2)= 0xC0;

I see the timers indicate an interrupt after 2 seconds.

Not sure what I am missing- I am not seeing an interrupt being called:

If interrupt vector was wrong I should see a crash - but it appears no interrupt is called

 

I see RPR (running priority) changes is 0x50

I see both interrupts are pending and enabled

GICD_ICPENDR[2]= 0xC0 and  GICD_ICENABLER[2]= 0xC0

GICD_ICACTIVER[2]= 0x40;    //timer2 is active

HPPIR= 0x47;                           //timer3 is highest pending interrupt

Any help would be appreciated.
